以下は、GrAndほかの主要コントリビュータが開発した、CHDKの主な特徴です。
These are pretty much "set in stone" and are the main backbone to what CHDK is all about. CHDKプロジェクトは流動的で、 革新的なプログラムであることに注意してください。</br> いくつかの新しいファームウェアについて、使用法を公開しています。(「スペシャルビルド」の項目にあります) 。
to reflect some of the changes that have since been adapted to most everyone's newer builds of CHDK

現在、CHDKはメインの開発者数人によって、新しいレベルに到達しています。 現在AllBestビルドとよばれているビルドには、たくさんの機能が追加されており、 AllBestファームウェアの使い方 をこのWikiに追加しました。 新しい高速シャッター・絞り・ISOオーバーライドが追加されているとともに、TV・AV・ISOおよびフォーカス ブラケットやRAWマージ機能 (加算および平均法選択可能)など、数多い、目を見張る拡張が加えられています。

Keep in mind too that this AllBest's Firmware Usage page is a テンプレート:Color, as the Allbest Build is currently evolving and improving. (The information on that page is also incomplete or sketchy in spots, as we have to depend on online Russian to English translations. If you feel that you can clarify some of the sections, your volunteering as a Wiki editor will be greatly appreciated.)


If you find a feature on your CHDK menus that is not adequately described below, then please refer to the AllBest's Firmware Usage where attempts have been made to clarify and explain all the newest features. This page is ONLY for the original base foundation features of CHDK, (known by all as GrAnd's Builds). If you feel that a CHDK feature isn't fully explained on the Allbest Firmware Usage page, feel free to edit the page accordingly.

CHDKファームウェアの起動画面編集

「起動画面表示」スイッチをオフにしていない限り、CHDKブート後数秒の間、このような画面が現れます。

&lt;ALT&gt; mode

<ALT>モード編集

<ALT>モードに入ると、通常のカメラ操作ボタンなどの機能が無効になり、文字通りalt=代わりの機能になります。
このモードが起動デフォルトでないことに注意してください。

You only need it for the main configuration menu, starting a script and other shortcuts.

<ALT>モードの起動法

<ALT>モードに入るには、ここで選択したボタンを短く押します。To use the button's original function, press and hold the button slightly longer. (Note: this was done to prevent the original <ALT> mode テンプレート:Button button from always interfering with your camera's Shortcut option. Making this adaptable to anyone's preferred method.)
* Default button

<ALT>モードから出るには、<ALT>ボタンをふたたび押します。

メインメニュー編集

CHDKのメインメニューに入るには、 <ALT>モードでMenuボタンを押します。
また、サブメニューに入ったあと、メインメニューに戻るにはDisplayボタンを押します。
メインメニューで設定した値は、メニューを離れるまで有効になりません。メニュー設定中に電源をoffした場合、設定値は破棄されます。

RAWパラメタ・メニュー

RAWパラメタ・メニュー編集

Save RAW

撮影画像をRAW RAW-files フォーマットも保存します。
この機能はショートカット、<ALT>キー++/-からも呼び出すことができます。(PowerShot S-seriesは、<ALT>キー+FUNCボタン)
切り替えは「トグル」になっており、選ばれるたびにon/offされます。ここを確認してください。
G7の場合は、 <ALT>キー+AFフレーム選択/ゴミ箱ボタンになります。
RAW保存時、AシリーズとG7はdirect printボタンの青LEDが一回点滅し、Sシリーズの場合は上面のオレンジLEDが点灯します。ビルド#103から、Sシリーズはさらに、ビジー状態の青LEDも点灯します
ここ には、保存したファイルをPCでRAW現像する方法についての、簡単な解説があります。
ノイズリダクション(CHDKビルド#144以降のみ対応)
注意: この項目で説明するセッティングは、RAW機能とは無関係に、JPG画像ファイルの圧縮にも影響を与えます。
A different type of noise reduction is applied to the raw data when developing. This other type of noise reduction increases with higher ISO and is not affected by this setting.
Auto -- 1秒超の低速シャッターで、自動的に暗視ノイズ減算処理をonにします。
Off -- 暗視ノイズ減算処理を'常にOFFにします。個人的には「わおーっ」な感じ。
この機能で、全シャッタースピードで暗視ノイズ減算処理をカットできます。
S3のRAWモードでインターバル露光を行った場合、15秒露光の4ショットだと、1分20秒ほどかかります。
RAWファイル保存とJPEG圧縮のオーバーヘッドが約5秒なので、各ショットに33秒かかっている計算です。
つまり、約20秒の処理が、この「暗視ノイズ減算」に費やされていることがわかります。この時間を減殺することができれば、稲妻(原文通り)の写真撮影などは、連続RAW同時保存撮影で、75%の時間シャッターが開いていることになり、環境は大きく改善される。
暗視ノイズ減算を止めることによるノイズ増加は、撮影速度向上とトレードオフになるが、フリーウェアの暗視ノイズ減算ユーティリティ、BlackFrame NR で手動で行うこともできる。
あなたが、以下のセッティングにある「高速連写のため先頭のみRAW記録」または「RAW記録off」状態で写すなら、4ショットの15秒露光に、先頭RAW保存なら1分6秒、RAWがoffなら1分4秒しかかからない。
これなら、長時間露光連写で、だいたい95%の時間はシャッターが開いているということになる。
On -- 暗視ノイズ減算処理を常にonにする。.ノイズリダクションのため、シャッターを押したあとに遅延がおきる。
いわゆる「ホット・ピクセル」は、このモードで常時除去されるので、発生しなくなる。
暗視ノイズ減算 (CHDK Builds #136以降)
Camera on long exposures takes the second "dark" shoot which is substracted from the actual picture.

So, by now, only first RAW (before dark frame substraction) was saved. On short exposures it does not matter because there is no dark frame substraction performed. But on long exposures it leads to noisy RAW with lots of hot pixels. Camera uses RAW with dark frame subtracted as a source for its JPEG.
If this new option is activated, the second RAW (with dark frame subtracted), which has less noise, will overwrite the first one. But on the other hand it can lead to E16 error again. 'Use this option if it works for you. If you get E16 errors, deactivate it.

連写時先頭のみRAW保存
Changes the behaviour of RAW saving in continuous shooting mode. When activated you will only get one RAW file, but the following shots will be faster since there is no RAW writing time delay for them.

Voltage MAX(100%バッテリ電圧)
フル充電時のバッテリ電圧を設定します。
(初期値: 5150 = 5.150V)
(G7 ユーザは 8200 を試してください。)
より正確なバッテリ残量%を表示したい場合は: 購入直後のフル充電のバッテリの電圧値を'Show Volts'にて測定し設定してください。('Show Volts'はCHDKのバージョンによってはサポートされていません。).
NOTE: フル充電の3.7Vリチウムイオン電池は無負荷で約4.15Vです。負荷がつながればそれより低い電圧を示します。ですので、この初期値4.1Vではフル充電の場合でも90%程度のバッテリ残量と表示されます。この設定値を若干下げることでより正確な残量%が表示できます。バッテリについてより詳細な情報はhttp://batterydata.com.

Grids

Grid Settings Menu編集

Show Grid Lines
Enable or disable display of composition-assist grids.
Load grid from file ...
Load a "Grid" graphic-command file of your choice, from sub-folder CHDK/Grids/. More information about creating and using them are available here Grid Tutorial and User Contributions
Current Grid
Displays the title of the grid-file presently loaded or in use.
Sample image shows the "Golden Grids" alignment assist in use. Based on various aspects of the Golden Ratio.
Override grid colors (toggle on or off)
Line color Select the color that you want for grid lines when Override is turned on.
Fill color Select the color that you want for filled grid areas when Override is turned on.
This option is handy in situations where you have a compositional grid that you need or like to use but the present lighting or subject makes it difficult to use the predefined grid colors. Instead of rewriting the script to put in new colors (finding/using a computer, et.al.), you can just select new colors right in your camera. For example, if you don't like the transparent-gray that is in the user-submitted cropping grids, you can just select black for the "fill color" and those gray rectangular areas will now be black. Or for the shown example, if you select transparent-yellow for the "Line Color", then all lines in the Golden-Ratio grid will become that color, when Override-grid-color is turned on. This feature is also excellent for testing your final grid colors if you are designing/writing a new grid.

Histogram menu

Histogram menu編集

Show live histogram
Enable display of Live Histogram. There's also a shortcut available to toggle this on/off quickly: In most A-Series and all S-series cameras it is テンプレート:Button+テンプレート:Button, in other more recently ported cameras it may be テンプレート:Button+テンプレート:Button. The Histogram will be shown when you half press the テンプレート:Button button in Rec mode or Playback mode. In more recent builds of CHDK there is now the option to also have the histogram displayed at all times, when enabled.
(Explanation of histograms and how to interpret them. Another good 2-part tutorial on histograms: Tones & Contrast and Luminance (Y) & Color (RGB) Histograms.)
Histogram layout
Select one of the 7 Histogram styles that you want to display.
  • RGB - Red Green Blue
  • Y - Luminance
Histogram mode
Histogram graph scale:
  • linear
  • logarithmic
Show histogram over/under EXP
Displays small warning diamonds in histogram window, and EXP is displayed (when enabled), when there's under or over-exposure.
Ignore boundary peaks
Does not take into account N boundary values during the normalization (scaling) of histogram. For example, if there are overexposure and/or underexposure, left and/or right peaks become large, and the remaining part of the histogram degenerates into thin strip on the bottom during normalization process. The purpose of this parameter is to avoid such situations by not taking into account the specified number of boundary values.
Auto magnify
Provides auto-magnification of the histogram Y-axis data in the event that the current plot covers less than 20% of the histogram plot area. The magnification factor changes dynamically so as to get at least 20% fill, facilitating visual inspection of the histogram. Clipped peaks are markered in red color at the top. A number above the histogram shows the current magnification factor.
Note: The scaling of the histogram plot applies only to the Y-axis (vertical) direction.

Zebra menu

Zebra: blink mode

Zebra: diagonal mode

Zebra parameters編集

Zebra mode is a screen overlay which points out very bright/very dark areas. You can use it like the histogram to avoid over-/underexposure. It is shown in playback mode and record mode when you half press the [shoot] button. You can change the colors of the overlay in the "visual settings" menu.
Draw Zebra
Activates Zebra mode. In some firmware versions there's a shortcut available to toggle this on/off quickly: テンプレート:Button+テンプレート:Button.
Zebra mode
Choose the Zebra mode style.
  • Zebra 1-2 - Draws moving, non-blinking zebra lines.
    1 = thin zebra-stripes, 2 = thick zebra-stripes
  • Blink 1-3 - Draws solid, blinking parts. It will show the normal OSD elements during the pauses of the zebra overlay.
    1, 2, and 3 = number or seconds between blinks.
  • Solid - Draws all light/dark parts of the image in a solid, non-blinking way.
Draw UnderExposure
Choose the amount of underexposure to be shown.
  • 0 = off
  • 1 = show only pure black as underexposed
  • Numbers larger than 1 = show parts which are increasingly brighter as underexposed.
Draw OverExposure
Choose the amount of overexposure to be shown. Again: larger numbers = show more areas as overexposed.
Restore original screen
Restores the original camera icons and exposure information between Zebra mode blinks (when Zebra mode is set to blink).
Restore OSD
Restores CHDK's OSD icons and display information (DOF calc, Histogram, etc.) between Zebra mode blinks.
Draw over zebra
  • Nothing
  • Histo
  • OSD
Enable/disable display of Histogram or OSD-elements while Zebra mode is also being displayed.
Note: Normally if one of the Blink modes is in use and Restore OSD is enabled, you'll only see the histogram during part of the blink-cycle (when the Zebra mode is not visible). These option allow the histogram and OSD elements to be displayed at all times when Zebra mode is also visible -- during the usual half-shutter press, of course.

Script menu

Script menu編集

CHDKではカメラ操作を自動化するために、「スクリプト」を走らせることができます。
これは小さく簡単な、BASIC言語の簡略版のプログラムです。
スクリプトを走らせるには、まずメモリ中に読み込むことが必要です。スクリプトファイルはどんな名前・拡張子でもよく、内容なけが重要です。
読み込まれると、プログラムのタイトルがLCD上に表示されます。このタイトルは、スクリプト中の1行目で定義されたものです。(example: @title Bracketing)
スクリプトは<ALT>モードから、いつでも起動可能です。<ALT>が表示されているとき、シャッターボタンを押すとスクリプト起動、起動中にもう一度押すと割り込みがかかってスクリプトから抜けることができます。
また、<ALT>モードから抜けると、スクリプトの動作を一時的に停止させることができます。 mode, the script resuming right where it left off when you re-enter <ALT> mode. (スクリプトの途中でパラメタを変更するような場合に便利です)
スクリプトの書き方についてはScripting Languageのページを見てください。
There's a shortcut available for the "Script parameters" menu: <ALT> + テンプレート:Button.
Load script from file...
CHDK/SCRIPTS/ フォルダにあるスクリプトをメモリに読み込みます。
Script shoot delay (.1s)
撮影直後、スクリプトが次の動作を実行する前に、短いディレイ(遅延)をかけることができます。
スクリプトがうまく動かないときはこの値を増やし、実行をスピードアップしたいときはこの値を減らしてください。
うまくいかないケースではほぼ、この値設定が問題です。

Script console

Running script

Script mini-console編集
This text is displayed as you run a script. Defined in the script itself by the "print ..." commands. A well-written script will have helpful messages to let the user know what is taking place while it is running or when special instructions are needed..
Special Builds Features編集

Fingalo's (and other's) new builds. See Downloads page for further info.

Autostart
When enabled <ALT> mode is entered and the currently active script-file will start running when the camera is turned on. When using Remote Enable and Autostart the camera will start up (in play mode) at the first press on the USB-remote. If the remote script is active the second press will enter record mode and take a picture. The script must have some command to enter record mode (like shoot or something similar).
Remote Enable
Enable/disable the remote function, ( to be able to download files via USB-cable without turning the SD card write protection off).

Visual settings menu

Visual settings menu編集

Language
Lets you choose another language if you put the appropriate .lng-file in the CHDK/LANG/ folder of your SD card.
OSD codepage
Choose the Codepage.
Menu RBF font
Choose another font (RBF format) for the CHDK menus. If you have chosen a RBF font but want to switch back to the original built-in font, just choose an "illegal" RBF font (Try to load a uBASIC script as a RBF font, for example).
Colors
Change any of the display colors for all your text and icons. If you don't change them they will remain as their defaults. There are opaque colors and transparent colors, and also some "special effect" colors. Note that record mode and playback mode use different color tables. So it may happen that you pick a nice color in playback mode, and in rec mode it will look totally different. But there are also colors which will stay the same in both modes. Some examples for A-series cams: 0x11(white), 0xFF(black), 0x22(red), 0x55(green), 0x44(transparent light grey)

Misc menu

Text file reader
Read any text file on your SD card. Make a sub-directory CHDK/BOOKS/ and put something there to read on vacation.
Games
Reversi, Sokoban
Flash-light
Turns your LCD panel into a flashlight! When in Record Mode and the LCD panel is swiveled facing forward, the LCD display turns all-white so you can see your way around in the dark, or to illuminate some close object to photograph. (Note: In actual use this does not work for photography purposes. The LCD turns dark during the actual exposure. But if you are ever lost on a hiking-trail on some dark and gloomy night, won't you be glad that your camera might save you? :-) )
Show splash screen on load
Shows a splash-screen that the HDK Firmware is loading, for 2.5 seconds.
Use zoom buttons for MF
Use the zoom-rocker switch for adjusting focus in manual focus mode.
A-series: When activated, you can't zoom in manual focus mode.
S-series: Holding down the MF button (while in manual focus mode) allows use of the zoom-rocker for manual focus just as if you were using the テンプレート:Button and テンプレート:Button buttons to focus. Releasing the MF button allows the zoom-rocker to function normally.
<ALT> mode button
(S2 IS and S3 IS only)
Select which button is used to enter <ALT> mode. Can be テンプレート:Button, テンプレート:Button, テンプレート:Button, テンプレート:Button or テンプレート:Button. A short press of your selected button enters/exits <ALT> mode, a slightly longer press to use the button's normal function.
Disable LCD off
Suppresses the camera's "Display Off" energy-saving functions in <ALT> mode. This means that your LCD/EVF screen and camera will stay on permanently instead of turning itself off according to your camera's Power Saving settings.
[No] - LCD/EVF display and camera turns off with the normal camera Power Savings menu settings.
[Alt] - LCD/EVF display (and camera) won't turn off while in <ALT> mode. Also useful if you want to override your auto power-down settings, just enter <ALT> mode.
[Script] - LCD/EVF display won't turn off while in <ALT> mode OR while a script is running. Useful for lengthy intervalometer or other scripts where seeing the display is valuable for important count-down timer or other messages contained in "print" statements. When not set to [Script] mode the script will continue to run and execute its commands, but the display will turn off according to your in-camera Power Saving settings. The LCD/EVF display turning on again whenever the script issues a camera command, as if waking up the camera display manually by pressing any of the buttons. Since the camera is still in <ALT> mode after exiting a script, this will still override your camera's power-down settings.
Use with some caution. If you accidentally leave your camera on while in <ALT> mode and this is turned on your camera will not auto power-down according to your Power Saving settings.
HiCompressed movie (GrAnd's build #148)
Engages a high-compression ratio for all movie modes. File-size ratio being about 1/3rd to 1/4th smaller than normal. Some artifacts and posterizing become visible but the amount of extra time you can get out of each resolution may more than make up for this. Some space saving examples:
640x480, 30fps, 44kHz audio = ~30 minutes, 1G limit
640x480, 30fps, 11kHz audio = ~40 minutes, 1G limit
640x480, 15fps, 44kHz audio = 1 hour time limit
320x240, 15fps, 11kHz audio = 10 to 11 hours video recording space on a 4G SD card.
Especially useful when running scripts for 1-hour video clips for surveillance recording. Or when needing to record audio-only tracks using uBASIC scripts, choosing the lowest resolution video and highest resolution audio for your sound-track. (Audio-only recording is not available from uBASIC script commands so you have to record it as a video then extract the audio track later. Since you'll be throwing away the video for an audio-only purpose the lowest resolution, highest-compressed video will afford the greatest file-size savings per audio recording.)

Choose a rose-colored transparency and view your world a better way. :-) Some of the subtle transparent colors have an interesting shift on the real-world view, acting like special-effects filters. Perhaps future updates of CHDK might make use of this? (Your own extensive special-effects filter library.) Note that color palettes are different for rec mode and playback mode, see here.

Special Build Features編集

The following features have instantly gained popularity and are now appearing in many builds by other authors. See the Downloads section for further information on obtaining these.

Tv Bracketing Value = Off, 1/3EV, 2/3EV, 1EV
This allows you to shoot unlimited exposure bracketing by using shutter speed. The EV value selected will set the desired exposure variation between each shot. When using Continuous or High-Speed Continuous mode in your camera, it will quickly fire-off as many bracketing exposures as you desire. They will be recorded in the following sequence, where X is your starting shutter-speed, and EV is the EV value that you selected:
X, -1*EV, +1*EV, -2*EV, +2*EV, -3*EV, +3*EV, etc...
If during your burst shooting the shutter-speed bottoms out or tops out at the limit of your camera, then it will shoot the alternating exposures no lower nor higher than your camera's limits, but it will continue to alternately increment or decrement at the other end of the EV values. For example, if you started out at 1/800 shutter speed, you would get:
1/800, 1/1600, 1/400, 1/3200, 1/200, 1/3200, 1/100, 1/3200 ...
Note: if you are using a build that also includes the extended shutter speeds up to 65-second exposures, then it will bottom out at that value, and not the camera's native 15-second limit.
Override Shutter Speed = Off, 20", 25", 30", 40", 50", 65"
This will bypass the camera's slowest shutter-speed limit. When set to anything other than OFF your camera will use the selected shutter speed, in seconds. This override affects all other camera settings that will automatically or manually change your shutter-speed (as far as I know), until it is turned off again. Some important things to remember: The shutter speed you select will not be displayed in your EVF/LCD display, it will still show whatever shutter-speed you select using normal camera controls. The only evidence of it working is noticing how much longer it takes to finally write an image to the SD card. The selected shutter-speed also won't appear in the EXIF data, it's always recorded in EXIF as 15" when using any shutter speed of 15" and longer. Remember to turn Override OFF after use, or the next day that you pick up your camera you may wonder why it is doing nothing the first time you press the shutter, but in reality it's taking a 65 second exposure. :-)
It is advisable to use this feature with Noise Reduction turned to OFF (in the RAW options menu), as that actually provides less noise. Instead depend on a nice Black-Frame Subtraction utility to remove any warm or hot pixels from your images. A nice freeware utility may be obtained from Mediachance's BlackFrame NR When these long shutter-speeds are used in conjunction with low ISO80 or ISO100 you may obtain images with little to no noise in properly exposed areas of your images. If you are shooting with NR off it is also advisable to shoot a dark-frame (cap the lens, shoot another shot) as soon as you can after each or every few extra-long exposures, as the randomness of warm-pixels may behave differently over a period of use. If their intensities change over a period of time it will be less effective when using an "old" dark-frame for dark-frame subtraction methods. This seems to be less important at 15-second shutter speeds or shorter.
Any option you select for Noise Reduction (in the RAW menu) will still be applicable to these new shutter speeds. If you choose NR = Auto or On, then a 50 second exposure will take ~100 seconds, 50" for the exposure, 50" for the black-frame that needs to be recorded.
A note of minor interest: You may wonder why these shutter speeds were chosen, and why there's that strange 5 second extra jump for the 65" one. If you do the math you'll find out that these are on 1/3-stop settings. An easy way to understand this is to look at the camera's native 13-second shutter speed. 2X's that would be 26 (25 seconds on the menu), 2X's that would be 52 (50 seconds on the menu). This also accounts for a 15" exposure taking 33" seconds with a dark-frame, 15" is actually 16"+. (2X's 8") The speed choices are not exact but the closest approximation of 1/3-stop steps. The true shutter speed used will reflect true 1/3rd stops rather than the number chosen. If you time a 50" shutter it is approximately 51-52 seconds long. That 5 second jump on the 65" speed is just rounding up for simplifying matters. This is no different than all cameras that used to (and still do) jump from 1/60 to 1/125 for a full-stop, so as to make the next full steps of 1/500, 1/1000 easier to comprehend. If a full-stop shutter-speed beyond was added, it would be on a menu as 2' (minutes) not 130". :)
Video Mode = Bitrate, Quality
Choose between 2 video compression schemes. Selecting the Bitrate option will use the Bitrate settings, selecting the Quality option will use the Quality settings. See the downloads discussion page EWAVR's VideoPlus Version, for more elaboration on this. Options of Bitrate, and Bitrate setting of 1X are the camera's native default compression.
Video Bitrate = 0.25x, 0.5x, 0.75x, 1x, 1.25x, 1.5x, 1.75x, 2x, 2.5x, 3x
A Variable bitrate (VBR mode, constant quality) compression. The size of your video file will change depending on the image content. The more detail and motion in your video, the larger the file-size.
The camera default is 1x.
Video Quality = 1 to 99
A Variable quality (CBR mode, constant bitrate) compression. Every video file will have the same size for the same duration, but it won't compensate for changing image details. Useful when needing the absolute highest compression (least quality), the absolute best in quality (least compression), or when needing to fit a video duration within a certain file-size.
A value of 70 to 75 is about the same compression/quality as the camera's own. A value of 10 is the same as GrAnd's original HiCompressed Movie option (to give you an idea of the image-quality/compression latitude available now).


Note:
When using some of the high-quality settings, VB = 2x to 3x, or VQ = 93 or higher, be sure to use the fastest memory card available. These options easily reach data-rates of 6MBs or more, overwhelming the camera's buffer and/or card-speed. If your camera allows, and you absolutely need the best video quality available, it will help to choose lower audio-quality settings to offset the more massive amount of data being saved in the ultra-high quality video.
Any build of CHDK that has these features also had the 1-GIG file-size limit removed. However there is still the 1-hour limit and a 2-GIG limit. The 2-GIG limit most likely the FAT16/32 limitation on SD/HC cards. Dependable larger file-sizes weren't available until NTFS methods were implemented (i.e. WinXP, etc.) The 1-hour limit being imposed by Canon probably as a CCD over-use safety, as it still exists on all their newer cameras too that don't have the file-size limit.

Debug menu編集

Most options here are used by program developers to view internal memory locations in the camera or code (List of known Property Cases).

However, there is one interesting and one very important option here for the end-user:

Benchmark

Tests the speed of the camera and - more interestingly - the read/write speed of the SD card.
  • Write (RAW) - calculating the speed of saving a data from the address of memory wich contain RAW-image. It saves whole RAW-file size in single chunk.
  • Write (Mem) - the same as above, but the source of a data is just regular memory of the camera (from first 32M address space).
  • Write (64k) - the same as above, but writing a file by small 64Kb chunks.

Make card bootable...

Enable an auto-loading feature for the CHDK firmware add-on. See this section "How to make CHDK Firmware Load Automatically" in the FAQ section.

Reset options

Reset options編集

Reset all CHDK settings to default.

needs clarification -- just resets values in active memory (applied to this power-on session only)? or writes default values to the CHDK config file?

As soon as you leave menu or <alt> mode new options will be saved in config file as well. --GrAnd 19:48, 16 June 2007 (UTC)
