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>
to reflect some of the changes that have since been adapted to most everyone's newer builds of CHDK
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.
<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.)

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.
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.
Compare R1 and R2 to the the actual focus distance (F) to see which parts of your picture will still be in focus. Set your focus point (F) to the hyperfocal distance (HYP) and everything from some near distance to infinity will be sharp.
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.
Select one of the 7 Histogram styles that you want to display.
RGB - Red Green Blue
Y - Luminance
Histogram graph scale:
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.
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 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.
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.
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.
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).
Restores CHDK's OSD icons and display information (DOF calc, Histogram, etc.) between Zebra mode blinks.
Draw over zebra
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.
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..
Fingalo's (and other's) new builds. See Downloads page for further info.
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).
Enable/disable the remote function, ( to be able to download files via USB-cable without turning the SD card write protection off).
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).
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)
Some fun and and some extremely helpful things you can do or use.
See what files are on your SD card.
A handy perpetual calendar to look up dates.
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.
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.
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:
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.)
Can be used to test the colors and transparencies for use with menus, icons, and fonts. Or you can just enjoy all the pretty colors. Are you having a bad day? 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.
You can download fonts here or here or add you own fonts using the RBF Editor. Hint: If you have many fonts in many sizes and attributes, put all the files of the same font in sub-folder named for that font. Then you can just open each font's folder to select a new size, instead of tediously scrolling through dozens and dozens of fonts in all their sizes and attributes. A real time-saver to help in selecting the most legible font.
When exiting it memorizes the last-viewed position of the text, setting a bookmark.
This does not work when you just power off the cam - you have to exit the reader and the CHDK menu.
When using the "Open last opened file" option your viewing will resume right where you left off. This bookmark is discarded when loading a new/different file.
You can use テンプレート:Button/テンプレート:Button and テンプレート:Button/テンプレート:Button and テンプレート:Button for navigation in the text reader. You can use the テンプレート:Button button to pause autoscroll if it is enabled.
Old screenshot -- the text reader now wordwraps lines by complete words
You have to push your orange boxes and leave them on blue destinations. When an orange crate is placed on a blue destination it will turn yellow. When all your boxes are on a destination spot and have turned yellow you have won that round. Level 1 requires 108 moves. Level 2 requires 107 moves. Can you do it? There's 116 games/levels. (Just in case you are curious, level 116 requires 207 moves.)
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:
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:
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.
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).
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.
