Appendix B
Raspberry Pi Camera Module Quick Reference
THE RASPBERRY PI Camera Module comes with software designed to capture still images and videos, each of which has a variety of options that can control the final output. Options for raspistill, raspiyuv and raspivid are included in this appendix. For more information, see Chapter 16, “The Raspberry Pi Camera Module”.
Shared Options
The following options, listed in alphabetical order, are shared between raspistill, raspiyuv and raspivid. For application-specific options, see the individual raspistill, raspiyuv and raspivid entries later in this appendix.
- -? or --help (Help)—Displays all options and their uses.
- -awb or --awb (Automatic White Balance)—Sets the colour temperature of the captured image or video according to one of a series of preset configurations. If your image or video appears blue or orange, try adjusting this option first. Possible values for this option are off, auto, sun, cloud, shade, tungsten, fluorescent, incandescent, flash, horizon.
- -br or --brightness (Brightness)—Adjusts the brightness of the captured image or video. Possible values for this option are whole numbers ranging from 0 (minimum brightness) to 100 (maximum brightness).
- -cfx or --colfx (Colour Effects)—Allows the user to adjust the YUV colour space for fine-grained control of the final image. Values should be given as U:V, where U controls the chrominance and V the luminance. A value of 128:128 will result in a greyscale image.
- -co or --contrast ...
