YUV 4:2:2 output is normally associated with color cameras, but in this case, it is avail-

able on A620

f monochrome cameras. When an A620f is set for YUV 4:2:2, its output

will be in the YUV 4:2:2 format but the output will be monochrome, not color. This

monochrome version of the YUV 4:2:2 format is provided so that the camera can be

used with Windows XP accessories such as Movie Maker.

When an A620f is set for a standard mono mode that outputs 16 bits per pixel, the cam-

era outputs 16 bits for each pixel but only 10 of the bits carry actual pixel information.

The 10 effective bits fill from the LSB and the unused bits are filled with zeros. Pixel

data is stored in the PC memory in little endian format, i.e., the low byte for each pixel

is stored at the lower address and the high byte is stored at the neighboring higher ad-

dress.
