Color Image Processing

Some remarks for choosing the right color image format

The storage of a Bayer pattern image requires no more memory than that of a black-and-white image with the same dimensions. It is, however, not very convenient for image processing. It is therefore recommended, to convert the Bayer pattern image into a different color image type. We suggest using the YCbCr 4:4:4 format, but other formats like RGB or ISH (HIS) will do as well. YCbCr444 or RGB require three times the memory space compared to the Bayer format and can be viewed directly on the screen (COLOR_MODE = DISP_YCBCR or DISP_RGB). If live display is required, the user may wish to view the original Bayer pattern memory using COLOR_MODE = DISP_BAYER or DISP_BAYERGREY The YCbCr422 format requires twice as much storage space as the Bayer format and is required for color JPEG conversion. The YCbCr411 has the lowest memory requirements except for IMAGE_BAYER.
