The grayscale image image wasn't interpolated from the color image by me . When a color image is taken with the eyemodule, both a color (24-bit UYVY image, ~150k) and greyscale (4-bit, ~37k) record are stored in the image database. I extract both.
The grayscale image shown is 8bit/pixel, but
there is only 4bits/pixel of information. Each pixel is doubled to allow easy conversion. Any additional levels of gray
are merely a side-effect of converting from bitmap to jpeg.
