The Minton Probe e.2000 camera , (also known as the Genius 1.0 camera and other random names) despite it's name and information in the manual appears to be (from the files it writes) only a 1024 by 768 (ie 800k pixel) camera. The images are (before compression) as a one layer deep 1024x768 8 bit image in the usual scan order. Different pixel correspond to R, G and B. Starting at the top left the raster is tiled with 2x2 sqaures as follows.

The eye is more sensitive to green The images are the compressed using a propreitry compression algorythm, which truncates the depth and uses some sort of RLE. My code is in 5 parts
 

• genius.c - which downloads thumbnails and full images from the camera.
• decompress.S which links with decomp.c - is the decompression code.
• decomp.c - call decompress.S
• thm2ppm.c - which converts interleaved thumbnails to ppm format
• int2ppm.c - which (badly) converts interleaved full images to ppm format
• Makefile - which does everything for you

run the Makefile to make the parts. genius will download everything from the camera. The Makefile will then convert the thumbnails using thm2ppm < in > out, and also the full images using decomp < in | int2ppm > out.
you can get the whole lot as a tar ball here....
