A video digitizer for the Amstrad CPC from Rombo Productions.

Scanning Modes

The software supports 3 modes (at hardware side, there are only 2 modes):

• Mode 2 - 640x200x1 - true hardware mode
• Mode 1 - 320x200x4 - true hardware mode
• Mode 0 - 160x200x16 - special mode: the software performs sixteen Mode 2 scans (with different brightness settings in each pass), and combines them to a 16-color image. Obviously, this method works only with still images (camcorder aimed at still image, or VCR with "freeze picture" mode). Moreover, the CPC with CTM640/CTM644 colour monitor can't display 16 grayscales so the picture will look like crap, however, it will look pretty much perfect on a GT64/GT65 green monitor.
