Digital Video



3. Digitalization



IRIS's video board VINO takes NTSC video signal and after digitalization can achieve spatial resolution of 640*480 pixels, quantization of 8 bits/pixel (256 shades of gray) and a frame rate of 4 frames/s.

The Sun Video digitizer from Sun Microsystems capture NTSC video signal in the form of the RGB signal with frame resolution of 320*240 pixels, quantization of 8 bits/pixel, and a frame rate of 30 frames/s.
