Abstract
A color image processing system is described which provides more realistic hard copy color images from composite video system input signals than previously available. The image processing system includes a synchronization separator 20 which operates to separate the synchronization pulses from the analog video information supplied to it. The analog video information is then converted to digital form by an analog-to-digital converter. The converter operates under control of a time base generator 100, including a programmable delay line 300, which receives synchronization pulses from the synchronization separator, and following a programmable time delay supplies a control pulse to the converter to cause it to sample the analog waveform and convert it to digital format. Once the signal is digitized, it is converted from an additive color system to a subtractive one end enhanced before being supplied to the color plotter 8.
