Abstract
A timing pulse generator for generating timing pulses exhibiting vertical and horizontal scanning frequencies of the type found in video signals, particularly adapted for use with a CCD imaging device. A first counter counts reference pulses having the horizontal scanning frequency to produce address counts that are used to read out timing pulse data stored in a first ROM, the read out data constituting a portion of the timing pulses. A second counter counts reference pulses of a frequency substantially higher than the horizontal scanning frequency to produce second address counts which are used to read out pulse data stored in a second ROM, the read out data constituting another portion of the timing pulses. Two separate ROMs are used to produce timing pulses of the horizontal and vertical scanning frequencies for driving and reading image data from the CCD device.
