ABSTRACT:
A video data processing system includes a CPU, a video memory, video data shift registers, a ternary counter, an octal counter, a blanking counter, and a flip-flop. Video data is shifted in the shift registers in response to an output from the ternary counter. The outputs from the ternary counter are counted by the octal counter, and an output from the octal counter is counted by the blanking counter so as to count down a blanking parameter. A borrow output from the blanking sets the flip-flop to hold video data which is then stored in the video memory. This operation is repeated up to the last H along the main scanning direction. The initial value of the blanking parameter is incremented by one by one to repeat main scanning inputs along a subscanning direction.
