Abstract
PURPOSE: To decrease the bit number of the memory by converting the picture information into the analog color signals and then memorizing them into the analog memory.
CONSTITUTION: The analog color signals obtained by converting the picture information into the analog signals are supplied through terminal A and then memorized into analog memory 20. These analog color signals are then delivered through terminal A' and supplied to level comparators 31W34 as well as to NOT circuits 35W38. The output of NOT circuit 35 is supplied to black color signal terminal BL0 and NOT circuit 39; the output of AND circuit 42 is supplied to blue color signal terminal B0; and the output of NOT circuit 36 is supplied to NOT circuit 40 and AND circuit 42 respectively. In the same way, the output of AND circuit 43 is applied to red color signal terminal R0, and the output of AND circuit 44 is supplied to white color signal terminal WO.
