Abstract

PURPOSE:To simply perform scan conversion in real time by preserving the maximum value of the picture signal for each picture element as well as renewing the picture signal data every time the frame or scan is changed over and providing afterglow property to the picture signal output. CONSTITUTION:The control signal generator 1 generates the binary control signal inverted every time the frame or scan is changed over, the picture data memory 2 stores the picture data for one frame and the scan data memory 3 stores the scan data for each bit. The switch 4 compares the outputs of the control signal generator 1 and the scan data memory 3 and outputs the output signal of the multiplier 6 when one of them has H level and the other L level and at the same time, outputs the control signal to invert the scan data stored in the scan data memory 3 and outputs the picture data when both the outputs of the control signal generator 1 and the scan data memory 3 have H level or L level. The picture signal memory 2 stores the picture data having the maximum value.
