PURPOSE:To prevent the error from being produced in the output, by performing the read and the write of the output of the field memory at different timings for output buffer registers to compensate the defect side of this memory. CONSTITUTION:Field memory Mf is constituted with, for example, CCD and has input register Ri, main memory Mm, and output register R0. Switch circuit S1 is switched at every 1H by control circuit CC, and clock pulses for writing are supplied synchronously with the video signal of terminal Ti to registers R1 and R2 or registers R3 and R4, and the video signal is written into registers R1 and R2 and registers R3 and R4 at every 1H alternately, and their outputs are supplied to memory Mf. The read and the write of the output of memory Mf are performed at different timings for output buffer registers R5-R8 to compensate the defect side of memory Mf. As a result, the error is not generated in the output. |
