Abstract: PURPOSE: To obtain a picture with good quality without being affected with temporary dropout or noise by sampling a picture signal of the identical scanning position for plural number of times and operating the data to obtain a sampling data of the scanning position.
CONSTITUTION: Horizontal and vertical synchronizing signals in an input video signal are separated, the horizontal synchronizing signal is delayed for a prescribed time, a sampling signal is outputted to a sample-and-hold circuit 11, where the signal is sampled and held, the holding value is stored in an internal storage memory 31 of a microprocessor 3 and one vertical period is finished. A digital signal data on the same picture position is stored again in the memory 31. When the data for two times' share are compared and they are coincident, the data is transferred to a picture processing circuit 4. The amount of delay of a delay circuit 14 is changed and the process is moved to the sampling of the next vertical line. If they are not coincident, the operation is repeated again.
