Abstract

PURPOSE: To correct signal missing owing to drop-out, etc. by interpolating the field signal before one horizontal section when the signal missing section is detected.
CONSTITUTION: When it is detected that the input data of a line 2-2 is wrong, arrangement is so made that no write signal is emitted, and writing of the input data of the line 2-2 is stopped. When the error has been detected, the one which is read out from this address is the data of the line 1-11. Namely, the field line b1-11 before 1H spacially with respect to the error line b2-2 becomes the interpolating line. And the input data of the second frame are subsequently written into a memory device 1.
