Abstract
PURPOSE: To obtain a still picture of high dignity without using a dropout memory by providing a one-frame memory element for the storage of a VTR signal and then by storing the same picture signal in this element twice or more.
CONSTITUTION: When a still picture is reproduced by VTR1, a signal of one frame or one field period "0" is applied to terminal 22 and by this signal, memory command signal 26 is outputted to memory element 13. At this point in time, a dropout part is also stored in the memory element at the same time. For the 2nd reproduction, memory command signal 26 is so outputted that it will all be stored in any other period than the dropout period. In the dropout signal part which was not stored at that time, a previously-stored picture signal resides, so that a picture with its dropout compensated, when read from memory element 13, will be obtained.
