Abstract

PURPOSE: To attain a simple constitution and to easily control by adding a reproduced signal to the difference between a reference lamp signal and a reproduced lamp signal as a corrected value and compensating the characteristic of a recording and reproducing system.
CONSTITUTION: At the time of recording, the lamp signal is recorded in a part including no video signal such as a vertical blanking period. When a time base corrector (TBC)1 outputs the reproduced lamp signal, a signal of the same waveform as the lamp signal at the time of recording is generated from a reference lamp generating circuit 2 and the difference between a level at the time of recording and a level at the time of reproducing appears in the output of a subtracter 3. Then, the output of the subtracter 3 is written as the corrected value in a memory 5 by making the output off the TBC1 an address. At the time of reproducing an ordinary video signal, the output of the TBC1 is added to the address of the memory 5 to read the corrected value, the output of the TBC1 and the corrected value are added by an adder 6, thereby, a characteristic corrected reproduced output is obtained.
