Patent JP-S6377272-A (JP)
Title: Signal correcting device
Inventor: MATSUOKA HIROKI
IPC: H04N5/235
Filed: 1986-09-19
Abstract: PURPOSE:To obtain a TV standard signal in which the maximum value of the amplitude level of an output video signal is always made constant by providing an adding device to add a video signal and a necessary signal, an non-linear converting device and a signal processing device. CONSTITUTION:When the maximum value of the amplitude level of an input video signal 105 is smaller, a microcomputer 104 makes the value of an adding signal 106 and a subtracting signal 107 into zero. Consequently, the maximum value of the amplitude level of the input and output signal of a non-linear converting device 1 02 comes to be 0A and 0A' and the maximum value of the amplitude level of an output signal 108 from a subtracting device 103 comes to be also 0A'. Next, the same value of the signal 105 is larger and is 0Q, the value of the signal 106 is made into 0P. Since 0P=QB is obtained, the same value of the input signal to the device 102 comes to be PB and an input output characteristic is preserved. At this time, the same value of the output signal is P'B'. Value 0P is set so that P'B'=0A' can be obtained, 0P' corresponding to this is given as the signal 107, and in this case, the same value of the signal 108 from the device 103 comes to be also 0A'. Consequently, the same value of the signal 108 can be always constant.
