Title: Peak value detector for digital picture signal
Inventor: FUKUDA SATOSHI
IPC: H04N1/407
Filed: 1987-11-30
Abstract: PURPOSE:To attain stable peak value detection by providing a time constant depending on a value X so as to allow a detected peak value to follow a digital picture signal. CONSTITUTION:A digital subtractor 25 makes subtraction of a digital picture signal (a) and an output data (f) of an attenuator circuit 30 and outputs a difference and its sign. A selector circuit 26 selects an output data (b) of the subtractor 25 as an output data (c) when a sign output of a subtractor 20 is given and gives a value of c=0 when the sign output is not given. The circuit 30 outputs a value (f) being 1/X of an output data (e) of a data latch circuit 28. A digital adder 27 adds the data c, e. The circuit 28 latches the data (e). A data latch circuit 29 latches an output data (f) of the circuit 30 at the transit point of an AGC enable signal from ON to OFF and its output data (g) is outputted externally from an output terminal 35 as a peak value.
