Title: Automatic gain adjusting circuit
Inventor: FUJII TERUO
IPC: H03G3/20
Filed: 1982-03-03
Abstract: PURPOSE:To attain wide dynamic range and margin against ambient noise, by providing a function which performs automatic adjustment of gain at the conduction of analog switch and keeps a constant gain at interruption for an amplifier. CONSTITUTION:A positive voltage is applied to a terminal 43 before all operations and a capacitor 29 is discharged completely. A negative voltage is applied to the terminal 43 to interrupt a transistor (TR)41. With a terminal 40 applied with a sufficient high voltage, an FET38 is conductive. Thus, when an output 44 of an operational amplifier 44 appears, the capacitor 29 is charged through a diode 31, a resistor, and the FET38. As a result, a terminal voltage 35 is increased, and this voltage is applied to a TR26 via a buffer comprising an operational amplifier 39 and resistors 28, 27. Then, the output of the operational amplifier 34 is reduced. When a signal 19 is small, since the diode 31 is reverse- biased and the TR41 is interrupted, the capacitor 29 keeps a constant voltage without being discharged.

Dimensions of the operation region are set in proportion to the absolute value of the speed variance vector. Thus, the operation time for the coefficient of correlation is independent of the number of picture elements of a picture to be correlated, and pictures of the standard television scanning system are correlated and tracked in real time.
