Title: Digital agc circuit
Inventor: MARUYAMA JIYUNJI
IPC: H03G3/00
Filed: 1984-03-07
Abstract: PURPOSE:To obtain a stable operation by providing a dead band around an output level with a comparison circuit and a selection circuit, multiplying a prescribed coefficient with a level error in excess of a deal band width and controlling the gain based on the result. CONSTITUTION:An output of a pre-stage variable gain amplifier 21 is outputted from an A/D converter 23 via a sample-and-hold circuit 22. A digital signal at each sampling is squared by a power calculation circuit 24 and a mean value of N times is outputted. Then the result is applied with decibel conversion by a logarithmic converting circuit 25. A subtractor 26 calculates the difference between a real AGC output and a reference level. A coefficient is multiplied with the error output, the gain of the amplifier 21 is controlled by an output of a multiplier 27 and a stable AGC operation is obtained. A selection circuit 28 selects the coefficient. When the comparator circuit 32 detects that the output of the subtractor 36 is within a dead band width not responsive within a prescribed range, a selection circuit 29 gives a zero output zeroing the input signal. When the width is at the outside of the dead band, the signal is given to the output of the multiplier 27 so as to apply feedback.

Abstract: PROBLEM TO BE SOLVED: To eliminate line crawl due to nonuniformity of a photosensing characteristic of light receiving pixels provided to a color image pickup device. SOLUTION: A pixel signal S outputted from a color image pickup device 2 is converted into pixel data P by a sample-and-hold circuit 4 and an A/D converter 6 and the data are stored in an image memory 8.

The line crawl correction factor LC is decided in advance and the light receiving pixels whose photosensing characteristic is nearly equal are grouped (classified) and arithmetic mean of signals of the grouped light receiving pixels is obtained and a ratio of the arithmetic mean is used for the line crawl correction factor.
