    摘要： An analog front-end circuit includes an analog processing circuit, an A/D converter, a target register in which a lower limit target value of an input image signal is set, and a calculation circuit. The analog processing circuit includes an offset control circuit which performs offset control based on an offset control value set in an offset control register. The calculation circuit monitors the A/D-converted value in a lower limit value output period when the A/D-converted value corresponding to a lower limit value of an input range is output from the A/D converter, and sets the offset control value that causes the A/D-converted value to become closer to the lower limit target value set in the target register in the offset control register.

    摘要： An analog front-end circuit includes an analog processing circuit, an A/D converter, a calculation circuit, and a target register in which a black level target value is set. The analog processing circuit includes a clamp circuit that performs a line clamp operation, and an offset adjustment circuit. The calculation circuit monitors an A/D-converted value of a black reference pixel after the line clamp operation in a black level monitor period after a line clamp period but before an effective pixel output period, and performs a black level error correction process by writing an offset adjustment value that causes the A/D-converted value to be set at the black level target value into the offset adjustment register.
