Abstract
An integrated circuit for processing an analog image signal obtained from a CCD, etc. and converting the processed image signal to a digital image signal. The integrated circuit includes a circuit for adjusting an offset voltage included in the analog image signal, a circuit for sampling/holding the image signal from the adjusting circuit, a variable amplifier for varying an amplitude of the image signal output from the sampling/holding circuit, an analog/digital converter for converting the image signal from the variable amplifier to a digital signal, and a circuit for detecting a DC component included in the digital image signal and providing the detection result to the adjusting circuit. Correction of a DC voltage component of the analog image signal and amplitude adjustment of the analog image signal can be performed by using a single LSI, and the LSI can be connected to various types of CCDs without using an additional circuit.
