Abstract
By flexibly coping with both image sensors of a CCD sensor and a CMOS sensor without providing any external circuit, a signal processing is performed. In a sensor selecting switch provided in an image-sensor signal-processing circuit, first and fourth switches are turned on when the CMOS sensor is connected, and second and third switches are turned on when the CCD sensor is connected. The sensor selecting switch is controlled by a control signal generated in a control circuit, based on sensor selection data which is stored in a register and which is data for selecting the CCD or CMOS sensor. By so doing, even if polarity of an output signal of the image sensor is reversed, a normal signal is inputted to both inputs of the CDS amplifier, whereby it is possible to flexibly cope with both of the CCD and CMOS sensors.
