ABSTRACT:
An image capture device includes a plurality of image capture elements for capturing an object image, a plurality of vertical output lines for reading signals out of the plurality of image capture elements, and a plurality of processing circuits. Each processing circuit includes a first capacitor element having a first electrode connected to one of the plurality of vertical output lines, a differential amplifier having a first input terminal connected to a second electrode of the first capacitor element, a second capacitor element connected between the first input terminal and an output terminal of the differential amplifier, and a first switch configured to control conduction between the first input terminal and the output terminal of the differential amplifier. The image capture device further includes a plurality of third capacitor elements configured to hold signals from the differential amplifiers of the plurality of processing circuits and to limit an output frequency band of each differential amplifier, and a horizontal output line for sequentially outputting signals from the plurality of third capacitor elements.
