Abstract:
1. An imaging device, comprising: a sensor chip including: a plurality of pixels arranged in a 2-dimensional matrix; and a plurality of data output terminal groups, each of the data output terminal groups being made UP of a plurality of data output terminals which output signals of the pixels; a same number of signal processing chips as data output terminal groups, each signal processing chip including: a data input terminal group electrically coupled to one of the data output terminal groups; a processing unit which performs processing on the signals of the pixels received by the data input terminal group, and the processing unit including a plurality of A/D converters which convert analog signals into digital signals; and a control unit which controls operation of the processing unit and operates in synchronization with control units of other signal processing chips, wherein: the control unit of at least one of the plurality of signal processing chips includes an A/D conversion control circuit which controls operation of the plurality of A/D converters, the control unit of at least one of the plurality of signal processing chips has a timing generator which controls a driving timing of the sensor chip, controls the operation of the processing unit, and controls operation of the sensor chip, a simple A/D conversion control circuit is provided in signal processing chips not having the A/D conversion control circuit, and a simple timing generator is provided in signal processing chips not having the timing generator, the simple diming generator generating a test signal for testing the signal processing chips alone.
