Claim:
1. An apparatus comprising: an image sensor that has a plurality of sensor chips having photoelectric conversion elements and that outputs pixel signals from the plurality of sensor chips through a plurality of output channels; an identifying unit that identifies a width of a document to be read by the image sensor; and a signal control unit that controls signals to be output from the image sensor, wherein, in the image sensor, different sensor chips at an interval of a number of channels of the output channels are connected to each output channel, and wherein the signal control unit controls whether to output a pixel signal from each sensor chip based on the document width and whether to receive an end pulse of a previous sensor chip as a start pulse of each sensor chip, and wherein the identifying unit and the signal control unit are implemented by at least one processor.
