Abstract:
1. An image capture device, comprising a shift register including a plurality of pixels to generate information charges in response to light coming from outside and to store information charges generated in response to light of one of two or more different wavelength ranges, each pixel having a plurality of transfer electrodes extending in a direction crossing a transfer direction of information charges, such that a potential well formed by function of the transfer electrodes is used to store and transfer information charges generated in response to light incident on a pixel, wherein during image capture, information charges are stored in a plurality of potential wells substantially separated from each other, during transfer, information charges stored in at least two of the plurality of potential wells in response to light of a same wavelength range are combined by addition in one potential well along the transfer direction to be transferred, the information charges combined by addition are converted into a voltage value and then output, and a group of at least two adjacent transfer electrodes successively arranged along the transfer direction are used as a unit, and a control circuit is provided to supply, during transfer, clock pulses having substantially the same phase to each group of transfer electrodes used as a unit.
