Abstract
A solid-state imageroutputs image signals corresponding to picture elements received from light-receptive areas thereof. A sample-and-hold circuitperforms a sample-and-hold operation for the image signals at prescribed times. A driving circuitgenerates driving pulses and sample-and-hold pulses. A horizontal charge-transfer circuit of each light-receptive area is driven with the driving pulses, and the sample-and-hold circuitis driven with the sample-and-hold pulses in synchronization with the driving pulses. The driving circuitintermittently drives the horizontal charge-transfer circuit and the sample-and-hold circuit after the output of at least one of the first and last image signals. Consequently, noise that would be produced in picture elements located at the junctures between adjoining light-receptive areas can be reduced, and loss of image quality that would be caused by the effects of operations in subsequent processes performed in various circuits can be reduced.
