ABSTRACT:
A solid-state imaging device of a three-transistor pixel configuration having no selection transistor has a problem of a non-selection hot carrier white point, which is specific to this apparatus. A bias current during a non-reading period of pixels is made to flow to a pixel associated with an immediately previous selection pixel, for example, the immediately previous selection pixel itself. As a result, dark current only for one line occurs in each pixel, and the dark current for one line itself can be reduced markedly. Consequently, defective pixels due to non-selection hot carrier white points can be virtually eliminated.
