Abstract
A solid-state image sensor has a semiconductor substrate and a photoconductive film formed on the semiconductor substrate. The photoconductive film has a charge transfer function and subjects each field or group of picture elements to interlaced scanning. Flicker which otherwise results from inevitable differences between the magnitudes of setting voltages or areas of the photoconductive film portions with respect to the respective fields or groups of picture elements is significantly suppressed by changing the voltages applied to the photoconductive film portions with respect to each field or group of the interlaced picture element.
