Abstract
From each of a plurality of picture element cells having a non-destructive readout characteristic, arranged two-dimensionally and connected to the same signal output line, an image signal is read out without mutual interference of the picture elements. To this end, a blanking period is provided between the readout periods of the respective picture element cells connected to the same signal output line and, in this blanking period, the signal output line is cleared (refreshed).
