ABSTRACT:
In a solid state imaging device having a group of pixels arrayed in the form of a matrix, after a vertical scanning circuit delivers a drive signal for one first switching element, a horizontal scanning circuit is driven to sequentially read out pixel signals from the respective pixels on one predetermined row line to a signal output line, and one second switching element connected to another row line, from which pixel signals have been read out one horizontal scanning period before the readout for the predetermined row line, is driven to reset the respective pixels connected to another said row line upon the driving of the horizontal scanning circuit. Both the readout and reset operations for the respective pixels are point-sequentially performed so that periods of time integrating the pixels at all the positions on the imaging device can be made equal to each other.
