Abstract:
A method for driving a solid state image pickup device having a plurality of unit pixel means where each one of the plurality of unit pixel means corresponds to a pixel means having at least one input converting section, and CCD electric charge transfer means, the method comprising the steps of:setting a first signal charging period and a second signal charging period during a field of a video signal for each one of the plurality of unit pixel means, where the second signal charging period is shorter than the first signal charging period;setting, during the field, the second signal charging period of a first unit pixel means and the second signal charging period of a second unit pixel means so that the second signal charging periods for the first and second unit pixel means have different start times and similar time duration, the first and second unit pixel means are adjacent to each other in a vertical direction, each one of the first and second unit pixel means adjacent to each other in the vertical direction produce first signal charges during the second signal charging period; andmixing the first signal charges during a transfer operation using the CCD electric charge transfer means to produce a mixed signal charge.
