Abstract
In the method of driving a solid-state image sensing device, for each vertical blanking (VBL), the signal charges of a first pixel group composed of photosensitive pixels of odd ordinal numbers counted in the vertical direction of the photosensitive region and the signal charges of a second pixel group composed of photosensitive pixels of even ordinal numbers counted in the same way are reversed in the vertical transfer direction, so that the signal charges of the first and second pixel groups can be outputted from the same charge detecting circuit for each field. Further, unnecessary accumulated charges in the pixel groups in the photosensitive region are cleared off in response to an accumulated charge clear pulse. Further, it is also possible to equalize the photoelectrically converted output voltages of the two charge detecting circuits to each other, by equalizing the charge accumulation periods of the first and second pixel groups to each other on the basis of a third FS pulse (accumulated charge clear pulse).
