Abstract: An image pickup device includes a horizontal inversion section 6 for horizontally inverting at least a third one of first to third pixels signals to be outputted from individual CCD units 2a to 2c corresponding to R, G, and B, and a CCD actuation control section 9 capable of controlling the first to third CCD units 2a to 2c so that pixels, 2n+1 (n=0, 1, 2, . . . ) in each set, in a horizontal direction are subjected to the pixels addition set by set. The CCD actuation control section 9 performs control such that the second pixel signal is subjected to the pixel addition at timings delayed by n pixels with respect to timings for the first pixel signal, and the third pixel signal is subjected to the pixel addition at timings delayed by n pixels with respect to the timings for the second pixel signal. With this image pickup device, a high-sensitivity image can be obtained with the resolution impairment being suppressed.
