Claim:
1. An image pickup device comprising: a pixel unit in which pixels are arranged in a matrix, and, further, when a plurality of the pixels which are adjacent are regarded as unit pixels, the unit pixels are arranged in a matrix, and which generates pixel signals for image and pixel signals for focus detection; a pixel signal synthesizing unit which generates pixel signals for image by synthesizing at least the pixel signals for image generated from pixels within the unit pixels; a first analog memory which stores the synthesized pixel signals for image generated by the pixel signal synthesizing unit when the pixel signal synthesizing unit is disposed before the first analog memory, and at least the pixel signals for image read out from the pixel unit when the pixel signal synthesizing unit is disposed after the first analog memory; a second analog memory which stores the pixel signals for focus detection; and an image signal outputting unit which outputs as image signals, the synthesized pixel signals for image read out from the first analog memory when the pixel signal synthesizing unit is disposed before the first analog memory, and the synthesized pixel signals for image generated by the pixel signal synthesizing unit when the pixel signal synthesizing unit is disposed after the first analog memory, and the pixel signals for focus detection stored in the second analog memory.
