Abstract: A photoelectric conversion device includes a plurality of unit pixels each including a charge holding portion to which charges are transferred from four or more photoelectric conversion units. Sensitivity of each photoelectric conversion unit of a first group to incident light is greater than sensitivity of each photoelectric conversion unit of a second group to the incident light. After charge accumulation is started in all the photoelectric conversion units of the second group, charge accumulation is started in the photoelectric conversion units of the first group. After signals corresponding to charges accumulated in all the photoelectric conversion units of the second group are read out, signals corresponding to charges accumulated in the photoelectric conversion units of the first group are read out.

Abstract: In an image pickup apparatus using an image pickup element including a plurality of photoelectric conversion means sharing a microlens, the number of pixels to be read is switched between the case of normal photographing and the case of live view driving. In the case of live view driving, only pixels positioned near the center of the optical axis of the microlens, the number of which is smaller than that in the case of normal photographing, are read. The image pickup apparatus realizes both normal photographing capable of acquiring an image in which the depth of field is small and which can be refocused, and live view photographing capable of displaying an image with a large depth of field and the high frame rate, thereby allowing the framing of the photographed image to be confirmed.
