To provide an image pickup apparatus capable of shortening, when a still image is picked up, a time during which a live view (LV) image is not updated.
The image pickup apparatus includes a pixel section in which pixels 28 each including a photoelectric conversion portion PD and a signal storage portion FD that temporarily stores a signal charge of the photoelectric conversion portion PD are two-dimensionally arrayed. The image pickup apparatus resets the signal storage portions FD before exposing a still image and reads reset data used to remove reset noise of the still image. The image pickup apparatus is configured to divide the pixel section into a plurality of pixel groups and sequentially reset the signal storage portions FD of the respective pixel groups by a transistor Mr, sequentially read reset signals by a selection transistor Mb and cause the selection transistor Mb to read one or more times an LV signal charge generated by exposure of a prescribed pixel group within a time segment during which the signal storage portions FD are sequentially reset before the signal storage portions FD of the prescribed pixel group are reset.
