Abstract
The present invention is an image pickup apparatus provided with a pixel section in which pixels each including a photoelectric conversion section and a signal storage section that temporarily stores a signal charge of the photoelectric conversion section are two-dimensionally arrayed, that resets the signal storage sections before exposing a still image and reads reset data used to remove reset noise of a still image, configured to divide the pixel section into a plurality of pixel groups and sequentially reset the signal storage sections of the respective pixel groups by a transistor, sequentially read reset signals by a selection transistor and cause the selection transistor to read one or more times an LV signal charge generated by exposure of a predetermined pixel group within a time segment during which the signal storage sections are sequentially reset before the signal storage sections of the predetermined pixel group are reset.
