IMAGING APPARATUS AND CONTROL METHOD FOR SAME

摘要

An imaging apparatus includes an imaging element having pixel portions each having a plurality of photoelectric conversion units for each microlens. The imaging element can output a pixel signal depending on a pupil-divided light flux. An image processing LSI processes a video signal based on the pixel signal output from the imaging element. An imaging element control unit controls the operation of the imaging element. An exposure control unit performs exposure control for an optical lens unit and an imaging element. In the first mode, the operation for reading pixel signals from all of the plurality of photoelectric conversion units constituting the pixel portion of the imaging element is performed. In the second mode, the control for reading pixel signals from a part of the plurality of photoelectric conversion units and for stopping a circuit relating to the unused photoelectric conversion units by reading no pixel signal is performed.

主权项

1. An imaging apparatus that performs focus adjustment control by pupil division-type phase difference focus detection, the imaging apparatus comprising:
an imaging element configured to output a pixel signal from a pixel portion having a plurality of photoelectric conversion units for each microlens; an image processing unit configured to process the pixel signal output from the imaging element; and a control unit configured to control reading of the pixel signal from the imaging element and image processing performed by the image processing unit, wherein the control unit has a first mode for reading pixel signals from all of the plurality of photoelectric conversion units constituting the pixel portion and a second mode for reading pixel signals from a part of the plurality of photoelectric conversion units and controls to stop a circuit relating to the photoelectric conversion units from which no pixel signal is read in the second mode.
