Abstract
Official abstract text for this publication.
A shift amount between a plurality of image signals that is obtained from pixels in each of which a plurality of photoelectric conversion units are provided is computed from an amount of correlation based on a difference value between the plurality of image signals. Also, if the difference value that is used for computing the amount of correlation is not less than a predetermined upper limit, a predetermined value that is not more than the upper limit is used as the difference value.
First claim
Opening claim text (preview).
What is claimed is: 1. An image pickup apparatus for processing signals obtained from an image sensor that includes a plurality of pixels in each of which a first photoelectric conversion unit and a second photoelectric conversion unit are provided, the image pickup apparatus comprising: a computing unit which computes a shift amount, which is used for focus detection based on the phase-difference detection method, between a first image signal that is obtained from outputs of the…
