Claim:
1. An image pickup apparatus comprising: an image sensor configured to include plural pixels in a first direction with respect to a microlens and a second direction orthogonal to the first direction to photoelectrically convert paired object images passing through an image capturing optical system, at least two photoelectrical convertors being formed on each of the plural pixels in the first direction; a signal producing part configured to produce paired image signals corresponding to the paired object images; and a calculating part configured to calculate a second correlation data, wherein the calculating part is configured to shift the paired image signals relatively in the first direction, configured to produce a plurality of first correlation data showing change of a correlation value of the paired image signals according to their relative shift amount in the first direction, the plurality of first correlation data corresponding to a plurality of areas in the image sensor, and configured to combine the plurality of first correlation data for producing second correlation data.
