Abstract
Provided is a photoelectric conversion apparatus for detecting focus, which provides an increased number of ranging points while suppressing a chip-area increase. In a first mode, signals from a first line sensor Lgroup are written in a first line memory Lgroup while signals from a second line sensor Lgroup are written in a second line memory Lgroup. In a second mode, signals from the second line sensor Lgroup are written in the first line memory Lgroup while signals from the first line sensor Lgroup are written in the second line memory Lgroup, so that even one and the same line sensor can select different ranging point regions, enabling provision of an increased number of ranging points while suppressing a chip-area increase.
