ABSTRACT:
A focus detection apparatus includes an image sensor that applies photoelectric conversion to incident light and accumulates charge, a first output unit that outputs electric signals based on the charge accumulated in the image sensor through multiple channels, and a focus detection unit that detects a phase difference on the basis of the electric signals outputted from the plurality of channels.
