  • Publication number: 20150296129
    Abstract: A focus detection apparatus detects a focus state of a subject using first and second pixel signals obtained by performing photoelectric conversion on subject light beams which have passed through different pupil regions of an imaging optical system. The focus state of a subject is detected from the first and second pixel signals. Further, each of the first pixel signals and second pixel signals are added by a predetermined addition number, and then the added first pixel signals and second pixel signals are relatively shifted. Thereafter, an evaluation value is calculated based on a signal obtained by adding the shifted first pixel signals and the second pixel signals and a defocus amount is detected from the evaluation value. The predetermined addition number is set in accordance with the focus state.
