  • Patent number: 10523860
    Abstract: A plurality of pairs of image signals each constituted by a first signal obtained by performing photoelectric conversion on light flux that passes through a first pupil area in the exit pupil of an imaging optical system and a second signal obtained by performing photoelectric conversion on light flux that passes through a second pupil area are generated. The plurality of pairs of signals differ in the correlation amount of noise components of the first and second signals constituting the pairs of signals. One of defocus amounts obtained from the pairs of signals is used to adjust the focus distance of the imaging optical system. Accordingly, a focus detection device that can suppress the influence of correlated noise included in the pairs of image signals on focus detection and a control method thereof are obtained.
