摘要： An optical device comprises an image sensor having plural pixels and a detection unit configured to detect a focus state. The pixels include first focus state detection pixel pairs that respectively receive a pair of light fluxes having transmitted different pupil areas of the photographing lens, and second focus state detection pixel pairs that respectively receive a pair of light fluxes having transmitted pupil areas shifted by a predetermined amount from the pupil areas where the pair of light fluxes received by the first focus state detection pixel pairs have transmitted. The detection unit detects the focus state based on signal pairs obtained by adding the signals output from the first and second focus state detection pixel pairs, respectively, if a subject to be photographed is darker than a predetermined brightness, otherwise the detection unit detects the focus state based on signal pairs output from the first and second focus state detection pixel pairs, respectively.

摘要： In an image sensor having a plurality of pixels which photoelectrically convert a subject image, a plurality of pairs of focus detection pixels including first focus detection pixels (SHA) and second focus detection pixels (SHB) are arranged while being distributed. The layouts of the first focus detection pixel (SHA) and the second focus detection pixel (SHB) are switched in pairs of focus detection pixels adjacent in the focus detection direction. Focus detection is performed using image waveforms obtained from the first focus detection pixel (SHA) and the second focus detection pixel (SHB) whose layouts are switched. This reduces focus detection errors generated when the pixels included in the pairs of focus detection pixels receive light fluxes from different portions of the subject.
