摘要： An image capturing apparatus includes an image sensor that has a plurality of two-dimensionally arrayed pixels, each of the pixels having a first photoelectric conversion portion and a second photoelectric conversion portion, a generation unit that generates a first image signal by connecting, in a pupil divided direction, a first signal obtained by combining signals of the first photoelectric conversion portions, and generate a second image signal, in the pupil divided direction, a second signal obtained by combining signals of the second photoelectric conversion portions. In a case of combing signals of the first photoelectric conversion portions, or combining signals of the second photoelectric conversion portions, the generation unit decreases weighting of a signal of a photoelectric conversion portion in which an effect of crosstalk from a neighboring photoelectric conversion portion is large.

摘要： An imaging device and an imaging method are provided. An incident beam is separated into a first spectroscopic beam and a second spectroscopic beam by a spectroscopic unit and the first spectroscopic beam and the second spectroscopic beam are respectively incident on a first imaging module and a second imaging module. One of a phase detection autofocus (PDAF) mode and a contrast detection autofocus (CDAF) mode of the first imaging module is activated based on a brightness of an ambient light source. The first imaging module and the second imaging module are activated to shoot at a partially overlapping field of view (FOV) to obtain a first image and a second image. The first image and the second image are superimposed to obtain a composite image.
