A photoelectric conversion apparatus having a plurality of pixels each including a photoelectric conversion element and a plurality of first holding portions, comprises a control unit that controls a charge accumulation period in the photoelectric conversion elements in units of predetermined minimum controllable period, and a setting unit that sets a charge accumulation period in one frame period. The control unit controls to transfer charges from the photoelectric conversion elements to the first holding portions in turn a plurality of times during each frame period, and controls the charge accumulation period in the photoelectric conversion elements such that a difference between the set charge accumulation period and a total of divided charge accumulation periods for accumulating charges to be transferred the plurality of times in each frame period becomes shorter than the minimum controllable period.

In an image processing apparatus, an image signal of a plurality of polarized lights is input, for each set of image signals corresponding to the polarized lights, a maximum value of polarization intensities of polarization components of the image signals and a polarization angle at which the maximum value of the polarization intensities is obtained are found, and a target area to which polarization reduction is to be applied is found based on the image signal and a statistical area is set in the target area. Representative intensity and angle which are modes of the polarization intensities and angles of the sets included in the statistical area are found, and first correction processing for correcting each image signal of the sets included in the target area is performed using the representative intensity and angle according to the polarization angle of the each image signal.

Image processing apparatus and method, and image capturing apparatus

A photoelectric conversion device includes pixels each including a photoelectric conversion unit for generating charge by photoelectric conversion, first to fourth charge holding portions configured to be transferred charge from the photoelectric conversion unit, and an output unit for outputting a signal corresponding to charge transferred from one of the first to fourth charge holding portions, and a control circuit for controlling the plurality of pixels. The control circuit performs, during one frame, transferring charge in the photoelectric conversion unit to the first or second charge holding portion a plural times for each of the first and second charge holding portions in each of the pixels at the same time, and performs, during the one frame, reading out from each pixel a signal corresponding to charge in the third charge holding portion and a signal corresponding to charge in the fourth charge holding portion.

A seesaw type operation unit having a new configuration is provided. A swinging member is capable of swinging in a predetermined direction with a rotation axis at a center. An urging member urges the swinging member to a neutral position. A detector includes a rotating portion which is arranged coaxially with the rotation axis and rotates integrally with the swinging member, and outputs a signal depending on a rotation amount of the rotating portion. An operating member receives an operation from an outside and causes the swinging member to rotate in the predetermined direction by the operation. A supporting member rotatably and coaxially supports the swinging member and the operating member. In a case where the operating member is rotated in the predetermined direction, the operating member pushes an end of the swinging member to rotate the operating member, the swinging member, and the rotating portion integrally with one another.
