Abstract: A photoelectric conversion device has a plurality of pixels each of which is configured to include a sensor unit that generates a pulse at a frequency corresponding to a photon reception frequency, and a counter that counts a number of the pulses. The plurality of pixels are controlled such that a signal is generated based on a difference between count values for the counter between a start time and an end time for a plurality of different accumulation periods within a full frame period, and such that an image signal that is generated during a first accumulation period is output between a time from an end of the first accumulation period until an end of a second accumulation period. In addition, the photoelectric conversion device generates a mapping parameter and performs tone mapping processing on the image signal using the mapping parameter.

Abstract: 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.
