Abstract: An image pickup apparatus that enables to quickly capture an image from which a predetermined reflected light component is removed with desired sensitivity. A polarizing filter two-dimensionally arranges a plurality of sets each of which includes polarizing filter elements having different polarization directions. A first image sensor has pixels that respectively correspond to polarizing filter elements of the polarizing filter. A polarization calculation unit detects a polarized component of light that enters into a region in which one set of polarizing filter elements are arranged based on signals output from pixels in the region of the first image sensor for each region. A correction unit corrects a pixel signal output from a pixel of a second image sensor corresponding to the region based on a calculation result by the polarization calculation unit for each pixel of the second image sensor.

Abstract: Provided is an apparatus including: first and second photoelectric converting portions; a charge detecting portion; a transistor outputting a pixel signal first and second sampling and holding capacitors; an amplifier; and a controlling unit controlling gain in first and second mode. The pixel signal is one of: a first signal at time of resetting of charge; a second signal including a charge component of the first photoelectric converting portion and a noise component; and a third signal including the first component, a charge component of the second photoelectric converting portion and a noise component. In the first mode, the controlling unit uses a first gain. In the second mode, the controlling unit uses second gain to the first signal, third gain to the third signal of the first sampling and holding capacitor, and second gain to the third signal of the second sampling and holding capacitor.

Abstract: An image processing technique that enables accurate detection of a flicker component even when applied to an image pickup device capable of changing a driving method on a region basis within a frame. A flicker detection section detects a flicker component of an image pixel signal read out from the image pickup device having a pixel region for detecting a phase difference. When the driving method is changed to one for performing phase difference detection, the flicker detection section detects a flicker component such that the period of the flicker component in a region used for phase difference detection within the frame coincides with a period of the flicker component in a region not used for phase difference detection.
