Abstract: An imaging element incorporates a memory and a processor. The memory stores image data obtained by performing imaging at a first frame rate. The processor is configured to output the image data at a second frame rate. In addition, the processor derives shake degree information indicating a degree of shake included in an image indicated by the image data, using the image data, and outputs the derived shake degree information at a rate greater than or equal to the second frame rate. The first frame rate is a frame rate greater than or equal to the second frame rate.

Abstract: An imaging element incorporates a reading portion that reads out captured image data at a first frame rate, a storage portion that stores the image data, a processing portion that processes the image data, and an output portion that outputs the processed image data at a second frame rate lower than the first frame rate. The reading portion reads out the image data of each of a plurality of frames in parallel. The storage portion stores, in parallel, each image data read out in parallel by the reading portion. The processing portion performs generation processing of generating output image data of one frame using the image data of each of the plurality of frames stored in the storage portion.

Abstract: An imaging element includes a reading circuit that reads out pixel data obtained by imaging a subject at a first frame rate, a memory that stores the read pixel data, and an output circuit that outputs image data based on the stored pixel data at a second frame rate. The first frame rate is a frame rate higher than the second frame rate. The pixel data includes phase difference pixel data and non-phase difference pixel data different from the phase difference pixel data. The reading circuit reads out the pixel data of each of a plurality of frames in parallel within an output period defined by the second frame rate as a period in which the image data of one frame is output, and performs reading of the non-phase difference pixel data and a plurality of reading of the phase difference pixel data within the output period.

Abstract: In an imaging element in which a plurality of phase difference detection pixels and a plurality of normal pixels for imaging are two-dimensionally arranged in a horizontal direction and a vertical direction, the phase difference detection pixel includes a first phase difference pixel ZA and a second phase difference pixel ZB including opening portions for pupil separation at different positions in the horizontal direction. The first phase difference pixel ZA and the second phase difference pixel ZB are adjacently arranged to have the opening portions facing each other. RGB color filters are arranged in the plurality of normal pixels in the Bayer arrangement. The imaging element includes a normal pixel row in which only the normal pixel is arranged in the horizontal direction and a phase difference pixel row in which the first phase difference pixel ZA, the second phase difference pixel ZB, and one normal pixel are periodically arranged in the horizontal direction.

Abstract: An imaging apparatus and an image processing method capable of increasing correction accuracy of a phase difference detection pixel even in a case where the phase difference detection pixel is densely arranged in an imaging element in order to secure AF performance are provided. An imaging element includes normal pixels of RGB and first and second phase difference pixels of which opening portions are adjacently arranged to face each other in a horizontal direction and in which a G filter is arranged. A pixel value addition unit (64) generates an addition pixel corresponding to a virtual G pixel at a pixel position between the first and second phase difference pixels by adding pixel values of the pair of the first and second phase difference pixels. In a case where the first or second phase difference pixel is set as an in-focus pixel that is an interpolation target, an average value interpolation unit (62) uses the normal pixels surrounding a pixel position of the in-focus pixel and the addition pixel in a case of performing an interpolation operation on a pixel value at the pixel position of the in-focus pixel.
