Abstract: An imaging element incorporates a processing circuit and a memory. The memory stores captured image data obtained by imaging a subject at a first frame rate. The processing circuit performs processing based on the captured image data stored in the memory. An output circuit outputs output image data based on the captured image data to an outside of the imaging element at a second frame rate. The first frame rate is a frame rate higher than the second frame rate and is determined in accordance with an occurrence cycle of a flicker, and the processing circuit detects a flicker effect avoidance timing at which an effect of the flicker on imaging by the imaging element is avoided, based on the captured image data of a plurality of frames.

Abstract: A system control unit consecutively images a subject by driving based on a global shutter method, divides captured image data obtained by the imaging into a plurality of areas, and each time each area is generated, compares the generated area with the same area as the area in the captured image data generated by the imaging performed before the imaging, and detects a moving object from the area based on a result of the comparison. Based on a change in position of the detected moving object, the system control unit predicts a timing at which a trigger range TR set in the captured image overlaps with the moving object, and performs automatic imaging in a frame period that includes the timing.

Abstract: A digital camerathat includes an imaging sensor having a stop 2 arranged in front of an imaging surface includes an imaging control unit that starts exposure of pixels on the entire imaging surface at the same time and then, ends the exposure of the pixels at the same time in a state where light from a subject is incident on the imaging surface, by controlling an imaging sensor drive circuit which drives the imaging sensor, and a processr that sequentially changes an F number of the stop 2 to a plurality of values during a period from the start of the exposure until the end of the exposure. The processr controls a time in which the F number is maintained at each of the plurality of values to be a time that is based on a function indicating light transmittance characteristics of an APD filter.

Abstract: Provided is a technique capable of correcting unique shading characteristics of a single-eye stereoscopic imaging device. A focal length is acquired. A one-dimensional correction table corresponding to the focal length is acquired from a plurality of stored one-dimensional correction tables. Shading correction is performed using the acquired one-dimensional correction table. An arbitrary pixel is selected from main pixels, a correction value corresponding to the position of the selected pixel is read from the acquired one-dimensional correction table for the main pixel, and shading correction is performed for the basis of the correction value and the value of the arbitrary pixel. This process is performed for all of the main pixels and the sub-pixels. A two-dimensional SD correction unit performs normal shading correction for the data subjected to the shading correction using a two-dimensional correction table.
