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: A digital camera includes an imaging control unit that images a subject by performing driving based on a rolling shutter method on an imaging sensor, and a light emission control unit that emits auxiliary light a plurality of times from a light emission device while the imaging is performed. A difference At between start timings of exposure started by the driving in two adjacent pixel rows is a value other than 1/n (n is an integer greater than or equal to 1) of an exposure time in which the exposure is performed. The light emission control unit controls a light emission cycle of the auxiliary light to be a time that is m (m is an integer greater than or equal to 1) times the difference.

Abstract: An imaging apparatus includes an imaging element and a second processor. The imaging element incorporates a memory which stores image data obtained by imaging at a first frame rate, and a first processor configured to output the image data at a second frame rate independent of the first frame rate. The image data is input into the second processor from the first processor. The first processor is configured to acquire positional information indicating a position of an image recognition region set as a processing target of image recognition processing in the image data. The second processor is configured to perform the image recognition processing on the image recognition region based on the positional information.
