An imaging apparatus includes: a plurality of photoelectric converters each adapted to perform photoelectric conversion in response to receiving light, and output an electrical signal; a holding unit adapted to hold, for each of the plurality of photoelectric converters, a correction value for correcting photoelectric conversion characteristics of the photoelectric converter; and a correction unit adapted to correct each of the electrical signals output by the plurality of photoelectric converters, using the corresponding correction values, wherein the correction unit corrects each of the electrical signals based on the correction values, which have been increased or decreased in accordance with a prescribed pixel arrangement pattern, and the imaging apparatus comprises a determination unit adapted to evaluate correction results that are based on the correction values increased or decreased in accordance with the prescribed pattern, and determine a presence of a correction error in the correction values held in the holding unit.
An imaging apparatus comprising:
An imaging apparatus comprising:
A control method of an imaging apparatus that includes a plurality of photoelectric converters each adapted to perform photoelectric conversion in response to receiving light, and output an electrical signal, and a holding unit adapted to hold, for of the plurality of photoelectric converters, a gain correction value for correcting photoelectric conversion characteristics of the photoelectric converters, comprising:
A non-transitory computer-readable medium storing a computer program, the computer program causing an imaging apparatus that includes a plurality of photoelectric converters each adapted to perform photoelectric conversion in response to receiving light, and output an electrical signal, and a holding unit adapted to hold, for the plurality of photoelectric converters, gain correction values for correcting photoelectric conversion characteristics of the photoelectric converters to execute:
