IMAGE CAPTURING APPARATUS AND STORAGE MEDIUM FOR STORING IMAGE CAPTURING CONTROL PROGRAM

摘要

An image capturing apparatus includes a light emission controller configured to make a light emitter provide a first light emission and a second light emission with a light emission amount calculated based on a result of photometry in the first light emission, the light emitter being configured to emit illumination light of the object field, and a switch configured to switch a readout of an exposure control signal between first and second signal readouts to obtain a result of the photometry in the first light emission. In the first signal readout signals from a plurality of photoelectric conversion elements are synthesized and read out. In the second signal readout, an output of a first photoelectric conversion element is read out among a plurality of photoelectric conversion elements in an image sensor and then an output of a second photoelectric conversion element is read out.

主权项

1. An image capturing apparatus comprising:
an image capturer having a plurality of pixels each including a plurality of photoelectric conversion elements for each micro lens; a reader configured to read a signal from the pixel by a first signal readout in which signals from the plurality of photoelectric conversion elements are synthesized and read out, and a second signal readout in which an output of a first photoelectric conversion element is read out among the plurality of photoelectric conversion elements and then an output of a second photoelectric conversion element is read out; a photometer configured to provide photometry using a signal read out of at least a part of pixel area that has received light from an object field; a light emission controller configured to make a light emitter provide a first light emission and a second light emission with a light emission amount calculated based on a result of the photometry in the first light emission, the light emitter being configured to emit light to illuminate the object field; and a switcher configured to switch a readout of an exposure control signal from the pixel area, between the first signal readout and the second signal readout so as to obtain a result of the photometry in the first light emission.
