  • Publication number: 20240022829
    Abstract: An imaging apparatus includes at least one memory and at least one processor which function as: an exposure control unit configured to perform exposure control so that a representative brightness of a high brightness region of an image becomes a target brightness set by a user; and a tone correction unit configured to perform tone correction on a captured image, which was captured after performing the exposure control, based on a brightness of a dark portion that is a region having a brightness lower than the high brightness region, wherein the tone correction unit adjusts a correction amount of the tone correction so that the representative brightness of the high brightness region, which is corrected to be higher than the target brightness by the tone correction, becomes close to the target brightness.

  • Patent number: 11593925
    Abstract: A method includes detecting a gradation area in an input image, and performing, based on a detection result acquired by the detecting, for an area that is not the gradation area, gain processing on the input image by using a gain based on a first gain characteristic in which different gains are set depending on luminance values, whereas performing, for the gradation area, gain processing on the input image by using a gain in which an amount of change in gain with respect to a change in luminance value is more reduced than the first gain characteristic.

  • Patent number: 9781351
    Abstract: A zooming control device includes a first determination unit configured to determine whether a current state is a specific image capturing state in which a photographer can perform self photographing, a zooming control unit configured to, in a case in which it is determined that an image does not satisfy a predetermined composition condition, perform zooming control so as to satisfy the predetermined composition condition, and a reception unit configured to receive a predetermined operation for instructing an image capturing preparation operation. The zooming control unit performs the zooming control in a first state in which the predetermined operation is not received, and in a case in which the first determination unit determines that the current state is the specific image capturing state, the zooming control unit continues the zooming control even in a second state in which the predetermined operation is received.

  • Publication number: 20150163391
    Abstract: An image capturing apparatus analyzes an image shot by a shooting unit and processes the image based on an analysis result. The apparatus analyzes a standby image generated during shooting standby before an instruction of shooting to detect an object from the standby image, and performs bracket shooting for the detected object using a shooting condition set for each object in accordance with the instruction of shooting. The apparatus also analyzes a plurality of bracket images to detect an object region including the object from each of the plurality of bracket images, to perform determination for each detected object region in association with the shooting condition, and to select at least one bracket image out of the plurality of bracket images for each object region according to the determination result. The apparatus executes image processing on the selected bracket image for each object region.
