An imaging apparatus according to the present invention includes at least one memory and at least one processor which function as: a first exposure control unit configured to perform first exposure control to suppress overexposure of a captured image; an image processing unit configured to perform image processing to suppress drop in brightness of a low brightness region of the image on a basis of a control amount of the first exposure control; and a second exposure control unit configured to perform second exposure control to bring a brightness of a high brightness region of a captured image closer to a target brightness which is set by a user, wherein in a case where the second exposure control is performed, the first exposure control unit does not perform the first exposure control.

Imaging apparatus configured to perform two exposure controls

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 representative brightness of a high brightness region of an image approaches a target brightness that is set by a user; and a gradation correction unit configured to perform gradation correction to increase a contrast of the high brightness region, by expanding a brightness range of the high brightness region of the image which is captured after performing the exposure control, wherein the gradation correction unit changes degree of the expansion of the brightness range of the high brightness region based on the target brightness.

Imaging apparatus with gradation correction and control method of imaging apparatus

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.

An image processing apparatus includes a composition unit configured to composite a plurality of captured images to generate a composite image, a recording control unit configured to record the captured images or the composite image as a recorded image in a recording unit, and a determination unit configured to determine an imaging mode or a method of composition performed by the composition unit, in which the recording control unit records type data determined on the basis of a result of the determination in association with the recorded image that is captured or composited according to the imaging mode or the method of composition determined by the determination unit.

Image processing apparatus, image processing method, and storage medium

An apparatus includes an imaging unit, a setting unit configured to set automatic modes, an adjustment unit configured to adjust a white balance of a signal based on an automatic mode set by the setting unit, a recording control unit configured to record the adjusted signal into a recording unit, a display control unit configured to display the adjusted signal on a display unit, and an acquisition unit configured to acquire ambient light information, wherein the display control unit further adjusts a color balance of the displayed signal based on the set automatic mode and the acquired ambient light information.

Imaging apparatus, method for controlling imaging apparatus, and storage medium

An image processing apparatus that generates, from a captured image, a color temperature map that indicates color temperature information of light illuminating a captured scene for each area, is disclosed. The apparatus determines, for each area of the captured image, either an interactive light source that has a communication function, a non-interactive light source that does not have a communication function, or both of the interactive light source and the non-interactive light source is a light source that illuminates a corresponding area in the captured scene. The apparatus also generates the color temperature map using a result of determination made by the determining unit, color temperature information acquired from the interactive light source through communication, and color temperature information of the non-interactive light source that is estimated based on the captured image.

An image that is robust against position shift and that has improved graininess is formed. In the embodiments, a halftone processor creates a first dot arrangement and a second dot arrangement from related weighting functions and weighting maps (S, S), evaluates the image quality when the first dot arrangement and the second dot arrangement are overlapped and combined (S, S), updates the weightings for only pixels where a dot is arranged in case where the evaluation results in the evaluating step are not within a specified range (S), obtains a first dot arrangement and a second dot arrangement that were recreated based on the updated weightings (S, S), and repeats steps Sto Suntil it is determined that the change in image quality due to position shift when the recreated first and second dot arrangements are overlapped and combined is within a specified range.
