Abstract: An imaging apparatus captures a first image with a first exposure time, captures a second image with a second exposure time shorter than the first exposure time, and determines either the first image and the second image as an image to be used for the calculation of a motion vector depending on a result of the detection of flicker based on the first image and the second image. Then, the imaging apparatus calculates a motion vector based on the determined image.

Abstract: An image processing apparatus that records image data on a detachable storage medium in a previously set recording format is provided. The apparatus sets the recording format of image data, and determines whether or not a storage medium attached to an attachment unit has a communication function that communicates with a different apparatus than the image processing apparatus. If it is determined that the storage medium has a communication function, and that the recording format of image data that can be transferred by the communication function does not match the recording format that has been set, the apparatus issues a warning.

Abstract: An image capturing apparatus includes a driving control unit configured to control driving of an image sensor, and a flicker detection unit configured to detect flicker, which is a periodic change in a light amount of an object, based on a signal output from the image sensor, wherein the driving control unit is configured to, if the image sensor outputs a flicker detection signal to be used in detecting the flicker, control the driving of the image sensor at n different frame rates, n being a natural number greater than or equal to 3, wherein a least common multiple of the n frame rates used in detecting the flicker is not same as any of the n frame rates, and wherein the flicker detection unit is configured to detect the flicker based on the flicker detection signal obtained at each of the n frame rates.

Abstract: An apparatus comprises: a sensor that shoots a subject and outputs an image; a shift unit that shifts a position on the sensor of an image of the subject incident on the sensor; and a detection unit that detects flicker based on partial images in a same partial region of a plurality of images consecutively obtained from the sensor. In a case where the sensor shoots the plurality of images while the shift unit is shifting the position of the image of the subject, the detection unit selects the partial region so that a change of the image of the subject in the partial region caused by the shift becomes small between the plurality of images.

Abstract: An imaging apparatus includes a photometric sensor, and can continuously acquire a plurality of images by a single imaging operation. A CPU for image processing and an arithmetic operation acquires image data output by a photometric sensor and performs photometric processing. The CPU determines presence or absence of a flicker light source using a plurality of pieces of acquired image data, and calculates a motion vector of an object by comparison of image data. If it is determined that there is a flicker light source in a photographing environment, gain adjustment is performed on the basis of a result of flicker detection so as to have a brightness of an image suitable for detection of a motion vector, and the motion vector is calculated using image data after gain adjustment.

Abstract: There is provided with an image pickup apparatus including a detection unit configured to perform a flicker detection operation to detect flicker based on a plurality of images captured by an image sensor, and a control unit configured to control the image sensor based on detected flicker information. The detection unit configured to perform first detection of the flicker detection operation at a time that is different from a time at which an image pickup preparation instruction is received and different from a time at which an image pickup instruction is received whilst live view images are displayed. In the case that a flicker is detected in the first detection, the control unit configured to control exposure of the image sensor in a charge accumulation period to reduce an influence of the flicker for live view display on display means after the first detection.

Abstract: An image pickup apparatus that performs, when photographing an object, photographing by causing a light emission device to emit light to the object. A photometry sensor selectively obtains a first image having a first resolution and a second image having a second resolution lower than the first resolution, as a photometric image, and performs photometry using the obtained photometric image to thereby obtain a result of photometry. When performing light control processing for determining a main light emission amount for causing the light emission device to perform main light emission for photographing the object, the light control is switched between first control for performing light control processing based on the first image and second control for performing light control processing based on the second image, according to a result of determination of whether or not a predetermined condition is satisfied.
