A detection apparatus detects whether there is flicker attributed to a light source. The apparatus obtains a plurality of captured images related to a subject by performing image capture continuously with use of an image sensor; determines whether a capturing field angle has changed due to an operation of an image stabilizing mechanism during the image capture for the plurality of captured images; and detects whether flicker of a predetermined level has occurred based on the plurality of captured images. In a case where the apparatus has determined that the capturing field angle has changed due to the operation of the image stabilizing mechanism during the image capture for the plurality of captured images, the apparatus restricts regions in the plurality of captured images used for detecting whether the flicker of the predetermined level has occurred.

Detection apparatus capable of detecting occurrence of flicker, image capturing apparatus, control method, and recording medium

An image capturing apparatus comprises an image sensor, a drive control unit for the image sensor, and a detection unit configured to calculate an evaluation value based on second images and detect flicker based on the evaluation value. The drive control unit controls to perform, during a live view cycle of a display device, a first operation for reading out a first image to be displayed, and a second operation for reading out the second images at a second cycle which is shorter than the time taken to read out the first image at timings different from a timing of reading out the first image. Upon calculating the evaluation value based on the second images, the detection unit detects flicker by using different pairs of images from among the second images for calculation of the evaluation value according to the first cycle.

Image capturing apparatus, method for driving image capturing apparatus to detect flicker during shooting

An image capturing apparatus, comprising: an image sensor configured to capture an image of a subject and output image signals, a dividing unit configured to vertically divide the image signals into a plurality of regions, a detection unit configured to detect flicker based on a signal level of each of the plurality of regions, and a control unit configured to cause a plurality of image captures with different exposure conditions to be performed using the image sensor, wherein the detection unit, by adjusting a phase of a flicker appearing in each of the plurality of image signals obtained by the plurality of image captures, detects a flicker from the plurality of image signals.

Image capturing apparatus, control method thereof, and storage medium

An image capturing apparatus includes an imaging element which is capable of simultaneously performing exposures of different exposure times, a detection unit configured to detect flicker; and a control unit configured to control the imaging element such that, in a case where imaging is performed at a frame rate shorter than a period of the flicker, a first image is captured in a first region of the imaging element for a first exposure time which is an exposure time settable in one frame, and a second image is captured in a second region of the imaging element for a second exposure time which is a difference between a time of an integer multiple of the first exposure time and a time of the period of the flicker.

Image capturing apparatus and control method thereof and storage medium

An image capturing apparatus for intermittently acquiring first images for use in generating a time lapse moving image, from among images corresponding to frames included in a moving image. The image capturing apparatus includes a target value setting unit configured to, based on a result of photometry, set a target value regarding an exposure when an image is acquired, a control value calculation unit configured to calculate a control value with respect to each frame regarding the exposure when brightness is changed toward the target value, and a control unit configured to control the exposure based on the control value. In a predetermined period before each first image is acquired, the control unit changes the exposure by a first degree of change, and outside the predetermined period, the control unit changes the exposure by a second degree of change different from the first degree of change.

An image capturing apparatus includes a setting unit configured to set an exposure for image capturing by an image capturing unit, wherein in a mode for acquiring a plurality of images for a moving image by performing intermittent image capturing using the image capturing unit, the setting unit smooths data on a brightness corresponding to a plurality of image capturing operations in the intermittent image capturing and sets an exposure for one image capturing operation in the intermittent image capturing according to the smoothed data, and an acquisition unit configured to acquire first information including at least one of an image capture interval for the intermittent image capturing, a frame rate of the moving image, and shake information during image capturing of a subject. The setting unit determines a degree of the smoothing based on the first information acquired by the acquisition unit.

An image capturing apparatus capable of setting a focus detection area in an imaging range includes a photometry unit, a face detection unit configured to detect a face area, and a photometry area setting unit configured to set a position of a main photometry area. When a user sets the focus detection area and the face detection unit detects a face area, the photometry area setting unit determines whether to set a position of the main photometry area to a position corresponding to the face area or to set a position of the main photometry area to a position corresponding to the focus detection area based on information regarding the face area and information regarding the focus detection area set by the user, and the photometry unit performs photometry on the object based on the position of the main photometry area set by the photometry area setting unit.
