摘要： There is provided an image capturing apparatus comprising an image sensor that outputs a plurality of parallax images in a single instance of shooting, the parallax images having different viewpoints. A shooting control unit carries out, using the image sensor, first shooting and a plurality of instances of second shooting. The plurality of instances of second shooting is carried out under a shooting condition in which a depth of field is shallower than in the first shooting. A generating unit generates a plurality of range images corresponding to the plurality of instances of second shooting. A detection unit detects an amount of positional skew, relative to a first image generated through the first shooting, of each of a plurality of second images generated through the plurality of instances of second shooting.

摘要： An image capture apparatus has an image sensor and an optical anti-shake mechanism that reduces a shake of a captured image by driving an optical correction element in a different direction from an optical axis of an imaging optical system in accordance with a detected shake. Reference coordinates for geometric deformation processing applied to the captured image are determined based on an amount and direction of a movement of the optical correction element. The geometric deformation processing is applied to the captured image using these reference coordinates and an amount of geometric deformation based on the detected shake. Coordinates of the captured image corresponding to an intersection of the optical axis and the image sensor after the optical correction element is moved through the driving are determined as the reference coordinates.

摘要： The number of images to be composited used to generate a dynamic range-extended image, and exposure conditions for respective images to be composited are determined. A proper exposure condition is determined for a subject corresponding to a moving object region, and one of the exposure conditions of the images to be composited is changed to the proper exposure condition. An image capture apparatus specifies a moving object region for a plurality of images to be composited, which are captured under the exposure conditions of the images to be composited including the proper exposure condition. A dynamic range-extended image is generated using pixels of the image to be composited, which is captured under the proper exposure condition, as those of the moving object region, which is specified for the plurality of images to be composited.

摘要： In an image pickup apparatus, a parallax image acquisition unit acquires data of a plurality of viewpoint images having different viewpoints from an imaging unit. A detection unit detects the amount of change in a position or an attitude of the imaging unit which has generated the data of the plurality of viewpoint images. A calculation unit calculates a correction quantity of a shake correction unit and a mixture ratio of images when an image compositing unit generates a composite image from the plurality of viewpoint images on the basis of the amount of change in a position or an attitude of the image pickup apparatus. The image compositing unit generates a composite image from the plurality of viewpoint images using the calculated mixture ratio. The shake correction unit corrects image shake of the viewpoint images or the composite image according to the calculated correction quantity.

摘要： An image processing apparatus includes at least one processor operatively coupled to a memory. A first anti-shake unit executes an anti-shake process on image data relating to a captured image, and to record image data after the anti-shake process on a recording unit. A second anti-shake unit executes a re-anti-shake process while performing a control process of removing influence of the anti-shake process, which adversely affects the re-anti-shake process executed by the second anti-shake unit, executed by the first anti-shake unit on the image data, after the anti-shake process recorded on the recording unit, based on auxiliary information regarding the anti-shake process output by the first anti-shake unit.
