Information processing apparatus and method

An image capturing apparatus and a control method thereof relate to an image capturing apparatus such as a camera array. The image capturing apparatus comprises a plurality of image capturing units. An image capturing unit to be activated out of a plurality of image capturing units is decided based on the capturing distance of an object included in a captured scene. Electricity is supplied to the image capturing unit decided to be activated.

Method of controlling image capturing based on a distance to an object

A plurality of image capturing data time-divisionally exposed by a capturing unit are input, and are divided into synthesis images or motion detection images. A motion amount of the capturing unit at the time of time-division exposure is detected from the image capturing data of the motion detection images, and synthesized image capturing data is generated by synthesizing the synthesis images. Then, a vibration of the synthesized image capturing data is corrected based on a divide pattern indicating divisions, and the motion amount.

Information processing apparatus and method for correcting vibration

An image processing apparatus executes a distortion correction on coordinates of a target pixel in a virtual viewpoint image based on distortion characteristics of a virtual camera and calculates coordinates in the virtual viewpoint image after the distortion correction. The image process apparatus calculates ideal coordinates in a captured image from the coordinates in the virtual viewpoint image after the distortion correction and calculates real coordinates in the captured image from the ideal coordinates in the captured image based on distortion characteristics of an imaging unit. The image process apparatus calculates a pixel value corresponding to the real coordinates from image data of the virtual viewpoint image and corrects the pixel value corresponding to the real coordinates based on ambient light amount decrease characteristics of the imaging unit and ambient light amount decrease characteristics of the virtual camera.
