Abstract: An image captured with flash light and an image captured without flash light are each divided into a plurality of regions, and a luminance value is calculated for each region. Based on a ratio of a difference between the luminance value of each region in the image captured with flash light and the luminance value of the corresponding region in the image captured without flash light to the luminance value of the corresponding region in the image captured without flash light, a degree of influence of light representing the influence of light emitted by the light emitting device on the luminance value of each region in the image captured with flash light is calculated. Regions in which the degrees of influence of light are larger than a predetermined threshold are determined as illuminated regions.

Abstract: An imaging apparatus receive light fluxes passing through and incident on different pupil regions of an imaging optical system and generates at least image data of one pair of subject images. Imaging surface correction information regarding a manufacturing error or optical characteristics of design of an imaging lens is transmitted from a lens control unit of the imaging lens to a system control unit of a camera body, and then the system control unit receives the imaging surface correction information. The system control unit performs a process of generating a defocus map based on a parallax between at least one pair of images and performs imaging surface correction through correction of the calculated defocus amount. In the imaging surface correction process, influences of the optical characteristics of the imaging lens and an inclination of an imaging surface of an image sensor are corrected, and thus a more accurate distance map is generated.

Abstract: This invention encodes, using less memory, a wide-angle image obtained by performing image capturing a plurality of times. An apparatus includes a compositing unit that, each time an image capturing unit captures an image, crops a partial image of a predetermined region in the captured image, and composes the partial image with a composed image obtained from a previously captured image, an encoding unit that, when the composed image updated by the compositing unit has a pre-set size, encodes the image of the tile in the composed image, a releasing unit that releases an area used for the encoded tile in the memory, and a control unit that controls the compositing unit, the encoding unit, and the releasing unit so as to repeatedly perform operations until a pre-set condition is satisfied.

Abstract: An image processing apparatus that properly sets a moving image area according to an image. An image processor generates a combined image, by setting one of a plurality of images as a basic image and disposing a moving image generated from the plurality of images in a moving image area which is designated in part of the basic image. The image processor sets a still area in part of the basic image. A system controller causes the basic image to be displayed on a display section. A user performs a touch operation on the display section displaying the basic image, whereby the moving image area is designated. When the moving image area is designated in a manner overlapping the still area, the image processor performs image combining by deleting the overlapping area from the moving image area.
