Abstract: A technique is disclosed to calculate a new pixel value of a particular color of second-viewpoint color image data in such a manner that a difference between the new pixel value of the particular color of the second viewpoint and the pixel value of the particular color of the first-viewpoint color image data maintains correlation with a sum of a difference between the pixel value of a first color component of the second-viewpoint color image data and the pixel value of the first color component of third-viewpoint color image data and a difference between the pixel value of a second color component of the second-viewpoint color image data and the pixel value of the second color component of the third-viewpoint color image data.

Abstract: To produce both 2D image data and color parallax image data from image data output from a single-plate image sensor, the resolutions of the 2D image data and parallax image data may be both degraded. The image sensor has a primitive lattice that is a group of pixels including (i) at least four types of parallax pixels formed by photoelectric converter elements each of which is associated with one of combinations of two different types of aperture masks and two different types of color filters and (ii) no-parallax pixels configured to guide an incident luminous flux to photoelectric converter elements without limitation. In the group of pixels, the no-parallax pixels are more than the parallax pixels.

Abstract: With a conventional stereoimage capturing device, it has been difficult to simply determine the present of a depth. An image capturing device includes an image capturing element in which a first parallax pixel group and a second parallax pixel group that output a first parallax image and a second parallax image, respectively, to cause a parallax are arranged at mutually different positions. The image capturing device computes a differential pixel value of each of a plurality of second parallax output pixels in the second parallax image positioned around a target pixel that is a first parallax output pixel of the first parallax image, the differential pixel value being computed with reference to the target pixel, and generates differential data in which a direction of each of the plurality of second parallax output pixels with reference to the target pixel is associated with the corresponding differential pixel value.
