Abstract: A method and device for capturing a mixed structured-light image and regular image using an integrated image sensor are disclosed, where the structured-light image is captured using a shorter frame period than the regular image. In order to achieve a shorter frame period for the structured-light image, the structured-light image may correspond to an image captured with reduced dynamic range, reduced spatial resolution, or a combination of them. The capturing process comprises applying reset signals to a pixel array to reset rows of pixels of the pixel array, reading-out analog signals from the rows of pixels of the pixel array and converting the analog signals from the rows of pixels of the pixel array into digital outputs for the image using one or more analog-to-digital converters.

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.
