Image sensor, mobile terminal and image photographing method

Abstract

The invention provides an image sensor, a mobile terminal and an image photographing method. A pixel array of the image sensor comprises the preset number of pixel units. The pixel units comprise first pixels and second pixels which are in dual pixel focus. The first pixels comprise red, green and blue subpixels. The second pixels comprise at least one of the red and blue subpixels, the green subpixels and infrared subpixels. Locations of the infrared subpixels in the second pixels are the same as those of the red subpixels, green subpixels, blue subpixels, first combination of subpixels or second combination of subpixels in the first pixels. The first combination of subpixels are adjacent 1 / 2 red and green subpixels. The second combination of subpixels are adjacent 1 / 2 green and blue subpixels. Or the locations of the 1 / 2 infrared subpixels are the same as those of the 1 / 2 red subpixels, the 1 / 2 green subpixels or the 1 / 2 blue subpixels in the first pixels. The 1 / 2 infrared subpixelsin two adjacent second pixels form the infrared subpixels. According to the image sensor, the mobile terminal and the image photographing method, the rapid focus and background blurring can be carriedout, and three-dimensional photographing correlated application functions can be realized.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image sensor, a mobile terminal and an image capturing method. Background technique [0002] At present, smart electronic products have gradually become a necessity in people's lives, and the camera function, as an important configuration of electronic products, is also gradually developing. However, with the promotion and popularization of the camera function, people are no longer satisfied with the only camera function of the camera in the current smart electronic products, and are more expected to achieve diversified camera effects, diversified gameplay and diversified functions. [0003] Currently on the market, in the pixel array arrangement of image sensors based on CMOS (Complementary Metal Oxide Semiconductor, Complementary Metal Oxide Semiconductor), the most commonly used is the R (red) G (green) B (blue) Bayer pixel array arrangement mode ,Such as Figure ...
