Image sensor, mobile terminal, and image shooting method

Abstract

The invention provides an image sensor, a mobile terminal, and an image shooting method. A pixel array of the image sensor comprises a preset number of pixel units, the pixel unit comprises full-pixeldual-core focusing first and second pixels, the first pixel comprises red, green and blue sub-pixels, the second pixel comprises at least one of red and blue sub-pixels, a green sub-pixel and an infrared sub-pixel, and the sub-pixels are arranged in a four-in-one manner; the infrared sub-pixel in the second pixel is located at the same location as the red, green, blue, first combined or second combined sub-pixels in the first pixel, and the first combined sub-pixel is an adjacent 1 / 2 red-green sub-pixel; the second combined sub-pixel is an adjacent 1 / 2 green-blue sub-pixel; or, the 1 / 2 infrared sub-pixel in the second pixel is located at the same location as the 1 / 2 red-green or blue sub-pixel in the first pixel, and the 1 / 2 infrared sub-pixels in two adjacent second pixels forms the infrared sub-pixel. The image sensor provided by the invention can realize fast focusing and background blurring, and improve the image imaging effect.

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 CMOS (Complementary Metal Oxide Semiconductor, Complementary Metal Oxide Semiconductor) image sensor pixel array arrangement, there is a commonly used four-dimensional sensor based on the improved R (red) G (green) B (blue) Bayer pattern. Unified p...
