Image sensor, mobile terminal, and image shooting method

Abstract

The invention provides an image sensor, a mobile terminal, and an image shooting method. The image sensor comprises a pixel array, the pixel array comprises a preset number of pixel units arranged ina predetermined manner, the pixel unit comprises a first pixel and a second pixel adjacent to the location of the first pixel, the first pixel comprises a red sub-pixel, a green sub-pixel and a blue sub-pixel, the second pixel comprises a red sub-pixel, a green sub-pixel and an infrared sub-pixel, both of the first pixel and the second pixel are full-pixel dual-core focusing pixels, and the sub-pixels in the first pixel and the second pixel are arranged in a four-in-one manner; and the location of the infrared sub-pixel in the second pixel is the same as the location of the blue sub-pixel in the first pixel. The image sensor provided by the invention can realize fast focusing and background blurring, enhance image imaging effect, realize relevant application functions of stereo photography, and ensure the functional diversification of the mobile terminal while ensuring the shooting experience.

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...
