Embodiment Construction

[0021] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, are only for explaining the embodiments of the present application, and should not be construed as limiting the embodiments of the present application.

[0022] In the related art, the color filter array in the camera is usually in the form of a Bayer array. However, in the color filter array arranged in the Bayer array, each color filter can only pass light of a single color. Part of the light will be filtered out, affecting the quality of the image captured by the camera.

[0023] For the above reasons, see figure 1 , figure 2 and Figure 5 , the present application provides a camera assembly 100 . The camera assembly 100 includes an ...

Abstract

The application discloses an image acquisition method, a camera assembly and a mobile terminal. The image acquisition method includes: exposing the pixel array to obtain a first color original image and a second color original image, the data of the first color original image is generated by at least one color photosensitive pixel in the subunit, and the data of the second color original image is generated by at least one of the subunits Generate a full-color light-sensitive pixel and at least one color light-sensitive pixel; interpolate the first color original image to obtain a first interpolated image of each color channel, and interpolate the second color original image to obtain a second interpolated image of at least one color channel; The interpolation image is fused with the first interpolation image of each color channel to obtain a fusion image of each color channel; the target image is obtained according to the fusion image of each color channel. In the embodiment of the present application, the first interpolation image and the second interpolation image are fused to improve the signal-to-noise ratio and definition of the image, thereby improving the quality of the image taken in a dark environment.

Description

technical field [0001] The present application relates to the field of image technology, and in particular to an image acquisition method, a camera assembly and a mobile terminal. Background technique [0002] Cameras can be installed in electronic equipment such as mobile phones so that the electronic equipment has an image acquisition function. The camera can be equipped with a color filter array to achieve color image acquisition. At present, the color filter array in the camera is usually in the form of a Bayer array. In the color filter array in the form of a Bayer array, each color filter can only pass light of a single color. Filter out, affect the quality of the image captured by the camera. Contents of the invention [0003] Embodiments of the present application provide an image acquisition method, a camera assembly, and a mobile terminal. [0004] The image acquisition method in the embodiment of the present application is used for an image sensor. The image...
