Embodiment Construction

[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] The present invention provides a pixel array of an embodiment, which includes a plurality of 4*4 matrix units arranged two-dimensionally, and the matrix unit includes photosensitive pixels 1, 2, 3, 4, and each photosensitive pixel is configured with a transparent One of green, red, and blue color filters, wherein in each matrix unit, a full light color filter can be selectively replaced part of the green color filter.

[0023] It can be seen from the above scheme that by selectively replacing part of the green color filter with the plenoptic color filter in each m...

Abstract

The invention provides a pixel array, a camera and an array-based color recovering method. The pixel array comprises multiple 4x4 Bayer matrix units in two-dimensional arrangement, wherein each matrix unit comprises a sensitization pixel; each sensitization pixel is provided with a color filter capable of permeating one of green, red and blue; and in each matrix unit, part green color filter is selectively substituted by a full gloss color filter. By the adopting pixel array, the camera and the array-based color processing method, the imaging quality of images can be improved, and the use is convenient.

Description

technical field [0001] The invention belongs to the field of digital image processing, in particular to a pixel array, a camera and a color processing method based on the array. Background technique [0002] In order to improve the imaging effect of images in dark environments, most cameras will consider the application of non-visible light (mainly infrared light). Currently known applications are mainly divided into two ways: [0003] 1. Single lens, one camera uses a double-pass or full-pass lens that can pass infrared light; [0004] This method can improve the image quality of the camera at night, but in ordinary scenes during the day, due to the intake of infrared light energy, the color will be distorted. For example: black cloth will become reddish. [0005] 2. Dual lenses, one camera is equipped with two types of lenses, when the light is strong (for example: during the day), the ordinary lens that only passes through visible light is used, and when the light is w...
