Embodiment Construction

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. For convenience of description, the sizes of different layers and regions are enlarged or reduced, so the sizes and ratios shown in the drawings do not necessarily represent actual sizes, nor do they reflect the proportional relationship of sizes.

[0040] figure 2 A structural schematic diagram of a color filter array provided for an embodiment of the present invention, such as figure 2 As shown, it includes: color filter unit 1 and colorless filter unit 2.

[0041] Wherein, the color filter unit 1 comprises at least three primary color color filters arranged adjacently, and the primary color color filter is a red (R) color filter, a green (G) color filter o...

Abstract

The invention provides a color filter array and an image processing method. The color filter array comprises color filter units and a color-free filter unit, wherein the color filter units comprise at least three primary color filters which are distributed adjacently, and each color filter unit comprises a red color filter, a green color filter and a blue color filter; and the color-free filter unit comprises color-free color filters which are distributed on the periphery of the color filter units. Because the color-free color filters allow all colors of light to transmit, light rays can be directly irradiated on an image sensor by virtue of the color-free color filters so as to ensure that the light-sensing performance can be improved. In addition, when image processing is performed, a color channel of colored images obtained by virtue of imaging performed by the color filter units in the color filter array and a brightness channel of gray level images obtained by virtue of imaging performed by the color-free filter unit in the color filter array are fused to obtain a required image, and thus the light-sensing performance and resolution degree of an imaging system can be further improved.

Description

technical field [0001] The invention relates to image processing technology, in particular to a color filter array and an image processing method. Background technique [0002] The color filter is one of the components in the imaging system, which is arranged in front of the image sensor to allow light of a single color to pass through and be captured by the image sensor. As a common color filter array, the Bayer array, figure 1 is a schematic diagram of a Bayer array, such as figure 1 shown, as an example, in figure 1 Among them is a 4×4 array, and the Bayer array is composed of 8 green filters, 4 blue filters and 4 red filters, and each filter corresponds to a photosensitive unit in the image sensor, that is, a pixel. After the light passes through a color filter with a specific color, it is captured by the photosensitive unit in the image sensor, and the pixel value measured by the photosensitive unit can represent the light intensity of the specific color, that is, co...
