example 1

[0093] Example 1: Take the photosensitive unit that receives red light as an example. Such as Figure 8 As shown, the current pixel R 22 The color is red, associated with the pixel R 22 The color is also red, so R 22 =R 22 . current pixel Gr 23 The color green is associated with the pixel R 23 are not the same color, so the associated pixel unit G 1 , G 3 , G 5 and G 7 The pixel value of the current pixel Gr is obtained by interpolation 23 value, as shown in Equation 1.

[0094] Formula one:

[0095] current pixel Gb 32 The color green is associated with the pixel R 32 The colors of are not the same, according to the associated pixel unit G 1 , G 3 , G 5 and G 7 The pixel value of the current pixel Gb is obtained by the interpolation method shown in formula 2 32 pixel value.

[0096] Formula two:

[0097] current pixel B 33 The color of blue is associated with the pixel R 33 The colors are not the same, according to the associated pixel cell B 0 , B...

example 2

[0100] Example 2: Take the photosensitive unit receiving green light as an example. Such as Figure 9 As shown, the current pixel R 22 The color is red, with the associated pixel Gr 22 The colors of are different, according to the associated pixel unit R 3 and R 5 The pixel value of is restored by interpolation to obtain the current pixel R 22 The value of , as shown in Equation 4.

[0101] Formula four:

[0102] current pixel Gr 23 The color of green is associated with the pixel Gr 23 The same color, the value of the current pixel is the same as the value of the associated pixel, that is, Gr 23 =Gr 23 . current pixel Gb 32 The color of green is the same as the color of the associated pixel, and the value of the current pixel is the same as the value of the associated pixel, that is, Gr 32 =Gr 32 . current pixel B 33 The color of blue is associated with the pixel Gr 33 The color of the different, according to the associated pixel cell B1 , B 7 The pixel valu...

Abstract

The invention discloses an image sensor, an image processing method, an imaging device and a mobile terminal, wherein the image sensor includes: a photosensitive unit array, a filter unit array arranged on the photosensitive unit array, and a micro The lens array, wherein the photosensitive unit array includes a focused photosensitive unit and a non-focused photosensitive unit, and the image sensor has a first output mode and a second output mode. In the image sensor of the embodiment of the present invention, when the ambient light intensity of the photograph is less than the preset intensity, the image sensor generates an image in the first output mode, and when the ambient light intensity is greater than the preset intensity, generates the image in the second output mode. In addition, when the image sensor is used for focusing, phase focusing can also be performed according to the output values ​​of two parts of the photosensitive pixels in the focusing photosensitive unit, which can effectively improve the focusing speed. The invention also discloses an image processing method of the image sensor, an imaging device and a mobile terminal.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an image sensor, an image processing method, an imaging device and a mobile terminal. Background technique [0002] With the continuous updating of technology, more and more manufacturers have begun to use image sensors with 16M-4M structure. The image sensor outputs images in 4M mode under low-light conditions, which can improve the signal-to-noise ratio and noise performance. However, in low-light conditions, the 4M mode is slow to focus. Contents of the invention [0003] The object of the present invention is to solve one of the above-mentioned technical problems at least to a certain extent. [0004] In order to solve the above problems, the first aspect of the present invention proposes an image processing method for an image sensor, wherein the image sensor includes: a photosensitive unit array, a filter unit array arranged on the photosensitive unit array,...
