Embodiment 1

[0024] figure 1 It is a flowchart of a method for changing the green scene effect of an image in real time according to Embodiment 1 of the present invention. Such as figure 1 As shown, the method mainly includes the following steps:

[0025] Step 11. Calculate the difference between every two channels in the RGB channel of the current pixel in the image.

[0026] The difference between every two channels in the current pixel RGB channel in the calculation image includes:

[0027] Calculate the difference Diff_GR between the G channel and the R channel: Diff_GR=G-R;

[0028] Calculate the difference Diff_GB between the G channel and the B channel: Diff_GB=G-B;

[0029] Calculate the difference Diff_RB between the R channel and the B channel; Diff_RB=R-B.

[0030] Among them, the R, G, and B channels are respectively the red, green, and blue channels.

[0031] Step 12: Compare the calculated difference with a preset threshold to determine whether the current pixel needs g...

Abstract

The invention discloses a method for changing the green scene effect of an image in real time. The method comprises the steps of calculating the difference value of every two channels in red, green and blue (RGB) channels of the current pixel in the image; comparing the difference values obtained by calculation with a preset threshold value to judge whether green enhancement needs to be carried out on the current pixel or not; if yes, carrying out green enhancement on the current pixel according to the difference value obtained by calculation. After the method is adopted, the problem that a green object (especially a green plant) of the image is yellowish can be solved, the yellow green color is converted into jade green color, and the green in the image is brighter; furthermore, the method is small in calculation amount and rapid in speed.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for changing the green scene effect of an image in real time. Background technique [0002] With the continuous development of digital image processing technology of semiconductor chip technology, people can now easily obtain high-resolution video or pictures through digital cameras and mobile phones. However, due to the inherent hardware limitations of CMOS image sensors and the defects of ISP algorithms , so that the green objects (especially green plants) in the image are yellowish, green is a color that is more sensitive to the human eye, and the brightness of green directly affects people's visual experience, so it is particularly important to enhance the green component in the color. Contents of the invention [0003] The purpose of the present invention is to provide a method for changing the green scene effect of an image in real time, aiming to solve ...
