Embodiment Construction

[0088] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0089] The color correction module is an important part of the digital signal processing flow of digital imaging equipment. Its main function is to use a 3*3 color correction matrix to linearly transform the RGB color signals output by the image sensor, so that the RGB color signals originally related to the equipment The color signal is converted into a device-independent RGB standard color signal, thereby ensuring that the output image of the digital imaging ...

Abstract

The embodiment of the invention provides an imaging equipment color correction method and device, electronic equipment and a storage medium. The imaging equipment color correction method is applied tothe technical field of image processing, According to the imaging equipment color correction method, the parameters of the colors to be adjusted in the initial reference parameters are adjusted through the color fine adjustment parameters, so that the color deviation of each color can meet the preset deviation range. When the color deviation of each color meets a preset deviation range, determining that the color is different; taking the corresponding color correction matrix as a color correction matrix of the to-be-corrected digital imaging equipment; the color correction matrix of the to-be-corrected digital imaging device is used for correcting the color of the to-be-corrected digital imaging device, the situation that the color deviation of part of color blocks after correction is still large can be reduced, and the color correction effect of the digital imaging device can be enhanced.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a color correction method, device, electronic equipment and storage medium of an imaging device. Background technique [0002] As people's requirements for image display effects are getting higher and higher, image processing technology is also changing with each passing day, and image processing technology is applied in more and more fields, such as video surveillance, smart home, telemedicine, and film and television entertainment. Wait. For digital imaging devices, such as digital cameras, digital video cameras, and surveillance cameras, images are stored in the form of data, but the color of images in digital imaging devices is different from the color of real images perceived by human eyes. Color correction for digital imaging equipment. [0003] In related technologies, a 3*3 color correction matrix is ​​used to linearly transform RGB (Red Green Blue, red, green,...
