Problems solved by technology

That is to say, in the existing technology, for different hardware modules, different scenes and different images, repeated parameter debugging is required, and the debugging results depend on the subjective feelings of the staff. Therefore, the existing color management methods often have debugging efficiency. Low, poor intelligence, unstable debugging effect

Embodiment Construction

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the specific embodiments described here are only used to explain the related application, not to limit the application. It should also be noted that, for the convenience of description, only the parts related to the relevant application are shown in the drawings.

[0038] The main function of the image signal processing ISP is to post-process the signal output by the front-end image sensor. The details of the scene can be well restored under all conditions, and the ISP technology largely determines the imaging quality of the camera. It can be divided into two forms: independent and integrated. .

[0039] ISP firmware (Firmware) mainly includes three parts, one part is ISP control unit and basic algorithm library, the other part is automatic expo...

Abstract

The embodiment of the invention discloses a color management method and device, a terminal and a storage medium, the color management method is applied to the color management device, and the color management method comprises the following steps: establishing a color database, and generating an effect database corresponding to the color database; obtaining a spectral response parameter corresponding to a shooting device of the terminal; based on the spectral response parameters, the color database and the effect database, generating a corresponding relationship between the scene and the parameters; and transmitting the corresponding relationship between the scene and the parameter to the terminal, so that the terminal realizes color management according to the corresponding relationship between the scene and the parameter.

Description

technical field [0001] The embodiments of the present application relate to the technical field of electronic equipment, and in particular, to a color management method and equipment, a terminal, and a storage medium. Background technique [0002] Image Signal Processing (ISP), the main function is to post-process the signal output by the front-end image sensor. The main functions include linear correction, noise removal, dead point removal, interpolation, white balance, automatic exposure control, etc., relying on Only ISP can better restore scene details under different optical conditions, and ISP technology determines the imaging quality of the camera to a large extent. [0003] At present, when performing color management through the ISP, it is mainly manual debugging. For example, the debugging engineer uses the ISP debugging tool to repeatedly debug the parameters in the ISP to achieve the desired output effect. That is to say, in the existing technology, for differen...
