Problems solved by technology

[0003] However, during the research and practice of the prior art, the inventors of the present invention found that since the installation package is relatively large, and the mobile terminal needs to save a large number of LUT material maps, it needs to occupy more network resources and storage resources. , which adversely affects the performance of the mobile terminal

Embodiment 1

[0068] This embodiment will be described from the perspective of an image processing device. Specifically, the image processing device may be integrated into a device such as a mobile terminal, and the mobile terminal may specifically be a device such as a mobile phone, a tablet computer, or a notebook computer.

[0069] An image processing method applied to a mobile terminal, comprising: acquiring an image to be processed and filter information selected by a user, determining whether a LUT filter corresponding to the filter information can be generated according to the filter information, and if so, generating The LUT material map corresponding to the filter information, generate the LUT filter corresponding to the filter information according to the LUT material map, and use the LUT filter to filter the image; if not, use the filter information corresponding to The filter for filters the image.

[0070] Such as Figure 1b As shown, the specific flow of the image processing ...

Embodiment 2

[0103] This embodiment will be described from the perspective of a network device for image processing, and the network device for image processing may specifically be integrated in a server or other device.

[0104] The embodiment of the present invention also provides another image processing method, which is applied to the server, including: acquiring a test image and filter information that needs to be processed; using a filter corresponding to the filter information to perform filter processing on the test image, Obtain a first processing result; generate a LUT filter corresponding to the filter information according to the filter information, and use the LUT filter to filter the test image to obtain a second processing result; determine the first processing result and Whether the difference between the second processing results is less than the set value, if so, then generate the discrimination information indicating that the LUT process can be performed on the filter inf...

Embodiment 3

[0130] According to the methods described in the previous embodiments, examples will be given below for further detailed description.

[0131] In this embodiment, description will be made by taking an example in which an image processing device is specifically integrated in a mobile terminal and a network device for image processing is specifically integrated in a server.

[0132] (1) First, the discrimination information of each filter information can be generated offline by the server, for example, see Figure 3a , the specific process can be as follows:

[0133] A301. The server acquires the test image and filter information that needs to be processed.

[0134] For example, it can specifically receive test images input by developers or operation and maintenance personnel, as well as filter information that needs to be processed.

[0135] Wherein, the format of the test image may include BMP, GIF, JPEG, TIFF, and RAW. The filter information refers to the information used ...

Abstract

The embodiment of the invention discloses an image processing method, apparatus and system, and a storage medium. According to the image processing method, apparatus and system disclosed by the embodiment of the invention, after an image to be processed and filter information selected by a user are obtained, whether a corresponding LUT filter can be generated can be determined according to the filter information, if so, a LUT material map corresponding to the filter information is generated, the LUT filter is generated according to the LUT material map, and the LUT filter is used for filteringthe image, and if not, the image is filtered by using a filter (i.e., a common filter) corresponding to the filter information. By adoption of the scheme, the network resources and the storage spaceare saved under the premise of implementing filter acceleration.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an image processing method, device, system and storage medium. Background technique [0002] In image processing, filter processing is a relatively common processing method. The implementation of filters is generally divided into two categories: code implementation and display lookup table (LUT, Look Up Table) implementation. Code implementation refers to realizing the filter effect through code description and calculation, while LUT implementation is to realize the filter effect through the look-up table (Look Up Table). Generally, a filter implemented by code can be called a common filter, or a filter for short, and a filter implemented by a LUT is called a LUT filter. Among them, the LUT filter can pre-calculate the result after filtering for each possible value range by enumerating the possible value ranges of red, green and blue (RGB, Red Green Blue) pixel v...
