Abstract
A fuzzy processing method for all liquid crystal instrument ground glass relates to a ground glass fuzzy technology, and aims to solve the problem that the real-time ground glass background effect occupies large resources in the existing ground glass processing, which causes the temperature of a CPU to rise rapidly.

The beneficial effects are that more than 70% of resources can be saved; and unnecessary repeated operation of the GPU is reduced.
Description
Technical Field
The invention relates to a fuzzy technology of ground glass.
Background
The Linux platform is mostly adopted for all liquid crystal instruments of the existing products, when the interfaces of all liquid crystal instruments need pop-up display, the pop-up frame often coincides with the background of the base image, so that the content displayed by the pop-up frame cannot be clearly seen, if the pop-up frame is made to be opaque, the overall effect can be greatly reduced, and at the time, a layer of frosted glass effect is added on the upper layer of the background on the lower layer of the pop-up frame, so that the recognition degree of the pop-up frame can be increased, and the detail effect can also be added for the pop-up frame; because the pop-up box is a designated area and the designated area is changed, a fixed ground glass background picture cannot be made, at this time, the area effect of the current interface of the full liquid crystal instrument needs to be captured by a software technology and ground glass processing is performed, but the real-time ground glass background effect occupies a large amount of resources and causes the temperature of a CPU to rise rapidly, so that the ground glass background effect becomes a bottleneck in the industry.
Disclosure of Invention
The invention aims to solve the problem that the real-time ground glass background effect occupies large resources in the existing ground glass treatment, which causes the temperature of a CPU to rise rapidly; a fuzzy processing method for full liquid crystal instrument ground glass is provided.
The fuzzy processing method of the full liquid crystal instrument ground glass is realized by the following steps:
firstly, capturing an image of a designated area;
step two, calculating a change area in the designated area image;
and step three, rendering the image of the designated area.
Further, the specific steps of capturing the designated area in the step one are as follows:
firstly, identifying a designated area;
reading the lower left corner coordinate of the designated area and the length and width of the designated area;
step two, acquiring image information of the area;
step three, the CPU calculates the fuzzy effect of the area for the first time;
and step four, displaying the result of the first operation of the CPU by the GPU for the first time.
Further, the specific step of calculating the change area in the image of the designated area in the step two is as follows:
step two, identifying the designated area again;
the designated area is the same as the designated area identified for the first time in the step one;
secondly, judging an image change area; if the designated area has no image change, ending the operation; if the designated area has a change area, executing a third step;
step two, grabbing a change area;
extracting the position coordinates and the image content of the change area in the designated area through program operation;
fourthly, fuzzy operation of the ground glass is carried out on the change area in the CPU;
step two, fusing the changed area and the unchanged area in the designated area;
and step two, displaying the fused designated area again by the GPU.
Further, the specific method for rendering the image of the designated area in the third step is as follows: and reading data transmitted by the CPU, analyzing a fuzzy image of the ground glass, rendering the image and placing the image between the bottom layer and the pop-up alarm level.
The method has the advantages that through the judgment of the regions of the real-time changing image content, under the same condition, a large amount of repeated operation of the CPU is reduced, so that the CPU has less heat productivity, the aging degree of the CPU is reduced, which regions in the specified region are changed through the operation of the CPU, and the fuzzy glass is only carried out on the changed regions, so that more than 70% of resources can be saved during real-time rendering; meanwhile, unnecessary repeated operation of the GPU is reduced, sufficient space is reserved for CPU resources by judging the area of real-time changing image content, and more applications are facilitated in other technical fields.
