Abstract
A fuzzy processing method of all-liquid crystal instrument frosted glass relates to a frosted glass fuzzy technology and aims to solve the problem that the temperature of a CPU is rapidly increased due to the fact that the real-time frosted glass background effect occupies large resources in the existing frosted glass processing. The fuzzy processing method of the all-liquid crystal instrument frosted glass is realized by the following steps: step one, capturing an image of a designated area; step two, calculating a change area in the designated area image; and thirdly, rendering the image of the appointed area. The beneficial effects are that more than 70% of resources can be saved; and simultaneously, unnecessary repeated operation of the GPU is reduced.
Description
Technical Field
The invention relates to a ground glass blurring technology.
Background
As most of all liquid crystal instruments of the existing products adopt Linux platforms, when the interface of the all liquid crystal instruments needs to be displayed in a pop-up mode, pop-up frames are often overlapped with the background of a base map, so that the content displayed by the pop-up frames cannot be seen clearly, if the pop-up frames are made into opaque pop-up frames, the overall effect is greatly reduced, and when the pop-up frames are arranged at the lower layer, a ground glass effect is added at the upper layer of the background, namely the recognition degree of the pop-up frames is increased, and the detail effect is also increased for the pop-up frames; because the pop-up box is a designated area and the designated area is a change content, a fixed ground glass background picture cannot be made, at the moment, the area effect of the current interface of the all-liquid crystal instrument needs to be grasped through a software technology and ground glass processing is made, but the real-time ground glass background effect occupies very large resources and can cause the rapid rise of the temperature of a CPU, so the ground glass background effect becomes a bottleneck in the industry.
Disclosure of Invention
The invention aims to solve the problems that in the existing frosted glass treatment, the real-time frosted glass background effect occupies large resources, and the temperature of a CPU rises rapidly; a fuzzy processing method for frosted glass of full-liquid crystal instrument is disclosed.
The fuzzy processing method of the all-liquid crystal instrument frosted glass is realized by the following steps:
step one, capturing an image of a designated area;
step two, calculating a change area in the designated area image;
and thirdly, rendering the image of the appointed area.
Further, the specific steps of grabbing the designated area in the first step are as follows:
step one, first identifying the appointed area;
reading the left lower corner coordinates of the designated area and the length and width of the designated area;
step one, obtaining image information of the area;
step three, the CPU calculates the blurring effect of the area for the first time;
and step four, the result of the first operation of the CPU is displayed by the GPU for the first time.
Further, the specific step of calculating the change region in the specified region image in the second step is as follows:
step two, identifying the appointed area again;
the designated area is the same as the designated area identified for the first time in the step one;
step two, 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 the second step and the third step;
step two, grabbing a change area;
extracting position coordinates of a change area in the designated area and image content through program operation;
step two, performing ground glass fuzzy operation on the change area in the CPU;
fifthly, fusing the changed area and the unchanged area in the designated area;
and step two, displaying the fused appointed area again by the GPU.
Further, the specific method for rendering the image of the specified area in the third step comprises the following steps: and reading out data transmitted by the CPU, analyzing out a blurred image of ground glass, rendering the image and placing the image between the bottom layer and the pop-up alarm layer.
The invention has the advantages that by judging the area of the real-time changing image content, under the same condition, a great amount of repeated operation of the CPU is reduced, so that the CPU has less heating value, the aging degree of the CPU is reduced, the CPU operates which areas in the designated area are changed, and the frosted glass blurring is only carried out on the changed areas, thereby saving more than 70% of resources during real-time rendering processing; meanwhile, unnecessary repeated operation of the GPU is reduced, and sufficient space is reserved for CPU resources by judging the area of the image content which changes in real time, so that the method is convenient to be applied to other technical fields.
