Problems solved by technology

If it is required to process the original image in real time and display the result immediately (that is, real-time preview), when the original image is large, the efficiency cannot meet the requirements of real-time preview due to the slow speed
Existing portable mobile devices usually have a camera function, but the real-time images obtained from the camera cannot achieve a time-sensitive effect preview based on the limitations of the existing technology

Abstract

The invention provides an image previewing device, which comprises an image display control unit, a display unit, an image acquisition unit, an image processing unit, an image data analyzing unit, an image rendering unit and an image synthesis unit, wherein the image processing unit carries out processing on a gray value of each pixel of the image content acquired by the image acquisition unit; the image data analyzing unit divides the acquired image data of each frame and sets the image data to be first texture data and second texture data; the image rendering unit carries out rendering with a special effect on the first texture data according to user requirements; and the image synthesis unit combines the rendered first texture data and the second texture data so as to generate an image with a predetermined format to display. The invention further provides an image previewing method. By using the device and the method provided by the invention, special-effect processing is carried out on the acquired image, and the image with the special effect is displayed at the same time, thereby realizing real-time previewing of image effects.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image preview device and method. Background technique [0002] In image processing technology, image editing and batch processing are the most basic and commonly used. At present, many image processing tools have the functions of single-image editing and multi-image batch processing. In the prior art, when editing an image, the image enters the editing and adjustment stage only after the editing parameters are selected, and icons and texts prompting the user to wait appear, and the final editing result is displayed after the user waits for a long time . If it is required to process the original image in real time and display the result immediately (that is, real-time preview), when the original image is large, the efficiency cannot meet the requirements of real-time preview due to the slow speed. Existing portable mobile devices usually have a camera functi...
