Method and device for conducting mosaic processing on picture

Abstract

The embodiment of the invention discloses a method and device for conducting mosaic processing on a picture. The method includes the steps of establishing a memory graphic object corresponding to the to-be-shared picture, making a picture layer, corresponding to the to-be-shared picture, of picture layers corresponding to the memory graphic object transparent, copying the to-be-shared picture to the memory graphic object, selecting the to-be-processed mosaic area, separating the mosaic area into sub-areas according to the preset paintbrush granularity, calculating the average value of memory data in the memory graphic object in each sub-area and renewing the sub-area, redrawing each sub-area in the to-be-processed mosaic area into the to-be-shared picture according to the renewed memory data of the sub-area in the to-be-processed mosaic area so as to obtain a mosaic picture, loading a preset share control onto the mosaic picture, receiving sharing information triggered by a user through the share control on the mosaic picture, and sharing the mosaic picture to a user network share space chained by the share control. By means of the method and device for conducting mosaic processing on the picture, the picture processing efficiency can be improved.

Description

technical field [0001] The invention relates to graphics processing technology, in particular to a method and device for mosaic processing of pictures. Background technique [0002] With the continuous development of communication technology, the application of mobile communication devices, such as mobile phones, personal digital assistants, and mobile notebooks, is becoming more and more common. Take a picture, and share it with the network after taking a picture or taking a screenshot of the picture. [0003] Since the pictures (including the pictures taken by the user and the screenshots obtained after screenshot processing) may contain some content related to personal privacy, before sharing the picture on the Internet, the user needs to check the part of the content that contains personal privacy in the picture. Mosaic processing is to degrade the color scale details of a specific area in the picture that contains personal privacy, so as to cause the effect of color bl...

Problems solved by technology

[0015] It can be seen from the above that the existing methods for image mosaic processing need to call related functions for each pixel in the HDC area to be processed for mosaic processing, and the processing efficiency is low; further, image mosaic processing needs to switch between applications The program interface is cumbersome to operate and reduces the processing efficiency; moreover, in the process of mosaicing images, it is necessary to store intermediate processing images such as screenshots and mosaic images, which requires a large storage space
