Abstract

The invention discloses an image matrix memory overflow prevention processing method and system, and the method comprises the steps: carrying out the mapping conversion of a pixel matrix of an image,obtaining a first image, and converting the gray values of pixels of the first image to obtain a corrected image matrix; performing overflow prevention processing on a spatial domain of the correctedimage matrix to obtain a gray value sequence; forming an anti-overflow image by the gray value sequence and outputting the anti-overflow image to terminal equipment, so that the anti-overflow image can be quickly and effectively generated. By means of the image sub-block indexes, memory overflow can be avoided to the maximum extent, whether the image matrix causes memory overflow or not does not need to be recognized, overflow processing difficulty is low, processing speed is high, efficiency is high, and the method is suitable for terminal equipment which is small in memory ratio, low in configuration and not high in image definition requirement.

Description

technical field [0001] The present disclosure relates to the technical fields of file storage and image processing, and in particular to a processing method and system for preventing overflow of image matrix memory. Background technique [0002] When the pixels of the read pictures are very high and the image volume is relatively large, some devices with small memory, such as mobile devices, PDA industrial handheld terminals, smart POS, tablet computers and other devices, are often prone to image matrix failures. Overflow, which leads to the phenomenon of abnormal exit (flashback) of the application program, and in some other mainframe computing environments, the overflow of the image matrix is ​​a very common and very dangerous loophole, in various types of terminals It exists widely in operating systems and application software. The buffer overflow of the image matrix can lead to program interruption and exit, system downtime of terminal equipment and other consequences. ...
