Image translation update display method and system

Abstract

A method and system for updating and displaying an image, the method comprising the steps of: acquiring public image data from a first memory and copying it to a second memory when the image is being updated in translation; wherein, the first memory is used to save complete image data, the public image data is the image data of the same area before and after the image translation update in the first memory; the changed image data is drawn into the third memory; wherein, the changed image data is the image data of the changed area before and after the image translation update in the first memory Image data; copying the image data in the second internal memory and the third internal memory to the first internal memory; displaying the image data in the first internal memory. The calculation of the present invention can effectively reduce the amount of data to be processed for each translation operation, increase the speed of the translation operation, and improve the display efficiency of the map translation.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image translation update display method and system. Background technique [0002] When displaying images in traditional technologies, the rendering system generally obtains the image data to be displayed according to the display range of the display device, then draws the image data on a memory, and then outputs it to the display device for display. When the image is translated and updated, according to the recalculated display range, the image data after the translation and update is found, the image data is drawn on the memory, and then displayed. [0003] In the above technology, each time the image is translated and updated, the image within the display range of the entire display device needs to be drawn once, but in fact, when most images are translated and updated, many parts of the image data are the same before and after the update , which causes a l...

Problems solved by technology

[0003] In the above technology, each time the image is translated and updated, the image within the display range of the entire display device needs to be drawn once, but in fact, when most images are translated and updated, many parts of the image data are the same before and after the update , which causes a large number of repeated drawing processes, resulting in a serious waste of processor resources, especially when the resolution of the display device is large, the amount of image data redrawn each time is very huge, reducing the speed of translation operations, and even causing screen freezes Phenomenon
