Method and device for storing image in texture memory

Abstract

The embodiment of the invention discloses a method and a device for storing an image in a texture memory. The method comprises the following steps of: obtaining the dimension information of an image; on the basis of the dimension information of the image, determining a texture memory dimension corresponding to the image; and on the basis of the texture memory dimension, segmenting the image to obtain a plurality of image blocks, and storing the plurality of image blocks obtained by segmentation in the texture memory according to a preset storage rule. By use of the method and the device, which are provided by the embodiment of the invention, for storing the image in the texture memory, the memory can be saved, and image processing speed is improved.

Description

technical field [0001] The present application relates to the technical field of computer information processing, in particular to a method and device for storing images in a texture memory. Background technique [0002] With the development of computer technology, the application of image processing is more and more extensive. In the process of image processing, it is usually necessary to apply for a piece of texture memory for the image, and store the picture in the texture memory for image processing. For computer graphics cards, if the width and height of the image texture are powers of 2, the processing speed of the image will be faster. [0003] The existing method for storing an image in a texture memory usually includes: applying for a piece of texture memory for the image, the width of the texture memory is greater than or equal to the original width of the image and is a power of 2, and the height of the texture memory is greater than or equal to the image The or...

Problems solved by technology

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in the prior art: in the existing method of storing images in the texture memory, the size of the texture memory is in accordance with the power of 2 greater than or equal to the height or width of the image , in some cases, for example, for an image with a size of 65 pixels x 65 pixels, in order to meet the requirement that the width and height of the image texture be a power of 2, the size of the texture is 128 pixels x 128 pixels, and the size of the texture memory is larger than the size of the actual image A lot, so existing methods of storing images in texture memory can waste a lot of memory, and also slow down image processing
