Embodiment Construction

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0021] An embodiment of the display method of the ultra-high resolution image of the present invention, such as figure 1 shown, including the following steps:

[0022] Step S101: at the signal source server, send the super-large resolution image to the processor receiving client.

[0023] Step S102: determine the size of the resolution of the signal source at the image display client, marked as MxN

[0024] Step S103: Obtain the maximum unit resolution value that can be displayed by the graphics card, marked as mxn. Compare the size of these two resolutions, and c...

Abstract

The invention discloses a method and system for displaying ultrahigh resolution images. After the ultrahigh resolution images are received, image data are stored into texture data by using a Direct3d display technology rather than carrying out CPU decoding directly, the color value of each pixel is obtained in a rasterizer stage of a graphic plotting pipeline, and the decoding process of the texture data is completed according to the guidance of an encryption algorithm. The advantage that GPU floating-point calculation capacity is strong is fully utilized in the decoding process, the decoding speed is improved greatly, the display frame rate can be improved obviously, and the ultrahigh resolution images greatly meet the urgent needs of people for searching huge amounts of image data under high-definition display media.

Description

technical field [0001] The invention relates to the technical field of image display, in particular to a method and system for displaying ultra-high resolution images. Background technique [0002] The ultra-high resolution signal image (26kx4k) cannot be displayed in one image due to the limitation of the display capability of the graphics card. If the traditional GDI method is used for drawing, for such an ultra-high resolution image, without hardware acceleration, the frame rate of image display is very low, and the synchronization is very poor. There are some other methods, by dividing the image at the data sending end, and then transmitting each divided sub-image with a corresponding number of hardware channels. If this method is aimed at ultra-high resolution images of 26kx4k, many hardware channels will be added. , will greatly increase the hardware cost. Therefore, it is only suitable for the display of smaller resolution images, such as 4kx2k. [0003] To sum up,...
