Embodiment Construction

[0052] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0053] Such as figure 1 Shown is a schematic diagram of the architecture of the embodiment of the disclosure, wherein the target data refers to the original image data to be encoded output from the graphics card, and the encoder is used to encode the image according to the image encoding algorithm. In the embodiment of the disclosure, the image encoding There are no restrictions on th...

Abstract

The invention provides an image processing method and device, relates to the technical field of image processing, and solves the problem that image quality cannot be balanced while high compression rate is pursued in the prior art. According to the specific technical scheme, the image processing method comprises the steps: acquiring a current available bandwidth B and calculating a bandwidth Bi required for encoding transmission of a target image under a preset image encoding quality level; and determining a current most suitable image coding quality grade according to whether Bi is greater than B and different limiting conditions, and coding the target image based on the quantization parameter of the grade, thereby solving the problem that the image quality cannot be balanced while pursuing a high compression rate in the prior art.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to an image processing method and device. Background technique [0002] With the rapid development of Internet technology, the digital information age has penetrated into all aspects of people's lives, and the network transmission of images and videos is becoming more and more common in Internet applications. On the public network, due to bandwidth and delay issues, it is still very difficult to realize real-time transmission of images and videos. [0003] The current technology mainly uses the redundancy of image information to pursue a high compression rate according to the current application scenario to reduce the bandwidth required for transmission in the network. For example, the image compression standards of JQEG and JQEG2000 are more suitable for static images, that is, continuous Hue (including grayscale and color) still image compression coding; H2...
