Embodiment Construction

[0065]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.

[0066] In practical applications, in office scenarios, it often happens that the user drags a window (software display box, text box, display box when the folder is open) from one position to another. In this case , the user often pays attention to whether the window is moved to the correct position, and does not care about the display content of the window during the moving process. B...

Abstract

The invention provides an image coding method and device, and relates to the technical field of computer images, and the method comprises the steps: collecting a current image frame; judging whether the current image frame comprises a window which moves relative to the previous image frame based on the dragging operation or not; and if the window moving based on mouse dragging relative to the previous frame is included, encoding the area where the moving window is located by adopting a first preset encoding mode. According to the method and the device, the problem of low coding efficiency of alow-code-rate mode for the moving window when the relative movement of the window generated based on mouse dragging is detected in the prior art can be solved.

Description

technical field [0001] The present disclosure relates to the technical field of computer images, in particular to an image encoding method and device. Background technique [0002] With the development of information technology, people's requirements for communication services are constantly increasing, and the contradiction between image communication and communication network capacity is becoming increasingly prominent. Image compression is the application of data compression technology to digital images, with the purpose of reducing redundant information in image data, so as to store and transmit data in a more efficient format. [0003] Traditional image coding algorithms mainly perform image compression from the two directions of inter-frame and intra-frame de-redundancy, but few people pay attention to the problem of visual redundancy. In the desktop scenario, a large number of desktop images need to be transmitted. Unlike natural images, desktop images have their ow...
