Abstract

The invention discloses a method and a device for transmitting image data from a driving layer to an application layer. The method includes the steps: triggering the driving layer by the aid of a screenshot instruction to capture an image; dividing the image into a plurality of image areas; starting one transmission thread according to each image area; parallelly transmitting image data and position information of each image area to the application layer from the driving layer by the aid of the transmission thread, receiving the image data of each image area by the application layer, and storing the image data corresponding to the image areas according to the position information. According to the method, the screenshot instruction triggers the driving layer to capture the image, the image is divided into a plurality of image areas, the transmission threads of corresponding quantity are started, the image data of the image areas are transmitted to the application layer, so that a mode of multi-thread parallel transmission solves the problem that the transmission speed of an image acquired by screenshot is low from the driving layer, so that screenshot efficiency is effectively improved, and time consumed by screenshot is shortened.

Description

technical field [0001] The invention relates to the field of data transmission processing, in particular to a method and device for image data transmission between a driver layer and an application layer, a terminal, and a computer-readable storage medium. Background technique [0002] With the advancement of technology, in order to provide more friendly interactions for smart devices, users use the screenshot function of smart devices more and more frequently. Among them, smart devices include smart TVs, smart watches, smart phones, tablets, etc. . For example, during the use of smart devices, when switching applications, thumbnails in some applications, and interactive operations between smart devices (for example: screen transfer operations), the screenshot function is often used. Application scenarios have very high requirements on the speed of taking screenshots on smart devices. [0003] Usually, there are many factors that affect the speed of screenshots, such as th...
