Embodiment Construction

[0032] figure 1 It is a functional block diagram of an image encoding device according to an embodiment of the present invention. In this embodiment, the image encoding device 100 includes a buffer 110 and an image processing unit 120 . The image encoding device 100 is, for example, a smart phone (Smart Phone), a tablet computer (Tablet), a notebook computer, a personal digital assistant, or any other display screen that can be transmitted or shared to other image decoding devices (such as a set-top box ( Set-Top Box, STB)), to achieve screen mirroring (Mirracast) function of the electronic device. The wireless transmission technology is, for example, Wireless Fidelity direct (Wi-Fi direct), but possible embodiments of the present invention are not limited thereto. The buffer 110 is, for example, a storage medium such as a memory, which can store a plurality of frames associated with the image displayed by the mirror image encoding device 100 .

Abstract

Disclosed are an image coding method and an image coding device. The image coding method includes the following steps: collecting multiple frames enough for performing an H.264 coding mechanism in a buffer; dynamically switching coding rate of the H.264 coding mechanism according to at least one of using condition of the image coding device by a user and operating condition of an application program; adopting the H.264 coding mechanism corresponding to the coding rate to code the frames.

Description

technical field [0001] The present invention relates to an encoding method and an encoding device, and in particular to an image encoding method and an image encoding device. Background technique [0002] With the development of science and technology and the evolution of the times, people have paid more and more attention to the entertainment functions provided by electronic products. Therefore, various manufacturers are all scrambling to launch various novel digital entertainment products to attract consumers' attention. In order to allow users to project the images viewed on the mobile device to a display with a larger screen, an external device with a screen mirroring (Mirracast) function has been developed, which can be connected to the mobile device according to The image sent by the mobile device correspondingly controls the display (such as a TV) to display the same screen as the mobile device. [0003] Generally speaking, when the mobile device uses the H.264 enco...
