Problems solved by technology

[0003] If the first method is used, when the current scene of the image requires a high bit rate to ensure the clarity of the scene, the fixed bit rate cannot reach the high bit rate, resulting in the fact that the scene requiring high definition is actually encoded as vague
If the second method is used, when the current image quality is very high, the current bandwidth of the device cannot meet the high bit rate required by the current high-quality image, resulting in insufficient performance of the device
If the third method is used, when the current scene of the image requires a high bit rate to ensure the clarity of the scene, because the current performance of the device cannot provide high bandwidth to ensure a high bit rate, it will also require a high-definition The scene is actually coded to be blurry
[0004] Therefore, the existing technology cannot ensure that the coded image meets the actual needs and that the performance of the device can meet the code rate requirements during the coding process.

Abstract

Embodiments of the present application provide an image encoding method and apparatus, which relate to the technical field of image processing. The method comprises: obtaining an image of a current frame; processing an image of the current frame to determine a current scene type of the image of the current frame; according to the current scene type, determining the current bit rate adapted to thecurrent scene type to encode the image of the current frame. As the current bit rate is adapted to the current scene type, that is, when the current scene type needs a high bit rate, the current bit rate correspond to a high bit rate, but when the current scene type does not need a high bit rate, the current bit rate corresponds to a low bit rate, so that the encoded image quality can meet the actual requirement. At that same time, since the bit rate can be adjusted between high and low according to the scene, the technical problem that the device performance is insufficient due to maintainingthe high bit rate all the time can be avoided, and the performance of the device can meet the requirement of the bit rate in the encoding process.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to an image encoding method and device. Background technique [0002] In the current coding technology, several kinds of coding can be adopted to code the image. The first way can be to use a fixed bit rate to encode the image, the second way can be to use the bit rate selected according to the image quality to encode the image, and the third way can be based on the bandwidth that the network environment can allow, using The code rate of the adaptive bandwidth encodes the image. [0003] If the first method is used, when the current scene of the image requires a high bit rate to ensure the clarity of the scene, the fixed bit rate cannot reach the high bit rate, resulting in the fact that the scene requiring high definition is actually encoded as Indistinct. If the second method is adopted, when the current image quality is very high, the current bandwidth ...
