Problems solved by technology

However, in the current image processing methods, the enhancement of the brightness of a pixel usually depends on the enhancement results of the previously enhanced pixels of the pixel, which undoubtedly makes the enhancement process of the image brightness occupy a large amount of image processing resources for a long time, such as precious CPU (central processing unit) resources
For example, in the field of video conferencing, most of the processing resources of the video conferencing system are used for such image processing tasks, which will greatly hinder the performance improvement of the video conferencing system

Abstract

An image processing method and an image processing device are described herein. The method includes determining a luminance value of the image. In response to the fact that the brightness value of theimage is smaller than an image brightness threshold value, the brightness of the image is enhanced, and which comprises: determining each pixel of the image as a to-be-enhanced pixel; determining a brightness enhancement value of the to-be-enhanced pixel based on the brightness value of the image, the initial brightness value of the to-be-enhanced pixel and the initial brightness value of the adjacent pixel of the to-be-enhanced pixel; and enhancing the brightness of the to-be-enhanced pixel so as to take the brightness enhancement value as an enhanced brightness value of the to-be-enhanced pixel. By utilizing the method and the device, the resource occupancy rate in the image processing process can be greatly reduced.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an image processing method and an image processing device. Background technique [0002] With the development of Internet technology, the requirements for image quality in all walks of life are getting higher and higher. For example, remote video conferencing, as the most important part of various functions of office collaboration products, has very high requirements on the quality of video images. If the environment where the user is located has unsatisfactory lighting conditions, the quality of the scene image in the video conference will be relatively poor. If the scene images in such an environment are not processed, the video conferencing experience will obviously be very poor. [0003] In order to present a high-quality image, it is usually necessary to enhance the brightness of the image. However, in the current image processing methods, the enhanc...
