Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] Embodiments of the present invention provide a system architecture for image processing, such as figure 1As shown, the image to be processed is input to the block unit in the image processing system. A variety of block rules can be set in the block unit, so that the block unit determines the first block rule corresponding to the image to be processed according to the image information of the image to be processed, and performs th...

Abstract

The embodiment of the invention provides an image processing method and device, and the method comprises the steps: determining each target image block from a to-be-processed image, and enabling an image in at least one target image block to be a color image; determining an image correction coefficient of the to-be-processed image according to the brightness correction value of each target image block; and correcting the to-be-processed image according to the image correction coefficient. According to the method, compared with the prior art in which single analysis and correction are carried out only through color temperature or brightness, perception differences of human eyes on images and videos and image jump of the images and the videos can be further eliminated, and the visual effect of color migration is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image processing method and device. Background technique [0002] With the improvement of network speed, more and more visual files such as images and videos appear in our lives. For example, video capture of monitoring system, video capture and image capture of photography, etc. However, the collected videos and images generally need to be rectified. On the one hand: due to the logarithmic nonlinearity of the human eye's response to brightness, and the different sensitivity of the human eye to different light waves; therefore, the human eye's perception of color and brightness is different from the color and brightness of the physical world. Therefore, in terms of collecting video and images, it is often necessary to correct the video and images captured by the camera to provide better visual effects. On the one hand: a sudden change in the acquisiti...
