Problems solved by technology

In general, the stretched image looks higher in contrast. However, for graphics cards that need to be stretched, they will still be stretched after receiving YUV image data in the range [0, 255] processing, resulting in the loss of the darkest and brightest parts of the output displayed image, reducing the display effect of the image
[0004] To sum up, the existing technology does not adaptively adjust the image according to the relevant parameters of the image display device, resulting in distortion of the output displayed image and reducing the display effect of the image

Embodiment Construction

[0022] An embodiment of the present invention provides an image processing method, an image capture chip, a camera, and a communication system, which are used to realize the adaptive matching between the image and the image display device, thereby improving the display effect of the image and avoiding display errors. The image is distorted.

[0023] In the embodiment of the present invention, the parameters related to the image display of the local image display device or the remote image display device are first obtained; and according to these parameters, the image is preprocessed so that the output image and the image display device achieve the best match Effect.

[0024] The technical solutions provided by the embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0025] see figure 1 , a kind of image processing method that the embodiment of the present invention provides comprises the steps:

[0026] S101. Acquire ...

Abstract

The invention discloses an image processing method, an image processing device and an image processing system used for realizing the self-adaption matching of an image and an image display device so as to improve the display effect of the image and avoid displayed image distortion. The image processing method provided by the invention comprises the following steps: obtaining configuration parameter information of the image display device; preprocessing the image acquired by an image acquiring device according to the configuration parameter information of the image display device, wherein the configuration parameter information of the image display device includes the information of whether the image needs to be processed on brightness or chromaticity range expansion by a display card or not and / or red, green and blue (RGB) color mode information supported by a display screen; and sending the preprocessed image to the image display device.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device and system. Background technique [0002] The USB cameras usually used in computers work according to some parameters set before leaving the factory. In some cases, even if there are some parameters related to image display processing on the connected computer that do not match the camera, the camera will not automatically adjust accordingly. [0003] For example, the graphics card related to image display processing in some computers is an integrated graphics card, and some graphics cards are discrete graphics cards. Each graphics card manufacturer may adopt different parameters when designing a graphics card. For example, after receiving the luminance component in the range of [16, 235] and the chrominance component (YUV) data in the range of [16, 240], some graphics cards actually display them on the screen as they are, tha...
