Problems solved by technology

However, few video processing devices currently support YUV420 format input sources. In addition, individual video processing devices that support YUV420 format input sources do not restore image information very well, resulting in serious loss of image information.

Abstract

Embodiments of the present invention provide an image processing method, an image processing device, an image processing system, and a computer-readable medium, for example, the image processing method includes: receiving odd-numbered line image data in a first color coding format; Cache the odd-numbered line image data in the first color-coding format; receive the even-numbered line image data in the first color-coding format; performing format conversion on the image data to obtain odd-numbered line image data in a second color-coded format and even-numbered line image data in a second color-coded format; outputting odd-numbered line image data in the second color-coded format; and buffering the second color-coded format Even lines of image data. The image processing method proposed by the embodiment of the present invention can enable the video processing device to support the input of the video source in the YUV420 format, thereby improving the compatibility of the device.

Description

technical field [0001] The present invention relates to the technical field of image processing and display, and in particular, to an image processing method, an image processing apparatus, an image processing system and a computer-readable medium. Background technique [0002] In video processing equipment, the compatibility and processing capability of its input interface are very important. It is often required that the input interface can support video source input in multiple image data formats, such as RGB or YUV. Among them, YUV is a color coding method that separates luminance information (Y) and chrominance information (UV). Since the human eye is mainly sensitive to luminance information, the bandwidth can be further reduced by sampling the U and V components. YUV usually includes three color coding formats: YUV444, YUV422 and YUV420. Among them, YUV420 can use relatively small bandwidth to transmit image information of the same size, reducing bandwidth consumpti...
