Problems solved by technology

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

[0034] see figure 1 , the first embodiment of the present invention provides an image processing method. Such as figure 1 As shown, the image processing method includes steps S11-S16, for example.

[0035] Step S11: receiving odd-numbered row image data in the first color-coding format;

[0036] Step S12: Buffering the odd-numbered row image data in the first color-coding format;

[0037] Step S13: Receive even-numbered row image data in the first color-coded format;

[0038] Step S14: Perform format conversion on the cached odd-numbered line image data in the first color-coding format and the received even-numbered line image data in the first color-coding format to obtain odd-numbered line image data in the second color-coding format and the second color Encoding format even row image data;

[0039] Step S15: Outputting the odd-numbered row image data in the second color-coding format; and

[0040] Step S16: Buffering the image data of even lines in the second color co...

[0054] see Figure 7 , the second embodiment of the present invention provides an image processing device. Such as Figure 7 As shown, the image processing device 30 includes, for example: a receiving module 31, a buffer module 32, a receiving module 33, a format conversion module 34, an output module 35 and a buffer module 36.

[0055] Wherein, the receiving module 31 is used for receiving the image data of odd lines in the first color coding format. The buffering module 32 is used for buffering the image data of odd lines in the first color coding format. The receiving module 33 is used for receiving even line image data in the first color coding format. The format conversion module 34 is configured to perform format conversion on the cached odd-numbered line image data in the first color-coding format and the received even-numbered line image data in the first color-coding format, so as to obtain the second color-coding format odd-numbered line image data and The second...

[0063] see Figure 8 , the third embodiment of the present invention provides an image processing system. Such as Figure 8 As shown, the image processing system 50 includes, for example: a processor 51 and a memory 52 connected to the processor 51. The memory 52 stores instructions executed by the processor 51, and the instructions cause the processor 51 to perform operations to perform the image processing method as described in the first embodiment. For example, the processor 51 performs the following operations:

[0064] (i) receiving first color-coded format odd row image data;

[0065](ii) cache the first color-coded format odd-numbered row image data;

[0066] (iii) receiving the first color-coded format even row image data;

[0067] (iv) Perform format conversion on the buffered first color-coded format odd-numbered line image data and the received first color-coded format even-numbered line image data to obtain the second color-coded format odd-numbered line imag...

Abstract

An embodiment of the invention provides an image processing method, an image processing device, an image processing system and a computer readable medium. The image processing method comprises the following steps of: receiving odd-numbered row image data in a first color coding format; caching the odd-numbered row image data in the first color coding format; receiving even-numbered row image datain the first color coding format; performing format conversion on the cached odd-numbered row image data in the first color coding format and the received even-numbered row image data in the first color coding format to obtain odd-numbered row image data in a second color coding format and even-numbered row image data in the second color coding format; outputting the odd-numbered row image data inthe second color coding format; and caching the even-numbered row image data in the second color coding format. According to the image processing method provided by the embodiment of the invention, the video processing equipment can support YUV420 format video source input, and the compatibility of the equipment is improved.

Description

technical field [0001] The present invention relates to the field of image processing and display technologies, and in particular to an image processing method, an image processing device, 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) from 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 a relatively small bandwidth to transmit image information of the same size, reducing bandwidth consum...
