Problems solved by technology

At this time, if the MEMC function is executed on the data of the entire display screen, the screen fragmentation phenomenon will appear in the subtitle display area of ​​the movie. This is because the subtitle display area of ​​the movie is a still image, and the still image will appear fragmented under the MEMC function; If the MEMC function is not implemented for the data of the entire display screen, the display effect of the video image will not be good. This is because the MEMC function is not turned on for the video image displayed behind the subtitle display area of ​​the movie, so that it still has motion jitter and blur problems.

Embodiment 1

[0026] Based on the principles of the above invention, an embodiment of the present invention provides an image processing method, such as figure 1 As shown, the method includes:

[0027] S101. Acquire video data to be displayed.

[0028] Specifically, the video data to be displayed may include video data such as movies and televisions stored in the device in advance. It may also be that the acquired video stream data is downloaded in real time from the network device during playback. The present invention may not limit the storage format or storage method of the video data to be displayed.

[0029] S102. Acquire a static image corresponding to the video data to be displayed.

[0030] Specifically, the static images referred to in the embodiments of the present invention refer to various static images that need to be displayed simultaneously with the video data to be displayed. Specifically, the static image may include a subtitle pattern, a menu image, and the like.

Embodiment 2

[0060] After the image processing method provided by Embodiment 1 of the present invention is applied to a specific image processing apparatus, the embodiment of the present invention further provides a display device. Such as Figure 4 As shown, the display device 20 includes an image processing device 201 , a video player 202 , and an image processor 203 . The video player 202 can be a hardware device running third-party application software or other UI software, and the image processor 203 can be any chip for image processing, such as a frame rate conversion chip. The workflow of the display device 20 is as follows: Figure 5 shown, including:

[0061] S301. The image processing device 201 acquires video data to be displayed.

[0062] S302. The image processing device 201 determines whether the subtitle pattern is an embedded subtitle or an external subtitle.

[0063] If the subtitle pattern is an embedded subtitle, execute S303; if the subtitle pattern is an external s...

Embodiment 3

[0077] An embodiment of the present invention further provides an image processing device configured to execute the image processing method provided in Embodiment 1 above.

[0078] Such as Figure 8 As shown, the image processing device 40 includes: an acquisition unit 401 and a display unit 402 . in,

[0079] An acquisition unit 401, configured to acquire video data to be displayed and a static image corresponding to the video data to be displayed;

[0080] The display unit 402 is configured to display the static image in the first display area after the acquisition unit acquires the video data to be displayed and the static image corresponding to the video data to be displayed, and display the image corresponding to the motion-enhanced video data in the second display area; wherein , the motion enhanced video data is generated by performing MEMC processing on the video data for displaying images in the second display area in the video data to be displayed; the second displ...

Abstract

The embodiment of the invention provides an image processing method and device, and relates to the technical field of image processing. According to the embodiment of the invention, a static image andan image subjected to MEMC processing can be respectively displayed; and thus, influence of MEMC processing on display of the static image is avoided. The method comprises the steps of: obtaining video data to be displayed and the static image corresponding to the video data to be displayed; and, displaying the static image in a first display area, and displaying an image corresponding to motionenhancement video data in a second display area, wherein the motion enhancement video data is generated by MEMC processing on the video data in the video data to be displayed and used for displaying the image in the second display area; the second display area comprises the area in a display screen, except the first display area; and the first display area is the pre-set area in the display screen. The image processing method and device in the invention are applied to image processing and displaying.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing method and device. Background technique [0002] At present, in the image display industry, in order to eliminate problems such as motion jitter and motion blur existing in the image display process, a MEMC (Motion Estimate and Motion Compensation, Motion Estimation and Motion Compensation) function is introduced. The principle of the MEMC function is to insert a compensation frame between two traditional adjacent frames of images. Wherein, the interpolated compensation frame is generally a transition image between two or several frames of images generated by performing operations on the signals of two adjacent frames or several adjacent frames of images. Through this method of inserting transitional images between two traditional adjacent frames of images, the moving images can present a smoother visual effect, and the trajectory of objects in the dis...
