Embodiment 1

[0048] In the embodiment of the present invention, in order to convert the video image into a reconstructed video image that matches the aspect ratio of the display screen at the receiving end, the sending end needs to first divide the original video image into multiple sub-images, and then the receiving end divides the multiple sub-images into sub-images. The images are combined to obtain a recombined video image with the same aspect ratio as the display screen itself.

[0049] Wherein, when the sending end divides the original video image, it can divide according to the preset division strategy corresponding to the aspect ratio of the display screen of the receiving end; Combination strategy to combine multiple sub-images. In this embodiment 1, the specific division strategy and combination strategy are described in detail, as follows:

[0050] The first way: if image 3 Shown is a relatively simple division method, wherein the original video image is divided into three su...

Embodiment 2

[0058] In Embodiment 2 of the present invention, the method for processing video images using the above-mentioned division and combination of video images is described in detail, and its flow chart is as follows Figure 8 As shown, it specifically includes the following processing steps:

[0059] Step S801 , the sending end and the receiving end obtain attribute information of the display screen of the receiving end through information interaction, for example, obtain the aspect ratio of the display screen of the receiving end.

[0060] Step S802, for the original video image currently to be transmitted, the sending end divides the original video image into multiple sub-images according to a preset division strategy corresponding to the aspect ratio of the display screen of the receiving end. The specific division strategy can adopt the various manners described in Embodiment 1 above, which will not be described in detail here.

[0061] For the current original video image to...

Embodiment 3

[0079] Based on the same inventive concept, according to the video image processing method provided by the above-mentioned embodiments of the present invention, correspondingly, Embodiment 3 of the present invention also provides a video image processing device, which can be integrated at the sending end, and its structural diagram is as follows Figure 9 shown, including:

[0080] A division unit 901, configured to divide the original video image into a plurality of sub-images according to a division strategy corresponding to the aspect ratio of the display screen at the receiving end;

[0081] The sending unit 902 is configured to send the divided sub-images and combination strategy information corresponding to the aspect ratio of the display screen of the receiving end to the receiving end, the combination strategy information is used to indicate that the receiving end According to the combination strategy represented by the combination strategy information, combine the mul...

Abstract

The invention discloses a method, a device and a system for processing video images. The method includes that a transmitting end divides an original video image into a plurality of sub-images according to a dividing strategy corresponding to an aspect ratio of a display screen of a receiving end; the divided multiple sub-images and combination strategy information corresponding to the aspect ratio of the display screen of the receiving end are transmitted to the receiving end; the receiving end receives the multiple sub-images transmitted by the receiving end and the combination strategy information corresponding to the aspect ratio of the display screen of the receiving end; the multiple sub-images are combined into a recombined video image with an aspect ratio identical to the aspect ratio of the display screen of the receiving end according to a combination strategy represented by the combination strategy information; and the recombined video image is displayed on the display screen. According to the scheme provided in an embodiment of the invention, the method, the device and the system have the advantage that the video image displayed at the receiving end is matched with the display screen when an aspect ratio of the transmitting end of the video image is inconsistent with the aspect ratio of the display screen of the receiving end.

Description

technical field [0001] The present invention relates to the technical field of video extension in the field of communication technology, in particular to a video image processing method, device and system. Background technique [0002] The video expansion technology is to transmit the video content on the terminal device to other display devices for display and playback according to the original proportion. At present, video extension technology has been widely used in various mobile terminals, including mobile phones, tablet computers, high-definition video players, and so on. The connection method is mainly based on the wired connection method, supplemented by the wireless transmission method. [0003] In the wired transmission mode, there are mainly four kinds of transmission interfaces at present: the first one adopts VGA (Video Graphics Array, Video Graphics Array) interface; the second one is a composite video interface, which adopts RCA (Radio Corporation of America ...
