Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
At present, in a case where the resolution of an original video image is not consistent with the resolution of a display device, in order to realize the viewing of the image, the resolution of the original video image is generally reduced to a resolution matching the display device in a whole by a video monitor in proportion, and then the reduced original video image is displayed by the display device connected to the video monitor.
For example, in the case where the resolution of a video is 8K Ultra High Definition (UHD) and the resolution of a display device is 4K Ultra High Definition video or High Definition video (HD), an existing method generally reduces an original video image of 8K to a 4K video image or a High Definition video image in a whole by a video monitor, and then displays the 4K video image or the High Definition video image on the display device.
However, the conventional method has at least the following problems:
in the shooting process, whether the people and the scenes at the key parts are focused accurately can be checked through the display equipment. However, after the original 8K video image is reduced, the display of the 4K ultra-high definition video or the display of the high definition video cannot determine whether focusing is accurate;
during the post-production of video, the 8K original video pictures cannot be used, resulting in an intermediate uncontrolled loss of quality. Therefore, neither a display of a 4K ultra-high definition video nor a display of a high definition video can realize exposure viewing of a sensitive area. And during the post-production of the video, the brightness and the like of the video image also need to be adjusted, which may cause that some details which need to be represented in a sensitive area are lost, and the loss of the details cannot be well represented on a display of the 4K ultra-high definition video or a display of the high definition video.
In summary, no matter the monitor monitors the accurate focus of the video image or monitors the picture quality of the sensitive area of the video image, the display of the 4K ultra high definition video or the display of the high definition video cannot accurately view the original 8K video image.
Based on this, the embodiment of the present application skillfully provides an ultra high definition video monitoring method supporting local screen enlargement and roaming, which is applied to an existing low-resolution video monitor, by respectively acquiring display instruction information and an original video image to be processed containing an area of interest, where the original video image to be processed is each frame image decoded from a video to be processed, and intercepting an image of the area of interest from the original video image to be processed, and processing the image of the area of interest and/or the original video image to be processed according to the display instruction information to generate an image to be displayed, and displaying the image to be displayed on a display screen of the video monitor, and/or sending the image to be displayed to a display device connected to the video monitor.
Therefore, the embodiment of the application can realize the pixel-level monitoring of the original video image by intercepting the image of the region of interest from the original video image to be processed, processing the image of the region of interest and/or the original video image to be processed according to the display instruction information to generate the image to be displayed, displaying the image to be displayed on the display screen of the video monitor, and/or sending the image to be displayed to the display device connected with the video monitor.

It should be understood that the transmission rate of the HDMI interface may also be set according to actual requirements, and the embodiments of the present application are not limited thereto.
For example, in the case where the transmission rate of the HDMI interface is 18Gbps, the HDMI interface is an HDMI2.0 input interface, so that the video to be processed can be acquired through the four-way HDMI2.0 input interface.
For another example, when the transmission rate of the HDMI is 48Gbps, the HDMI is an HDMI2.1 input interface, so that the video to be processed can be acquired through one HDMI2.1 input interface.
Step S220, the video monitor decodes the video to be processed to obtain an original video image to be processed including the region of interest.
It should be understood that the original video image to be processed is each frame image decoded from the video to be processed frame by frame.
That is, the processing procedure of the original video image to be processed is the processing procedure of each frame of image.
It should also be understood that the number of the regions of interest in the original video image to be processed may also be set according to actual requirements.
For example, the original video image to be processed may include one region of interest, may also include 2 regions of interest, may also include 4 regions of interest, and the like.
It should also be understood that the resolution of the original video image to be processed may also be set according to actual requirements, and the embodiments of the present application are not limited thereto.
For example, the resolution of the original video image to be processed may be 7680 × 4320, or 3840 × 2160, or the like.
In order to facilitate understanding of the embodiments of the present application, the following description will be given by way of specific examples.
Specifically, the video monitor may decapsulate the video to be processed to restore the original video image to be processed. And, the video monitor may also buffer the original video image to be processed.
In step S230, the video monitor intercepts an image of the region of interest from the original video image to be processed.
It should be understood that the resolution of the image of the region of interest may be set according to actual requirements, and the embodiments of the present application are not limited thereto.
For example, in the case that the resolution of the original video image to be processed is 7680 × 4320, the resolution of the image of the region of interest may be 3840 × 2160, or 1920 × 1080.
As another example, in the case where the resolution of the original video image to be processed is 3840 × 2160, the resolution of the image of the region of interest may be 1920 × 1080.
In order to facilitate understanding of the embodiments of the present application, the following description will be given by way of specific examples.
Specifically, the video monitor acquires attribute information corresponding to the region of interest, and the video monitor can determine the position of the region of interest in the original video image to be processed according to the attribute information corresponding to the region of interest, so that the video monitor can intercept the image of the region of interest from the original video image to be processed.
It should be understood that the specific information included in the attribute information may be set according to actual requirements, and the embodiment of the present application is not limited thereto.
For example, the attribute information may include a start coordinate of the region of interest on the original video image and a size of the region of interest.
It should be understood that the specific position of the start coordinate may be set according to actual requirements, and the embodiments of the present application are not limited thereto.
For example, in the case where the region of interest is rectangular, the start coordinate may be the coordinate of the vertex of the upper left corner of the rectangle.
It should also be understood that the specific manner in which the video monitor obtains the attribute information corresponding to the region of interest may also be set according to actual requirements, and the embodiment of the present application is not limited thereto.
Alternatively, in the case where a key for setting or adjusting the attribute information is provided on the video monitor, the attribute information may be set or adjusted by the key on the video monitor.
For example, in the case where a key for adjusting the size of the region of interest is provided on the video monitor, the size of the region of interest can be adjusted by the key information.
Alternatively, in the case where the video monitor is configured with a remote controller, the attribute information is set or adjusted by remote control information transmitted from the remote controller.
For example, in the case where a mapping relationship between the remote control information and the setting instruction of the attribute information is stored in the video monitor, the video monitor may receive target remote control information transmitted from the remote controller, and the video monitor may further query the target setting instruction corresponding to the target remote control information according to the mapping relationship, so that the monitor may set the attribute information with the target setting instruction.
For another example, in a case where a mapping relationship between the remote control information and the adjustment instruction of the attribute information is stored in the video monitor, the video monitor may receive target remote control information transmitted by the remote controller, and the monitor may further query a target adjustment instruction corresponding to the target remote control information according to the mapping relationship, so that the monitor may adjust the attribute information according to the target adjustment instruction.
Optionally, an HTTP server is built in the video monitor, and an interactive attribute information setting service is run on the HTTP server, so that the attribute information setting service on the HTTP server is accessible through a browser of the tablet device, and the attribute information is set or adjusted through an interactive page provided by the attribute information setting service.
It should be understood that the HTTP server may be a service program.
It should also be understood that an HTTP server may also be referred to as an HTTP server.
Alternatively, in the case where the display screen of the video monitor is a touch display screen supporting touch interaction, the attribute information is set or adjusted by interaction information of the touch display screen.
For example, in a case where an area for adjusting the size of the region of interest is correspondingly set on the touch display screen, the video monitor sets or adjusts the attribute information in response to the user operating the area for adjusting the size of the region of interest.
In step S240, the video monitor acquires display instruction information.
It should be understood that the display instruction information is used to indicate the display manner of the image.
It should also be understood that the information included in the display instruction information may be set according to actual requirements, and the embodiments of the present application are not limited thereto.
For example, the display instruction information may include at least one of the following information: the instruction information used for displaying the reduced image of the original video image to be processed, the instruction information used for displaying the original video image to be processed and the region of interest and the instruction information used for displaying the region of interest. The instruction information for displaying the region of interest may be instruction information for displaying one region of interest in the original video image to be processed, or may be instruction information for displaying a plurality of regions of interest in the original video image to be processed.
It should also be understood that the display instruction information may be preset or may be input by the user in real time, and the embodiment of the present application is not limited thereto.
And step S250, the video monitor processes the image of the region of interest and/or the original video image to be processed according to the display instruction information to generate an image to be displayed.
It should be understood that, the specific manner in which the video monitor processes the image of the region of interest and/or the original video image to be processed according to the display instruction information to generate the image to be displayed may be set according to actual requirements, and the embodiment of the present application is not limited thereto.
Alternatively, the video monitor may point-to-point process the image of the region of interest into an image of the first target resolution or image to be displayed. Wherein the first target resolution is a resolution of the display device.
For example, in the case where the resolution of the image of the region of interest is 3840 × 2160 and the resolution of the display device is also 3840 × 2160, the video monitor may point-to-point process the image of the region of interest into an image of the resolution of 3840 × 2160.
It should be understood that the specific resolution of the display device may be set according to actual requirements, and the embodiments of the present application are not limited thereto.
For example, in the case where the resolution of the original video image is 7680 × 4320 and the resolution of the image of the region of interest is 3840 × 2160 or 1920 × 1080, the resolution of the display device may be 3840 × 2160 or 1920 × 1080 or other resolutions. Here, the other resolution may be equal to or less than 7680 × 4320 and equal to or more than the resolution of the image of the region of interest.
As another example, in the case where the resolution of the original video image is 3840 × 2160 and the resolution of the image of the region of interest is 1920 × 1080, the resolution of the display device may be 1920 × 1080 or other resolutions. The other resolution here may be equal to or less than 3840 × 2160 and equal to or more than the resolution of the image of the region of interest.
At the same time, the first target resolution may also be smaller than the resolution of the display device, in which case the image point-to-point of interest will not fill the entire screen when displayed on the screen. Such as: the input video is 8K video, and the original resolution is: 7680X 4320; the resolution of the display device/screen is: 3840 × 2160; the size of the region of interest can be set to 3840 × 2160, at which time the image of the region of interest will fill the display; the size of the region of interest may also be set to: 1920 × 1080; 1/4, the picture of point-to-point display of the region of interest only occupies the display/display screen; the remaining 3/4 spaces not covered by the region of interest may also display thumbnails of the original video image so that the user can master the composition of the entire video frame.
Whether the point-to-point display image of the region of interest occupies the display or not, compared with the display effect of the whole reduced image of the original video image, the point-to-point display image of the region of interest displays the local picture of the region of interest in a partially enlarged manner. When the position of the interested area on the original image is adjusted by using keys and a roller wheel on the display or a remote controller of the display, the display effect is that an enlarged display area is displayed on the original image in a roaming way.
Alternatively, the video monitor may reduce the original video image to be processed to an entire reduced image of the original video image at the second target resolution. And the second target resolution is the resolution of the display device or the display screen.
For example, in the case where the original video image is an 8K video image, the video monitor may reduce the entire 8K video image to a 4K video image.
For another example, in the case where the original video image is an 8K video image, the video monitor may reduce the entire 8K video image into a thumbnail image, so that the thumbnail image may be displayed on the display screen of the video monitor.
It should be understood that the specific resolution of the display screen may be set according to actual requirements, and the embodiments of the present application are not limited thereto.
Further, in the case where the second resolution is the resolution of the display device, an image of at least one region of interest, the size of which is equal to or smaller than the resolution of the display device, may be superimposed on the entire reduced image of the original video image.
That is, the embodiments of the present application may display an image to be displayed in a manner similar to picture-in-picture.
It should be understood that the overlapping position of the image of the region of interest on the image of the whole reduced original video image may also be set according to actual requirements, and the embodiment of the present application is not limited thereto.
For example, an image of the region of interest may be superimposed on the lower right corner of the entire reduced image of the original video image.
Alternatively, in the case where the number of the regions of interest is plural, the video monitor may stitch images of the plural regions of interest to generate an image to be displayed.
It should be understood that the splicing manner of the images of the multiple regions of interest may also be set according to actual requirements, and the embodiment of the present application is not limited thereto.
