Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
In the description of the present application, it should be noted that the azimuth or positional relationship indicated by the terms "front side", "rear side", etc. are based on the azimuth or positional relationship shown in the drawings, and are merely for convenience of describing the present application and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific azimuth, be constructed and operated in a specific azimuth, and thus should not be construed as limiting the present application. In the description of the present application, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.
Currently, in the case where the resolution of an image to be processed is inconsistent with the resolution of a display (for example, a monitor or the like), in order to realize the image monitoring, the image is generally reduced to a resolution matching the display in its entirety by using an existing image conversion device, and then the reduced image is displayed by using the display.
For example, in the case where the resolution of the video is that of an 8K ultra High Definition video (Ultra High Definition, UHD) and the resolution of the display is that of a 4K ultra High Definition video or that of a High Definition video (HD), the conventional method generally comprises firstly scaling the 8K video image to the pixel size of the 4K ultra High Definition video or the High Definition video in its entirety by using the conventional image conversion device, and then displaying the scaled 8K video image on the display connected to the image conversion device.
However, the conventional image conversion apparatus has at least the following problems:
during shooting, a display is needed to see if the person and scene at the key location are in focus. However, since the conventional image conversion apparatus can only reduce the image of the first resolution (for example, the resolution of 8K super-high definition video), whether or not to focus can not be accurately determined by the display of the second resolution (for example, the resolution of 4K super-high definition video or the resolution of high definition video, if the second resolution is smaller than the first resolution);
during post-production of video, the image of the first resolution cannot be used, resulting in an intermediate uncontrolled quality loss. Therefore, in the case where the conventional image conversion apparatus can only reduce the image of the first resolution, the display of the second resolution cannot realize the exposure view of the sensitive area. And, during the post-production of the video, adjustment of the brightness of the video image is also required (e.g., the picture can be adjusted to be brighter or darker by the special effect of the video), which may result in loss of some details that need to be displayed in the sensitive area, which loss of details cannot be seen with a display of the second resolution.
In summary, existing image conversion devices cannot provide support for monitoring the quality of a picture, whether it is accurately focused or local areas (e.g., sensitive areas) of the picture.
Based on the above, the embodiment of the application provides an ultra-high definition image conversion device, which is used for acquiring an input image to be processed through an input interface, displaying a thumbnail of the image to be processed through a display screen, selecting a cut-out area from the thumbnail through a selected area, and outputting an image of a target area in the image to be processed corresponding to the cut-out area through a first output interface. Wherein the resolution of the image of the target area is smaller than the resolution of the image to be processed.
Therefore, the embodiment of the application can intercept the image of the target area corresponding to the intercepted area from the image to be processed through the ultra-high definition image conversion device. And after the display receives the image of the target area, the display can realize point-to-point display, so that the pixel level of the image of the target area can be checked.
In addition, in the case that the display can realize point-to-point, the ultra-high definition image conversion device in the embodiment of the application can support not only accurate focusing monitoring of the picture, but also monitoring of the picture quality of a local area of the picture.
In order to facilitate understanding of the embodiments of the present application, some terms in the embodiments of the present application are first explained herein as follows:
the resolution of 8K ultra-high definition video is 7680X1420.
The resolution of 4K ultra-high definition video is 3840 x 2160.
The resolution of high definition video is 1920 x 1080.
Referring to fig. 1, fig. 1 shows a schematic diagram of an application scenario provided by an embodiment of the present application. As shown in fig. 1, the application scene includes an acquisition device 110, an ultra-high definition image conversion device 120, and a display 130.
It should be understood that the specific device of the collecting device 110 may be set according to actual requirements, and embodiments of the present application are not limited thereto.
For example, the acquisition device 110 may be a camera.
It should also be understood that the specific device of the ultra-high definition image conversion device 120 may be set according to actual requirements, so long as it is ensured that the ultra-high definition image conversion device 120 can achieve image capturing, and embodiments of the present application are not limited thereto.
It should also be understood that the specific device of the display 130 may be set according to actual requirements, and embodiments of the present application are not limited thereto.
For example, the display 130 may be a display having a resolution of 1920×1080, a display having a resolution of 3840×2160, or the like.
In order to facilitate an understanding of embodiments of the present application, the following description may be made with reference to specific examples.
Specifically, the ultra-high-definition image conversion device 120 acquires the image to be processed transmitted by the acquisition device 110 through the input interface (or the ultra-high-definition image conversion device 120 acquires the video to be processed transmitted by the acquisition device 110 through the input interface, and then the ultra-high-definition image conversion device 120 parses the image to be processed from the video to be processed). And, the ultra-high definition image conversion apparatus 120 may further entirely reduce the image to be processed to obtain a thumbnail of the image to be processed. And, the ultra-high definition image conversion apparatus 120 may also display a thumbnail of the image to be processed through its own display screen.
And, since the display screen may display the thumbnail, the user can view the content of the entire to-be-processed picture, and thus, the user may select the intercepting region based on the content of the picture, that is, the selecting region in the ultra-high definition image conversion device 120 may select the intercepting region from the thumbnail. And, since the cut-out area is selected from the thumbnail, the ultra-high definition image conversion apparatus 120 may determine a target area in the image to be processed corresponding to the cut-out area based on the correspondence between the thumbnail and the image to be processed (e.g., when the cut-out area is in the lower right corner of the thumbnail and occupies 1/4 area of the thumbnail, the target area may be in the lower right corner of the image to be processed and occupies 1/4 area of the image to be processed, etc.).
And, in case the ultra high definition image conversion apparatus 120 can acquire an image of the target area, the ultra high definition image conversion apparatus 120 can transmit the image of the target area to the display 130 through the first output interface. Wherein the resolution of the image of the target area is less than the resolution of the image to be processed, and the resolution of the display 130 may be greater than or equal to the resolution of the image of the target area and less than the resolution of the image to be processed.
Here, the resolution of the image of the target area being smaller than the resolution of the image to be processed means that the product of the horizontal pixels and the vertical pixels in the resolution of the image of the target area is smaller than the product of the horizontal pixels and the vertical pixels in the resolution of the image to be processed.
Correspondingly, the other resolutions are similar, and specific reference is made to the relevant descriptions, and will not be described in detail later.
And, the display 130 may acquire an image of the target area and display the image of the target area. Since the image of the target area is adaptively truncated based on the resolution of the display 130, a point-to-point display may be achieved.
It should be noted that the embodiment of the present application may be further extended to other suitable application scenarios, and is not limited to the application scenario shown in fig. 1.
For example, while FIG. 1 shows 1 display, those skilled in the art will appreciate that in an actual application scenario, the application scenario may include more displays.
Here, the display screen, the selection area, and the like in the ultra-high definition image conversion apparatus may be provided on any one side of the ultra-high definition image conversion apparatus, and for convenience of explanation, the description will be made below taking as an example that the display screen, the selection area, and the like may be provided on the front surface of the ultra-high definition image conversion apparatus.
Here, the ultra-high definition image conversion apparatus according to the present application may also be referred to as a monitor, and the embodiment of the present application is not limited thereto.
Referring to fig. 2, fig. 2 is a front view schematically illustrating an ultra-high definition image conversion apparatus 200 according to an embodiment of the application. The ultra high definition image conversion apparatus 200 as shown in fig. 2 includes a display screen 210 and a selection area 220 disposed on the right side of the display screen 210. The display screen 210 may be used to display a thumbnail 211 of the image to be processed received by the ultra-high definition image conversion device 200, and the selection area 220 may be used to select a clipping area from the thumbnail 211 of the image to be processed.
Here, the display screen 210 is mainly used to indicate where the image of the target area currently being output is located in the image to be processed (for example, the upper left corner position, the middle position, etc.).
It should be understood that the image to be processed may be a captured image or may be a frame of image in the input video.
Accordingly, the image of the target area hereinafter may be one image input by the ultra high definition image conversion apparatus 200, or may be one image in the video input by the ultra high definition image conversion apparatus 200.
It should also be appreciated that the resolution of the image to be processed may be set according to actual requirements, and embodiments of the present application are not limited thereto.
For example, the resolution of the image to be processed may be 7680×4320.
It should also be appreciated that the truncated region may also be referred to as a region of interest, may also be referred to as a sensitive region, etc.
It should also be understood that the specific location, specific size, specific number, etc. of the intercepting region may be set according to actual requirements, and embodiments of the present application are not limited thereto.
For example, the region of interest in a particular scene is often fixed, and the user may set the cut-out for that scene himself.
For another example, the number of the cut-out areas may be 1, 2, 4, or the like for the image to be processed.
It should be further understood that, although fig. 1 illustrates the selection area 220 disposed on the right side of the display screen 210, those skilled in the art should understand that the relative positional relationship between the selection area 220 and the display screen 210 may be set according to actual requirements, and the embodiment of the present application is not limited thereto.
For example, the selection area 220 may also be disposed below the display screen 210.
It should also be appreciated that the keys included in the selection area 220 may be set according to actual requirements, and embodiments of the present application are not limited thereto.
Alternatively, the selection area 220 may include a shortcut key area 221, where the shortcut key area 221 includes a plurality of shortcut keys, and each shortcut key of the plurality of shortcut keys may be used to quickly select a preset intercepting area from the thumbnail 211.
That is, each shortcut key may correspond to a preset intercepting region. Therefore, the embodiment of the application can quickly select the intercepting region through the shortcut key.
It should be understood that the positions of the shortcut keys, the total number of the shortcut keys, the positions of the preset intercepting areas corresponding to the shortcut keys, and the like may be set according to actual requirements, and the embodiment of the application is not limited thereto.
For example, with continued reference to FIG. 2, the shortcut key region 221 may be disposed in the upper left corner of the selection region 220.
For another example, with continued reference to fig. 2, the shortcut key region 221 may be provided with a shortcut key 2211, a shortcut key 2212, a shortcut key 2213, a shortcut key 2214, a shortcut key 2215, a shortcut key 2216, a shortcut key 2217, a shortcut key 2218, and a shortcut key 2219. Wherein, the shortcut key 2211 may correspond to a preset intercepting region located at the upper left corner of the thumbnail 211; the shortcut key 2212 may correspond to a preset intercepting region located in the middle of the upper portion of the thumbnail 211; shortcut key 2213 may correspond to a preset intercepting region located at the upper right corner of thumbnail 211; shortcut key 2214 may correspond to a preset intercepting region located in the middle of the left side of thumbnail 211; shortcut key 2215 may correspond to a preset intercepting region located at the center of thumbnail 211; shortcut key 2216 may correspond to a preset intercepting region located in the middle of the right side of thumbnail 211; shortcut key 2217 may correspond to a preset intercepting region located at the lower left corner of thumbnail 211; shortcut key 2218 may correspond to a preset intercepting region located in the middle of the lower portion of thumbnail 211; the shortcut key 2219 may correspond to a preset intercepting region located at the lower right corner of the thumbnail 211. Thus, in a case where the display screen 210 displays the thumbnail 211 of the image to be processed, the user can quickly select the center area of the thumbnail 211 as the preset cut-out area through the shortcut key 2215. Meanwhile, in order to facilitate the user to intuitively determine the size, position, etc. of the intercepting region, the display screen 210 may also be displayed with a detection frame 212 for identifying the intercepting region (or preset intercepting region).
In addition, it should be noted that although fig. 2 is described with 9 preset intercepting regions, it should be understood by those skilled in the art that the ultra-high definition image conversion device 200 may be provided with various modes of preset intercepting regions, and embodiments of the present application are not limited thereto.
For example, in the first mode, the ultra-high definition image conversion device 200 may set 3 preset intercepting regions with relatively large granularity; in the second mode, the ultra-high definition image conversion device 200 may set 6 preset intercepting regions with moderate granularity; in the third mode, the ultra-high definition image conversion device 200 may set 9 preset intercepting regions; in the fourth mode, the ultra high definition image conversion apparatus 200 may include only 1 preset cut-out region (e.g., the preset cut-out region may be a small image region in the middle of the thumbnail 211, etc.).
It should also be understood that the shortcut key may be a physical key or a virtual key on a software interface, and embodiments of the present application are not limited thereto.
Correspondingly, other keys in the selection area 220 may be physical keys or virtual keys, which will not be described in detail later.
It should also be understood that, in the case that the shortcut key is a physical key, the specific device of the shortcut key may be set according to actual requirements, and the embodiment of the present application is not limited thereto.
For example, the shortcut key may be a knob, a physical key capable of being pressed, or the like.
Optionally, the selection area 220 may further include a position adjustment key 222. The position adjustment key 222 may be used to adjust the position of the preset intercepting region (or, may implement the overall movement of the detection frame 212) without changing the size of the preset intercepting region.
That is, in the embodiment of the present application, the position of the detection frame 212 is adjusted by the position adjustment key 222 under the condition that the shape and the size of the detection frame 212 are not changed, so that the adjustment of the preset intercepting region is realized. Therefore, as the situation that the preset intercepting area is deviated from the target intercepting area wanted by the user may occur, the embodiment of the application can realize the adjustment of the position of the preset intercepting area through the position adjustment key 222, thereby meeting the requirements of the user.
It should be understood that the number of keys and the positions of the keys included in the position adjustment keys 222 may be set according to actual requirements, and the embodiment of the application is not limited thereto.
For example, with continued reference to FIG. 2, a position adjustment key 222 may be disposed in the lower right corner of the selection area 220.
For another example, the position adjustment keys 222 may include a first position adjustment key 2221 and a second position adjustment key 2222. The first position adjusting key 2221 may be used to adjust the position of the preset intercepting region along the first direction; the second position adjusting key 2222 may be used to adjust the position of the preset intercepting region along a second direction perpendicular to the first direction.
It should be understood that the specific direction of the first direction may be set according to actual requirements, and embodiments of the present application are not limited thereto.
For example, the first direction may be a horizontal direction. Correspondingly, the second direction may be a vertical direction perpendicular to the horizontal direction.
Optionally, the selection area 220 may further include an area adjustment key 223. The region adjustment key 223 may be used to zoom in or out the preset cut-out region. That is, the embodiment of the present application can adjust the size of the detection frame 212 through the area adjusting key 223, thereby realizing the adjustment of the size of the preset intercepting area, and further meeting the requirements of users.
It should be understood that the keys and key positions included in the area adjustment key 223 may be set according to actual requirements, and the embodiment of the present application is not limited thereto.
For example, with continued reference to FIG. 2, a zone adjustment key 223 may be disposed in the upper right corner of the selection zone 220.
For another example, the zone adjustment key 223 may include a first zone adjustment key (not shown). Therefore, the user can zoom in the preset intercepting region according to the preset zoom-in proportion through the first region adjusting key.
It should also be understood that the specific value of the preset amplification ratio may be set according to actual requirements, and embodiments of the present application are not limited thereto.
For example, the preset magnification ratio may be 1. Thus, in the case where the user presses the first region adjustment key for the first time, the preset enlargement region can be enlarged 1-fold. And, in the case that the user presses the first region adjustment key for the second time, the preset amplification region may be amplified by 1 time, etc.

It should be understood that the specific value of the preset reduction ratio may be set according to the actual requirement, and the embodiment of the application is not limited thereto.
For example, the preset reduction ratio may be 1 time. Therefore, when the user presses the second area adjusting key for the first time under the condition that the resolution of the preset intercepting area is the resolution of the 4K ultra-high definition video, the resolution of the preset intercepting area can be changed to be half of the resolution of the 4K ultra-high definition video. And when the user presses the second region adjustment key for the second time, the resolution of the preset intercepting region can be changed to 1/4 of the resolution of the 4K ultra-high definition video, and the like.
For another example, the zone adjustment key 223 may include a manual adjustment key (not shown). Therefore, the user can press the upper right corner of the manual adjustment key to reduce the preset intercepting region, and can press the lower left corner of the manual adjustment key to expand the preset intercepting region, so that the embodiment of the application can finely adjust the preset intercepting region through the manual adjustment key.
Optionally, the selection area 220 may also include a lock key 224. The lock button 224 may be used to lock the image to be processed from the video for repeated adjustment and monitoring of the image to be processed. That is, in the case where the ultra high definition image conversion apparatus 200 inputs a video or a plurality of images, a certain image (for example, an image to be processed) may be locked from the video or the plurality of images by the lock key 224, thereby acquiring a still frame picture.
Here, the conventional image conversion apparatus can only display a video, and cannot lock a still long-time display of one frame of image in the video. However, the ultra-high definition image conversion device in the embodiment of the application can lock one frame of image at the interested time, and can repeatedly adjust the locked image (for example, can adjust the size of the interception area for a plurality of times, etc.) and monitor the locked image.
It should be understood that the location, size, etc. of the locking key 224 may be set according to practical requirements, and the embodiment of the present application is not limited thereto.
For example, with continued reference to FIG. 2, the lock key 224 may be disposed below the shortcut key region 221 and also between the display 210 and the position adjustment key 222.
In addition, although the ultra-high definition image conversion apparatus 200 is described above, those skilled in the art will appreciate that the ultra-high definition image conversion apparatus 200 may also include other devices or modules, and embodiments of the present application are not limited thereto.
Alternatively, the ultra high definition image conversion apparatus 200 may include a controller.
Optionally, with continued reference to fig. 3, fig. 3 shows a schematic diagram of an ultra-high definition image conversion apparatus 300 according to an embodiment of the present application. The ultra high definition image conversion apparatus 300 as shown in fig. 3 may include an input interface 310, a first output interface 320, and a second output interface 330.
Wherein, the input interface 310 may be used to obtain an image to be processed or a video to be processed; the first output interface 320 may be used to output an image of a target area after the ultra high definition image conversion apparatus 300 acquires the image of the target area; the second output interface 330 may be used to output a thumbnail of the image to be processed, an image to be processed, or an intermediate resolution image obtained by reducing the resolution of the image to be processed, the intermediate resolution image having a resolution greater than that of the thumbnail and a resolution less than that of the thumbnail. The thumbnail refers to a small image after the image is processed in a compression mode.
For example, in the case where the resolution of the display connected to the ultra high definition image conversion apparatus is the resolution of 4K ultra high definition video, the intermediate resolution image may be an image of 4K resolution. That is, the intermediate resolution image may be adapted to the resolution of a display connected to the ultra high definition image conversion device.
It should be understood that the specific number of the first output interfaces 320 and the like may be set according to actual requirements, and the embodiment of the present application is not limited thereto.
For example, in the case where the image to be processed is an 8K video image, the ultra high definition image conversion apparatus 300 may include two first output interfaces. One of the first output interfaces is used for outputting a 4K video image intercepted from an 8K video image, namely the current first output interface can be connected with a display with 4K resolution; the other first output interface is used for outputting HD video images taken from 8K video images, i.e. the current first output interface may be connected to a HD resolution display. Thus, embodiments of the present application both utilize old equipment and enable pixel-level viewing of a localized area of an 8K video image when there is a 4K resolution display or HD resolution display. In addition, since there is no need to equip a display with 8K resolution, it is also possible to save costs.
Thus, in view of the fact that the 8K video image is only a pixel-level view with a large pixel size and is locally identical to the 4K video image or the HD video image, the embodiment of the present application can cut out a part of the 4K video image (or a part of the HD video image) from the 8K video image, so that any region in the 8K video image can be output and displayed on a 4K resolution display (or HD resolution display) through such conversion.
Furthermore, by this conversion, a complete 8K video image can also be monitored by a combination of multiple 4K resolution displays (or multiple HD resolution displays).
For example, a complete 8K video image may also be monitored by 4K resolution displays.
In the process of obtaining the thumbnail image by the ultra-high definition image conversion apparatus 300, the ultra-high definition image conversion apparatus 300 may also obtain the evaluation parameter of the image to be processed, and further may send the thumbnail image (or the image to be processed, or the image with intermediate resolution) and the evaluation parameter to the display when sending the thumbnail image (or the image to be processed, or the image with intermediate resolution) to the display.
It should be understood that the specific parameters included in the evaluation parameters may be set according to actual requirements, and embodiments of the present application are not limited thereto.
For example, the evaluation parameters may include brightness, waveform diagram, and the like of the image to be processed.
In addition, it should be noted that, in the case where the ultra-high definition image conversion apparatus 300 includes a plurality of output interfaces (for example, the first output interface 320 and/or the second output interface 330), only one output interface may be operated, a part of the output interfaces may be operated, or all of the output interfaces may be operated, that is, the ultra-high definition image conversion apparatus 300 may be externally connected to one display or a plurality of displays, and the embodiment of the application is not limited thereto.
In addition, although fig. 3 shows two output interfaces, those skilled in the art will appreciate that the ultra-high definition image conversion apparatus may also include other output interfaces, and embodiments of the present application are not limited thereto.
For example, the ultra high definition image conversion apparatus may further include a third output interface, and the like.
Therefore, the embodiment of the application can intercept the image of the target area corresponding to the intercepted area from the image to be processed through the ultra-high definition image conversion device. And after the display receives the image of the target area, the display can realize point-to-point display, so that the pixel level of the image of the target area can be checked.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application. It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.
The foregoing is merely illustrative of the present application, and the present application is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
