In the process of implementing the invention, the inventor finds that the following problems exist in the prior art: since the existing display displays an overall reduced image of an image, only the viewing of the image content is possible through the existing display, which cannot achieve the viewing of the pixel level of the image through the existing display. For example, during shooting, a user needs to determine whether a scene and a person are focused accurately through a display, but in the case where an existing display can only display a reduced-overall image, the user cannot accurately determine whether to focus.
Disclosure of Invention
An object of the embodiments of the present application is to provide a display and an image display method, so as to solve the problem that the prior art cannot realize the viewing of the image at the pixel level through the prior display.

And when the second display area is in a folded state, only the first display area can work, and the first display area can be used for displaying the reduced image, namely the second display area does not need to perform the display work, so that the energy can be saved.
In one possible embodiment, the second display area is disposed in the first extending direction of the first display area.
In one possible embodiment, the second display area is disposed in a second extending direction of the first display area perpendicular to the first extending direction.
In one possible embodiment, the first display area and the second display area are both rectangular.

FIG. 1 is a schematic diagram of a display provided by an embodiment of the present application;
FIG. 2 illustrates a schematic diagram of another display provided by embodiments of the present application;
fig. 3 shows a flowchart of an image display method provided in an embodiment of the present application.
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.
In the description of the present invention, it should be noted that the terms "left side", "right side", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
At present, in a case where the resolution of an image to be displayed and the resolution of a display (e.g., a monitor or the like) are not consistent, in order to realize the monitoring of the image, it is common to first downscale the image as a whole to a resolution matching the display by using an image conversion device, and then display the downscaled image by using the display.
For example, when the resolution of a video is a resolution corresponding to an 8K Ultra High Definition (UHD) video and the resolution of a display is a resolution corresponding to a 4K Ultra High Definition (HD) video or a resolution corresponding to a High Definition (HD) video, a conventional method generally reduces an 8K video image to the pixel size of the 4K Ultra High Definition video or the HD video image in a whole by an image conversion apparatus in proportion, and then displays the 4K video image or the HD video image on the display connected to the image conversion apparatus.
However, the conventional display has at least the following problems:
during shooting, a user needs to determine whether the characters and scenes of key parts are focused through a display. However, since the existing display displays the entire reduced image of the image, the user cannot accurately determine whether to be focused through the entire reduced image displayed by the existing display;
during the post-production of video, images at a first resolution (e.g., a resolution corresponding to 8K ultra high definition video) are unusable, resulting in an intermediate uncontrolled loss of quality. Therefore, in a case where the image conversion apparatus can perform only the entire reduction of the image of the first resolution, the display of the second resolution (for example, the resolution corresponding to the 4K ultra high definition video or the resolution corresponding to the HD video, etc.) cannot realize the detailed view of the sensitive region in the image. And, during the post-production of the video, the brightness of the video image needs to be adjusted (for example, the picture can be adjusted to be brighter or darker by the special effect of the video), which may cause some details that need to be represented in the sensitive area to be lost, and the loss of the details cannot be seen in the existing display.
In summary, neither accurate focus or quality of the picture in sensitive areas of the picture is monitored, and no support is provided by the existing displays.
Based on this, embodiments of the present application provide a display that displays a reduced image of a target image through a first display area in the display, and also displays an image of a first partial area in the target image through a second display area disposed adjacent to the first display area. Wherein the resolution of the second display area is less than the resolution of the target image.
Therefore, the second display area in the embodiment of the present application may display the image of the first partial area, so that the second display area may realize a point-to-point display with respect to the image of the first partial area, that is, a pixel-level view is realized for the first partial area.
And the display in the embodiment of the application can also simultaneously display the reduced image of the target image and the image of the first local area in the target image, so that the user can see not only the content of the target image but also the details of the first local area in the target image, and great convenience is brought to the user.
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 7680 × 4320.
The resolution of 4K ultra high definition video is 3840 × 2160.
The resolution of high definition video is 1920 × 1080.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating a display according to an embodiment of the present disclosure. The display as shown in fig. 1 includes a first display area 110 and a second display area 120 disposed on the right side of the first display area 110, the first display area 110 being for displaying a reduced image of a target image, and the second display area 120 being for displaying an image of a first partial area in the target image. Wherein the resolution of the second display area 120 is smaller than the resolution of the target image.
It should be noted here that the fact that the resolution of the second display region 120 is smaller than the resolution of the target image means that the product of horizontal pixels and vertical pixels in the resolution of the second display region 120 is smaller than the product of horizontal pixels and vertical pixels in the resolution of the target image.
It should be understood that, although fig. 1 shows that the first display area 110 is disposed at the left side of the second display area 120, it should be understood by those skilled in the art that the relative positions of the first display area 110 and the second display area 120 may be set according to actual requirements, as long as it is ensured that the first display area 110 and the second display area 120 are disposed adjacently, and the embodiment of the present application is not limited thereto.
For example, the second display area 120 may be disposed in the first extending direction of the first display area 110.
It should be understood that the specific direction of the first extending direction may be set according to actual requirements, and the embodiments of the present application are not limited thereto.
For example, the first extending direction may be a horizontal direction in fig. 1, so that the second display area 120 may be disposed at the left or right side of the first display area 110.
For another example, the second display region 120 may be disposed in a second extending direction of the first display region 110 perpendicular to the first extending direction.
It should be understood that, since the first extending direction may be set according to actual requirements, and thus the second extending direction may also be set according to actual requirements, the embodiment of the present application is not limited thereto.
For example, in the case where the first extending direction may be a horizontal direction in fig. 1, then the second extending direction is a vertical direction in fig. 1, i.e., the second display area 120 may be disposed at an upper side or a lower side of the first display area 110.
It should also be understood that the resolution of the target image may be set according to actual requirements, and the embodiments of the present application are not limited thereto.
For example, the resolution of the target image is 7680 × 4320.
It should also be understood that the shape, size, resolution and the like of the first display area 110 may be set according to actual requirements, and the embodiment of the present application is not limited thereto.
For example, the first display region 110 has a rectangular shape.
For another example, the resolution of the first display area 110 may be 3840 × 2160, or 1920 × 1080.
It should also be understood that the shape, size, resolution, and the like of the second display area 120 may also be set according to actual requirements, and the embodiment of the present application is not limited thereto.
For example, the second display area 120 has a rectangular shape.
For another example, the resolution of the second display area 120 may be 3840 × 2160, or 1920 × 1080.
In addition, it should be noted here that the resolution of the first display area 110 and the resolution of the second display area 120 may be the same.
It should also be understood that the specific form of the reduced image may be set according to actual requirements, and the embodiment of the present application is not limited thereto.
For example, the reduced image may be a thumbnail of the target image. Wherein the thumbnail may be a thumbnail obtained after compressing the target image. Thus, while the first display area 110 displays the thumbnail, it can display the thumbnail in the center area of the first display area 110.
For another example, the reduced image may be an overall reduced image adapted to the resolution of the first display region 110 (for example, in the case where the target image is an image of 8K resolution and the resolution of the first display region 110 is 4K resolution, the overall reduced image may be a 4K resolution image), and the like.
It should also be understood that the first local region may be referred to as a first region of interest, may also be referred to as a first sensitive region, may also be referred to as a first region of interest, and so on.
It should also be understood that, although fig. 1 shows that the display includes one second display area 120, it should be understood by those skilled in the art that, in the case that the target image to be viewed also includes a second partial area, in order to avoid the user repeatedly switching the images displayed by the second display area 120, a third display area (not shown) may be further provided, and the third display area may be used to display the images of the second partial area in the target image, so that the embodiment of the present application may display a plurality of partial areas simultaneously through the display.
It should also be understood that the position, shape, size, resolution and the like of the third display area may be set according to actual requirements, and the embodiment of the present application is not limited thereto.
For example, the third display region may be rectangular in shape.
For another example, in the case where the first display region 110 is disposed at the left side of the second display region 120, the third display region may be disposed above the second display region 120.
Furthermore, it should be noted here that, in the case where the target image further includes a third partial region, the display may further be provided with a fourth display region, a fifth display region, and the like.
In addition, when considering that the user may have a need to view only the entire reduced image, the second display region 120 is still in operation, which may cause a waste of power.
Referring to fig. 2, fig. 2 is a schematic diagram of another display provided in an embodiment of the present application. As shown in fig. 2, the second display region 220 may include a foldable region 221 and a non-foldable region 222, and the foldable region 221 may be disposed between the first display region 210 and the non-foldable region 222. Wherein the foldable area 221 can be used for folding the display.
Thus, in the unfolded state of the second display area 220, the foldable area 221 and the non-foldable area 222 can be used together to display the image of the first partial area, and at this time, the first display area 210 can also display the reduced image; in the folded state of the second display area 220 (or the non-folded area 222 is folded), only the first display area 210 may be operated, and the first display area 210 may be used for displaying the reduced image, that is, the second display area 220 does not need to perform any more display operation.
It should be understood that, although the second display area 220 is described as an example, a person skilled in the art should understand that, in the case that the display further includes another display area such as a third display area, the other display area such as the third display area may also be arranged in the manner of the second display area 220, and the embodiment of the present application is not limited thereto.
In addition, it should be noted here that the manner in which the display acquires the reduced image and the image of the first local area may be set according to actual needs, and the embodiment of the present application is not limited to this.
Optionally, the display may comprise a first input interface operable to obtain the reduced image and the image of the first local area sent by an image conversion device connected to the display.
That is, the display may be a display used in cooperation with the image conversion apparatus, so that after the image conversion apparatus processes the target image, it may directly transmit the processing result to the display, so that the display directly displays the reduced image and the image of the first partial area.
Optionally, the display may comprise a second input interface and a processor connected to the second input interface. The second input interface may be configured to obtain a target image, and the processor may be configured to process the target image to obtain a reduced image and an image of the first local area.
That is, the display may be a display provided with a function of the image conversion device, so that after the display acquires the target image, the processor may scale the target image to obtain a reduced image, and also cut out an image of the first partial region from the target image, and then display the reduced image and the image of the first partial region.
It is to be understood that the second input interface may be connected to the capturing device so that the image or video transmitted by the capturing device may be captured and processed by the processor.
It should also be understood that the specific device of the acquisition device may be set according to actual requirements, and the embodiments of the present application are not limited thereto.
For example, the acquisition device may be a camera or the like.
It should also be understood that the specific area of the first partial area may be set according to actual requirements, and the embodiments of the present application are not limited thereto.
For example, the switching mode of the display may be set (i.e. the position of the first partial area has been determined at this time), in which case the display has only one switching mode.
For another example, the display may determine the first local area via a remote control cooperating with the display. And the remote controller may be provided with number keys 1 to 9, and each number key may correspond to one preset partial region, so that the user may determine the first partial region by operating the number keys 1 to 9. Wherein, the number key 1 can correspond to the area of the upper left corner of the target image; the number key 2 can correspond to the upper middle area of the target image; the number key 3 can correspond to the area of the upper right corner of the target image; the number key 4 can correspond to the middle area on the left side of the target image; the number key 5 can correspond to the central area of the target image; the number keys 6 may correspond to the middle area of the right side of the target image; the number keys 7 can correspond to the area of the lower right corner of the target image; the number keys 8 can correspond to the middle area of the lower part of the target image; the numeric key 9 may correspond to an area in the lower right corner of the target image.
Correspondingly, the specific area of the second local area may also be set according to actual requirements, and the embodiment of the present application is not limited to this.
It should be noted that the display in the embodiment of the present application may also be referred to as a monitor, and the embodiment of the present application is not limited thereto.
In addition, it should be noted that the display in the embodiment of the present application may display an image (for example, an image of the first local area in the reduced image and the target image) by itself, or may transmit the displayed image to another device (for example, another monitor).
Therefore, the second display area in the embodiment of the present application may display the image of the first partial area, so that the second display area may realize a point-to-point display with respect to the image of the first partial area, that is, a pixel-level view is realized for the first partial area.
And the display in the embodiment of the application can also simultaneously display the reduced image of the target image and the image of the first local area in the target image, so that the user can see not only the content of the target image but also the details of the first local area in the target image, and great convenience is brought to the user.
In addition, it should be noted that, although the display is described above, it should be understood by those skilled in the art that the display may be configured or modified according to actual requirements.
As shown in fig. 3, fig. 3 is a flowchart illustrating an image display method provided in an embodiment of the present application. The image display method as shown in fig. 3 is applicable to a display, which may be the display shown in fig. 1 and 2, and includes:
in step S310, a reduced image of the target image and an image of the first local area in the target image are acquired.
It should be understood that the target image may be an image or a frame of image in a video.
It should also be understood that the process of obtaining the reduced image of the target image and the image of the first partial region in the target image may be set according to actual requirements.
For example, a reduced image of the target image and an image of the first local area in the target image may be acquired by the image conversion apparatus.
For another example, the display may process the target image to obtain a reduced image of the target image and an image of the first local area in the target image.
In step S320, the reduced image is loaded into the first display area of the display for display.
In step S330, the image of the first local area is loaded into the second display area of the display for display.
It should be noted here that the image display method may be correspondingly set in the case where the display is in a folded state or the display further includes a third display or the like.
