Description
Technical Field
The application relates to the technical field of computers, in particular to a method, a device and a terminal for displaying double images.
Background
When it is desired to compare two images of spatially related content, for example two remote sensing images taken at different times in the same area, two images taken of the same building under different weather conditions, or two images taken of the same baby by means of a color camera and by means of b-ultrasonography, it is common practice in current media to display the two images completely and independently separately at two locations. Thus, when an observer compares two images, the observer needs to look at one of the images, analyze a certain feature in the image, adjust the sight line to the other image, find a corresponding position in the other image according to the position of the feature in the previous image, and then judge whether the feature changes on the other image. Typically, to complete the contrast of the entire image, the viewer needs to look multiple times between the two images.
This type of contrast, which enables the contrast of two images whose contents are spatially related to each other, requires the viewer to continuously adjust the line of sight. If the attention of the observer is not focused or the attention of the observer is interrupted by a sudden event, the observer often loses the sight of the feature being compared, and thus the observer needs to spend time and energy to search again, resulting in low image comparison efficiency and poor user experience.
Disclosure of Invention

loading the first image into the first display area for display, and loading the second image into the second display area for display, wherein the content displayed in the first display area and the content displayed in the second display area are kept continuous in space during the movement of the dividing line.
In the embodiment of the application, the contents displayed by the first image and the second image are continuous in space, so that when a user observes a feature, the user only needs to keep the sight line at the position of the feature, and the first image and the second image at the position are switched by moving the dividing line, so that the contrast of the feature between the two images can be completed, and the user does not need to switch the sight line between the two independently arranged images.
Furthermore, in the embodiment of the present application, the dividing line may provide a reference point for the user's line of sight, and even if the user's line of sight leaves the display interface due to an unexpected event (e.g., a suddenly inserted conversation), the user may quickly switch the line of sight back to the previous viewing position with reference to the dividing line at a later time. The contrast efficiency of the image is improved, and the user experience is improved.

In the embodiment of the application, the whole display interface can be completely traversed by moving the segmentation line from one end of the display interface to the other end of the display interface. When the user wants to carefully compare all details of the two images, the user only needs to move the gaze along with the dividing line to compare the first and second images without repetition and completely. The user is prevented from frequently missing or repeating a look because there is no reference to help control the line of sight.
With reference to the first aspect, in a second possible line of sight approach, the dividing line is a curved line.

and moving the dividing line in the display interface according to a preset moving track so as to change the relative size of the first display area and the second display area.
In the embodiment of the application, the dividing line can automatically move along the moving track, so that the contents of the two images can be compared seamlessly without user operation.
With reference to the first aspect, in a fifth possible implementation manner,
the first image and the second image are remote sensing images taken at different times.
In the embodiment of the application, the first image and the second image are remote sensing images shot at different time, and the remote sensing images have the characteristics of wide coverage and less interference and are particularly suitable for being used when a disaster happens, so that the embodiment of the application is beneficial to mastering the disaster situation in the disaster and mastering the reconstruction situation after the disaster.
With reference to the first aspect, in a sixth possible implementation manner, after the setting and displaying the first image in the first display area and the setting and displaying the second image in the second display area, the method further includes:

And responding to the movement operation executed by the user on the display interface, and synchronously moving the first image and the second image in the display interface.

and when the second image cannot fill the second display area, displaying the content in the first image in a spatially continuous mode in an area which is not filled by the second image in the second display area.
In the embodiment of the application, the content in the first image is displayed in the second display area in the area which is not filled by the second image in a manner of keeping the content continuous in space, so that when the second image cannot fill the second display area, the content displayed in the second display area can still keep continuous in space.

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.
Referring to fig. 1, the present embodiment provides a terminal 10, where the terminal 10 may be a PC (personal computer), a tablet computer, a smart phone, a PDA (personal digital assistant), and the like.
In this embodiment, the terminal 10 may include: communication interface 11, display 12, memory 13, and processor 14 connected to communication interface 11, memory 13, and display 12.
The communication interface 11 may be a hardware interface in a physical sense or a logical interface in a software sense. When a first image and a second image showing two contents in spatial succession need to be compared, the terminal 10 may receive the first image and the second image through the communication interface 11.
The Display 12 may be a Display 12 made of LCD (liquid crystal Display), LED (Light-Emitting Diode), or OLED (Organic Light-Emitting Diode).
As shown in fig. 2, the display 12 may display a display interface 121, where the display interface 121 includes a dividing line 122, and both ends of the dividing line 122 extend to the edge of the display interface to divide the display interface 121 into a first display area 123 and a second display area 124.
The memory 13 may be, for example, a magnetic disk, a ROM, or a RAM, or any combination thereof, for storing a program necessary for executing the display method of the dual images. Illustratively, in addition to the memory 13, the terminal 10 can include program instructions stored in ROM, RAM, or other types of non-transitory storage media, or any combination thereof.
The processor 14 may be a chip such as a CPU (Central Processing Unit, Central Processing Unit 14), an MCU (micro controller Unit), an FPGA (Field-Programmable gate array), or the like.
In the following, a detailed description will be given of how to process the first image and the second image and how to display the first image and the second image in the form of a method embodiment.
Referring to fig. 3, an embodiment of the present application provides a method for displaying a dual image, which may be executed by the terminal 10, and the method may include: step S100 and step S200.
Step S100: a first image and a second image are acquired with contents spatially associated.
Step S200: loading the first image into the first display area for display, and loading the second image into the second display area for display, wherein the display content in the first display area and the display content in the second display area are kept continuous in space during the movement of the dividing line.
The flow of the above method will be described in detail with reference to the drawings.
Step S100: a first image and a second image are acquired with contents spatially associated.
Before comparison, a user needs to shoot an image needing comparison. According to different practical application scenes, images needing to be compared are different. For example, a pre-disaster remote sensing map of a certain area photographed by a satellite (or an unmanned aerial vehicle, etc.) in advance is a first image. And after the area has a geological disaster, the post-disaster remote sensing map of the area is shot as a second image through a satellite (or an unmanned aerial vehicle and the like), so that the two remote sensing maps are compared. For another example, a live view in a normal case of a certain building photographed in advance is a first image. And after the building is damaged, the shot live-action image of the damaged building is a second image, so that the two live-action images are compared. Also for example, the user may be photographed simultaneously using an X-ray emitter and a conventional lens to obtain a first image of the user as an X-ray map and a second image as an RGB map, thereby comparing the X-ray map and the RGB map.
In other words, the first image may be an image of an object that is photographed first, and the second image may be an image of the object that is photographed later; or the first image and the second image are two images obtained by shooting the same object by different shooting means.
In addition, the first image and the second image are convenient to compare, and the positions of the first image and the second image when being shot are required to be the same, so that the contents in the first image and the second image can be the same in view angle, and the comparison is convenient. The content in the first image and the content in the second image are obtained by shooting the same object at the same machine position and view angle, so that the content in the first image and the content in the second image form related content in space.
After the first image and the second image are obtained by photographing, the user may input the first image and the second image onto the terminal 10. Accordingly, the terminal 10 acquires the first image and the second image.
The terminal 10 may perform step S200 upon obtaining the first image and the second image.
Step S200: loading the first image into the first display area for display, and loading the second image into the second display area for display, wherein the display content in the first display area and the display content in the second display area are kept continuous in space during the movement of the dividing line.
The terminal 10 may load the first image to the first display area 123 such that the first image is displayed in the first display area 123. At the same time, the terminal 10 also loads the second image to the second display area 124 so that the second image is displayed in the second display area 124.
It is noted that for ease of comparison, the display content in the first display area 123 and the display content in the second display area 124 need to be spatially continuous. For example, as shown in fig. 4, the first image a and the second image B are images taken of the same building C at different times, and then, when displayed, the first display area 123 is displayed at the dividing line 122 until the building C is taken of the roof C1 at the first time, and the second display area 124 continues to display the building C at the dividing line 122 and then taken of the roof C1 at the second time, so that the display contents in the first display area 123 and the display contents in the second display area 124 form a spatial continuity.
In the present embodiment, as an alternative way to realize the spatial continuity of the display content, the terminal 10 sets a position in the first display area 123 corresponding to the center in which the first image is preset, and a position in the second display area 124 corresponding to the center in which the second image is preset, in accordance with a criterion that the display content is spatially continuous. In this way, the terminal 10 loads the first image in such a manner that the center sets the position in the first display area 123, and loads the second image in such a manner that the center sets the position in the second display area 124, it is possible to realize that the display contents in the first display area 123 and the display contents in the second display area 124 are spatially continuous.
As another alternative way to achieve the display content being spatially continuous, the terminal 10 may set the first image and the second image into the display interface 121 in a manner that the content is overlapped, set the transparency of the second image in the first display area 123 to 100% and the transparency of the first image to 0%, and set the transparency of the second image in the second display area 124 to 0% and the transparency of the first image to 100%. In this way, the first display area 123 displays only the content in the first image, the second display area 124 displays only the content in the second image, and the display content in the first display area 123 and the display content in the second display area 124 are also spatially continuous.
After the first image and the second image are displayed, a user can adjust the display of the first image and the second image in a man-machine interaction mode or an automatic control mode.
Referring to fig. 5 and 6, as an example of adjusting the display of the first image and the second image, a user may adjust the position of the dividing line 122 through a human-computer interaction manner or an automatic control manner.
Specifically, the dividing line 122 is a straight line or a curved line movable in the display interface 121. When the first image and the second image are loaded, the dividing line 122 may be located at an initial position in the display interface 121, for example, at the middle of the display interface 121, so as to divide the display interface 121 into two first display areas 123 and second display areas 124 with the same size and shape.
Regarding the way of human-computer interaction:
the user may drag the dividing line 122 by human-computer interaction with the terminal 10, for example, the user may touch on the dividing line 122 and move in the arrow direction. In this way, the terminal 10 may generate a dragging track corresponding to the dragging operation, and move the dividing line 122 according to the dragging track, corresponding to the dragging operation of detecting the dragging operation of the user dragging the dividing line 122. Based on the movement of the dividing line 122, the relative sizes of the first display area 123 and the second display area 124 are correspondingly changed, so that the contents displayed by the first image and the second image are correspondingly changed, and the display of the first image and the second image is adjusted.
In fig. 6, the dividing line 122 is a diagonal line, and the dividing line 122 can move in a direction perpendicular to the dividing line 122. In order to keep the display interface 121 still being divided during the movement, the length of the dividing line 122 needs to be adjusted accordingly. When the dividing line 122 needs to be increased, the terminal 10 may extend the dividing line 122 in a straight line manner, so that the dividing line 122 continues to be in contact with any two sides in the display interface 121; and, when the dividing line 122 needs to be shortened, the terminal 10 may shorten the dividing line 122 in a straight line manner, still keeping the dividing line 122 in contact with any two sides in the display interface 121.
Regarding the manner of automatic control:
the terminal 10 presets the moving track of the dividing line 122 in the display interface 121. When the user can input a movement instruction for controlling the dividing line 122 to start the automatic movement to the terminal 10 (for example, a key for controlling the dividing line 122 to start the automatic movement is displayed in the display interface 121, and the user can input the movement instruction to the terminal 10 by touching the key), the terminal 10 can move the dividing line 122 in the display interface 121 according to the movement track in response to the movement instruction, so as to change the relative sizes of the first display area 123 and the second display area 124. For example, as shown in fig. 5, the terminal 10 may first control the dividing line 122 to move from the initial position to the right side of the display interface 121 at a constant speed in a direction perpendicular to the dividing line 122, then to move from the right side of the display interface 121 to the left side of the display interface 121 at a constant speed in a direction perpendicular to the dividing line 122, and finally to move from the right side of the display interface 121 to the initial position in a direction perpendicular to the dividing line 122.
It should be noted that, since the display content in the first display area 123 and the display content in the second display area 124 are spatially continuous by setting the image position or by overlapping the images, the movement of the dividing line 122 does not affect the continuity of the content, i.e., the content displayed in the first display area 123 and the content displayed in the second display area 124 are continuously spatially continuous during the movement of the dividing line 122.
It will be appreciated that by moving the dividing line 122, different content at different locations and spatially continuous in the first and second images can be displayed in contrast. For example, the first image is a remote sensing image of a city before a disaster, and the second image is a remote sensing image of the city after the disaster, and by comparing and displaying spatially continuous areas before and after the disaster, the viewer can clearly know the development situation of the disaster, the serious situation of the disaster, the reconstruction situation after the disaster, and the like.
Referring to fig. 7, as an example manner of adjusting the display of the first image and the second image, a user may zoom and move the first image and the second image through human-computer interaction.
Specifically, the display interface 121 displays an enlargement key 125, a reduction key 126, and a restoration key 127.
Alternatively, the user may perform the zoom-in operation by touch-pressing a finger onto the zoom-in key 125 in the display interface 121. Accordingly, the terminal 10 can synchronously enlarge the first image and the second image in the display interface 121 in response to the enlargement operation. Wherein, the pressing time of the enlargement key 125 may correspond to the enlargement factor of the first image and the second image, and the longer the pressing, the larger the enlargement factor of the first image and the second image.
Alternatively, the user may perform the zoom-out operation by pressing a finger touch on the zoom-out key 126 in the display interface 121. Correspondingly, the terminal 10 synchronously reduces the first image and the second image in the display interface 121 in response to the reduction operation. Wherein, the duration of pressing the reduction key 126 may correspond to the reduction multiple of the first image and the second image, and the longer the pressing, the larger the reduction multiple of the first image and the second image.
Alternatively, the user may slide a finger in the display interface 121 to perform a moving operation, for example, slide in the direction shown in fig. 7, and the terminal 10 may move the first image and the second image in the display interface 121 synchronously in response to the moving operation.
Finally, if the user touches and presses the resume key 127, the resume operation is performed. Accordingly, the terminal 10 can synchronously restore the first image and the second image to the display condition at the time of the initial loading in response to the reply operation.
When the size of the first image is larger than that of the second image, if the user adjusts the display of the first image and the second image so that the second display area 124 cannot be filled with the second image, because of the size of the first display area 123 of the first image, and the content in the first image is not displayed in the first display area 123, the terminal 10 may display the content in the first image that is not displayed in the first display area 123 in an area that is not filled with the second image in the second display area 124 in a spatially continuous manner, so that the content displayed in the first display area 123 and the second display area 124 continues to be spatially continuous through the filling of the first image.
Referring to fig. 8, as an example manner of adjusting the display of the first image and the second image, a user may adjust the colors of the first image and the second image through human-computer interaction to more clearly distinguish and contrast the two images. For example, a first control for toning a first image is provided in the display interface 121 and a second control for toning a second image is provided in the display interface 121 by inserting controls, wherein the first control is displayed in the display interface 121 as a first slide bar 128 and the first control is displayed in the display interface 121 as a second slide bar 129. In this way, the user can slide the color-adjusting block in the first sliding rod 128 and/or the color-adjusting block in the second sliding rod 129 by touch, and correspondingly adjust the position of the color-adjusting block in the first sliding rod 128 and/or the color-adjusting block in the second sliding rod 129. Then, the terminal 10 correspondingly adjusts the RGB values of the first image and/or the second image according to the adjusted position of the toner patch in the first slide bar 128 and/or the adjusted position of the toner patch in the second slide bar 129 in response to the toner operation of the slide performed by the user.
Of course, the manner of providing two slide bars is an exemplary manner of the present embodiment, and is not a limitation to the present embodiment. For example, the display 121 displays a slide bar that the user selects which image the slide bar adjusts for.
Referring to fig. 9 in conjunction with fig. 1, based on the same inventive concept, an embodiment of the present application further provides a dual-image display apparatus 100, where the dual-image display apparatus 100 is applied to a terminal 10, and the dual-image display apparatus 100 includes:
an image obtaining module 110, configured to obtain a first image and a second image associated with content;
an image display module 120, configured to load the first image into the first display area 123 for display, and load the second image into the second display area 124 for display, where during the moving of the dividing line, the display content in the first display area 123 and the display content in the second display area 124 are kept continuous in space.
It should be noted that, as those skilled in the art can clearly understand, for convenience and brevity of description, the specific working processes of the above-described systems, apparatuses and units may refer to the corresponding processes in the foregoing method embodiments, and are not described herein again.
Some embodiments of the present application further provide a computer readable storage medium of a computer executable nonvolatile program code, which can be a general-purpose storage medium, such as a removable disk, a hard disk, and the like, and the computer readable storage medium stores the program code thereon, and when the program code is executed by a computer, the method for displaying a dual image according to any of the above embodiments is performed.
The program code product of the method for displaying a dual image provided in the embodiment of the present application includes a computer-readable storage medium storing the program code, and instructions included in the program code may be used to execute the method in the foregoing method embodiment.
In summary, the embodiment of the application provides a method, a device and a terminal for displaying a dual image. In the process of moving the dividing line, the content of the first image displayed in the first display area and the content of the second image displayed in the second display area can be kept continuous in space, so that a user can use the dividing line as a reference object and seamlessly analyze and compare the content in the first image and the content in the second image without adjusting the observation sight, thereby avoiding sight loss in the analysis process, improving the image comparison efficiency and improving the user experience.
In the embodiments provided in the present application, it should be understood that the disclosed apparatus and method may be implemented in other ways.
