In the existing display device, when a user adjusts a local enlarged region horizontally or vertically, since the adjustment of the local enlarged region along one direction has a boundary limitation, when the local enlarged region has been adjusted to an edge of a picture, a system generally sends out a touch prompt tone to remind the user that the picture has reached the edge, and at this time, the user cannot adjust the local enlarged region along the same direction any more. If the user wants to view the edge of the picture, the picture needs to be reloaded for enlarged display, which causes low browsing efficiency and poor user experience.

In order to solve the above technical problem, an embodiment of the present application provides a display device, including:

a display configured to display a target picture;

a user interface configured to receive an instruction input by a user;

a controller configured to perform the method as follows, and as shown in fig. 6, is an overall flow chart of the method performed by the controller.

And step S101, responding to an instruction which is input by a user and indicates to display a target picture, and displaying the target picture in a display.

A user may input an instruction to the display device through the control apparatus 100, for example, a remote controller. Or the instruction can be input by the mobile terminal, such as a mobile phone and a tablet computer, by means of a touch screen.

In the application, the picture which is indicated to be viewed by the user is defined as the target picture.

In some embodiments, when the user operates with the remote controller, the user may enter an application program for viewing pictures through the touch remote controller, and click a corresponding picture to view the picture, where the display device is in a picture viewing mode. The controller displays the corresponding picture in a full screen manner in the display in response to an instruction of the user to view the picture.

In some embodiments, when the display device is in the picture viewing mode, the user may switch the target picture by touching the direction keys (up, down, left, and right) of the remote controller to view different pictures.

In some embodiments, when the user operates the mobile phone, the software application matched with the display device is firstly opened. At this time, the user can select to enter a remote control interface, that is, the content displayed on the touch screen of the mobile phone is a control interface of the display device, and specifically, the user can correspond to a plurality of keys of the remote controller, that is, the function of the remote controller is realized through the mobile phone, and then an instruction is sent to the display device through the remote control interface of the touch mobile phone, so that the display device enters a picture viewing mode.

In some embodiments, the picture displayed on the mobile phone may also be transmitted to the display device, and at this time, the target picture in the mobile phone may be displayed in the display device. For example, the mobile phone is connected with the display device in a wired connection mode of HDMI or USB, or the mobile phone is connected with the display device in a wireless screen projection mode, so that the function of synchronously displaying the pictures of the mobile phone and the display device is realized. Specifically, the display device may display all the screen contents in the mobile phone touch screen, or may display only a part of the screen contents in the mobile phone touch screen, which is not limited herein.

And S102, responding to an instruction which is input by a user and indicates that the target picture is locally amplified, and locally amplifying and displaying the target picture.

In the embodiment of the application, a user determines a region needing to be enlarged and displayed in a target picture through a local selection frame, namely a first local enlargement region.

And binding the corresponding relation between the image amplification instruction and the remote controller key in advance in the actual application process. For example, a picture enlarging key is disposed on the remote controller, specifically, referring to fig. 7, fig. 7 is a schematic diagram of the remote controller according to a feasible embodiment, the remote controller provided in fig. 7 has a picture enlarging key 101, and when a user touches the key, the remote controller sends a corresponding picture enlarging instruction to the controller, so that the controller performs a local enlarging display operation on a target picture, and the display device enters a picture enlarging mode. When the user touches the key or touches the return key again, the remote controller sends a picture amplification cancelling instruction to the controller, so that the controller controls the display device to exit the picture amplification mode and return to the picture viewing mode.

In some embodiments, the corresponding relationship between the start instruction and the plurality of remote controller keys may also be pre-bound, and when the user touches the plurality of keys bound to the image magnification instruction, the remote controller sends the image magnification instruction. In a feasible embodiment, the keys bound to the image magnifying instruction are direction keys (left, down, left, down), and the remote controller sends the image magnifying instruction to the controller only when the user continuously touches the keys (left, down, left, down) within a preset time. By adopting the binding method, the picture amplification instruction can be prevented from being sent out due to misoperation of a user. The embodiment of the application is only exemplary in providing several binding relationships between the starting instruction and the key, and the binding relationship between the starting instruction and the key can be set according to the habit of a user in the process of practical application, so that excessive limitation is not made.

The size of the local selection frame and the initial position of the local selection frame relative to the target picture may be determined according to requirements. The size and the initial position of the local selection frame are not limited in the embodiments of the present application, for example, the initial position of the local selection frame may be located in the center of the target picture, and when the user instructs the display device to enter the picture enlarging mode, the central portion of the target picture is first enlarged and displayed. For another example, the initial position of the local selection box may be located in the upper left corner of the target picture, or may be located in any position of the target picture.

In some embodiments, when the user uses the mobile phone for operation, the mobile phone can be controlled to enter the remote control interface, and then the key of the remote control interface is touched to realize the amplification of the target picture. Specifically, reference may be made to the method for controlling the image magnification by the remote controller in the foregoing embodiment, which is not described herein again.

In some embodiments, when the user operates with the mobile phone and the display device perform screen synchronous display, as shown in fig. 8a, the screen content in the touch screen of the mobile phone when the target picture is displayed is the screen content in the mobile phone touch screen, and the screens in the mobile phone and the display are both the target picture. When the user controls the picture to be locally amplified, a continuous click command needs to be sent to the mobile phone. The continuous click command refers to: in a preset period, the number of times that a user clicks the same area of the mobile phone touch screen exceeds a preset threshold value. For example: when a user continuously clicks a certain area of the mobile phone touch screen for 2 times within 1s, the certain area is regarded as a continuous click instruction, at this time, the target picture needs to be locally amplified, meanwhile, a local selection frame is displayed in the mobile phone touch screen, and the center of the local selection frame is the area clicked by the user. As shown in fig. 8b, a schematic diagram of a user clicking a mobile phone touch screen, where m is a position of the mobile phone touch screen when the user issues a continuous click instruction, and as shown in fig. 8c, after the user issues the continuous click instruction, the picture content in the mobile phone touch screen is displayed.

In some embodiments, when a user operates with a mobile phone, the target picture may be locally magnified when it is detected that a touch pressure value of the user on a certain area of a touch screen of the mobile phone exceeds a preset pressure threshold. And simultaneously, displaying a local selection frame in the mobile phone touch screen, wherein the center of the local selection frame is an area for a user to touch the mobile phone touch screen.

Step S201, in response to a partial enlargement display operation on the target picture, displaying an enlarged image of a first partial enlargement area in a display.

In the embodiment of the present application, the first local enlarged region means: and selecting the area in the target picture through the local selection frame.

Specifically, after the controller performs local amplification processing on the target picture, the first local amplification area is amplified and displayed on the display, so that a user can view the amplified image to observe the details of the target picture. When the display device is in the picture viewing mode, as shown in fig. 9a, an exemplary diagram of a target picture is displayed for the display, and at this time, the display displays the target picture in a full-screen manner; when the display device is in the picture enlarging mode, as shown in fig. 9b, an exemplary diagram of a first local enlarged area at the position of the target picture is enlarged and displayed for the display, and at this time, the display displays an image corresponding to the first local enlarged area in a full-screen manner.

In some embodiments, when the user uses the mobile phone to operate, after the user controls the picture to be locally enlarged, the picture content in the touch screen of the mobile phone may be a target picture including a local selection frame, as shown in fig. 8 c; at the moment, the first local amplification area, namely the content in the local selection frame in the mobile phone touch screen, is displayed in the full screen of the display, and the mobile phone and the display device are in partial picture synchronization. The first local amplification area can also be displayed in the mobile phone touch screen in an amplification way, at the moment, the edge of the mobile phone touch screen is equivalent to a local selection frame, the first local amplification area is displayed in the display in a full screen way, and the mobile phone and the display equipment are synchronous in all pictures.

And S202, when detecting that the display displays the enlarged image of the first local enlarged area, responding to a local selection frame moving instruction, controlling the local selection frame to move relative to the target picture, and updating and displaying the enlarged image of the first local enlarged area in the display.

When the display device is in a picture amplification mode, the controller responds to a local selection frame moving instruction input by a user, controls the local selection frame to move relative to the target picture, and further changes the image of the first local amplification area so as to view different details in the target picture.

In the practical application process, the user can move the local selection frame by touching the direction keys (up, down, left and right) of the remote controller. The controller keeps the position of the target picture unchanged, controls the local selection frame to move in the corresponding direction in response to the direction key touched by the user, and when the local selection frame moves to a new position, the controller confirms the first local amplification area in the local selection frame at the moment and displays the current first local amplification area on the display in a full-screen mode, so that the switching of the first local amplification area is realized, and the user can view details of all places of the target picture.

In some embodiments, different methods of switching the first locally enlarged region are provided. The method specifically comprises the following steps: the controller keeps the position of the local selection frame unchanged, and controls the target picture to move in response to the direction key touched by the user so as to realize the relative movement of the local selection frame relative to the target picture in the opposite direction. When the local selection frame is located at a new position relative to the target picture, the controller confirms the first local amplification area in the local selection frame at the moment and displays the current first local amplification area on the display in a full-screen mode.

In some embodiments, when the user operates with the mobile phone, the user may implement the movement of the local selection box by touching the touch screen of the mobile phone. When a target picture is displayed on the mobile phone touch screen, a user realizes the movement of the local selection frame by long-pressing and dragging the local selection frame, and at the moment, the user controls the local selection frame, namely when the user drags the screen to the right, the local selection frame moves to the right relative to the target picture. When the first local amplification area is displayed on the mobile phone touch screen, the user realizes switching of the first local amplification area by sliding on the mobile phone touch screen, so that the local selection frame moves.

In some embodiments, in order to make the user intuitively understand that the local zoom-in frame is located at a specific position of the target picture, so that the user can better control the first local zoom-in area to view the required details, a local zoom-in indication map is also provided.

The user can see the specific position of the local zoom-in frame in the target picture through the local zoom-in, as shown in fig. 9 b. At the moment, the user can observe the image of the local amplification area and can also observe the specific position of the local amplification frame in the target picture, so that the user can select the local amplification area better.

Specifically, the controller is further configured to perform the steps of:

acquiring a local amplification indicating image, wherein the local amplification indicating image comprises a thumbnail of the target picture and a local selection frame positioned in the thumbnail;

In some embodiments, the controller may control turning on and off of the partial enlargement indication map in consideration of user's desirability of the partial enlargement indication map.

When the user selects to open the local enlargement indication map, the display simultaneously displays the first local enlargement area and the local enlargement indication map, so that the user can see that the local enlargement frame is located at a specific position of the target picture. When the user selects to close the partial amplification indicating diagram, the display only displays the first partial amplification area, so that the user can view the image corresponding to the complete first partial amplification area, and the experience of the user is improved.

In the process of practical application, the corresponding relation between the local amplification indicating diagram command and the remote controller key is bound in advance. In some embodiments, the remote controller is provided with a local enlargement indication key, and when the user touches the local enlargement indication key, the controller controls the display device to turn on the local enlargement indication map. When the user touches the key or touches the return key again, the controller controls the display device to close the local enlarged indication map.

In some embodiments, the correspondence between the local enlargement indication map instruction and the picture enlargement key 101 may also be bound in advance. In a feasible embodiment, the key for the instruction binding of the partial enlargement indication map may be the key 101, and the specific triggering process may be long pressing of the key 101. For example, when the user presses the key 101 for a long time, the remote controller transmits a local enlarged instruction map opening instruction to the controller, so that the controller controls the display device to display the local enlarged instruction map. The time of the long press is not limited in the present application, and for example, the time of the long press may be 3s or more. When the user presses the key 101 again for a long time while the partial enlargement indication map is displayed, the remote controller transmits a partial enlargement indication map closing instruction to the controller, so that the controller controls the display device to close the partial enlargement indication map.

Step S203, if the local selection frame is located at the edge of the target picture, in response to an edge movement instruction for instructing the local selection frame to continue moving to the edge, switching the target picture to a candidate picture, controlling the local selection frame to move along the direction indicated by the edge movement instruction relative to the candidate picture, and updating and displaying the enlarged image of the second local enlarged area on the display.

In the embodiment of the present application, the second local amplification region refers to: and selecting the area in the candidate picture through the local selection frame.

Specifically, in response to an instruction from a user to instruct the local selection frame to move, the controller presents a first locally enlarged region in the local selection frame on the display. When the local selection frame moves to an edge of a certain side of the target picture, if the user continues to instruct the local selection frame to move towards the edge, that is, when the user inputs an edge movement instruction, the controller needs to switch the target picture to a candidate picture to control the local selection frame to move towards the edge relative to the candidate picture. At this time, the image selected by the local selection frame in the candidate picture, that is, the image corresponding to the second locally enlarged region, is displayed in the display.

In some embodiments, the edge movement instruction may be set to: the user indicates an instruction to move the local selection box in the direction of the edge. When the display device is in the picture enlargement mode and the local selection frame is located at one edge of the target picture, if the user continues to instruct the local selection frame to move towards the edge, for example, the local selection frame may move once or multiple times, and no limitation is particularly set on the number of movement instructions, the controller switches the target picture to the candidate picture at this time. And enabling the local selection frame to select a second local amplification area in the candidate picture, and controlling the display to update and display the image corresponding to the second local amplification area.

In some embodiments, the edge movement instruction may be set to: the edge moving instructions are a plurality of moving instructions used for indicating the local selection frame to move towards the edge, and the number of the plurality of moving instructions in the fixed period exceeds a preset threshold value. In the embodiment of the present application, the preset threshold value in the fixed period is not limited, and may be, for example, more than 3 times within 1 s. Compared with the foregoing embodiment, the case that the user touches the remote controller by mistake is considered, that is, the user does not want to switch the target picture, but the target picture may be switched due to the mistaken touch on the remote controller. Therefore, when the local selection frame is located at the edge of the target picture, the controller switches the target picture to the candidate picture only when the plurality of movement instructions indicated by the user meet the condition of the edge movement instruction, and the experience of the user is improved.

In some embodiments, the edge movement instruction may be set to: the edge movement instruction is a continuous movement instruction for instructing the local selection frame to continuously move towards the edge, and the duration of the continuous movement instruction exceeds a preset period. In the embodiment of the present application, the preset period is not limited, and for example, it may be determined that the edge movement instruction is received when the long press exceeds 2 s. When the local selection frame is positioned at the edge of the target picture, and the time that the user presses the direction key corresponding to the edge on the remote controller for a long time exceeds a preset period, the controller switches the target picture into the candidate picture.

In the embodiment of the present application, the candidate pictures may be a target picture, a mirror image of the target picture, and a composite picture. The synthesized picture is obtained by splicing the mirror image picture of the target picture and the target picture.

In some embodiments, if the candidate picture is the target picture, when the local selection box is located at the edge of the target picture, e.g., the rightmost side. The controller responds to the edge movement instruction, switches the target picture into a candidate picture, wherein the candidate picture is the target picture, and therefore the position of the local selection frame relative to the target picture is reset, so that the local selection frame can continue to move rightwards relative to the target picture. The local selection box may be reset at the other side edge of the target picture, i.e. the leftmost side, so that the user can continue to browse the target picture to the right. And at the moment, the second local amplification area selected by the local selection frame is still the local area in the target picture.

In some embodiments, if the candidate picture is a mirror picture of the target picture. Taking the example that the local selection frame moves to the rightmost side of the target picture, the controller responds to an edge movement instruction indicating that the local selection frame continues to move rightmost, and switches the target picture into a candidate picture, where the candidate picture is a mirror image picture, and specifically, the mirror image picture and the target picture are in a mirror image relationship with the edge as a center line. The controller resets the position of the local selection box relative to the mirror picture so that the local selection box can continue to move to the right relative to the mirror picture. The local selection box may be reset at the other side edge, i.e. the leftmost side, of the target picture. FIG. 10a is a schematic diagram illustrating the position of the local selection frame relative to the target picture before the edge move instruction is executed, where the local selection frame is located at the right edge of the target picture; as shown in fig. 10b, the position of the local selection frame is shown relative to the mirror image after the edge moving instruction is executed, where the local selection frame is located at the left edge of the mirror image, and the second local enlargement area is a local area of the left edge of the mirror image. The second local enlargement area is a mirror image of the first local enlargement area before the edge movement instruction is executed.

In some embodiments, if the candidate picture is a composite picture. Taking the example that the local selection frame moves to the rightmost side of the target picture, the controller splices the mirror image picture of the target picture and the target picture in response to an edge movement instruction indicating that the local selection frame continues to move rightmost, specifically, the mirror image picture and the target picture are in a mirror image relationship with the edge as a center line, and at the same time, the mirror image picture and the target picture are spliced with the edge as a coincidence line to obtain a composite picture. The controller splices the mirror image picture and the target picture in response to the edge movement instruction, as shown in fig. 11a, which is a schematic diagram after splicing the mirror image picture and the target picture. The controller continues to control the local selection frame to move relative to the composite picture and updates the second local enlargement area in the display where the local selection frame is displayed and selected in the composite picture. It should be noted that, as the local selection frame moves in the synthesized picture, the second local enlargement area may be a local area of the target picture, or may be a local area that includes both the local area of the target picture and the local area of the mirror image picture. As shown in fig. 11b, a schematic diagram of the position of the local selection box relative to the composite picture is exemplarily given.

The embodiment of the application can ensure that the local selection frame continues to move towards the same direction after reaching the edge of the target picture along one direction, so that the effect similar to a panoramic picture is realized, the browsing efficiency can be improved, and the user experience is further improved. Meanwhile, the habit that people habitually browse along the same direction is considered, the embodiment of the application can ensure that the user always browses the pictures along the same direction, and the experience of the user is improved.

In some embodiments, if the candidate picture is a mirror picture or a composite picture. The mirror image picture of the target picture can be generated in advance, and the method specifically comprises the following steps:

carrying out mirror image processing on the target picture in response to a continuous moving instruction input by a user to obtain a mirror image picture; and the target picture and the mirror image picture are in an axial symmetry relationship along the direction indicated by the continuous moving instruction.

In some embodiments, the continuous move instruction may be configured to: the continuous moving instructions are a plurality of moving instructions used for indicating the local selection frames to move towards the same direction, and the number of the plurality of moving instructions in a fixed period exceeds a preset threshold value. In the embodiment of the present application, the preset threshold value in the fixed period is not limited, and may be, for example, more than 3 times within 1 s.

In some embodiments, the continuous move instruction may be configured to: the continuous movement instruction is a continuous movement instruction for instructing the local selection frame to continuously move towards one direction, and the duration of the continuous movement instruction exceeds a preset period. In the embodiment of the present application, the preset period is not limited, and for example, it may be determined that the continuous movement command is received when the long press exceeds 2 s. And when the time that the user presses the direction key on the remote controller for a long time exceeds a preset period, the controller generates a mirror image picture of the target picture.

It should be noted that, when the movement instruction input by the user satisfies the continuous movement instruction, it indicates that the user has low interest in the current first local zoom-in region and tends to view a subsequent portion of the target picture. Therefore, the controller can generate the mirror image picture in advance, so that when a user inputs an edge movement instruction subsequently, the candidate picture can be switched directly without generating the mirror image picture after the edge movement instruction is sent out, and the picture browsing efficiency is improved.

In some embodiments, the step of mirroring the target picture includes: and turning the target picture along the direction indicated by the continuous moving instruction to obtain a mirror image picture.

In some embodiments, if the candidate picture is a mirror picture or a composite picture. In consideration of the desirability of switching the target picture by the user, the mirror mode can be set.

Specifically, the display device further includes: and the mirror mode switch is configured to control the turning on and off of the mirror mode. The controller is further configured to: and responding to a mirror image mode starting instruction input by a user, starting a mirror image mode switch, and entering a mirror image mode.

When the mirror mode is turned on, the controller performs a pre-generation operation of a mirror image, and a processing step as in step 203. At this time, the user can always browse the target picture along the same direction. When the mirror mode is closed, the controller does not generate the mirror image picture, and when the local selection frame moves to the edge of the target picture, the user needs to control the local selection frame to move towards the opposite direction.

In the process of practical application, the corresponding relation between the mirror mode instruction and the remote controller key is bound in advance. For example, a mirror mode key 102 is added to the existing remote controller, as shown in fig. 7. When the user touches the key, the controller controls the display device to start the mirror image mode. When the user touches the key or the return key again, the controller controls the display device to close the mirror mode.

Step S301, if the local selection frame is located at the edge of the candidate picture, in response to an edge movement instruction for instructing the local selection frame to continue moving to the edge, switching the candidate picture to a second candidate picture, controlling the local selection frame to move along the direction indicated by the edge movement instruction relative to the second candidate picture, and updating and displaying an enlarged image of a third local enlarged area on the display.

In the embodiments of the present application, the third local enlargement area refers to: and selecting the area in the second candidate picture through the local selection frame.

After the target picture is switched to the candidate picture, the controller responds to a movement instruction of the local selection frame in the candidate picture, which is indicated by a user, controls the local selection frame to move relative to the candidate picture along the direction indicated by the movement instruction, and continuously updates and displays the enlarged image of the second local enlargement area in the display.

When the local selection frame is located at an edge of a side of the candidate picture, if the user continues to instruct the local selection frame to move towards the edge, that is, the user inputs an edge movement instruction, the controller needs to switch the candidate picture to the second candidate picture, so as to control the local selection frame to move towards the edge relative to the second candidate picture. At this time, the image selected by the local selection frame in the second candidate picture, that is, the image corresponding to the third locally enlarged region, is displayed in the display.

In some embodiments, if the candidate picture is a mirror picture of the target picture, the second candidate picture is the target picture. When the first local enlargement area of the target picture is displayed, the controller responds to the edge movement instruction and switches the target picture into a candidate picture, namely a mirror image picture of the target picture; when displaying the second local enlarged region of the candidate picture, the controller needs to switch the candidate picture to a mirror image of the candidate picture, i.e., a target picture, in response to the edge movement instruction.

In some embodiments, if the candidate picture is a composite picture, the second candidate picture is a second composite picture; the second composite picture is: and splicing the mirror image picture of the synthetic picture with the synthetic picture to obtain the picture. When the first local enlargement area of the target picture is displayed, the controller responds to the edge movement instruction and switches the target picture into a candidate picture, namely a composite picture; when the second local enlarged region of the candidate picture is displayed, the controller responds to the edge movement instruction, and needs to switch the candidate picture into a second synthetic picture, namely, a picture obtained by splicing a mirror image picture of the synthetic picture and the synthetic picture. It should be noted that, since the synthesized picture is formed by splicing the target picture and the mirror image picture, the synthesized picture is an axisymmetric picture, and therefore, the mirror image picture after the mirror image processing of the synthesized picture is also a synthesized picture. Namely, the second synthetic picture is also a picture obtained by splicing two synthetic pictures.
