FIG. 2 is a schematic flow chart of a method for controlling display of a picture according to an embodiment; as shown in fig. 2, the method for controlling display of pictures in this embodiment includes the following steps:
s11, in the initial mode of browsing pictures, if an operation instruction of the first key or the second key of the key device is received, entering a preset zoom mode.
In general, when a terminal device with a picture browsing function displays a picture in a default condition, the picture is displayed in a proper proportion according to the size of the screen of the terminal device, so that the picture can be completely displayed. Preferably, in the embodiment of the present invention, the default case is referred to as an initial mode. In the initial mode, the existing picture browsing function, for example, the function of turning up (previous picture) and turning down (next picture) of a picture, can be realized, but the picture cannot be zoomed or moved by physical keys, so that the picture details are difficult to be displayed.
S12, in the zooming mode, if an operation instruction of a first key or a second key of the key device is received, controlling the current picture to be zoomed in or zoomed out; if an operation instruction of a third key or a fourth key of the key equipment is received, entering a preset position adjustment mode;
in the zooming mode, the user can realize the zooming-in or zooming-out display of the picture through corresponding physical keys in the key device. For example: if an operation instruction of a first key of the key equipment is received, amplifying and displaying the current picture by taking the center point of the screen as the center; and if an operation instruction of a second key of the key equipment is received, reducing and displaying the current picture by taking the center point of the screen as the center.
Preferably, when the current picture is displayed in an enlarged/reduced manner with the center point of the screen as the center, the enlarged/reduced display may be performed according to a preset scaling value, for example, if the user presses the first key once, the current picture is enlarged to 120% with the center point of the screen as the center and displayed, and if the user presses the first key once again, the current picture is enlarged by 20% on the basis of the size of the current picture; or, if the user continuously presses the first key, the current picture can be continuously enlarged at an enlargement ratio of 20%. Similarly, if the user presses the second key once, the current picture is reduced to 80% of the size of the current picture by taking the center point of the screen as the center for display, and if the user presses the second key once again, the current picture is reduced by 20% on the basis of the size of the current picture; or, if the user continuously presses the first key, the current picture can be continuously reduced by 20%.
Preferably, the first key and the second key may be a direction up key and a direction down key in a key device, respectively. In the zooming mode, the image is controlled to be zoomed in by the direction up key, and the image is controlled to be zoomed out by the direction down key, so that the use habit of the user is met, and the user can conveniently master the image.
And S13, in the position adjustment mode, if an operation instruction of a first key, a second key, a third key or a fourth key of the key device is received, obtaining an adjustment direction corresponding to the current key according to a preset corresponding relation, and controlling the current picture to move according to the corresponding adjustment direction.
In the position adjusting mode, a user can display the picture in the vertical, horizontal and left directions through corresponding physical keys in the key equipment. For example: if an operation instruction of a third key of the key equipment is received, moving the whole current picture to the left side of the screen; if an operation instruction of a fourth key of the key equipment is received, moving the whole current picture to the right side of the screen; if an operation instruction of a first key of the key equipment is received, moving the whole current picture to the upper side of the screen; and if an operation instruction of a second key of the key equipment is received, moving the whole current picture to the lower part of the screen.
Preferably, when the current picture is displayed in a moving manner with the center point of the screen as the center, the position of the current picture can be moved according to a preset displacement amount, for example, if the user presses the first key once, the current picture is moved by 10cm above the screen, and if the user presses the first key once again, the current picture is moved by 10cm above the position of the current picture; or, if the user continuously presses the first key, the current picture can be continuously moved upwards according to the displacement of 10 cm. Similarly, if the user presses the second key once, the current picture is moved 10cm below the screen, and if the user presses the second key once again, the current picture is moved 10cm downwards on the basis of the position of the current picture; or, if the user continuously presses the second key, the current picture can be continuously moved downwards according to the displacement of 10 cm.
Preferably, the first key and the second key may be a direction up key and a direction down key in the key device, respectively, and the third key and the fourth key may be a direction left key and a direction right key, respectively. In the position adjusting mode, the picture is controlled to move upwards through the direction up key, the picture is controlled to move downwards through the direction down key, the picture is controlled to move leftwards through the direction left key, and the picture is controlled to move rightwards through the direction right key, so that the use habits of a user are met, and the user can conveniently master the picture.
In an embodiment, in the initial mode, the picture can be turned up and down according to physical key operations of the key device. Preferably, if an operation instruction of a third key or a fourth key of the key device is received, a previous picture or a next picture of the current picture is displayed. Specific examples thereof include: and in the initial mode, if an operation instruction of the direction left key of the key equipment is received, the next picture of the current picture is displayed, and if an operation instruction of the direction right key of the key equipment is received, the previous picture of the current picture is displayed.
Based on the display control method of the picture, when a user needs to check the local details of the picture, the picture is firstly amplified, namely the picture is taken as a trigger condition for entering a zooming mode through 'direction up' and 'direction down', so that the user can directly zoom the picture without special operation. Then, if the position of the picture detail to be checked by the user is not in the center of the screen, the position of the picture needs to be moved up, down, left and right, namely the left direction and the right direction are used as triggering conditions for entering a position adjusting mode, and therefore the position of the picture can be adjusted by the user without special operation; after entering the position adjustment mode, the picture can be adjusted in position up, down, left and right by the directions, so that the user can conveniently move the picture details to be viewed to the center of the display screen, and the function of browsing the picture details by using fewer physical keys is realized.
It can be understood that, in addition to the above-mentioned setting, the setting of the first key, the second key, the third key and the fourth key may also be set as physical keys included in other key devices, and only the first key, the second key, the third key and the fourth key need to be distinguishable from each other.
FIG. 3 is a diagram illustrating an embodiment of switching between display modes; that is, on the basis of the picture display control method of the above embodiment, the mutual switching among the initial mode, the zoom mode, and the position adjustment mode is further described, which is convenient for the user to autonomously switch among the three modes.
As shown in fig. 3, the switching between the various display modes includes:
and under the zooming mode, if an operation instruction of a first key or a second key of the key equipment is received, entering a preset zooming mode. In the zooming mode, if an operation instruction of a third key or a fourth key of the key equipment is received, entering a position adjusting mode; and if an operation instruction of a fifth key of the key equipment is received, returning to the initial mode. And in the position adjusting mode, if an operation instruction of a fifth key of the key equipment is received, returning to the initial mode.

In an embodiment, in the initial mode, if an operation instruction of a fifth key of the key device is received, the current mode is kept unchanged.
Preferably, corresponding switching prompts can be given in various display modes to guide the user to complete the mode switching.
Through the switching of the display modes, a user can freely switch among the three modes according to actual needs; the zooming and shifting of the picture can be easily realized only by 5 physical keys, namely, the browsing of the picture details is realized, and convenience is provided for a user to browse the picture on the terminal equipment.
Preferably, the first key and the second key are a direction up key and a direction down key respectively, the third key and the fourth key are a direction left key and a direction right key respectively, and the fifth key is a confirmation key. Correspondingly, the switching mode among the display modes comprises the following steps:

2) pressing a 'direction right' key to move the whole picture to the right side of the screen;
3) pressing the 'direction up' key to move the whole picture to the upper part of the screen;
4) pressing a 'direction down' key to move the whole picture to the lower part of the screen;
5) pressing a 'confirm' key, displaying the picture in a full screen according to the original proportion, and entering an 'original mode';
6) no operation is performed within a set time (e.g., within 1 second or 3 seconds), and the zoom mode is automatically entered.
Through the arrangement of the 5 keys, the switching among the modes and the browsing operation of the pictures are more in line with the use habits of the user, and the user can conveniently master the operation.
With reference to the above embodiments, the following describes an example of a method for controlling display of a picture according to the present invention by browsing the picture through a television. The set-top box is used as a display controller, the remote controller is used as key equipment, and the remote controller is communicated with the set-top box through infrared rays.
Selecting pictures to be browsed by using a remote controller, and displaying the pictures in a full screen according to an original proportion; thereafter, if the user wants to enlarge and display the image in the upper left corner, the following operations are required:
1: amplifying the picture according to the direction;
2: moving the image to the right integrally by pressing the direction to the right;
3: move the image to be enlarged (image in upper left corner) to the center of the screen by the "up, down, left, right" key;
4: waiting for 1S;
5: the image is enlarged in the "up" direction.
At this time, the detail information in the upper left corner of the picture can be displayed in an enlarged manner.
Furthermore, if the user wants to view the next picture, the following operations may be performed:
