Detailed Description
Referring to fig. 1, fig. 1 is a flowchart illustrating a display method of a terminal according to an embodiment of the present disclosure. In this embodiment, the method includes:
101: the terminal receives a wake-up instruction for the display screen.
And the awakening instruction is used for indicating a display screen of the terminal to enter a working state from a dormant state. For example, when the terminal is in a standby black screen state, the terminal receives a signal of pressing a power key, that is, receives a wake-up instruction for the display screen. For another example, when the terminal waits for a black screen, the terminal receives a signal of pressing the home key, that is, receives a wake-up command for the display screen.
102: the terminal lightens a preset display area of the display screen to display a target image in the display area, and does not lighten the rest area of the display screen except the display area, wherein the target image is obtained by selecting a local shooting area for shooting, and the size of the target image is smaller than that of the display screen.
In this embodiment, when the terminal receives the wake-up command, the terminal can implement local display on the display screen. Specifically, the terminal is preset with a target image for displaying at a local position on the display screen and a display area of the target image on the display screen. The target image is obtained by selecting a local area of the shooting scene displayed on the display screen during shooting and shooting.
The display area is an area on the display screen for displaying the target image. In this embodiment, the display area is entirely used for displaying the target image, and of course, according to actual requirements, part of the display area may also be used for displaying the target image, and the rest of the display area is used for displaying contents set by other users. After the display area is set, the terminal may change the position and size of the display area. The preset display area is stored in association with the captured target image information.
Wherein the display area may be determined by the display coordinates. The display coordinates include coordinates of at least one point of the target image displayed on the display screen, for example, the display coordinates are coordinates of a center of the target image displayed on the display screen, and the display area may be an area having a size of the target image with the coordinates as a center; alternatively, the display coordinates may be coordinates of multiple points on the edge of the target image displayed on the display screen, and the display area may be an area formed by connecting the multiple points.
When the terminal receives a wake-up instruction, a display area is determined according to preset display coordinates, driving voltage is input to pixels of the display area so that the pixels on the display area obtain corresponding pixel values, the target image is displayed, and driving voltage is not input to the rest area of the display screen except the display area so that the rest area is not lightened.
In this embodiment, when the terminal receives the wake-up instruction, the terminal displays the target image in the local area of the display screen, and the remaining area of the display screen except the display area of the target image is not lighted, so that the local lighting display of the display screen is realized, and the electric energy is saved. And the target image displayed by the terminal is directly obtained by selecting a local shooting area for shooting, and later-stage cutting is not needed, so that the operation of a user is simplified.
Referring to fig. 2, fig. 2 is a flowchart illustrating a display method of a terminal according to another embodiment of the present disclosure. The method comprises the following steps:
201: the terminal obtains a target image by selecting a local shooting area for shooting, wherein the size of the target image is smaller than that of the display screen.
In this embodiment, the terminal acquires a target image for local display before local display, and specifically includes the following sub-steps:
a: when shooting, the terminal determines a local shooting area to be selected from a shooting scene displayed on the display screen according to coordinate information input by a user.
For example, as shown in fig. 3, when shooting, the camera of the terminal 300 or a camera connected to the terminal 300 captures light of an external shooting scene, and displays the external scene on the whole display screen 310 of the terminal after photoelectric conversion. The terminal acquires coordinate information input by the user and determines a local photographing region selected by the user in the photographing scene of the display screen 310, such as a circular region 311 shown in fig. 3, according to the coordinate information. It can be understood that the size of the local capture area is smaller than the capture scene displayed on the display screen, so that the size of the target image captured by the local capture area is smaller than the size of the display screen.
Wherein the coordinate information includes coordinates of at least three points of the edge of the local photographing region, so that the terminal can determine the shape and size of the local photographing region by obtaining the coordinates. For example, the terminal divides both the display screen and the touch screen into a certain number of points in a dot matrix form, where each point is usually a pixel, and the coordinates of the points of the touch screen of the display screen are in one-to-one correspondence. A user selects four points A, B, C and D shown in fig. 3 in a shooting scene displayed by a display screen during shooting, a terminal acquires coordinates (x 1, y 1), (x 2, y 2), (x 3, y 3) and (x 4, y 4) of the four points through a touch screen, and arc lines are supplemented in adjacent points of the four points to obtain a circular area 311 on the display screen; or the terminal supplements straight lines in adjacent points to obtain a display area; alternatively, the user does not select a partial point at the edge of the local imaging area, but directly circles the entire local imaging area on the display screen displaying the imaging scene, and the terminal directly specifies the local imaging area based on the coordinates of the area circled by the user. Therefore, the method for determining the local shooting area can be various, and is not limited herein, and the terminal can perform switching of different methods according to the user requirement.
b: and the terminal obtains the pixel data of the local shooting area and stores the pixel data to obtain the target image.
And after determining the local shooting area, the terminal acquires pixel data of the local shooting area of the shooting scene currently displayed on the display screen, and stores the acquired pixel data serving as pixel data of the target image in a local memory. The pixel data is pixel values of all pixels in the local shooting area. For example, when the terminal determines that the local photographing region is the circular region 311 shown in fig. 3, the RGB values of each pixel in the circular region 311 currently displayed on the display screen are acquired, and the target image is configured by the RGB values of each pixel of the circular region 311. The pixel data may also be image data in other formats in the corresponding pixels, such as RAW format, and the application is not limited thereto.
202: the terminal sets the target image according to setting information of at least one of size, color, shape and brightness of the target image input by a user, and sets a display area according to coordinate information of a display position of the target image input by the user.
After obtaining the target image according to 201 above, the terminal may reset at least one of the size, color, shape, brightness, and display area of the target image according to the setting information input by the user, and save the parameters as the target image. For example, as shown in fig. 4, the user performs an elongation operation on the target image 411 displayed on the display screen, and moves to the lower left to obtain a new target image 411'. After receiving a setting instruction of a user, the terminal acquires coordinate information of a target image displayed on a current display screen, and determines the shape and size of the target image and setting information of a display area. The setting information of the display area is display coordinate information of the target image, such as a center coordinate of the target image or a multi-point coordinate of an edge of the target image when the terminal wakes up and displays the target image.
It is understood that in other embodiments, the terminal may perform only setting of the target image according to the setting information of at least one of the size, color, shape, and brightness of the target image input by the user or only setting of the display region according to the setting information of the display position of the target image input by the user in this step.
203: the terminal receives a wake-up instruction for the display screen.
For example, when the terminal is in a black screen, the terminal receives a signal of pressing a power key or a home key, that is, receives a wake-up instruction for the display screen.
204: and the terminal displays the target image on the display area of the display screen according to preset display coordinates, displays the preset notification information of the application program on the target image, and does not lighten the rest area of the display screen except the display area.
And the terminal controls the display screen to enter a working state after receiving the awakening instruction. Specifically, the terminal determines a display area of the target image according to the display coordinates set in the above 202, or according to the display coordinates set in the above 202, the size and the shape of the target image, and inputs corresponding driving voltages to pixels in the display area of the display screen according to the color and the brightness of the target image, so that the pixels on the display area obtain corresponding pixel values, and then displays the target image. And the terminal does not input a driving voltage to the remaining area of the display screen except the display area where the target image is located, so that the remaining area is not lighted.
In this embodiment, the terminal presets an application program that needs to display its notification information when waking up, where the application program includes at least one of time, power, network signal, short message notification, and missed call, and it is understood that in other embodiments, the application program may also be other application programs that are needed by the user, such as incoming message notification of a social network site, unread mail notification, and the like. As shown in fig. 5, when the terminal displays the target image as described above, the current state information of the set application program is acquired, for example, the current time is 11. The display of the notification information of the application program on the target image can be according to the default display mode of the application program in the notification bar or the screen locking state of the terminal.
After the step 204 is executed, if the terminal receives the wake-up command, the terminal continues to execute 203 and 204.
In this embodiment, when the terminal receives the wake-up instruction, the terminal only displays the target image in the local area of the display screen, and the remaining area of the display screen except the display area of the target image is not lighted, so that the local lighting display of the display screen is realized, and the terminal can display the notification information of the application program on the target image, thereby enriching the display content of the local area, and enabling the user to obtain various information only through the local area.
It is understood that the terminal sets the target image and the display area according to the setting information according to the instruction input by the user, and in other embodiments, the terminal directly performs 201, 203, 204 if the user does not input the setting information. At this time, the display area is determined for initial display coordinate information default for the terminal.
Referring to fig. 6, fig. 6 is a schematic structural diagram of an embodiment of a display control device of a terminal according to the present application. In this embodiment, the apparatus includes a receiving module 610 and a control module 620.
The receiving module 610 is configured to receive a wake-up instruction for a display screen of the terminal, and send the wake-up instruction to the control module 620.
The awakening instruction is used for indicating a display screen of the terminal to enter a working state from a dormant state. For example, when the terminal is in a standby blank screen, the terminal receives a signal of pressing a power key, that is, receives a wake-up instruction for the display screen. For another example, when the terminal waits for a black screen, the terminal receives a signal of pressing a home key, that is, receives a wake-up instruction for the display screen.
The control module 620 is configured to illuminate a preset display area of the display screen to display a target image in the display area, and not illuminate the remaining area of the display screen except the display area, where the target image is obtained by selecting a local shooting area for shooting, and a size of the target image is smaller than a size of the display screen.
In this embodiment, the control module 620 can implement local display of the display screen when receiving the wake-up command. Specifically, the terminal is preset with a target image for displaying at a local position on the display screen and a display area of the target image on the display screen. The target image is obtained by shooting by selecting a local area of the shooting scene displayed on the display screen during shooting.
Wherein the display area may be determined by the display coordinates. The display coordinates include coordinates of at least one point of the target image displayed on the display screen, for example, the display coordinates are coordinates of a center of the target image displayed on the display screen, and the display area may be an area having a size of the target image with the coordinates as a center; alternatively, the display coordinates may be coordinates of edge multiple points of the target image displayed on the display screen, and the display area may be an area formed by connecting the multiple point coordinates.
When receiving the wake-up instruction, the control module 620 determines a display area according to preset display coordinates, and inputs a driving voltage for a pixel of the display area so as to enable the pixel on the display area to obtain a corresponding pixel value, and further displays the target image, without inputting a driving voltage to a remaining area of the display screen except the display area, so as to enable the remaining area not to be lit.
In this embodiment, when the display control device of the terminal receives the wake-up instruction, the target image is displayed in the local area of the display screen, and the remaining area of the display screen except the display area of the target image is not lighted, so that the local lighting display of the display screen is realized, and the electric energy is saved. And the target image displayed by the terminal is directly obtained by selecting a local shooting area for shooting, and later-stage cutting is not needed, so that the operation of a user is simplified.
Referring to fig. 7, fig. 7 is a diagram illustrating another embodiment of a display control apparatus of a terminal according to the present application. Different from the previous embodiment, the display control apparatus further includes a shooting module 730 and a setting module 740, wherein the receiving module 710 and the control module 720 of the display control apparatus are as the receiving module 610 and the control module 620 in the previous embodiment, which are not described herein again.
The shooting module 730 is configured to obtain a target image by shooting a selected local shooting area, where a size of the target image is smaller than a size of the display screen.
In this embodiment, the shooting module 730 is specifically configured to:
a: when shooting, the terminal determines a local shooting area to be selected from a shooting scene displayed on the display screen according to coordinate information input by a user.
For example, as shown in fig. 3, when shooting, the camera of the terminal 300 or a camera connected to the terminal 300 captures light of an external shooting scene, and displays the external scene on the whole display screen 310 of the terminal after photoelectric conversion. The terminal acquires coordinate information input by the user and determines a local photographing region selected by the user in the photographing scene of the display screen 310, such as a circular region 311 shown in fig. 3, according to the coordinate information. It can be understood that the size of the local capture area is smaller than the capture scene displayed on the display screen, so that the size of the target image captured by the local capture area is smaller than the size of the display screen.
Wherein the coordinate information includes coordinates of at least three points of the edge of the local photographing region, so that the terminal can determine the shape and size of the local photographing region by obtaining the coordinates. Specifically, the obtaining of the coordinate information is described in the display method of the terminal, and is not described herein again.
b: and the terminal obtains the pixel data of the local shooting area and stores the pixel data to obtain the target image.
And after determining the local shooting area, the terminal acquires pixel data of the local shooting area of the shooting scene currently displayed on the display screen, and stores the acquired pixel data serving as pixel data of the target image in a local memory. The pixel data is pixel values of all pixels in the local shooting area.

After obtaining the target image according to the photographing module 730, the setting module 740 may reset at least one of a size, a color, a shape, a brightness, and a display area of the target image according to the setting information input by the user, and save the parameter as the target image. The setting information of the display area is display coordinate information of the target image, such as a center coordinate of the target image or a multi-point coordinate of an edge of the target image when the terminal wakes up and displays the target image.
It is understood that, in other embodiments, the setting module 740 may perform only setting of the target image according to the setting information of at least one of the size, color, shape, and brightness of the target image input by the user, or only setting of the display region according to the setting information of the display position of the target image input by the user.
Optionally, the control module 720 is specifically configured to display the target image on the display area of the display screen according to preset display coordinates, and display the notification information of the preset application program on the target image, and not light up the remaining area of the display screen except the display area.
The control module 720 controls the display screen to enter the working state after receiving the wake-up command. Specifically, the control module 720 determines a display area of the target image according to the display coordinates set by the setting module 740 or according to the display coordinates set by the setting module 740, the size and the shape of the target image, and inputs corresponding driving voltages to pixels in the display area of the display screen according to the color and the brightness of the target image, so that the pixels on the display area obtain corresponding pixel values, and then displays the target image. And, the control module 720 does not input the driving voltage to the remaining region of the display screen except for the display region where the target image is located, so that the remaining region is not lit.
The control module 720 presets an application program that needs to display notification information when waking up, where the application program includes at least one of time, power, network signal, short message notification, and missed call, and it is understood that in other embodiments, the application program may also be other application programs that are needed by the user, such as incoming message notification of a social network site, unread mail notification, and the like. As shown in fig. 5, when the control module 720 displays the target image as described above, the set current state information of the application program is acquired, for example, the current time is 11, there is an unread message, and the acquired current state information of the application program is further displayed on the target image 511. The display of the notification information of the application program on the target image can be according to the default display mode of the application program on the notification bar or the screen locking.
In this embodiment, when the display control device of the terminal receives the wake-up instruction, the target image is displayed only in the local area of the display screen, and the remaining area of the display screen except the display area of the target image is not lit, so that the local lit display of the display screen is realized, and the terminal can display the notification information of the application program on the target image, thereby enriching the display content of the local area, and enabling the user to obtain various information only through the local area.
It is understood that in other embodiments, the terminal may not include the setup module described above. At this time, the display area is determined for initial display coordinate information default for the terminal.
