The embodiment of the invention provides a picture display method and a user terminal, wherein the user terminal can adjust the display resolution of the user terminal according to pixel point information of a target picture, so that the problem of poor display effect caused by mismatching of the pixel point information of the target picture and the display resolution of the user terminal can be solved. Therefore, the image display effect can be improved by implementing the embodiment of the invention.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a picture display method according to an embodiment of the present invention. The method shown in fig. 1 may be applied to user terminals such as smart phones (e.g., Android phones, iOS phones, etc.), tablet computers, palmtop computers, Mobile Internet Devices (MID), PADs, etc. As shown in fig. 1, the picture display method may include the steps of:
s101, obtaining pixel point information of the target picture.
In the embodiment of the present invention, the target picture may be a picture stored in the user terminal by the user, or may be a picture taken by the user at this time by using a shooting application of the user terminal.
In the embodiment of the invention, the pictures are all composed of the arranged pixel points. Therefore, when the feature of a picture is to be described, it is possible to describe the information of the pixel points constituting the picture.
S102, according to the mapping relation between the pre-stored picture pixel point information and the display resolution, the display resolution of the user terminal is adjusted to be matched with the pixel point information of the target picture.
In the embodiment of the invention, the mapping relation between the picture pixel point information and the display resolution can be stored in the user terminal in advance. The mapping relation between the picture pixel point information and the display resolution comprises that when the picture pixel point information is different, the display resolutions of the corresponding user terminals are different. And because the hardware information of different user terminals is different, the concrete representation form of the mapping relation is different when the mapping relation is used for different user terminals.
And S103, displaying the target picture at the adjusted display resolution.
In the embodiment of the invention, after the user terminal adjusts the display resolution of the user terminal to the resolution matched with the pixel point information of the target picture according to the mapping relation between the pre-stored picture pixel point information and the display resolution, the user terminal can display the target picture through the adjusted display resolution.
In fig. 1, a user terminal first obtains pixel point information of a target picture; according to the mapping relation between the pre-stored picture pixel point information and the display resolution, the display resolution of the user terminal is adjusted to the resolution matched with the pixel point information of the target picture; and displaying the target picture at the adjusted display resolution. In the embodiment of the invention, the user terminal can adjust the display resolution of the user terminal according to the pixel point information of the target picture, so that the problem of poor display effect caused by mismatching of the pixel point information of the target picture and the display resolution of the user terminal can be solved. Therefore, the image display effect can be improved by implementing the embodiment of the invention.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating another picture display method according to an embodiment of the invention. As shown in fig. 2, the picture display method may include the steps of:
s201, obtaining pixel point information of the target picture.
In the embodiment of the invention, the pixel point information of the target picture comprises the number of the pixel points of the target picture and the coordinates of the pixel points of the target picture.
In the embodiment of the invention, because the pixel point is the basic unit of the digital picture, the characteristic information of the picture can be known by knowing the pixel point information of the target picture. That is, the number of the target picture pixel points and the coordinates of the target picture pixel points are known. The total amount of the pixel points of the bitmap picture in the height direction and the width direction is called the pixel size of the picture, the pixel size of the same picture is fixed, the more the pixel points are, the finer and more natural the picture is, but the larger the picture is. The pixel size is related to the resolution, the smaller the resolution, the larger the pixel size. Each pixel is assigned a color value. The high resolution pictures contain more pixels than the low resolution pictures and therefore the pixel points are smaller. A high resolution picture can reproduce more details and finer color transitions than a low resolution picture because of the higher pixel density in the high resolution picture.
In this embodiment of the present invention, before performing step S201, the following steps may be further included:
21) when receiving a picture display instruction triggered by a user operating a target key, outputting prompt information for prompting the input of information to be verified;
22) when receiving information to be verified input in response to the prompt message, verifying whether the information to be verified is consistent with preset verification information;
23) and if the information to be verified is verified to be consistent with the preset verification information, executing the step of obtaining the pixel point information of the target picture.
In the embodiment of the invention, after the user terminal receives the picture display instruction triggered by the operation of the target key by the user, the user terminal outputs prompt information for prompting the input of information to be verified; and the user terminal may output a to-be-authenticated information input port for inputting the to-be-authenticated information.
In the embodiment of the present invention, the information to be verified may include, but is not limited to, any one or combination of a password to be verified, fingerprint information to be verified, face information to be verified, iris information to be verified, retina information to be verified, and voiceprint information to be verified.
In the embodiment of the present invention, the preset verification information may include, but is not limited to, any one or combination of a preset verification password, preset verification fingerprint information, preset verification face information, preset verification iris information, preset verification retina information, and preset verification voiceprint information.
In an embodiment of the present invention, the preset verification information may include fingerprint string information and an input time corresponding to each fingerprint; accordingly, verifying whether the information to be verified is consistent with the preset verification information may include the steps of:
verifying whether the fingerprint string is the same as the fingerprint string included in the preset verification information and whether the difference of the input time of the same fingerprint is smaller than a preset value, and if the fingerprint string is the same as the fingerprint string included in the preset verification information and the difference of the input time of the same fingerprint is smaller than the preset value, verifying that the information to be verified is consistent with the preset verification information; otherwise, the information to be verified is inconsistent with the preset verification information. By implementing the implementation mode, the picture can be prevented from being checked on the user terminal by an illegal user, so that the terminal can be effectively prevented from being operated by the illegal user.
S202, determining distribution information of pixel points in the target picture according to the coordinates of the pixel points of the target picture.
In the embodiment of the invention, the user terminal can determine the distribution information of the pixel points in the target picture according to the coordinates of the pixel points of the target picture. That is, the user terminal can determine the distribution of the pixel points in the target picture according to the coordinates of the pixel points in the target picture, and can clearly identify the pixel points in the target picture at the positions with a large number and the local pixel points with a small number. Due to the places with large number of pixel points, the picture display is clearer.
S203, dividing the target picture into at least two sub-pictures according to the distribution information of the pixel points in the target picture, and dividing the display area of the user terminal into at least two display areas.
In the embodiment of the invention, when the user terminal divides the target picture into at least two sub-pictures according to the distribution information of the pixel points in the target picture, the display area of the user terminal is divided into at least two display areas, wherein each display area is used for displaying one sub-picture. That is, when the target picture is divided into N sub-pictures according to the distribution information of the pixel points in the target picture, the display area of the user terminal is divided into N display areas in the same dividing manner, and each display area is used for displaying one sub-picture.
For example, when the target picture is divided into 4 sub-pictures according to the distribution information of the pixel points in the target picture, the display area of the user terminal is divided into 4 display areas in the same dividing manner, wherein each display area is used for displaying one sub-picture. As an optional implementation manner, the display area of the user terminal is divided into 4 display areas, and the target picture is divided into 4 sub-pictures in one-to-one correspondence with the distribution information of the pixel points in the target picture. That is, as shown in fig. 2a, fig. 2a is a schematic diagram of dividing a picture according to an embodiment of the present invention, and as shown in fig. 2b, fig. 2b is a schematic diagram of dividing a display area according to an embodiment of the present invention. The sub-picture labeled one in fig. 2a corresponds to the display area labeled one in fig. 2 b. That is, the display area labeled one in fig. 2b is used to display the sub-picture labeled one in fig. 2 a; the display area labeled two in fig. 2b is used for displaying the sub-picture labeled two in fig. 2 a; the display area labeled three in fig. 2b is used for displaying the sub-picture labeled three in fig. 2 a; the display area labeled four in fig. 2b is used to display the sub-picture labeled four in fig. 2 a.
As another alternative, the user terminal divides the display area and the target picture into the sub-images according to the distribution information of the pixel points, and the number of the final divisions is the same, but it is not always necessary to have a strict one-to-one correspondence. That is, the one-labeled display region in fig. 2b can be used to display the one-labeled sub-picture in fig. 2 a; the display area labeled one in fig. 2b can also be used to display the sub-picture labeled two in fig. 2 a; the display area labeled one in fig. 2b is used to display the sub-picture labeled three in fig. 2a, and so on. The correspondence between other display areas and sub-pictures can be analogized.
As another alternative embodiment, the shape of the target picture dividing sub-picture may be a regular picture or an irregular picture, which is not limited in the present invention.
And S204, determining the number of pixel points in each sub-picture in the divided target picture.
In the embodiment of the invention, the higher the number of the pixel points of the picture is, the clearer the picture is displayed, and in the same picture, the number of the possible pixel points in different areas is different. Therefore, it is particularly important to determine the number of pixel points in each sub-picture in the divided target picture.
S205, adjusting the resolution of each display area according to the mapping relation between the number of the picture pixel points stored in advance and the display resolution.
In the embodiment of the invention, the adjusted resolution of each display area corresponds to the number of pixel points of the sub-picture displayed in the display area. For example, when the display area labeled one in FIG. 2b is used to display the sub-picture labeled one in FIG. 2 a; the display area labeled two in fig. 2b is used for displaying the sub-picture labeled two in fig. 2 a; the display area labeled three in fig. 2b is used for displaying the sub-picture labeled three in fig. 2 a; the display area labeled four in fig. 2b is used to display the sub-picture labeled four in fig. 2 a. The display area labeled one in fig. 2b corresponds to the number of pixels of the sub-picture labeled one in fig. 2 a; the display area labeled two in fig. 2b corresponds to the number of pixels of the sub-picture labeled two in fig. 2 a; the display area labeled three in fig. 2b corresponds to the number of pixel points of the sub-picture labeled three in fig. 2 a; the four numbered display regions in fig. 2b correspond to the four numbered sub-pictures of fig. 2a in terms of the number of pixels.
And S206, displaying the divided target picture with the adjusted display resolution.
And S207, when an exit instruction for exiting the application program corresponding to the display picture, which is input by the user, is received, adjusting the display resolution of the user terminal to the default resolution of the system.
In the embodiment of the invention, the user terminals all have a system default resolution, and when an exit instruction which is input by a user and aims at exiting an application program corresponding to a display picture is received, the display resolution of the user terminals is adjusted to the system default resolution.
In fig. 2, the user terminal divides the target picture into at least two sub-pictures according to the distribution information of the pixel points in the target picture, and divides the display area of the user terminal into at least two display areas; and adjusting the resolution of each display area according to the mapping relation between the number of the prestored picture pixel points and the display resolution. Therefore, the embodiment of the invention can still improve the picture display effect.

A second determining module 3022, configured to determine the number of pixel points in each sub-picture in the target picture divided by the dividing module 3021.
The adjusting module 3023 is configured to adjust the resolution of each display region according to a mapping relationship between the number of the pre-stored pixel points of the picture and the display resolution, where the adjusted resolution of each display region corresponds to the number of the pixel points of the sub-picture displayed in the display region.
In this embodiment of the present invention, the first determining module 3020 may determine distribution information of pixel points in the target picture according to coordinates of pixel points of the target picture. That is, the first determining module 3020 may determine the distribution of the pixel points in the target picture according to the coordinates of the pixel points in the target picture, and may clearly identify which position pixel points are more and which local pixel points are less in the target picture. Due to the places with large number of pixel points, the picture display is clearer.
In this embodiment of the present invention, when the dividing module 3021 divides the target picture into at least two sub-pictures according to the distribution information of the pixel points in the target picture, the display area of the user terminal is divided into at least two display areas, where each display area is used for displaying one sub-picture. That is, when the dividing module 3021 divides the target picture into N sub-pictures according to the distribution information of the pixel points in the target picture, the display area of the user terminal is divided into N display areas in the same dividing manner, and each display area is used for displaying one sub-picture.
For example, when the dividing module 3021 divides the target picture into 4 sub-pictures according to the distribution information of the pixel points in the target picture, the same dividing manner is adopted to divide the display area of the user terminal into 4 display areas, where each display area is used for displaying one sub-picture. As an optional implementation manner, the display area of the user terminal is divided into 4 display areas, and the target picture is divided into 4 sub-pictures in one-to-one correspondence with the distribution information of the pixel points in the target picture. That is, as shown in fig. 2a, fig. 2a is a schematic diagram of dividing a picture according to an embodiment of the present invention, and as shown in fig. 2b, fig. 2b is a schematic diagram of dividing a display area according to an embodiment of the present invention. The sub-picture labeled one in fig. 2a corresponds to the display area labeled one in fig. 2 b. That is, the display area labeled one in fig. 2b is used to display the sub-picture labeled one in fig. 2 a; the display area labeled two in fig. 2b is used for displaying the sub-picture labeled two in fig. 2 a; the display area labeled three in fig. 2b is used for displaying the sub-picture labeled three in fig. 2 a; the display area labeled four in fig. 2b is used to display the sub-picture labeled four in fig. 2 a.
As another alternative, the user terminal divides the display area and the target picture into the sub-images according to the distribution information of the pixel points, and the number of the final divisions is the same, but it is not always necessary to have a strict one-to-one correspondence. That is, the one-labeled display region in fig. 2b can be used to display the one-labeled sub-picture in fig. 2 a; the display area labeled one in fig. 2b can also be used to display the sub-picture labeled two in fig. 2 a; the display area labeled one in fig. 2b is used to display the sub-picture labeled three in fig. 2a, and so on. The correspondence between other display areas and sub-pictures can be analogized.
As another alternative embodiment, the shape of the target picture dividing sub-picture may be a regular picture or an irregular picture, which is not limited in the present invention.
In the embodiment of the invention, the adjusted resolution of each display area corresponds to the number of pixel points of the sub-picture displayed in the display area. For example, when the display area labeled one in FIG. 2b is used to display the sub-picture labeled one in FIG. 2 a; the display area labeled two in fig. 2b is used for displaying the sub-picture labeled two in fig. 2 a; the display area labeled three in fig. 2b is used for displaying the sub-picture labeled three in fig. 2 a; the display area labeled four in fig. 2b is used to display the sub-picture labeled four in fig. 2 a. The display area labeled one in fig. 2b corresponds to the number of pixels of the sub-picture labeled one in fig. 2 a; the display area labeled two in fig. 2b corresponds to the number of pixels of the sub-picture labeled two in fig. 2 a; the display area labeled three in fig. 2b corresponds to the number of pixel points of the sub-picture labeled three in fig. 2 a; the four numbered display regions in fig. 2b correspond to the four numbered sub-pictures of fig. 2a in terms of the number of pixels.
In fig. 4, it is described in detail that the dividing module 3021 divides the target picture into at least two sub-pictures according to the distribution information of the pixel points in the target picture, and the adjusting module 3023 divides the display area of the user terminal into at least two display areas; and adjusting the resolution of each display area according to the mapping relation between the number of the prestored picture pixel points and the display resolution. Therefore, the embodiment of the invention can still improve the picture display effect.
