When the user browses the image content through the mobile terminal, the image content is generally adapted to the display screen size of the mobile terminal, so that the mobile terminal can display all the image content. At this time, since the mobile terminal is usually small and the size of the display screen is limited, the image seen by the user is small, thereby affecting the sharpness of the image.

Although the user can also zoom in and view the image content, the zooming operation enlarges the image in both the horizontal direction and the vertical direction so that the image seen by the user is only a corner of the original image. When the user wants to see other parts of the original image, a slight swipe causes the image to move in both the horizontal and vertical directions, making it difficult for the user to find specific content in the image.

detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

The embodiment of the invention provides an image display method and device, which can at least solve the problem that the mobile terminal in the prior art is not clear enough when the image is displayed due to the small screen size, and when the image portion is displayed, the zoom operation is performed again. Moving the image in both the horizontal and vertical directions simultaneously makes it difficult for the user to find technical problems with specific content in the image.

FIG. 1 is a flowchart of an image display method according to an embodiment of the present invention. As shown in FIG. 1, the method includes the following steps:

Step S110: Acquire an image to be displayed.

Step S120: Acquire information of a display area corresponding to the image.

The display area may be an area for displaying an image preset on the display screen, and the size and position of the area may be flexibly set according to actual needs.

Step S130: The image is processed according to the information of the display area and the processed image is displayed in the display area. The size of the processed image in the first direction is the same as the size of the display area in the first direction, and the size of the processed image in the second direction is larger than the size of the display area in the second direction. And, the first direction is perpendicular to the second direction, for example, the first direction is a horizontal direction, and the second direction is a vertical direction; or the first direction is a vertical direction, and the second direction is a horizontal direction.

Wherein, when the corresponding sliding instruction is received, the displayed processed image is correspondingly slid in the second direction to display a partial image that is not displayed before the corresponding sliding instruction is received. The slide command can be implemented in various ways, for example, it can be the amount of sliding displacement input through the touch screen display, or it can be the amount of movement displacement of the display screen detected by the sensor. In a specific implementation, the displacement component of the sliding displacement amount or the movement displacement amount along the second direction is calculated, and the remaining content of the processed image is displayed according to the direction and magnitude of the displacement component.

Since the present invention is first adapted in one direction, in the process of sliding an image, the image can only slide in one direction, and does not slide up and down and left and right at the same time, so that the user can easily find the specific content in the image.

2 is a flow chart showing an image display method provided by an embodiment of the present invention. This embodiment is mainly applied to a scenario of home monitoring. For example, placing the camera in the living room of the user's home, aiming at the sofa in the middle of the living room, so as to capture the young children playing on the sofa, and transmit the captured video images to the parents' mobile devices so that parents can find them in time. Dangerous situation at home. Therefore, the original image in this embodiment is an image taken by the camera. In this embodiment, the original image needs to be displayed on a display screen of a mobile terminal (for example, a mobile phone or a tablet). As shown in FIG. 2, the method includes the following steps:

Step S210: setting the size and bit of the screen display area on the display screen of the mobile terminal in advance Set.

In this embodiment, the display screen is used not only for displaying images but also for displaying some control information. Therefore, it is necessary to previously set the screen display area for displaying an image and the size and position of the screen control area for displaying control information in accordance with the size of the display screen. For example, you can set a partial area of two-thirds of the top of the display to the screen display area, and set the remaining one-third of the local area below the display to the screen control area. Among them, the screen display area is all used to display an image, that is, the image fills the screen display area, leaving no blank portion on the edge. The control information displayed by the screen control area may include, but is not limited to, angle information of the camera, a button that controls the rotation direction of the camera, and/or a button that adjusts the sharpness of the camera, and the like.

A person skilled in the art can make various settings for the specific display mode of the screen display area and the screen control area according to actual needs, which is not limited by the present invention.

Step S220: The original image is scaled according to the size of the original image and the size of the screen display area, so that the size of the zoomed image (ie, the processed image) in the vertical direction is the same as the size of the screen display area in the vertical direction. And the size of the zoomed image in the horizontal direction is larger than the size of the screen display area in the horizontal direction.

In this step, the size of the original image and the size of the screen display area are first determined, and then the original image is adapted to the screen display area in one direction. For example, the size of the original image is 1280*720, and the size of the screen display area is 920*720, that is, the height 720 of the original image in the vertical direction is the same as the height 720 of the screen display area in the vertical direction, and the original image The width 1280 in the horizontal direction is greater than the width 920 of the screen display area in the horizontal direction. Therefore, when scaling the original image, the zoom ratio is set to 1:1, that is, the scaled image is the same size as the original image. For another example, the size of the original image is 1280*720, and the size of the screen display area is 1250*1080. In order to make the height 720 of the zoomed image in the vertical direction the same as the height 1080 of the screen display area in the vertical direction, it is necessary to The zoom ratio is set to 1.5:1. Therefore, the original image is magnified 1.5 times to obtain a zoom image having a size of 1920*1080, the height of the zoom image in the vertical direction is the same as the height of the screen display area in the vertical direction (both 1080), and the zoom The width 1920 of the image in the horizontal direction is greater than the width 1250 of the screen display area in the horizontal direction. In addition, when the scaling process is performed, in order to keep the aspect ratio of the image unchanged, it is preferable to make the scaling ratio of the image in the first direction the same as the scaling in the second direction.

In order to facilitate transmission, usually the image pixels taken by the camera are low. Therefore, if the zoom ratio is set to be large, the enlarged image will be very blurred; if the zoom ratio is set small, the reduced image will be more difficult to recognize. Therefore, in a preferred embodiment of the present invention, the screen display area is made the same size as the original image in the vertical direction, and thus the zoom ratio is 1:1. At this time, the scaled image is the original image, so that the sharpness can be ensured to the utmost extent, and the blur is not caused by the enlargement, and it is not easily recognized due to the reduction. Preferably, the size of the screen display area is not much different from the original image in the vertical direction, so that only the original image needs to be slightly scaled.

Step S230: Calculate a mapping relationship between the pixel position of the zoomed image and the photographing angle according to the wide angle parameter of the camera and the size of the zoomed image.

Since the camera has a certain imaging range, the captured image only includes the scene within the imaging range, but cannot be captured for scenes outside the imaging range. Therefore, the zoomed image contains exactly the scene within the camera's imaging range. According to the size of the zoomed image and the camera's imaging range, the specific pixel position on the zoomed image can be in one-to-one correspondence with the shooting angle of the camera.

For example, the shooting angle of the camera in the horizontal direction is 0-100 degrees, the shooting angle in the vertical direction is 0-90 degrees, and the size of the zoom image in the horizontal direction is 1280, and the size in the vertical direction is 720. The coordinate axis is created by taking the lower left corner of the zoomed image as the coordinate origin. The coordinates of the lower left corner of the zoomed image are (0,0), the coordinates of the lower right corner (1280,0), and the coordinates of the upper left corner are (0,720), the upper right corner. The coordinates are (1280, 720). Assume that the horizontal shooting angle corresponding to the pixel coordinates of the lower left corner of the zoom image is 0, the vertical shooting angle is also 0, and the horizontal shooting angle corresponding to the pixel coordinates of the lower right corner is (1280, 0). For 100, the vertical shooting angle is 0; accordingly, it can be determined that the pixel corresponding to the coordinate of (640, 0) corresponds to a horizontal shooting angle of 50 and a vertical shooting angle of zero. Suppose that the horizontal shooting angle corresponding to the pixel coordinate of the upper left corner of the zoom image is (0, 720) is 0, the vertical shooting angle is 90; the horizontal shooting angle corresponding to the pixel point of the upper right corner coordinate (1280, 720) is 100, the vertical shooting angle is 90; correspondingly, it can be determined that the pixel corresponding to the (640, 360) coordinate has a horizontal shooting angle of 50 and a vertical shooting angle of 45. And so on, each pixel on the scaled image can be associated with the camera's shooting angle.

Step S240: displaying the zoomed image in the screen display area; and determining a mapping relationship between the local pixel content displayed by the zoom image in the horizontal direction and the camera shooting angle, and The shooting angle corresponding to the local pixel content should be displayed.

Since the size (720) of the zoomed image in the vertical direction coincides with the size of the screen display area in the vertical direction, and the size of the zoomed image in the horizontal direction (1280) is larger than the size of the screen display area in the horizontal direction (920) ). Therefore, the pixel content of the scaled image in the vertical direction, that is, the pixel point of the vertical coordinate from 0 to 720 can be all displayed; and the pixel content of the scaled image in the horizontal direction, that is, the pixel point whose horizontal coordinate is from 0 to 1280 Cannot display all, only 920 pixels on the horizontal coordinate line can be displayed, and the remaining 360 pixels cannot be displayed.

For example, the image shown in FIG. 3a is a zoomed image, the black square in FIG. 3b is a screen display area, and the image in the black square is part of the scaled image displayed on the screen display area. Still assuming that the image size of FIG. 3a is 1280*720, and the coordinate system is established with the lower left corner of the image as the coordinate origin, it can be seen that the vertical coordinate range of the partial image displayed on the screen display area is 0-720, that is, The entire pixel content of the zoomed image is displayed in the vertical direction; the horizontal coordinate range of the partial image displayed on the screen display area is 200-1120, and the two parts of the pixel content whose horizontal coordinate is less than 200 and the horizontal coordinate is greater than 1120 are not displayed. Come out, that is, only the local pixel content of the scaled image is displayed in the horizontal direction.

In this example, when the processed image is displayed, the center of the image is aligned with the center of the display area. That is to say, the local pixel content displayed by the scaled image in the horizontal direction is the middle portion of the image, and the corresponding horizontal shooting angle range of the portion is 15.6 degrees-87.5 degrees. Therefore, the shooting angle corresponding to each pixel in the local pixel content can be correspondingly displayed in the screen control area, so that the user knows which part of the overall image the currently seen image is, and which angle images are not displayed. To be able to simulate the feeling of the real environment for the user. In this example, the middle portion of the image is displayed by default in the horizontal direction as an example. Since the person or object that the user pays attention to is usually located in the middle portion of the image, and the two sides of the image are often insignificant backgrounds, The middle portion of the image is displayed by default in step S240. Of course, the left side portion or the right side portion of the image may be displayed by default in the horizontal direction in step S240, or the display area in the horizontal direction may be determined according to the setting of the user.

Step S250: slid and display the remaining pixel content of the zoomed image in the horizontal direction in the screen display area according to the received sliding instruction; and determine a mapping relationship between the remaining pixel content and the camera shooting angle, and correspondingly display and the remaining pixel content. Corresponding shooting angle.

Among them, the sliding command can be issued in a variety of ways. For example, the slide command may be the amount of sliding displacement input through the touch screen display. At this time, the user only needs to slide the finger on the display screen, and the zoom image moves along the direction in which the user's finger slides, thereby displaying that the image is not displayed before. The rest of the pixel content. Alternatively, the sliding command may also be the amount of movement displacement of the display screen detected by the sensor. At this time, the user only needs to move the mobile phone in the horizontal direction to display the remaining pixel content of the zoomed image in the corresponding direction.

Specifically, when the remaining pixel content of the zoomed image is displayed in the horizontal direction in the screen display area, it is first necessary to calculate the displacement component of the sliding displacement amount or the moving displacement amount in the horizontal direction, and then slide according to the direction and size of the displacement component. Displays the remaining pixel content of the scaled image. For example, when the slide command is the amount of sliding displacement input through the touch screen display, if the user's finger slides horizontally 1 cm to the left, the zoom image will also move horizontally 1 cm to the left, thereby causing the portion displayed in the screen display area. The horizontal coordinate range of the image is changed to 201-1121; if the user's finger slides vertically upward, since the displacement component of the sliding displacement generated in the horizontal direction is 0, the zoomed image does not move, and the image displayed in the screen display area The content remains the same. Similarly, when the slide command is the movement displacement amount of the display screen detected by the sensor, if the user moves the mobile phone horizontally 1 cm to the left, the horizontal coordinate range of the partial image displayed in the screen display area is changed to 1991-1119. If the user moves the mobile phone vertically upward, since the displacement component of the generated displacement amount in the horizontal direction is 0, the image content displayed in the screen display area does not change.

In addition, when the zoom image is moved according to the sliding instruction, it is further determined whether the remaining portion of the zoom image in the direction to be displayed is smaller than the displacement amount in the sliding instruction, and if the determination result is yes, the zoom image is to be After the remaining portions of the displayed direction are all displayed, the sliding commands that are moved in this direction by the user are no longer responded to. For example, suppose that there is 1 cm left in the undisplayed portion on the left side of the zoom image, and if the zoom image needs to be moved 2 cm to the right according to the swipe command, then the zoom image needs to be moved 1 cm to the right, so that the left side of the zoom image is The remaining parts are all displayed, and if the user sends a slide instruction that needs to move the zoomed image to the right, the instruction is no longer responded to.

It can be seen that after receiving the sliding instruction, the image content displayed in the screen display area will only move in the horizontal direction, and no movement will occur in the vertical direction, thereby facilitating the user to find the specific content of interest. And, when the displayed image content is changed, displayed in the screen control area The imaging angle corresponding to the image content will also be changed accordingly, thereby enabling the user to know which part of the overall image the currently displayed image is, and providing a reference for the user to further slide the image in which direction.

In the above embodiment, the original image is adapted to the screen display area in the vertical direction to obtain a scaled image in which the vertical direction can be all displayed, and then the remaining portion of the scaled image is displayed by sliding in the horizontal direction. Specifically, when displaying an image, a series of operations such as decoding, rendering, and rendering are performed on the scaled image, wherein all pixel content in the scaled image has been rendered, and which part of the image is to be displayed is corresponding to the pixel content of the corresponding portion. To draw, when the part of the image to be displayed changes, the changed part of the pixel content is drawn accordingly.

The image in the above embodiment may be either a still image or a moving image, or may be a video composed of a plurality of consecutive images.

In addition, in other embodiments, the original image and the screen display area may be adapted in a horizontal direction to obtain a zoomed image that can be displayed in the horizontal direction, and then the zoomed image is displayed in a vertical direction by sliding. The rest. For example, assuming that the size of the original image is 720*5600, since the original image has a large size in the vertical direction, if it is adapted in the vertical direction, the image will be small and a blank will be left in the horizontal direction. Area, at this time, the original image and the screen display area can be adapted in the horizontal direction to obtain a scaled image that can be displayed in the horizontal direction, and then the rest of the scaled image is displayed by sliding in the vertical direction. In a specific implementation, the size ratio of the original image and the size ratio of the screen display area may be combined to determine in which direction the adaptation is performed.
