Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

The embodiment of the present 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 when all the images are displayed due to the small screen size. The technical problem of making the image move both horizontally and vertically, making it difficult for users to find specific content in the image.

FIG. 1 shows a flowchart of an image display method provided by an embodiment of the present invention. As shown in Figure 1, the method includes the following steps:

Step S110: Obtain an image to be displayed.

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

Wherein, the display area can be a pre-set area on the display screen for displaying images, and the size and position of this area can be flexibly set according to actual needs.

Step S130: Process the image according to the information of the display area and display the processed image in the display area. Wherein, 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. Moreover, 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 a corresponding sliding instruction is received, the displayed processed image slides correspondingly in the second direction to display a part of the image that was not displayed before receiving the corresponding sliding instruction. The slide command can be implemented in various ways, for example, it can be a sliding displacement input through a touch screen, or it can be a movement displacement of the display screen detected by a sensor. During specific implementation, the above-mentioned sliding displacement or the displacement component of the moving displacement along the second direction is calculated, and the rest of the processed image is displayed in a sliding manner according to the direction and size of the displacement component.

Because the adaptation is performed in one direction first in the present invention, the image can only slide in one direction during the process of sliding the image, instead of sliding up, down, left, and right simultaneously, so users can easily find specific content in the image.

Fig. 2 shows a flowchart of an image display method provided by a specific embodiment of the present invention. This embodiment is mainly used in home monitoring scenarios. For example, the camera is placed in the living room of the user's home, aimed at the sofa in the middle of the living room, so as to capture young children playing on the sofa, and transmit the captured video images. to parents' mobile devices, so that parents can discover dangerous situations at home in time. Therefore, the original image in this embodiment is an image captured by a camera, and in this embodiment, the original image needs to be displayed on a display screen of a mobile terminal (such as a mobile phone or a tablet computer). As shown in Figure 2, the method includes the following steps:

Step S210: pre-set the size and position of the screen display area on the display screen of the mobile terminal.

In this embodiment, the display screen is not only used to display images, but also used to display some control information. Therefore, the size and position of the screen display area for displaying images and the screen control area for displaying control information need to be preset according to the size of the display screen. For example, the upper two-thirds of the partial area of the display screen can be set as the screen display area, and the remaining one-third of the local area below the display screen can be set as the screen control area. Wherein, the display area of the screen is entirely used for displaying images, that is, the image occupies the display area of the screen so that no blank portion is left at the edge thereof. The control information displayed in the screen control area may include but not limited to: angle information of the camera, buttons for controlling the rotation direction of the camera and/or adjusting the definition of the camera, and the like.

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

Step S220: Scale the original image according to the size of the original image and the size of the screen display area, so that the vertical size of the zoomed image (i.e. the processed image) is the same as the vertical size of the screen display area , and the size of the scaled 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 must be determined first, and then the original image and the screen display area are adapted 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 in the horizontal direction of the screen display area. Therefore, when scaling the original image, the scaling ratio is set to 1:1, that is, the size of the scaled image is the same as that of the original image. As 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 vertical height 720 of the scaled image the same as the vertical height 1080 of the screen display area, it is necessary to set The zoom ratio is set to 1.5:1, therefore, the original image is enlarged by 1.5 times to obtain a zoomed image with a size of 1920*1080, and the height of the zoomed image in the vertical direction is the same as the height of the screen display area in the vertical direction ( Both are 1080), and the horizontal width 1920 of the zoomed image is greater than the horizontal width 1250 of the screen display area. In addition, when performing the scaling process, in order to keep the aspect ratio of the image unchanged, preferably, the scaling ratio of the image in the first direction is the same as that in the second direction.

In order to facilitate transmission, the pixels of the image captured by the camera are generally low. Therefore, if the zoom ratio is set to a large value, the enlarged image will be very blurred; and if the zoom ratio is set to a small value, the reduced image will be blurred less recognizable. Therefore, in a preferred embodiment of the present invention, the size of the screen display area is the same as that of the original image in the vertical direction, so the zoom ratio is 1:1. At this time, the zoomed image is the original image, so that the maximum Guaranteed clarity, neither blurring due to zoom-in, nor difficult to identify due to zoom-out. Preferably, the vertical size of the screen display area and the original image is not much different, so the original image only needs to be slightly scaled.

Step S230: According to the wide-angle parameter of the camera and the size of the zoomed image, calculate the mapping relationship between the pixel position of the zoomed image and the shooting angle.

Since the camera has a certain camera range, the images it captures only include the scenes within the camera range, but cannot capture the scenes outside the camera range. Therefore, the zoomed image just includes the scene within the shooting range of the camera, and according to the size of the zoomed image and the shooting range of the camera, the specific pixel positions on the zoomed image can be one-to-one corresponding to the shooting angle of the camera.

For example, the shooting angle of the camera in the horizontal direction is 0-100 degrees, and the shooting angle in the vertical direction is 0-90 degrees, and the size of the zoomed image in the horizontal direction is 1280, and the size in the vertical direction is 720. The coordinate axis is established with the lower left corner of the zoomed image as the coordinate origin, then the coordinates of the lower left corner of the zoomed image are (0, 0), the coordinates of the lower right corner are (1280, 0), the coordinates of the upper left corner are (0, 720), and the upper right corner The coordinates of are (1280, 720). Assume that the horizontal shooting angle corresponding to the pixel point whose coordinates are (0, 0) in the lower left corner of the zoomed image is 0, and the vertical shooting angle is also 0; the horizontal shooting angle corresponding to the pixel point whose coordinates are (1280, 0) in the lower right corner is 100, and the vertical shooting angle is 0; correspondingly, it can be determined that the horizontal shooting angle corresponding to the pixel point with coordinates (640, 0) is 50, and the vertical shooting angle is 0. Assume that the horizontal shooting angle corresponding to the pixel with coordinates (0, 720) in the upper left corner of the zoomed image is 0, and the vertical shooting angle is 90; the horizontal shooting angle corresponding to the pixel with the coordinates in the upper right corner (1280, 720) is 100, and the vertical shooting angle is 90; correspondingly, it can be determined that the horizontal shooting angle corresponding to the pixel point with coordinates (640, 360) is 50, and the vertical shooting angle is 45. By analogy, each pixel on the zoomed image can be corresponded one-to-one with the shooting angle of the camera.

Step S240: Display the zoomed image in the screen display area; and determine the mapping relationship between the local pixel content displayed in the horizontal direction of the zoomed image and the shooting angle of the camera, and correspondingly display the shooting angle corresponding to the local pixel content.

Since the vertical size (720) of the zoomed image is consistent with the vertical size of the screen display area, and the horizontal size (1280) of the zoomed image is larger than the horizontal size (920) of the screen display area ), therefore, the pixel content of the zoomed image in the vertical direction, that is, the pixels with vertical coordinates from 0 to 720 can be displayed in full; and the pixel content of the zoomed image in the horizontal direction, that is, the pixels with horizontal coordinates from 0 to 1280 All points cannot be displayed, 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, and the black box in FIG. 3b is a screen display area, and the image in the black box is part of the zoomed image displayed on the screen display area. Still assuming that the size of the image in Figure 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 part of the image displayed on the screen display area is 0-720, namely The entire pixel content of the scaled image is displayed in the vertical direction; the horizontal coordinate range of the part of the image displayed on the screen display area is 200-1120, while the two parts of the pixel content with the horizontal coordinate less than 200 and the horizontal coordinate greater than 1120 are not displayed out, that is, only the local pixel content of the scaled image is displayed in the horizontal direction.

In this example, when displaying the processed image, align the center of the image with the center of the display area. That is to say, the local pixel content displayed in the horizontal direction of the zoomed image is the middle part of the image, and the corresponding horizontal shooting angle range of this part is 15.6 degrees-87.5 degrees. Therefore, this part can be displayed in the screen control area The shooting angle corresponding to each pixel in the pixel content, so that the user can understand which part of the overall image the image currently seeing is, and which angles of the image are not displayed, so that the user can simulate the feeling of the real environment. In this example, the middle part of the image is displayed by default in the horizontal direction as an example. Usually, the person or object that the user pays attention to is often located in the middle part of the image, and the two sides of the image are often some irrelevant backgrounds, so In step S240, the middle part of the image is displayed by default. Certainly, in step S240, the left part or the right part of the image may also be displayed by default in the horizontal direction, or the display area in the horizontal direction may also be determined according to user settings.

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

Wherein, the sliding instruction can be issued in various ways. For example, the slide command can be a slide displacement input through a touch screen. At this time, the user only needs to slide his finger on the screen, and the zoomed image will move along the direction of the slide of the user's finger, thereby displaying the image that was not displayed before. the rest of the pixel content. Alternatively, the sliding command may also be the 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 sliding and displaying the remaining pixel content of the zoomed image in the screen display area along the horizontal direction, it is first necessary to calculate the above-mentioned sliding displacement or the displacement component of the moving displacement along 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 sliding command is the sliding displacement input through the touch screen, if the user slides his finger horizontally to the left by 1 cm, the zoomed image will also move horizontally to the left by 1 cm, so that the part displayed in the screen display area The horizontal coordinate range of the image is changed to 201-1121; if the user slides his finger vertically upwards, since the displacement component of the sliding displacement generated by it in the horizontal direction is 0, the zoomed image does not move, and the image displayed in the screen display area The content remains unchanged. Similarly, when the sliding command is the movement displacement of the display screen detected by the sensor, if the user moves the mobile phone horizontally to the left by 1 cm, the horizontal coordinate range of some images displayed in the screen display area will be changed to 199-1119 ; If the user moves the mobile phone vertically upwards, since the displacement component of the generated displacement in the horizontal direction is 0, the image content displayed in the screen display area remains unchanged.

In addition, when moving the zoomed image according to the slide command, it is necessary to further judge whether the remaining part of the zoomed image in the direction to be displayed is smaller than the displacement in the slide command. After all the remaining parts in the direction are displayed, it will no longer respond to the sliding command input by the user to move in this direction. For example, suppose there is 1 cm left on the left side of the zoomed image, and the zoomed image needs to be moved to the right by 2 cm according to the sliding command. At this time, it is only necessary to move the zoomed image to the right by 1 cm to make the left part of the zoomed image All the parts of the image can be displayed. If at this time a sliding command to move the zoomed image to the right is further received from the user, the command will no longer be 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 will not move in the vertical direction, so that it is convenient for the user to find the specific content concerned. Moreover, when the displayed image content is changed, the camera angle corresponding to the image content displayed in the screen control area will also be changed accordingly, so that the user can know which part of the overall image the currently displayed image is, It provides 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 zoomed image that can be fully displayed in the vertical direction, and then the rest of the zoomed image is displayed in the horizontal direction by sliding. Specifically, when displaying an image, it is necessary to perform a series of operations such as decoding, rendering, and drawing on the zoomed image, wherein all pixel contents in the zoomed image have been rendered, and which part of the image to display depends on the pixel content of the corresponding part It is enough to draw. When the part of the image to be displayed changes, the content of the changed part of the pixels is drawn accordingly.

The images in the above embodiments can be static images, dynamic images, or videos composed of several frames of continuous images.

In addition, in other embodiments, it is also possible to adapt the original image to the screen display area in the horizontal direction to obtain a zoomed image that can be fully displayed in the horizontal direction, and then display the zoomed image in the vertical direction by sliding. the rest. For example, assuming that the size of the original image is 720*5600, since the original image is larger in the vertical direction, if the adaptation is performed in the vertical direction, the image will be small and there will be a blank space in the horizontal direction In this case, the original image can be adapted horizontally to the screen display area to obtain a zoomed image that can be fully displayed in the horizontal direction, and then the rest of the zoomed image can be displayed in the vertical direction by sliding. During specific implementation, the direction in which to perform the adaptation may be determined in combination with the size ratio of the original image and the size ratio of the screen display area.
