Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a method for adjusting a projected image, which is used in an electronic device according to an exemplary embodiment, in which a projection device and the electronic device may establish a communication connection using various wired or wireless technologies in the present disclosure. For example, the connection means may include, but is not limited to: bluetooth, WiFi (Wireless-Fidelity), 2G network, 3G network, 4G network, etc., and the electronic device may be, for example, a smartphone, a tablet, a Personal Digital Assistant (PDA), a multimedia player device, a computer, etc. As shown in fig. 1, the method comprises the steps of:
in step S11, size information of the first image projected onto the projection screen by the projection device is acquired.
In an embodiment of the present disclosure, the size information of the first image includes information for characterizing the size of the first image, including, for example, the length, width, and diagonal size of the first image, and so on.
In one possible embodiment, the size information of the first image may be calculated according to parameters such as a projection distance between the projection device and the projection curtain, a focal length of a lens of the projection device, and a size of a display panel in the projection device.
It should be noted that, in the embodiments of the present disclosure, the projection curtain may be a professional curtain for projection, a wall surface, or the like, which is not limited by the present disclosure.
In step S12, the second image is displayed on the display interface of the electronic device according to the size information of the first image.
The second image may be a scaled image of the original image corresponding to the first image. In the embodiment of the disclosure, the original image may be an image that needs to be projected by a projection device in an electronic device, or may also be an image that needs to be projected by a projection device in another device. For the former, the electronic device can directly call the original image, and the original image is scaled to a proper size according to the size information of the first image to obtain a second image and the second image is displayed on a display interface of the second image; for the latter, the electronic device may establish a communication connection with another device, receive the original image sent by the other device through the communication connection, and scale the received original image to an appropriate size according to the size information of the first image to obtain a second image and display the second image on a display interface of the electronic device.
Optionally, the size information of the second image corresponding to the size information of the first image may be determined according to a preset scaling, and the second image may be displayed on the display interface of the electronic device according to the size information of the second image. For example, after the size information of the second image is determined according to the preset scaling, the original image may be scaled according to the size information of the second image and displayed on the display interface, so as to obtain the second image.
It should be noted that the preset scaling ratio can be preset. Specifically, as a possible implementation manner, the maximum image size information and the size information of the display interface that can be projected by the projection apparatus on the projection curtain may be obtained, and the preset scaling may be set according to the maximum image size information and the size information of the display interface, for example, the preset scaling may be set as a ratio of the maximum image size to the size of the display interface. The maximum image size can be calculated according to parameters such as the maximum projection distance between the projection device and the projection curtain, the maximum lens focal length of the projection device, the size of a display panel in the projection device and the like.
In step S13, when an adjustment instruction for the second image is received, a control instruction for instructing the projection apparatus to adjust the size of the first image is sent to the projection apparatus according to the adjustment instruction.
The electronic device may have a second image adjustment function, which may be implemented by a corresponding APP pre-installed on the electronic device.
It should be noted that, in order to further facilitate the user to adjust the second image, the target node of the second image may also be displayed on the display interface of the electronic device, where the target node may include, but is not limited to, a corner point, a center point, a midpoint of a boundary line, and the like of the second image.
In an embodiment of the present disclosure, the user may adjust the size of the second image by inputting an adjustment instruction, for example, the user may drag a boundary line of the second image in a direction close to the center point or away from the center point, drag a corner point of the second image in a diagonal direction, and the like.
After receiving an adjusting instruction input by a user, the electronic device sends a corresponding control instruction to the projection device in response to the adjusting instruction input by the user, and the projection device correspondingly zooms the projected first image after receiving the control instruction. For example, when receiving an angular point that a user drags a second image to a central point along a diagonal direction, determining target size information of the first image by obtaining final size information of the second image, sending a control instruction carrying the target size information of the first image to the projection equipment, and adjusting corresponding node coordinates by the projection equipment in response to the control instruction to reduce and adjust the first image to a target size.
The projection image adjustment method described above will be described below with reference to specific implementation scenarios. As shown in fig. 2 and 3, the size information of each image and the size information of the projection curtain are respectively represented by respective diagonal dimensions, the electronic device 100 is a smart phone, and the original image in the electronic device 100 is projected onto the projection curtain 300 through the projection device 200 to form a first image 310 with a size of 150 inches. Accordingly, as shown in fig. 2, the electronic device 100 may display the original image on its display interface 110 (i.e., display the second image 111) in an appropriate size after zooming. Since the projection curtain 300 is only 70 inches, in order to make the projected first image 310 fit to the projection curtain 300, the user can drag four corner points (target nodes) of the second image 111 along the diagonal direction toward the center point, and the first image 310 projected on the projection curtain 300 by the projection apparatus 200 is correspondingly reduced, so that the user can reduce the first image 310 to 70 inches by dragging the target nodes of the second image 111 to a proper position, and thus fit to the projection curtain 300, as shown in fig. 3.
Through the technical scheme of the embodiment, the second image corresponding to the size information of the first image is displayed on the display interface of the electronic equipment, so that the size of the first image projected by the projection equipment can be visually displayed for a user, the user can conveniently and quickly adjust the projection image projected by the projection equipment to a proper size, and the projection image adjusting efficiency is improved.
In order to further improve the projection image adjustment efficiency, in another embodiment of the present disclosure, as shown in fig. 4, the method may further include:
in step S14, size information of the projection screen is acquired.
In embodiments of the present disclosure, the dimension information of the projection curtain includes information characterizing the dimensions of the projection curtain, including, for example, the length, width, and diagonal dimensions of the projection curtain, among others.
Alternatively, the size information of the projection curtain may be directly input by the user.
Optionally, the size information of the projection curtain may also be acquired by acquiring an image of the current projection condition through the image acquisition device. The image acquisition device may be an image acquisition device built in the electronic device, or an image acquisition device carried by the projection device.
Specifically, the image acquisition device can photograph the projection curtain and the first image projected on the projection curtain to obtain the image of the current projection condition. Then, a series of processing such as preprocessing, gray scale conversion, segmentation, feature extraction and the like can be performed on the current projection condition image, the boundary line of the first image and the boundary line of the projection curtain are extracted, the size difference between the first image and the projection curtain is obtained through analysis, and therefore the size information of the projection curtain can be obtained.
In step S15, the third image is displayed on the display interface of the electronic device according to the size information of the projection screen.
Optionally, after the size information of the projection curtain is acquired, the size information of a third image representing the projection curtain can be determined according to a preset scaling and displayed on a display interface of the electronic device. Therefore, the electronic equipment can visually display the difference between the size of the projection curtain and the size of the projection picture to a user by displaying the second image and the third image on the display interface of the electronic equipment, so that the user can adjust the projection image to the size adaptive to the projection curtain more quickly and accurately, and the projection image adjusting efficiency is further improved.
For example, as shown in fig. 5, the size information of each image and the size information of the projection curtain are respectively represented by respective diagonal dimensions, the electronic device 100 is a smartphone, the original image in the electronic device 100 is projected onto the projection curtain 300 through the projection device 200 to form a first image 310 with a size of 150 inches, and the projection curtain 300 has a size of 70 inches. Accordingly, the electronic device 100 may display the second image 111 and the third image 112 in the corresponding sizes on the display interface 110 thereof according to the size of the first image 310 and the size of the projection curtain 300, respectively. Thus, the user can refer to the third image 112 representing the projection screen, and drag the corner (target node) of the second image 111 to a proper position, so as to reduce the first image 310 to a size suitable for the projection screen 300.
