[0046] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0047] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0048] As described in the background technology section, the photo synthesis method of related smart TVs is still difficult to meet the needs of users in actual applications.

[0049] In the process of implementing this application, the applicant discovered that the main problem with the photo synthesis method of the related smart TV is that the image processing method of the related smart TV often requires the captured pictures, or screenshots of the TV screen, to be imported into the corresponding image editing application for editing. Otherwise, the captured pictures and the captured screen pictures can only be edited independently, and the captured screen pictures cannot be quickly and directly edited based on the screenshots at any time.

[0050] It can be seen that the screenshot and picture editing of related smart TVs are independent operating procedures. In addition, the screenshot function and picture editing are also independent of the shooting function of the smart TV, making it difficult for users to directly combine the taken photos with the screenshots for editing.

[0051] Furthermore, the applicant also found in the research that in the image processing method of related smart TVs, due to the characteristics of TV programs, it is often not convenient to pause during playback. Therefore, after taking a screenshot of the TV screen, the user needs to exit the screenshot function and then shoot again, and after the shooting is completed, enter another independent editing program.

[0052] It can be seen that the relevant image editing method is to import the image to be edited into the image editing application and then edit it. This method is obviously not suitable for smart TVs, and an operation method that can quickly and conveniently edit the captured images is required.

[0053] In view of this, one or more embodiments of the present application provide a method for synthesizing photos of a smart TV, which is based on the combination of the screenshot function and the shooting function of the smart TV.

[0054] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0055] In the embodiment of the present application, the smart TV specifically includes a TV screen, a camera, and a program for calling corresponding hardware devices and running various functional applications.

[0056] Furthermore, the smart TV has a camera function based on the configured camera, and can use the camera to take photos, obtain and store photos; it also has a screenshot function, that is, it can capture the current picture on the TV screen of the smart TV, obtain and store the captured picture.

[0057] refer to Figure 1 A method for synthesizing photos of a smart TV according to an embodiment of the present application comprises the following steps:

[0058] Step S101: Capture the TV screen to obtain a first image, and display the first image on the TV screen.

[0059] In an embodiment of the present application, firstly, a screenshot of a TV picture on a TV screen is taken using the above-mentioned smart TV with a screenshot function.

[0060] Specifically, the smart TV will capture the TV picture on the current TV screen by starting a related screen capture program.

[0061] Furthermore, after the capture operation is completed, the smart TV will automatically determine whether the captured image is effectively generated.

[0062] Furthermore, when the captured image is not successfully generated, the operation is terminated directly.

[0063] Further, when it is detected that the captured picture is successfully generated, the sub-step of “previewing the captured picture” is executed.

[0064] Specifically, when it is determined that the picture is successfully captured, a preview window is generated on the TV screen of the smart TV, and the successfully captured picture is displayed in the preview window.

[0065] In this embodiment, the captured picture displayed in the current preview window is used as the first image.

[0066] Furthermore, the first image may be placed into the first memory object through a preset first path.

[0067] by Figure 2A As a specific example, it can be seen that Figure 2A The figure shows a picture displayed on the TV screen of a smart TV. After successfully obtaining the screenshot, a preview window will be generated on the TV screen, and the captured first image will be displayed in the preview window. Figure 2A Image A in .

[0068] Step S102: in response to executing a preset start instruction, setting a background coordinate system for the first image and generating a camera area covering the first image.

[0069] In an embodiment of the present application, based on the first image obtained in the above step S101, the camera area can be displayed in the generated preview window to serve as the basis for the shooting operation in the following steps.

[0070] Specifically, based on the generated preview window, a first button that triggers the start instruction is also generated in the preview window.

[0071] Furthermore, by clicking the first button, a preset start instruction can be directly triggered, and the start instruction is specifically used to generate a camera area.

[0072] Specifically, after the start instruction is triggered, a background coordinate system may be set for the first image obtained above.

[0073] The background coordinate system may be set as a two-dimensional coordinate system and used to calibrate the specific coordinates of each point in the first image, and the origin of the coordinate system may be customized according to different specific circumstances.

[0074] Furthermore, the shape of the camera area to be generated needs to be specified first; in the preview window, a variety of different outlines will be displayed for the user to choose, each of which can be used to specify the shape of the camera area.

[0075] In a specific example, Figure 2B As shown, in the generated preview window, a photo button is also generated. By clicking the photo button, the above-mentioned start instruction can be triggered, and multiple preset outlines can be displayed, such as a narrow ellipse, a wide ellipse, a rectangle, and a diamond, etc.

[0076] Furthermore, after the user specifies the shape of the outline for the imaging area, the imaging area having the specified outline may be generated on the first image.

[0077] Specifically, the imaging area may be placed in the background coordinate system of the first image.

[0078] Among them, the image displayed in the camera area is obtained by directly calling the camera for shooting. Therefore, the coordinate system of the camera area is the camera coordinate system of the camera itself, that is, the coordinates of each point in the camera area are the coordinates in the camera coordinate system.

[0079] Based on this, it can be seen that when the imaging area is placed in the background coordinate system of the first image, each point in the imaging area that belongs to the camera coordinate system needs to be adapted to the background coordinate system.

[0080] Specifically, multiple calibration points can be set on the contour of the camera area, wherein the positions of the calibration points can be selected according to the selected contour and actual conditions. In some other embodiments, multiple positions of setting calibration points can be pre-fixed for different contours; the number of calibration points can also be set according to specific conditions.

[0081] Furthermore, the coordinates of each calibration point in the camera coordinate system are determined.

[0082] It can be seen that even if the camera coordinate system is a three-dimensional coordinate system, since the first image obtained by screenshot is a two-dimensional image, and the background coordinate system is also a two-dimensional coordinate system, when the camera coordinate system is a three-dimensional coordinate system, the dimension that vertically passes through the camera area can be removed to obtain a two-dimensional camera coordinate system; or, in some other embodiments, the camera coordinate system can be directly set to a two-dimensional coordinate system.

[0083] Furthermore, the coordinates of each calibration point in the two-dimensional camera coordinate system may be determined and used as the two-dimensional camera coordinates of each calibration point.

[0084] Furthermore, the origin of the two-dimensional camera coordinate system is determined, and the coordinates of the origin in the background coordinate system are determined and used as the two-dimensional background coordinates of the origin.

[0085] Furthermore, according to the two-dimensional background coordinates of the origin, the difference between the origin of the camera coordinate system and the origin of the background coordinate system in the background coordinate system can be determined and used as the origin difference.

[0086] Further, based on the determined first difference and the difference between each calibration point and the origin of the camera coordinate system, the coordinates of each calibration point in the background coordinate system can be determined and used as the two-dimensional background coordinates of each calibration point.

[0087] Furthermore, based on the determined two-dimensional background coordinates of each calibration point, a camera area with a specified outline may be generated in the background coordinate system, and the camera area may be overlaid on the first image.

[0088] In a specific example, Figure 2B As shown, based on the image A generated in the preview window, a wide ellipse is selected as the outline of the photographing area from among the displayed multiple outlines.

[0089] Furthermore, a camera area with a wide elliptical outline may be generated in image A, and the camera area is overlaid on image A.

[0090] Furthermore, after the imaging area covering the first image is generated, the imaging area may be adjusted, that is, the position and size ratio of the imaging area may be adjusted.

[0091] Specifically, the position of the camera area in the first image can be changed by moving the camera area in a dragging manner.

[0092] It can be seen that when the camera area is moved, its origin difference changes.

[0093] Furthermore, for each calibration point, the new two-dimensional background coordinates of each calibration point can be determined according to the difference between its two-dimensional camera coordinates and the changed origin, that is, the two-dimensional background coordinates of each calibration point after moving in the background coordinate system.

[0094] Furthermore, based on the determined two-dimensional background coordinates after the movement, the position of the entire imaging area after the movement can be determined.

[0095] In some embodiments, the size ratio of the camera area can also be adjusted by stretching.

[0096] The size ratio of the camera area may specifically include: the size of the camera area, and the size of a shooting range that can be displayed by the camera in the camera area.

[0097] Specifically, when the outline of the imaging area is stretched, the area of ​​the imaging area may be reduced according to a preset proportional method.

[0098] It can be seen that according to the change ratio between the origin of the camera coordinate system and the origin of the background coordinate system in the horizontal and vertical coordinates, the change ratio of each calibration point on the contour in the background coordinate system can be determined, thereby determining the change of the contour of the camera area in the background coordinate system, and then determining the size of the area of ​​the camera area after the change.

[0099] Furthermore, when the interior of the camera area is stretched, the size of the camera area, that is, the size of the outline, can remain unchanged, and at the same time, the shooting range of the camera displayed in the camera area can be enlarged or reduced according to a preset proportion.

[0100] Specifically, when the interior of the camera area is stretched, since the outline of the camera area is not stretched, the two-dimensional background coordinates of each calibration point in the background coordinate system can be kept unchanged, that is, the outline of the current camera area is not expanded or reduced.

[0101] Furthermore, the shooting range presented by the camera area can be directly expanded or reduced to adjust the shooting angle.

[0102] It can be seen that by determining the relationship between the origin of the camera coordinate system and the origin of the background coordinate system, and determining the relationship between each calibration point in the camera coordinate system and the background coordinate system, the camera area can be covered on the first image and the camera area can be moved and scaled.

[0103] Step S103: calling the camera to shoot, and displaying a second image obtained by shooting in the camera area.

[0104] In an embodiment of the present application, based on the camera area generated as described above, shooting can be performed by calling the camera of the smart TV.

[0105] Specifically, the camera of the smart TV can be called to shoot through the hardware abstraction layer interface, and the shot photo is used as the second image and is put into the second memory object through a preset second path.

[0106] Furthermore, by calling the second memory object in the preview window, the captured photo can be displayed in the outline of the camera area.

[0107] Step S104: synthesize the first image and the second image overlaid on the first image into a third image.

[0108] In an embodiment of the present application, based on the first image and the second image obtained as described above, a screen displayed based on the current positional relationship may be synthesized to obtain a third image synthesized by combining the photo and the screenshot.

[0109] In a specific example, Figure 2C As shown, the image B in the preview window is an image obtained by combining the image A with the photo taken in the camera area.

[0110] Furthermore, the obtained image can be saved through a preset third path.

[0111] The first path, the second path and the third path may point to the same storage location or different storage locations, and the memory objects may be the same memory object or different memory objects.

[0112] In some other embodiments, editable text may be further added to the generated third image.

[0113] Specifically, a text editing area may be generated in the third image by starting a preset editing instruction.

[0114] Furthermore, the user can edit the text editing area through the remote control of the smart TV.

[0115] In this text editing area, text characters and punctuation characters can be generated through editing.

[0116] Specifically, a second button may be set in the preview window, and the thread of the editing area may be started by clicking the second button.

[0117] In a specific example, Figure 2D As shown, in the preview window, based on image B, by clicking the edit button, the text editing area can be started. By editing in the text editing area, three letter characters including W, O, W and ! and one punctuation character are added to obtain the edited image C.

[0118] In some other embodiments, the generated third image, or the third image after text editing, can be forwarded by calling other social applications currently available on the smart TV.

[0119] Specifically, a third button may be set in the preview window, and the thread of opening other social applications may be started by clicking the third button.

[0120] Furthermore, the third image may be forwarded or published through other social applications.

[0121] In some specific examples, such as Figure 2DAs shown, in the preview window, by clicking the publish button, a thread of opening other social applications can be started to jump to other social applications, and the image C can be forwarded or published on other social applications.

[0122] It can be seen that the photo synthesis method of the smart TV in the embodiment of the present application is based on the first image obtained by taking a screenshot of the TV screen and the second image obtained by shooting, and comprehensively considers the respective coordinate systems of the first image and the camera area, so as to cover the camera area on the first image, so that the photos taken by the smart TV can be directly synthesized on the basis of the screenshot of the smart TV screen to obtain a third image synthesized by the first image and the second image, thereby realizing fast and convenient editing of the screenshot first image and improving the user experience in terms of immediacy.

[0123] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.
