FIG. 1 is a schematic diagram of an electronic device according to an embodiment of the invention. Referring to FIG. 1 , the electronic device 10 can be a smart phone, a personal digital assistant (PDA), a tablet PC, a notebook, a desktop computer, or a smart TV. Various electronic devices having arithmetic and display functions, such as (smart TV), are not limited thereto. In the embodiment, the electronic device 10 includes a screen 11, an input device 12, and a processor 13.

The screen 11 is, for example, various displays having a display function. The input device 12 is, for example, an input device for a user to input an operation command, such as a mouse, a keyboard, a remote controller, or a touch pad. In addition, in an embodiment, the screen 11 and the input device 12 can also be combined into a touch screen. For example, the touch screen can be a resistive touch screen, a capacitive touch screen, an optical touch screen, an acoustic wave touch screen or an electromagnetic type. A touch screen or the like can be used to detect an input tool (for example, a user's finger or a stylus, etc.). Thereby, the user can use the input tool to approach or touch the touch screen to issue an operation command to the electronic device 10 through the user operation interface displayed on the touch screen.

The processor 13 may be a micro-processor, an embedded controller, or a central processing unit (CPU), etc., and is not limited thereto. In addition, the electronic device 10 may further include a storage module (eg, a memory or a hard disk, etc.), a power module (eg, a battery), and an audio output module (eg, a speaker), etc., which are not described herein.

2 is a flow chart of a dynamic image generating method according to an embodiment of the invention. The dynamic image generating method and the electronic device 10 of the embodiment of the present invention will be described in detail below with reference to FIG. 2, and the touch screen is used as an example of the screen 11 and the input device 12. Referring to FIG. 2, in step S202, the processor 13 selects one or more regions (hereinafter collectively referred to as target regions) on an original image in accordance with an operation (hereinafter collectively referred to as a first operation). In the present embodiment, the original image is, for example, a static image.

For example, the touch screen can display the still picture, and the user can perform a click, slide or drag on the touch screen through an input tool (for example, a finger or a stylus pen, etc.). (drag) and other first operations. Then, the processor 13 can obtain one or more input trajectories corresponding to the first operation on the original image, that is, the input trajectory of the first operation such as clicking, sliding or dragging. In the present embodiment, the input track is obtained by the processor 13 when the input tool is completely in contact with the touch screen, for example. Alternatively, in an embodiment, when the input tool is close to the touch screen to a predetermined distance (for example, 0.5 to 1 cm), the processor 13 can obtain the input trajectory of the first operation, and the input tool does not need to touch. I touched this touch screen.

The processor 13 may then obtain the one or more target regions based on one or more enclosed regions formed on the original image by the one or more input trajectories. For example, when the processor 13 detects an input track and the input track can form a closed area or an almost closed area on the original image, the processor 13 can use the closed area or the almost closed area as the target area. . After obtaining the target area, the processor 13 may obtain one or more images (hereinafter collectively referred to as target images) within the one or more target areas.

For example, FIG. 3 is a schematic diagram of selecting a target area according to an embodiment of the invention. Referring to FIG. 3, when the user uses the input tool to circle a plurality of target areas in the original image 31 on the touch screen, the processor 13 can obtain a corresponding input track 302, an input track 304, and an input track 306. And obtaining a target image 312 (ie, a star) and a target image 314 (ie, a left front wheel of the vehicle) in a closed region formed by the input trajectory 302, the input trajectory 304, and the input trajectory 306, respectively. And the target image 316 (ie, the left rear wheel of the vehicle).

In an embodiment, the processor 13 can directly cover all the images in the target area as the target image, and can further cover the target area through image analysis techniques such as edge filtering. Edge images that are not part of the target image are filtered out. Taking the input trajectory 304 and the input trajectory 306 of FIG. 3 as an example, it is assumed that the user wants to use the left front wheel and the left rear wheel of the original image 31 as the target image, but the user is only roughly on the left front wheel of the vehicle. Circle around the left rear wheel. At this time, since the input trajectory 304 and the input trajectory 306 include not only the left front wheel and the left rear wheel of the vehicle, but also the edge images around the left front wheel and the left rear wheel of the vehicle, the processor 13 can be the left of the vehicle. The front wheel and the left rear wheel are referenced, and the edge images in the input track 304 and the input track 306 are filtered out, and the left front wheel and the left rear wheel of the vehicle in the original image are accurately used as the target image.

After obtaining the target image, in step S204, the processor 13 may determine one or more special effects acting on the obtained target image according to another operation (hereinafter collectively referred to as the second operation), and according to the action The special effect of the target image obtains a plurality of consecutive images. In this embodiment, the special effect includes at least one of a moving effect, a rotating effect, a zooming effect, and a color changing effect, or a combination thereof. For example, the moving effect is, for example, moving the target image along a specific trajectory, for example, rotating the target image clockwise or counterclockwise, for example, the target image is gradually enlarged or stepped down. And the color changing effect is, for example, a change in the color and/or brightness of the target image, and the like, and the present invention is not limited thereto. That is, in the multiple successive images produced, Each successive image carries the special effect that acts on the target image.

In this embodiment, the processor 13 can display a special effect menu on the touch screen, allowing the user to select a special effect to be used, and after determining the special effect to be used, the user can select the special one. The target image to which the effect works. Alternatively, the user may select the target image first, and then select a special effect to be added to the target image from the special effect menu, which is not limited by the present invention.

Moreover, in an embodiment, the processor 13 may also prioritize different operational gestures to different special effects. For example, when the processor 13 detects a clockwise rotation gesture or a counterclockwise rotation gesture acting on the target image 314 (ie, the left front wheel of the vehicle) and the target image 316 (ie, the left rear wheel of the vehicle) The processor 13 may add a rotation effect (eg, clockwise rotation or counterclockwise rotation) to the target image 314 and the target image 316, and accordingly generate a plurality of consecutive images with this rotation effect. When these successive images are played continuously or sequentially, the dynamic effect of clockwise rotation or counterclockwise rotation of the left front wheel and the left rear wheel of the vehicle can be presented. In addition, the moving effect, the zooming effect, and the color changing effect can also correspond to different gestures, which will not be repeated here.

For example, FIG. 4 is a schematic diagram of a moving effect according to an embodiment of the invention. Referring to FIG. 4, when the user performs a second operation on the touch screen through the input tool to add a moving effect on the target image 312 (ie, the star), the processor 13 may determine the action on the target according to the second operation. The special effect of the image 312 is a moving effect, and a continuous image 41-43 is generated accordingly.

In the continuous image 41, it is assumed that the target image 312 is present at the position 402. In the continuous image 42, the target image 312 is changed from the previous position 402 to appear at the position 404. In the continuous image 43, the target image 312 is further changed from the previous position 404 to appear at the position 406. Thereby, when the continuous images 41 to 43 are continuously or sequentially played, the dynamic effect of the stars moving from the position 402 to the position 406 can be presented. However, for the user, for example, the user only needs to drag the target image 312 from the position 402 to the position 406 when performing the second operation, or set the starting position of the target image 312 to the position 402 and the end point. The position is position 406, which greatly simplifies the complicated procedures required for the production of moving images.

For another example, FIG. 5 is a schematic diagram of a zooming effect according to an embodiment of the invention. Referring to FIG. 5, when the user performs a second operation on the touch screen through the input tool to add a zoom effect on the target image 312 (ie, the star), the processor 13 may determine the action on the target according to the second operation. The special effect of the image 312 is a scaling effect, and accordingly a continuous image 51-53 is produced.

In the continuous image 51, it is assumed that the target image 312 has a first size (i.e., original size). In the continuous image 52, the target image 512 has a second size that is greater than the first size. In the continuous image 53, the target image 514 has a third size that is larger than the second size. Thereby, when the continuous images 51 to 53 are continuously or sequentially played, a dynamic effect in which the stars are enlarged from the first size to the third size can be exhibited. Similarly, for the user, for example, the user only needs to enlarge the target image 312 from the first size to the third size through a zoom-in gesture when performing the second operation, or set the target image 312. Magnification, etc., but also It simplifies the complicated procedures required to create dynamic images in the past.

Then, in step S206, the processor 13 may generate a dynamic image based on the continuous image, for example, synthesize a plurality of consecutive images into one dynamic image. In addition, the user can also customize the format of the output dynamic image according to the needs. In this embodiment, the format of the dynamic image includes a Graphics Interchange Format (GIF) and a Portable Network Graphics (PNG), and is not limited thereto.

In this embodiment, after obtaining a plurality of consecutive images, the processor 13 may also sequentially display the consecutive images on the touch screen to preview the dynamic image to be obtained. Then, when the user performs a confirmation operation through the input tool, for example, clicking a confirmation button on the touch screen, the processor 13 can receive the confirmation operation, and generate a dynamic image based on the continuous images according to the confirmation operation. . On the other hand, after previewing the moving image to be obtained, if the user finds that the dynamic image is different from the expected or does not achieve the desired effect, the user can perform a continuous editing operation through the input tool, for example, on the touch screen. Clicking the Continue Edit button causes the processor 13 to repeatedly perform the above steps S202 and S204.

In addition, in an embodiment, after the dynamic image is generated, if the user still wants to add the remaining special effects to the dynamic image, the dynamic image may continue to be the original image in step S202, and Step S202 to step S206 are repeatedly executed by the processor 13 to generate another moving image. Alternatively, in an embodiment, the original image may also be a dynamic image that has a special effect at first, and the invention is not limited thereto.

It is worth mentioning that although the above embodiment is exemplified by a control screen including the screen 11 and the input device 12, those of ordinary skill in the art will appreciate that the present invention is equally applicable to the electronic implementation of the screen 11 and the input device 12, respectively. Device. In addition, the above method steps may be implemented by different software or firmware modules, respectively. For example, in the present embodiment, the software or firmware modules may be stored in the memory or hard disk of the electronic device 10, and may be loaded into the processor 13 to perform the above method steps. In addition, in an embodiment, the foregoing method steps may also be performed by different hardware circuits, and the invention is not limited thereto.

In summary, the dynamic image generating method and the electronic device in the embodiment of the present invention allow a user to select a target image to be added to a special effect and a special effect by using a circle selection operation on a static/moving image. Kind, thereby producing a plurality of consecutive images with this special effect, and generating a dynamic image based on these continuous images. Therefore, after the user adds the favorite effect to the static/moving image, the electronic device can automatically generate a corresponding dynamic image, simplifying the cumbersome procedures required for the previous production of the dynamic image, and effectively improving the user experience. .

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art can make some changes and refinements without departing from the spirit and scope of the present invention.
