Description

Technical Field [0001] The present invention relates to a device and a method for producing a repeating animation,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an animation production apparatus and a method thereof, and more particularly, to an apparatus and a method for producing a repeat animation.

Generally, an animation image means an image in which a series of still images, which are stored in advance, are continuously reproduced in a time sequence and the reproduction is repeated from the beginning when the reproduction is completed. Such animated images have an agif format capable of displaying images moving at a low capacity. The agif format has advantages of compatibility between devices and platforms because it supports uploading and sharing in services such as SNS.

When the moving picture is edited to produce an animation image, the device arranges the captured moving picture in a time order of a frame unit, designates an arbitrary frame as a start frame, and designates an end frame when a predetermined number of frames elapse . This frame range designation is possible by the user, and the user can reproduce the moving image of the designated frame range to confirm that the desired image is included. The final confirmed video of the determined frame range is generated as an animation image of the final result.

When editing a moving image for animation production, the device arbitrarily sets a start frame and an end frame for animation production.

However, conventionally, it is troublesome to determine a final range by repeating a process of reproducing a moving image in a frame range to check whether a desired portion is properly selected by a user, correcting a frame range if necessary, .

In such a case, it is difficult for the user to accurately select a desired frame from among a large number of frames on a narrow screen of the terminal, and it is inconvenient to convert most of the time required for converting the captured moving image into animation and sharing the same in the SNS .

In addition, the conventional animation image has a feature of being repeatedly reproduced. When the image difference between the first frame and the last frame is large, there is a problem that the connection between the frames is unnatural at the time of repeated reproduction. Accordingly, in order to make a natural connection between the frames, the user needs much effort to determine whether the images of the first frame and the last frame are similar.

In addition, conventionally, considering the performance of a terminal or a computer that converts a captured moving image into an animation, the number of frames of the animation is limited to a preset threshold value or less. Therefore, if the desired moving image length is equal to or greater than a threshold value, There is a problem.

Accordingly, the present invention provides an apparatus and method for editing a repeating animation.

According to another aspect of the present invention, there is provided an apparatus for producing an animation capable of being repeatedly reproduced, comprising: a camera unit for capturing an image; a display unit for outputting an animation production screen for producing an animation using the captured image; Detecting at least one frame period for producing the animation from the photographed image, displaying the detected one or more frame periods on the animation production screen, and displaying at least one frame period of the displayed one or more frame periods And a controller for generating an animation image using the image corresponding to the selected at least one frame period.

According to another aspect of the present invention, there is provided a method of producing an animation capable of repeated reproduction, comprising the steps of: outputting an animation production screen for producing an animation using the captured image when the image is captured; The method comprising the steps of: detecting at least one frame period for producing at least one frame period, displaying the detected one or more frame periods on the animation production screen, selecting at least one frame period among the displayed one or more frame periods, And generating an animation image using the image corresponding to the selected at least one frame period.

The present invention has an advantage in that a user can more easily set a frame period used for animation production, improve the quality of the produced animation, and can take the time required for animation production.

1 shows a block diagram of an apparatus for animation editing according to an embodiment of the present invention.

The animation editing apparatus of the present invention includes a control unit 100, a camera unit 110, an input unit 120, and a display unit 130.

The control unit 100 controls the overall operation of the animation editing apparatus. In particular, the control unit 100 forms an animation creation screen for creating an animation using the image captured through the camera unit 110 or a previously stored image, And outputs it through the display unit 130. Here, the animation production screen includes a frame area for providing a frame sequence extracted from the photographed image, a marker for designating a start frame and an end frame of the frame section to select a desired frame section on the frame sequence, And a preview screen area for reproducing and providing a preview image. Also, in the present invention, for example, an image in which a subject enters the angle of view outside the angle of view of the image and disappears outside the angle of view, and an object in the image move or change their shape or position at a specific position, Include the return video.

In other words, when an image for animation production is selected, the control unit 100 forms an animation production screen for the selected image and outputs it through the display unit 100. [

The control unit 100 determines the presence or absence of motion for each frame of the captured image for animation production, and determines a frame period in which the motion is present based on the motion period and the motion periodically appears. Thereafter, the control unit 100 detects a frame period according to the determination result, and outputs the frame period so that the detected frame period is displayed separately. For example, the control unit 100 may display a frame section to be distinguished using a marker.

This will be described in detail with reference to FIG. 2 and FIG.

FIG. 2 is a diagram for explaining a process of detecting one or more frame intervals for animation production according to an embodiment of the present invention.

Referring to FIG. 2, the controller 100 may detect a start frame and an end frame by determining whether there is a motion in a frame sequence of an image to detect a frame period for animation production.

The controller 100 detects frames having a motion value equal to or greater than a threshold value in the entire frame sequence as a first detection interval 200 and outputs frames having a motion value equal to or greater than a threshold value as a second detection interval 210, n < / RTI > At this time, the control unit 100 determines a motion frame and a motionless frame by using a technique for determining the presence or absence of motion such as an optical flow, and detects motion frames as a frame interval for animation production do. For example, in the case of an image in which a specific object moves, the control unit 100 sets a first frame and a second frame on the frame sequence, a second frame and a third frame, It is possible to detect the moving object by comparing and calculate the motion vector magnitude according to the moving direction of the detected object to determine whether the motion is larger or smaller than the threshold value. Also, the detected frame period can be one or more within the entire frame sequence, and is configured to be within the preset number of frames.

The control unit 100 can display a sequence frame image by designating a marker in the start frame and the end frame of each detected frame period. In addition, the controller 100 may output a video corresponding to one or more detected frame periods to a preview screen area. Accordingly, the user can check the image of the detected frame period to check whether the desired image is selected or which image is selected.

FIG. 3 is an exemplary diagram for explaining a process of detecting one or more frame periods for animation production by determining a frame period in which a motion exists and a period in which the motion periodically appears, according to an embodiment of the present invention to be.

Referring to FIG. 3, when a moving object in a selected moving image has a period, the control unit 100 can detect a start frame and an end frame by determining a motion period of the object.

The controller 100 analyzes the similarity between the reference frame and the remaining frames to determine a frame having a maximum similarity of more than a threshold value to a specific frame and specifies a specific frame as a start frame and has a maximum similarity to a specific frame It is possible to designate the determined frame as the end frame and detect it. For example, in the case of an image including a person, the control unit 100 can determine the degree of similarity using the size and position of the face.

Specifically, the controller 100 uses a similarity determination method such as sum of absolute difference (SAD) to determine a frame interval having the highest similarity to a specific frame as a first detection interval 300, The frame interval with the highest degree of similarity can be detected by the second detection interval 310 and the nth detection interval 320. [ At this time, the frame serving as the reference of the comparison object can be selected by the user.

Thereafter, the control unit 100 may generate an animation image using the detected images of one or more frame periods.

Specifically, if the length of the detected frame interval is short, the controller 100 increases the length of the animation image by combining a plurality of frame intervals, or if a detected frame interval is long, So that the length of the animation image can be reduced. At this time, the control unit 100 may provide similarity results for the first frame of the last frame of the previous frame period and the first frame of the next frame period by using the method of detecting the similarity and detecting the frame period. In the present invention, since a plurality of frame intervals similar to the start frame and the end frame are detected, the user can perform different edits such as changing the order of frame intervals or designating the number of repetitions.

The process of increasing the length of the animation image will be described with reference to FIG.

FIG. 4 is a diagram for explaining a process of increasing the length of an animation image by combining one or more frame intervals detected from an original image according to an embodiment of the present invention.

4 (a), when the frame periods A, B and C are detected in the original image, the controller 100 combines the detected frame periods A, B and C to generate an animation image as shown in FIG. 4 (b) . If the length of the animation image generated by the combination of the detected frame intervals is less than the preset image length, the controller 100 combines the frame intervals A, B, and C to fit the preset image length, And the like can be generated.

A process of reducing the length of the animation image will be described with reference to FIG.

5 is a diagram illustrating a process of reducing a length of an animation image by deleting a frame interval other than one or more frame intervals detected in an original image according to an exemplary embodiment of the present invention.

If the detected image length of one or more frame intervals is greater than a preset image length for producing an animation image, the controller 100 calculates a motion size for the detected one or more frame intervals, and if the calculated motion size is preset And detects a frame period larger than the threshold value. The control unit 100 deletes a frame period in which the calculated motion size is less than or equal to a preset threshold value, determines a similarity with respect to the detected frame period, and deletes a frame period in which the determined similarity degree is greater than a preset threshold value, The length can be reduced.

For example, the control unit 100 detects a frame period in which a motion size for each of the frame periods A, B, C, and D detected in the original image as shown in FIG. 5A is greater than a threshold value, After the interval is deleted, the similarity degree of the detected frame interval is determined, and the frame interval in which the determined similarity degree is larger than the predetermined threshold value is deleted. An animation image as shown in FIG. 5 (b) can be generated by combining the detected frame sections A, B, C, and D by this process. The animated image thus generated can be the most motion-intensive image within a predetermined time range.

In the embodiment of the present invention, the predetermined threshold value may have various values. As the predetermined threshold value for determining the motion size increases, the length of the detected frame period decreases and as the preset threshold value decreases, The length of the frame period may be increased.

The camera unit 110 receives an optical signal and outputs an image.

The input unit 120 may include a key input unit including a plurality of keys for key input, a pointing input unit for a pointing input such as a mouse, a touch input unit for touch input, To the control unit (100).

The display unit 130 may be formed of a liquid crystal display (LCD), and displays various types of function menus, various types of information provided by the user or information input by the user. The display unit 130 ) May be composed of various devices in addition to the LCD. In particular, the display unit 130 of the present invention outputs an animation production screen.
