Image display method and image display system applying the same {Image display method and Image display system applying the method}

The present invention relates to an image display method representing a moving object using a plurality of still images and an image display system to which the method is applied.

Recently, with the development of broadcasting and communication technology, various services have been provided to terminals such as TVs, PDAs, and cellular phones. In particular, such terminals may be provided with various image information by providing a display device. However, there is a problem in that the video information does not move or switch smoothly during playback even if the data capacity is large and transmitted to the terminal.

Accordingly, an aspect of the present invention is to provide an image display method capable of smoothly displaying movement or switching of a screen, and an image display system using the same.

The present invention provides an image display method for displaying an original still image, determining a frame representing a part of the original still image from the original still image by a predetermined operation, and displaying the frame.

In the present invention, the frame refers to a part of the original still image. For example, when the original still image is a map image, the frame may be an enlarged image of a part of the local area. Alternatively, when a plurality of cuts are included in one still original image, such as a cartoon image, an image corresponding to each cut may be referred to as a frame.

In the image display method, the frame may be determined using a size such as a width, a height, and the like of the frame. The frame that enlarges / reduces the original still image may be determined using the size of the frame. Further, after displaying the original still image by using a depth value for zooming in / out, the displaying of the frame, that is, the process of enlarging or reducing the original still image may be continuously displayed. Such a method displays a whole map image composed by combining at least one frame representing local areas, and selects and enlarges the desired local area by using a depth value for zooming in and out, thereby allowing the user to check the entire map image. The overall route and the detailed route of the local area.

The depth value for the zoom can be set arbitrarily or automatically.

In the image display method, the frame may be determined using the initial position of the frame or the final position of the frame from the original still image.

In the image display method, when the original still image represents the movement of the object composed of at least two frames, the frame determining step includes a first frame representing a first operation of the object and a second of the object. The second frame indicating the operation may be determined through a predetermined operation. Furthermore, the first operation of the first frame and the second operation of the second frame may be continuously displayed using a depth value for the movement between the first operation and the second operation of the object. Therefore, when the movement of the object is composed of a plurality of cuts and displayed like a cartoon image, the movement of the object can be displayed more vividly.

The present invention also provides an image display system including an image input unit for inputting an original still image, a frame determination unit for determining a frame from the original still image through a predetermined operation, and a display unit for displaying the frame determined from the frame determination unit. To provide.

In the image display system, the frame determiner may determine a frame through the operation using the size of the frame from the original still image.

The image display system further includes a depth value determiner for enlargement / reduction that determines a depth value for enlargement / reduction of the image, and the display unit displays a still image image using the depth value for enlargement / reduction. The frame can be displayed by continuously zooming in or out.

In the image display system, when the original still image represents the movement of the object composed of at least two frames, the frame determination unit may include a first frame representing a first operation of the object and a second operation of the object. The second frame indicating may be determined.

In the image display system, the frame determiner may determine a frame through the operation using an initial position of a frame or a final position of a frame from the original still image.

The image display system may further include a motion depth value determiner configured to determine a depth value for a motion between the first and second motions of the object, wherein the display unit uses the motion depth value to determine the depth value. The first frame and the second frame may be displayed to continuously represent the second operation.

The present invention can eliminate the inconvenience of scrolling by finding and displaying a frame determined through a predetermined operation at once without scrolling the original still image to display a desired frame.

In addition, the present invention is to determine a frame from a two-dimensional original still image through a predetermined operation and to move to the screen for displaying the frame in the original still image using the depth value for the enlargement / reduction in displaying the frame The process or the process of the transition can be displayed smoothly.

In addition, the present invention is to determine and display the first frame showing the first motion of the object and the second frame showing the second motion of the object from the original still image showing the movement of the object, respectively, The depth value for the movement may be used to smoothly display a process of moving or switching from the original still image to the frame and moving or switching from the first frame to the second frame.

Hereinafter, with reference to the accompanying drawings the present invention will be described in more detail.

1 is a block diagram showing an image display system according to the present invention.

Referring to FIG. 1, the image display system includes an image input unit 10, a user input unit 20, a frame determiner 30, a display unit 60, and a signal processor 70.

The image input unit 10 may be a memory that stores an original still image, or may be a communication interface that receives an original still image from an external server in a wired or wireless manner, or may be an interface that receives an original still image from a broadcasting station. have.

The user input unit 20 generates a signal to control the operation of the image display system by the user, and may be formed of a function key, a touch screen, or the like mounted on the image display system, or may be separated from the image display system, such as a keyboard and a remote controller. It may be formed in the form of a controller.

The frame determiner 30 determines a frame from the original still image according to a predetermined operation. Specifically, if the frame is an image representing a local area of the original still image, the frame may be determined according to a predetermined operation using a size such as a height and a width of the frame from the original still image. Or when the original still image is composed of a plurality of frames, for example, when the original still image is composed of a plurality of cuts according to the motion of the object to express the movement of the object, a first frame representing the first motion of the object and the first object of the object. A second frame indicating the two operations may be determined. In this case, each frame may be determined according to a predetermined operation using the initial position and the final position of the frame.

The operation may be arbitrarily set by a user or a manufacturer. When a plurality of frames are determined according to the operation, each of the frames may be displayed in order, but only necessary frames may be selected and displayed. For example, the first frame, the second frame, and the third frame can be calculated from the still image through a predetermined operation. However, the second frame is determined to be difficult to implement the display. It may be displayed as a frame and a second frame. Accordingly, when only the first frame and the second frame to be displayed are viewed, even if they are not generated according to the operation, the second frame that is not displayed is considered. That is, the above case also falls within the scope of the present invention.

As shown in FIG. 2, the frame determiner 30 according to the present exemplary embodiment includes a frame initial position determiner 31, a frame final position determiner 32, a frame size determiner 33, and a frame configuration unit 34. ) May be included. The frame determiner 30 may include only the frame initial position determiner 31, the frame final position determiner 32, and the frame configurer 34, or the frame size determiner 33 and the frame configurer. It may also be made of (34).

In the present invention, the frame is a part of the original still image displayed on the display unit 60. For example, in the case of a cartoon image, the cartoon cut may correspond to the frame. Alternatively, in the case of a map image, an image corresponding to a local area of the entire map image may be determined as one frame. In order to determine such a frame, an initial position, a final position, a frame size such as a width and / or a height are required. Therefore, in the present embodiment, the initial position of the frame is determined by the frame initial positioning unit 31, the final position of the frame is determined by the frame final positioning unit 32, and the frame size determining unit 33 is used. By determining the width and height of the frame, the frame configuration unit 34 may determine one frame using the determined values.

The initial position, final position, size, etc. of the frame may be determined by input of the producer, provider, or observer that generated the original still image, or may be set to be determined automatically.

For example, the frame may be determined by an operation such as Equation 2 and 3 or Equations 4 and 5 according to Equation 1 below, and the variable values of the determined frame are shown in Table 1 below. X and Y represent horizontal and vertical positions on the two-dimensional coordinate plane, respectively, W denotes the width of the frame, and H denotes the height of the frame.

[Equation 1]

Applicable object = Previous object + (final object-previous object) * depth

[Equation 2]

X0 = X0 + (X1-X0) * 0.5

[Equation 3]

Y0 = Y0 + (Y1-Y0) * 0.5

[Equation 4]

W0 = W0 + (W1-W0) * 1

[Equation 5]

H0 = H0 + (H1-H0) * 1

For example, since the initial position of the first frame 1f is (0,0), the final position is (100,100), and the depth value for movement is 0.5, the initial position of the second frame 2f is (50,50) Can be determined. In this manner, the third frame 3f, the fourth frame 4f, and the like may be determined. Since the size of the frame has a depth value of 1 for enlargement / reduction, all the frames 1f, 2f, and 3f..Lf may have a width of 10000 and a height of 10000.

Referring to the display unit 60 again with reference to FIG. 1, the frame determined by the frame determiner 30 may be displayed on the display unit 60. The display unit 60 may be an organic light emitting display (OLED), a liquid crystal display (LCD), an electrophoretic display (EDD), or the like.

The signal processor 70 may process an overall signal to control each component for the operation of the image display system as described above.

In addition, the image display system 100 may further include a movement depth value determiner 40. The movement depth value determiner 40 determines a depth value for movement between the first motion and the second motion of the object. When the first frame represents the first operation of the object and the second frame represents the second operation of the object, the object is moved from the first operation to the second frame in the process of moving or switching from the first frame to the second frame. The depth value is determined to display successive smooth movements in motion.

In addition, the image display system 100 may further include a depth value determiner 50 for enlargement / reduction. The depth value for zooming in or out also displays an enlarged process of displaying a frame representing a portion of the original still image after displaying the original still image, or vice versa, so that the screen is continuously smoothed or switched continuously. The depth value can be determined for representation.

Each of the components described above may be included in one device, or may be included in separate devices that are externally distinguished.

3 is a flowchart illustrating an image display method according to an exemplary embodiment.

Referring to FIG. 3, first, an original still image is provided (S10). Then, the frame is determined from the original still image (S20). The frame may be determined by position information, size information, and the like of the frame. The information may be generated together with the original still image by the writer and / or provided by the service provider, or may be further input after the original still image is provided by the user. In addition to the above information, a depth value for movement and / or a depth value for enlargement and reduction may be used.

In the process of moving or switching the depth value for the movement from the first frame representing the first motion of the object to the second frame representing the second motion of the object, the first motion and the second motion are continuously It may be a control value for expressing a smooth movement. Therefore, when the movement of the object is represented by at least two frames, the motion of the object may be displayed more smoothly by controlling the depth value for the movement.

In addition, the depth value for the enlargement / reduction may be determined to display the screen smoothly or continuously by moving or switching the screen in the process of enlarging or vice versa to a frame corresponding to one local area of the original still image.

After determining the frame using the location information, the size information, and the depth values as described above, the first frame can be displayed (S30), and the second frame can be displayed continuously to the first frame (S40). Displaying the frames continuously can be done by user input, or can be done automatically using a function such as automatic flipping.

4 to 8 illustrate screens on which images are displayed according to the method illustrated in FIG. 3. In the present exemplary embodiment, a cartoon image is received from a TV station serving a cartoon on a TV, which is a home terminal, and the cartoon image is displayed. Specifically, a cartoon interactive broadcast is transmitted from a broadcasting station to each home, and a user's control signal is transmitted to a broadcasting station by using a TV remote controller, so that the cartoon image can be viewed according to the user's convenience.

Referring to FIG. 4, the original cartoon image is entirely displayed on the screen of the display unit 60 of the TV 100. The original full ring image is received from a cartoon-providing station, and currently includes six images of the entire surface. The left side shows three cut images of the pitcher throwing the ball, the right side shows two shots of the batter batting the ball, and the defender catches the ball as the last cut image. will be.

Specifically, the first frame 200 shows the motion before the pitcher throws the ball, the second frame 210 is the initial motion of the pitcher throws the ball, the third frame 220 the pitcher throws the ball This is a representation of the later behavior.

However, if the original cartoon image is displayed as a whole, the image of each cut cannot be accurately identified. In addition, when the text is included in each cut, the text may be read only when the text is close to the TV screen, thus increasing eyestrain. Alternatively, there is an inconvenience in finding the desired area by enlarging the original cartoon image and moving it little by little using the scroll bar. The present invention can solve the above problems, and if the original cartoon image can be divided into a plurality of cuts, such as a portion of the original cartoon image, a cartoon image, by determining the frame corresponding to the cut each You can select and zoom in on the frame to view the cartoon continuously. Furthermore, by setting the depth value for the movement at the time of frame determination, it is possible to dynamically express the full ring image expressing the motion by smoothly controlling the screen movement or switching between the frames.

The frames 200, 210, and 220 may be determined according to the intention of the constituent artist while generating the original cartoon image, or may be determined by the cartoon provider or the observer. The frames 200, 210, and 220 may be determined through a predetermined operation using the initial position, the final position, and the size information of the frame. In addition, it may be determined using a depth value for movement of the frame and / or a depth value for zooming in / out.

When the user transmits the first frame selection control signal to the TV 100 using the remote controller 20, the first frame 200 is selected and enlarged as shown in FIG. 5 according to the control signal. In this case, the screen may be smoothly moved or switched by the depth value for the enlargement / reduction or / and the depth value for the movement.

When the user transmits the second frame selection control signal to the TV 100 using the forward direction key of the remote controller 20, the second frame 210 is displayed as shown in FIG. 6 according to the control signal. In this case, the movement or the transition from the first frame 200 to the second frame 210 may be smoothly expressed due to the depth value for the movement. Accordingly, the pitcher movement of the first frame 200 may be continuously displayed from the pre-hitting operation of the second frame 210 to the viewing operation of the second frame 210, thereby allowing the viewer to watch a more realistic screen. In particular, in the case of action comics, a dynamic motion expression can be vividly delivered to the viewer.

7 shows only the second frame 210 on the screen of the display unit 60. In the screen illustrated in FIG. 6, the remote controller 20 may be enlarged. In this case, the depth value for the enlargement / reduction is set, and the screen movement or switching can be performed smoothly.

According to FIG. 8, a user may generate a third frame selection control signal by using the direction key button of the remote controller 20, and search and display the third frame 220 at once according to the control signal. The third frame 220 illustrated in FIG. 8 may be displayed by moving from the operation of the second frame 210 illustrated in FIG. 7 to the last operation in which the pitcher threw the ball.
