FIG. 3 illustrates that three operations are displayed as operations of a screen of a moving image separated by a predetermined time unit in an intermediate process of the present invention.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display board, and more particularly, to a field of displaying a moving image using a blinking device such as an LED.

It is often used to communicate information to others, such as advertisements, by using the billboard. Advertisements with simple text or pictures will be the least expensive, but they will be less effective to convey the user's desire to buy or convey meaning than ads using video.

At this time, if the advertisement is mounted on a display board such as LCD or PDP, it will be able to execute effectively including the video. However, the display board using such a device is too expensive and requires a large cost for maintenance. In other words, the effect of the advertisement may be good, but the effect will be small in general because it costs too much for the effect of the advertisement.

LEDs are widely used as being able to be installed on an electronic board and displaying moving images including video as well as general letters and figures. When using a LED to represent a video, LEDs should be installed for each pixel of R, G, and B in the unit of pixels or dots. However, for example, if a video having a resolution of 640x480 is implemented using an LED device, the number of LEDs is needed more than hundreds of thousands, and even if the resolution is reduced, a huge number of LEDs are required. Using such a large number of LEDs has a problem that requires too much cost in terms of price and maintenance and repair of the original product. In addition, there is a problem that the area for installing the LED for supporting the above resolution is too large.

To solve this problem, module type LEDs can be used in an array or non-array method, but in the former case, it is impossible to express delicate graphics. In the latter case, a module can be used to express delicate graphics. There is still a problem that the number of LEDs becomes too large, and as a result, the size of the display board on which the LEDs are installed is too large. This problem eventually leads to a problem of rising costs, and there is still a problem that a display board displaying an advertisement including a video cannot be smoothly used using a device such as an LED.

Technical problem to be solved by the present invention, in order to solve the above problems, while using a flashing means such as a dot-type LED, but using a means for blinking to minimize the number of flashing means used, The present invention provides an electronic display board that displays a moving image by using a device and a blinking means.

According to the present invention for solving the above technical problem, a video display method using a flashing means, the method comprising the steps of: (a) receiving a video to be expressed using the flashing of the flashing means as an input; (b) separating an object including a motion from the input video; (c) separating the trajectory of movement of the separated object by a predetermined time unit; (d) finding a portion where the movements of the moving object overlap each other in the separated unit of time; (e) determining an area in which the portions of the non-overlapping object move around the overlapping portions in units of time separated in step (c); And (f) the overlapping portion determined in step (e) for each time unit is a point where the flashing means is fixed and continuously lit, and the moving portion is turned on at the point where the flashing means is turned off according to the moving state of the object. The step of determining a point or turned off from the point that is turned on; characterized in that it comprises a.

In this case, the separating of the object including the motion in the step (b) is preferably obtained by removing the background of the state does not change from each frame of the input video.

In addition, it is preferable that the predetermined time unit of step (c) is changeable, and the means for blinking is an LED element, and the predetermined time unit of step (c) may be changed according to the reaction rate of the LED element. This is preferred.

According to another aspect of the present invention, there is provided a video display apparatus using a flashing means, comprising: a video input unit receiving a video to be expressed using flashing of the flashing means; A video separator for separating an object including a motion from a video inputted through the video input unit; An hourly separator that separates a moving path of the object separated by the video separator by a predetermined time unit; An overlap determination unit for finding a portion where the movements generated by the moving object overlap each time unit separated by the time separation unit; An operation determination unit determining an area in which the portions of the object that are not overlapping move around the portions where the operations found by the overlap determination unit overlap, in units of time separated by the time division unit; And an overlapping portion determined by the overlap determination unit for each time unit is a point at which the blinking means is fixed and keeps on lighting, and the moving portion is turned on or off at a point where the blinking means is turned off according to the moving state of the object. It characterized in that it comprises a; flashing means positioning unit to determine that the point is turned off.

In this case, the video separator may separate an object including a motion from each frame of the input video except for a background whose state is not changed.

According to the present invention for solving the above further technical problem, an electric signboard which expresses a moving picture by means of blinking means is produced according to the configuration of the method or apparatus described above, and the blinking means is performed in the predetermined time unit. It is preferable to control the flashing means to be turned on and off repeatedly.

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

Figure 1 illustrates the flow of a method of presenting a video by means of blinking means in accordance with the present invention.

Receiving a video to be expressed using the blinking means of blinking means such as an LED (step 100), separating the object containing the movement from the input video (step 110), and determining the trajectory where the separated object moves. By separating the time unit of the step (120), and finds the overlapping motions generated by moving the moving object for each time unit (step 130),

Then, the moving parts of the non-overlapping objects around the overlapping part are determined in units of time separated in step 120 (step 140), and the overlapping parts determined in step 140 for each time unit are fixed by the flashing means. In the lighting point, the moving part is determined to be turned on at the point where the flashing means is turned off according to the moving state of the object or turned off at the turned point (step 150).

2 is a block diagram showing the configuration of an apparatus for representing a moving picture by means of blinking means such as an LED according to the present invention.

This apparatus is a video input unit 200 for receiving a video to be expressed using the flashing means of the flashing means as input, video separation unit for separating the object containing the motion from the video input through the video input unit 200 (210), the video separating unit 210 is separated by the time-specific separation unit 220, the time-specific separation unit 220, the time-dependent separation unit 220 is generated by moving the moving object for each time unit separated The overlap determination unit 230 which finds the parts where the operations overlap, and the area in which the parts of the object that are not overlapped move around the parts where the motions found by the overlap determination unit 230 are moved in units of time separated by the hourly separator 220. The overlapping portion determined by the operation determination unit 240 and the overlap determination unit 230 for each time unit is determined as the flashing means is fixed and is continuously turned on. The moving part includes a flashing means positioning unit 250 which determines that the flashing means is turned on or off at the point where the flashing means is turned off according to the moving state of the object.

The following describes an example of implementing the present invention according to the method of FIG. 1 using the apparatus of FIG.

The video input unit 200 receives the video as an input (step 100). In this case, the video includes not only a video that can be viewed through a movie or a computer screen, but also drawings that can be viewed as a video through a small image or a manual work of lower quality.

Drawings that can be shown in video, for example, will be seen as a natural video when viewed at 24 planes per second, even if the number of screens per second is fine. Therefore, the present invention can be input as a moving picture that can be used in the present invention if the still drawings created by hand can also be seen as a moving picture is connected to the still drawings.

The video separator 210 separates an object including a motion from the input video in step 110. In this case, it is preferable that the object including the motion is obtained by excluding a background whose state does not change from each frame of the input video.

A video is generally composed of frames. A moving picture created with the drawings described above may also regard one still picture as one frame.

If a moving object is not included in the moving picture, this may not be a moving picture, which is a simple still picture, and the image may be processed to be expressed using the LED of the electronic display without using the present invention.

If a moving object is included in the video, each frame is read and each frame is compared with the neighboring frame by pixel. The background, which is the non-moving part of the video, does not change for each frame, and the moving object continuously changes the pixel properties for each frame. have.

Such a separation method between a background and an object of a moving image has already been introduced commercially available technology such as separating moving parts from an image according to the MPEG standard, and can be executed by various programs. Therefore, a person having ordinary knowledge in the art to which the present invention pertains to such a technique may easily perform step 110, and thus further description thereof will be omitted.

The hourly separator 220 separates the trajectory of the object separated by the video separator 210 in a predetermined time unit (step 120).

Normal movies such as movies are played at 24 frames per second. As described above, in the present invention, the video inputted in step 100 is separated at an appropriate time interval to implement the video. At this time, it can be separated into 24 frames per second like a movie. However, when configuring the LED using LED as in the purpose of the present invention, to minimize the number of LED devices used to configure too many frames per second may cause a problem of increased cost, if too few frames per second It may be overwhelming to see what the video looks like.

If the number of frames of the movie input in step 100 is greater than the number of frames separated in step 120, for example, if the input movie is 24 frames per second, and the frame separated in step 120 is 3 frames per second, One frame of the first eight frames may be selected to determine the first frame in step 120.

At this time, selecting one frame out of eight frames may analyze each frame to select a frame having the largest degree of movement of a moving object included in each frame. Alternatively, the first or last eighth frame may be arbitrarily determined.

At this time, the predetermined time unit of 120 steps may be changed. As will be described below, increasing the time unit has the effect of reducing the number of LED elements to be installed in the electronic display panel generated according to the present invention.

At this time, it is preferable that the unit of the predetermined time can also be changed according to the reaction rate, which is the interval until the time of driving the LED element to emit the actual light. In other words, if the response speed of the LED is fast, the unit can be switched quickly by reducing the unit of the predetermined time. On the contrary, if the unit is reduced, the effect of the video will be small even if the unit of the predetermined time is reduced, so that the time unit can be increased. will be.

FIG. 3 illustrates that three operations are displayed as operations of a screen of a moving image separated by a predetermined time unit in an intermediate process of the present invention.

Reference numeral 300 is a part which does not change to a background screen. The configuration of reference numerals 310 to 330 indicates that the fish appear to be in three shapes for a certain period of time for the sake of convenience of explanation of the spurting and jumping of the water surface.

The hourly separator 220 separates moving objects of 310, 320, and 330 in units of time.

The overlap determination unit 230 finds a portion where the motions generated by the moving object overlap each time unit separated by the hourly separator 220 (step 130). For example, when the fish of 310 of FIG. 3 spurs the surface of the water, the shape of the tail portion may move from side to side several times in a short time. At this time, the center part where the tail moves is not changed much, but the tail fin part will be severely moved. Or in a scene where a person runs, the torso will have little movement, but the movement of the arms and legs will have a lot of movement.

As such, the parts with little movement of the object will overlap each other when the frames of the video overlap. Therefore, the overlap determination unit 230 may find a part where the operation overlaps from the result of overlapping each frame of the video.

The operation determiner 240 determines an area in which the portions of the object that are not overlapped move, based on the overlapping operation of the overlap determination unit 230, in units of time separated by the hourly separator 220 (step 140). . As described above, the parts where the motions do not overlap can be found from the result of overlapping each frame of the video.

The part where this motion does not overlap becomes an area with large motion, and the area with large motion becomes an area which needs to be specified so that a video motion can be made using LED.

For example, when three frames are used in one second as described above, the operation determiner 240 determines a portion in which three operations do not overlap in one second. This is not to determine the frame of the original video according to the time zone, but to determine three frames based on the large movement as described above.

The flashing means positioning unit 250 is a part where the operation detected by the overlap determination unit 230 overlaps every time interval determined in step 120 or after the time interval elapses. Decide This determined point becomes a point on the display board, and the LED attached to the point corresponds to the non-moving area. In other words, if it is configured to have three frames in one second, the LED of the non-moving part is kept on. Of course, if the color is necessary to install the LED of the corresponding color to be lit.

In addition, the blinking means positioning unit 250 is a moving part determined by the operation determining unit 240 at a time interval determined in step 120 is turned on or turned on at the point that the blinking means is turned off according to the moving state of the object. Decide on the point that is turned off (step 150).

When composed of three frames per second, when the movement of the fish is shown in the shape of the fish of FIG. 3, when moving from 310 to 320, the center portion of the body is relatively small in movement, and the tail portion. The moving area is larger. Therefore, the tail will be a moving part. At this time, the LED of the tail display part will turn off the LED before the tail passes and the area after the tail will turn off, and the tail will move at three times per second as the tail moves. The LED located in the area where the light passes is turned on. This will display the video.

At this time, instead of installing the LEDs in all the areas where the tail will move, three frames will be placed in one second, so only the parts corresponding to the areas of the tail will be placed in the area where the tail will be located every 1/3 seconds. Determined by the means positioning unit 250.

In addition, although not shown in FIG. 2, the same control as described above is executed by means of a flashing control unit to be included in the electronic display board on which the LED is installed to flash the LED.

As described above, when the device of FIG. 2 is operated through the method of FIG. 1 to determine the position of the LED as the blinking means, it is to determine the position where the LED is to be installed on the electronic display. Through this, the LED is installed to install the LED and the electrical wiring on the display board, and the location of the LED is also installed on the PCB mounted on the display board including all the electrical wiring such as a device for driving the LED including the LED.

Through the above process, the LED is not installed in all areas displaying the video, but the base can be installed only in the area where the moving object moves in the actual video, and also in the location where the moving object is moved at the required time interval. The invention provides.

Therefore, it can be seen that there is no problem in expressing a moving picture even if the LED is installed in the dot type, compared to the conventional case, and the same problem as the conventional case is solved.

In order to further reduce the number of LEDs, the present invention may be applied to only an area corresponding to the contour of a moving object, for example, the appearance of a fish while applying the present invention described above. The number also offers the advantage of being smaller.
