In general, a digital moving picture display device is a device for displaying a digital moving picture corresponding to RGB data values as digital data. The digital moving picture is displayed by sequentially displaying unit images displayed in accordance with RGB data values of a plurality of unit frames .

On the other hand, when human beings recognize objects with the naked eye, they tend to feel the central part clearly. On the other hand, there is a tendency to feel increasingly blurred as to the portion far from the center. It is known that, through such a difference in sharpness between the center portion and the portion far from the center, people feel a stereoscopic effect or the like.

At this time, there is a demand for a moving image display device that increases the sense of reality that a human being actually feels with the naked eye.

For a better understanding of the present invention and its operational advantages, and the objects attained by the practice of the present invention, reference should be made to the accompanying drawings, which illustrate preferred embodiments of the invention, and the accompanying drawings. In understanding each of the figures, it should be noted that like parts are denoted by the same reference numerals whenever possible. Also, in the following description, numerous specific details, such as specific processing flows, are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without these specific details. Further, detailed descriptions of known functions and configurations that may be unnecessarily obscured by the gist of the present invention are omitted.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Rather, the embodiments disclosed herein are being provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.

1 is a block diagram illustrating a digital moving picture display apparatus according to an embodiment of the present invention. 2, the digital moving picture display apparatus of the present invention includes unit images UT_IMG (n) of first through n-th unit frames FR_1 through FR_n (MPIMG), which is composed of a plurality of moving pictures.

Referring to FIG. 1, the digital moving picture display apparatus of the present invention includes a display unit 100, a unique data value generator 200, and a data value transformer 300.

The display unit 100 includes a display area AR_DIS in which a plurality of pixels PIX are arranged, as shown in FIG. The display unit 100 displays the unit image UT_IMG in the first to nth unit frames FR_1 to FR_n according to its display RGB data value group GDISDAT in the display area AR_DIS).

At this time, the display RGB data value group (GDISDAT) includes pixel display RGB data values (PDISDAT) of the plurality of pixels (PIX). Here, each of the pixel display RGB data values PDISDAT is a digital data value, and RGB data values of R (red), G (green), and B (blue).

Each of the plurality of pixels PIX is driven by its own pixel display RGB data value PDISDAT so that the display area AR_DIS is provided with the display RGB of each of the first to nth unit frames FR_1 to FR_n A unit image according to the data value group (GDISDAT) is displayed.

As the first to n-th unit frames FR_1 to FR_n are progressively processed, the unit images of the first to n-th unit frames FR_1 to FR_n form the intended motion picture MPIMG do.

The unique data value generator 200 generates its own unique RGB data value group GNDAT for its own unit image UT_IMG in each of the first to nth unit frames FR_1 to FR_n . Here, the native RGB data value group GNDAT includes pixel-specific RGB data values PNDAT of the plurality of pixels PIX. At this time, the generation of the unique RGB data value group (GNDAT) in the unique data value generator 200 may be realized by various methods including reception from the outside or self generation.

The data value modification unit 300 modifies its own unique RGB data value group GNDAT in each of the first to nth unit frames FR_1 to FR_n to convert its own display RGB data value group GDISDAT ).

As shown in FIGS. 4A and 4B, each of the pixel display RGB data values (PDISDAT) includes RGB data values of the swing width WSW according to a predetermined rule from the corresponding pixel-specific RGB data values PNDAT , And is complementarily added to or subtracted from the unit frame FR_i and the (i + 1) th unit frame FR_ (i + 1) of the ith (where i is a natural number less than n).

At this time, the swing width WSW increases as the distance from the reference PSEN increases in the same direction. Preferably, the swing width WSW increases in a parabolic shape such as a quadratic function as the distance from the reference PSEN increases in the same direction.

Also, preferably, the reference (PSEN) is set to a pixel PIX located at the center of the display area PSEN.

On the other hand, for images appearing in two consecutive unit frames, the hue appears to depend on the average value of the pixel display RGB data value (PDISDAT), while the sharpness is known to blur as the swing width increases.

Accordingly, in the digital moving picture display apparatus of the present invention, the moving picture MPIMG in the reference (PSEN) maintains high sharpness. Further, the farther from the reference (PSEN), the lower the sharpness of the moving picture MPIMG.

Next, a digital moving picture display method of the present invention is described. 5 is a flowchart showing a digital moving picture display method according to the present invention.

Referring to FIG. 5 together with FIGS. 1 to 4, the digital moving picture display method of the present invention includes an inherent data value generating step S100, a data value transforming step S200, and a displaying step S300.

In the unique data value generation step S100, a unique RGB data value group GNDAT for the unit image UT_IMG of the unit frame UT_IMG is generated in each of the first to nth unit frames FR_1 to FR_n . At this time, the native RGB data value group GNDAT includes pixel-specific RGB data values PNDAT of the plurality of pixels PIX.

In the data value modification step S200, in the first to nth unit frames FR_1 to FR_n, the original RGB data value group GNDAT of its own is modified, and its display RGB data value group GDISDAT is transformed, Is generated. The display RGB data value group (GDISDAT) includes pixel display RGB data values (PDISDAT) of the plurality of pixels (PIX).

Each of the pixel display RGB data values (PDISDAT) is added or subtracted from the corresponding pixel-specific RGB data value (PNDAT) to an RGB data value of a swing width (WSW) according to a predetermined rule, Is complementarily added or subtracted in the (i + 1) th unit frame FR_ (i + 1).

In the display step S300, the unit image UT_IMG of the first to n-th unit frames FR_1 to FR_n according to its display RGB data value group GDISDAT is divided into the display area AR_DIS ).

In the digital moving picture display apparatus and method of the present invention, the moving picture MPIMG in the reference (PSEN) maintains high sharpness. Further, the farther from the reference (PSEN), the lower the sharpness of the moving picture MPIMG.

Thus, according to the digital moving picture display apparatus and method of the present invention, the actual feeling of reality is remarkably increased.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.

For example, it is apparent to those skilled in the art that the technical idea of the present invention can be implemented by the embodiment in which the swing width is gradually increased. It is also apparent to those skilled in the art that the technical idea of the present invention can be implemented by the embodiment in which the reference is set to a fixed area rather than a diagonal point.

Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
