Description

  The present invention relates to a technique for displaying continuous video data without joints using a plurality of display devices.

  An information processing apparatus such as a personal computer is often used on a multi-display such as a multi-monitor.

  When a plurality of monitors are connected in parallel to receive and display video data or the like as a multi-monitor, the so-called joint portion of each monitor becomes a break in the video and the like, so it is necessary to connect them smoothly. .

  Therefore, there was a technique to solve the problem by placing a Fresnel lens in front of the image and enlarging the entire image. That is, referring to FIG. 4, in the left portion of the displayed image, the “A” and “B” portions are reduced to the “A ′” and “B ′” portions and reduced by the Fresnel lens. “A ′” and “B ′” as a whole were enlarged. In addition, the same processing is performed on the right portion of the video to be displayed.

In addition, as a related technology, the liquid crystal display structure is not directly proportional to the size of the size, but in order to cope with an exponential failure rate increase, small displays are arranged in parallel, and apparently large displays A technique to be realized has been proposed (see, for example, Patent Document 1). As shown in FIG. 3C of Patent Document 1, the configuration is such that the frame portion is apparently eliminated by arranging the transparent flat plate so as to create a composite screen.

That is, referring to FIG. 5, in the left portion of the video to be displayed, the “A” and “B” portions were uniformly reduced and then enlarged.

  The present invention has been made in order to solve the above-described problems. When a plurality of display devices are arranged and an apparently large continuous video is simply displayed, the display unit has no joints and is high. It is an object of the present invention to provide a display device and a data display method capable of obtaining a quality image.

  The display device of the present invention reduces a part of input data so as to fill a joint portion between adjacent monitors, enlarges only the reduced portion of the data by an enlargement means, and outputs the output data. The portion that has not been reduced is directly output data, and the output data is displayed.

The data display method of the present invention includes a step of reducing a part of input data so as to fill a joint portion between adjacent monitors,
Only the data of the reduced portion is enlarged by an enlargement means to output data, and the portion of the input data that has not been reduced is used as output data,
And displaying the output data.

  According to the present invention, when a plurality of display devices are arranged and an apparently large continuous video is simply displayed, a high-quality video without a joint on the display unit can be obtained.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a conceptual diagram of a display device according to the present embodiment.

  Referring to FIG. 1, the left portion of the displayed video is divided into “A” and “B”. The portion “A” is not subjected to reduction processing or enlargement processing using a lens or the like. Therefore, image degradation due to reduction / enlargement does not occur, and a high-quality video can be secured for this portion. On the other hand, the portion “B” is reduced by image processing in consideration of the joint portion between adjacent monitors and reduced to the portion “B ′”. Thereafter, the portion “B ′” is enlarged by a lens or the like. Will be displayed.

  Further, referring to FIG. 1, the right portion of the video to be displayed is divided into “D” and “C” as in the left portion. The portion “D” is not reduced or enlarged by a lens or the like. Therefore, image degradation due to reduction / enlargement does not occur, and a high-quality video can be secured for this portion. On the other hand, the portion “C” is reduced by image processing in consideration of the joint portion and reduced to the portion “C ′”, and then the portion “C ′” is displayed after being enlarged by a lens or the like. The

  Eventually, the image to be displayed becomes a continuous image with the joints filled.

Next, the structure of the display device according to the present embodiment will be described with reference to FIG.
FIG. 2 is a configuration diagram of the display device according to the present embodiment as viewed from above.

An LCD (Liquid Crystal Display) panel 1 is a part that displays an input image as it is through a space 4.
An LCD (Liquid Crystal Display) panel 2 is a portion that displays an input image in a reduced size.
The magnifying lens 3 has a function of enlarging the reduced video data. It may be realized by a concave lens or the like. Note that the magnification at which the video data is enlarged depends on the accuracy and performance of the lens.
The acrylic plate 5 is a part that displays the input image as it is through the space 4.
The acrylic plate 6 is a portion that is displayed by enlarging the reduced portion of the input image.
The frame 7 of the LCD panel corresponds to a so-called joint.

  FIG. 3 is a functional block diagram of the display device according to the present embodiment. 3 is an information processing apparatus controlled by a CPU or the like, and includes an input unit 11, a data sorting unit 12, a storage unit 13, a reduction unit 14, and an enlargement unit. 15 and an output unit 16.
