Description

Description
A multi-panel plasma screen display and a compositing module therefor
Technical Field
This invention relates to a multi-panel plasma screen display and, in particular, to a compositing module therefor.
Background Art
Multi-panel plasma screen displays are large area displays assembled from individual plasma screens. They are used in situations where a large dimension display is required, such as in a conference hall or control room where the images on the screen need to be viewed at a distance.
A plasma panel suitable for assembly into a multi-panel plasma screen is manufactured and distributed by Orion PDP Co., Ltd, of 257 Gongdan-Dong, Gyung-Buk, Korea. The plasma panel is designed to display an image over practically the entire surface of the screen with only a small dead zone around the edge. When assembled there is only a 5mm wide seam between individual panels.
The above plasma panel has an aspect ratio of 16:9 and will display a 16:9 formatted input signal (e.g. PAL 16:9) without distortion of the image. Consequently when individual panels are stacked together in an nxn array (e.g. 2x2, 3x3, etc.) the 16:9 aspect ratio is maintained and the same image will display in a larger size but still without distortion.
However, a problem with multi-panel plasma screen displays of the above type arises when the aspect ratio of the display is markedly different from that of the input signal. Thus, as the ratio increases the resulting image becomes stretched and otherwise distorted and consequently is unsuitable for viewing. This is especially problematical when a moving image is to be displayed.
It is an object of the present invention to overcome the disadvantages of the multi-panel plasma screen display hereinbefore described.
Disclosure of Invention
Thus, the invention provides a multi-panel plasma screen display, comprising a plurality of plasma panels arranged in an array, means for managing the display characteristics, and means for inputting a moving image signal to the display, characterised in that, when the aspect ratio of the moving image signal to be inputted does not match that of the display, the moving image signal is manipulable in a compositing module to provide an input signal, the displayed image from which will fill the display with minimal distortion thereto.
An advantage of the multi-panel plasma screen display according to the invention is that the plasma panels making up a multi-panel plasma screen display can be arranged in an array that suits the location in which the display is to be located and the arrangement is not limited by considerations of its aspect ratio. Thus a linear array of plasma panels above a point of sale outlet could be used to display video advertisements relating to the business within or any other product or business outside that of the outlet.
The compositing module manipulates the moving image signal by applying a combination of adjustments thereto such as differential stretching across the screen display area, zooming or a combination thereof.
The compositing module for a particular array of plasma panels carries out a particular set of adjustments on a moving image signal having a particular aspect ratio. Examples of moving image signal formats are PAL 16:9, PA 4:3, Quicktime 800x600 movie (Quicktime is a trade mark of the Apple Corporation), Flash interactive content (1024x768) (Flash is a trademark of the Adobe Corporation).
It will be appreciated that some cropping of the original images is inevitable.
Preferably, the compositing module provides an input signal, which provides an image on the display, the dimensions of which image are not alterable by the display managing means following input thereof.
Usually, in known multi-panel plasma screen displays, the display management means will attempt to fill a pre-selected area of the display with the inputted image and this could lead to distortion of the resulting image. However, the input signal to the display, in accordance with the invention, overrides this function as the inputted signal has been formatted to fill the pre-selected area of the display before it is sent to the display.
In a further aspect of the invention there is provided a compositing module for a multi-panel plasma screen display, the compositing module comprising means for detecting the aspect ratio of the display, means for establishing the aspect ratio of a moving image input signal to the display, and means for manipulating the input signal to fit, where necessary, the aspect ratio of the display, such that in use the moving image input signal provides an image which is displayable on the display with minimal distortion.
The compositing module can be connected to the inputting means of the display or can be a separate device. Where a separate device is used the image signal to be inputted to the display can be manipulated and copied to a storage device for later use in the inputting means.
Brief Description of the Drawing
The accompanying Figure is a schematic representation of a multi- panel plasma screen display in accordance with the invention. Mode for Carrying Out the Invention
The invention will be further illustrated by the following description of an embodiment thereof, given by way of example only with reference to the accompanying Figure.
Referring to the Figure there is indicated, generally at 10, a multi- panel plasma screen display, having four plasma panels 11 arranged in a 4x1 array 12. A computer 13, which serves as a display managing unit, is connected to the array 12 by a cable 14. A moving image signal input unit 15 is connected to the array 12 by a cable 16. A compositing module 17 is connected to the input unit 15 by a cable 18.
Each plasma panel 11 has an aspect ratio of 16:9. Thus the resulting array 12 has an aspect ratio of 64:9.
In use, a moving image input signal on a storage medium (not shown) is inserted into the input unit 15. The aspect ratio of the input signal is keyed into the input unit 15 and the compositing module 17 applies a set of adjustments to the input signal using compositing tools. The resultant signal is inputted to the array 12 and will fill the screen with images which display minimal distortion.
The invention will be further illustrated by the following example.
Procedure for re-sizing PAL footage for display on a 4x1 multi- panel plasma screen display. PAL Footage is imported into the compositing module 17.
The sequence is adjusted from 720x576 @72dpi to 800x600 @72dpi.
A scaling adjustment, vertically by 400 % is applied while leaving the horizontal at 100%.
The area of footage that is in the original PAL area can be removed without affecting the image.
The final output movie is 800x600 @72dpi and is elongated to a ratio of 4:1 (4 units wide by 1 unit down), to match the aspect ratio of the array 12.
The resulting moving image signal is output with no compression.
The moving image signal is imported into Flash ™ and is compressed.
The Flash ™ executable file is outputted to the input unit 15 and is launched.
The result is that the original PAL footage plays on the 4x1 mult- panel plasma screen display with minimal or the least distortion thereto.
