First Claim
Patent Images
1. A method of displaying a plurality of portions of a unified picture on multiple spatially adjacent displaying devices comrpises the steps of:
- (a) controlling each of said displaying devices indivdiually while maintaining a synchronized relation among displays provided thereon,(b) dividing the unified picture into a plurality of image portions, each of said portions corresponding to a respective one of said displaying devices, storing each of said image portions as data representing a plurality of picture elements in a memory,(c) inputting said picture elements data stored in said memory to said displaying devices,(d) said step of maintaining a synchronized relation comprising the further step of substantially simultaneously reading from memory picture element data for corresponding locations on each of said plurality of image portions for CRT screens of different ones of said displaying devices and(e) wherein said inputting step comprises the step of distributing the picture element data to said corresponding displaying devices.

Abstract
A wide picture with on-the-scene feeling is displayed on multiple CRT screens by using a method which is suitable for video game machines to enhance a player'"'"'s satisfaction. Data is read from a static memory and from a dynamic memory and is displayed in synchronism at corresponding points of the CRT'"'"'s.

-
(a) controlling each of said displaying devices indivdiually while maintaining a synchronized relation among displays provided thereon, (b) dividing the unified picture into a plurality of image portions, each of said portions corresponding to a respective one of said displaying devices, storing each of said image portions as data representing a plurality of picture elements in a memory, (c) inputting said picture elements data stored in said memory to said displaying devices, (d) said step of maintaining a synchronized relation comprising the further step of substantially simultaneously reading from memory picture element data for corresponding locations on each of said plurality of image portions for CRT screens of different ones of said displaying devices and (e) wherein said inputting step comprises the step of distributing the picture element data to said corresponding displaying devices. - View Dependent Claims (22)

2. A method of displaying a plurality of portions of a unified picture on multiple spatially adjacent displaying devices comprising the step of:
-
(a) controlling each of said displaying devices individually while maintaining a synchronized relation among displays provided thereon, (b) dividing the unified picture into a plurality of image portions, each of said portions corresponding to a respective one of said displaying devices, storing each of said image portions as data representing a plurality of picture elements in a memory, (c) inputting said picture elements data stored in said memory to said displaying devices, (d) said step of maintaining a synchronized relation comprising the further step of substantially simultaneously reading from memory picture element data for corresponding locations on each of said plurality of image portions for CRT screens of different ones of said displaying devices and (e) wherein said inputting step comprises the step of distributing the picture element data to said corresponding displaying devices, (f) rearranging the picture elements data stored in said memory into picture element units ordered according to a raster scanning sequence for storage in a second memory before distribution to said displaying device, (g) said rearranged step comprising the further steps of; (i) storing picture elements data belonging to even numbered raster lines of said raster scanning sequence in an even raster memory and (ii) storing picture elements data belonging to odd numbered raster lines of said raster scanning sequence in an odd raster memory. - View Dependent Claims (4, 23)

3. A method of displaying a unified picture on multiple displaying devices comprising the steps of:
-
(a) controlling each of said displaying devides individually while maintaining a synchronized relation among displays provided thereon, and (b) storing picture elements data in consecutive blocks of a memory, (c) inputting said picture elements data stored in said memory to said displaying devices, (d) said step of maintaining a synchronized relation comprising the further step of substantially simultaneouly reading picture element data for corresponding points of CRT screens of different ones of said displaying devices from said memory and (e) wherein said inputting step comprises the step of distributing the picture element data to corresponding displaying devices, (f) rearranging the picture elements data stored in blocks in said memory into picture element units ordered according to a raster scanning sequence for storage in a second memory before distribution to said displaying device, (g) said rearranging step comprising the further steps of; (i) storing picture elements data belonging to even numbered raster lines of said raster scanning sequence in an even raster memory and (ii) storing picture elements data belonging to odd numbered raster lines of said raster scanning sequence in an odd raster memory, (h) wherein each of said storing steps further comprises the steps of; (i) storing data of picture elements having even numbered dots in an even dot memory and (ii) storing data of picture elements having odd numbered dots in an odd dot memory, wherein said even dot memory and said odd dot memory are provided in each of the even raster memory and the odd raster memory. - View Dependent Claims (5)

6. A wide display system for displaying a unified image comprised of at least one of a static image and a dynamic image on a wide screen comprising:
-
(a) a plurality of individually controlled display device means, (b) means for synchronizing said plurality of display device means to provide sychronized displays thereon, (c) means responsive to rate of of change of image elements for identifying static image elements, defined as image elements changing at rates of change below a predetermined rate, and dynamic image elements, defined as image elements changing at rates of change above said predetermined rate, (d) static image processing means for displaying said static image elements, (e) dynamic image processing means for displaying said dynamic image elements, and (f) said identifying means sending said static and dynamic image elements identified thereby to said static and dynamic image processing means, respectively, and (g) means for combining said static and dynamic image elements respectively processed by said static and dynamic processing means into combined images displayed by said plurality of display device means. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
