Abstract: Amusement facilities for providing predetermined images to passengers inside a vehicle for amusement on the basis of a scenario while the vehicle (ride)(1) is moving in a predetermined course, wherein the course includes bright areas and dark areas, and acceleration/deceleration of the ride (1) is done at the boundaries of these areas. A video camera (11) provides images outside the vehicle to the passengers in the bright areas and images of a video disk player (34) are provided to the passengers in the dark areas. Further, sways are imparted by a motor (23) for rolling and a motor (24) for pitching to the ride (1) in accordance with scenarios. These images, acceleration/deceleration and sway give the passengers an illusion as if they had moved over a longer distance than an actual distance in the dark areas.

Abstract: Provided is a game screen display controlling method comprising the steps of displaying a first game screen obtained from a first projection of a virtual 3-D space; comparing the priority of the first projection with the priority of a second projection correlated with a predetermined area when there is a predetermined positional relationship between a character who moves in the virtual 3-D space and the predetermined area set within the virtual 3-D space; and displaying a second game screen obtained from the second projection of the virtual 3-D space when the priority of the second projection is higher than the priority of the first projection. Thereby, the invention allows game pictures for effectively rendering the virtual 3-D space to be presented corresponding to the situation of the game.

Abstract: A virtual image generation apparatus comprising shape data memory for storing shape data pertaining to obstacles and the like, position data specifier for specifying position data for the subjects, overlap determiner for determining, on the basis of shape data and position data, whether or not physical objects located between a visual point and a subject should overlap and be visible from the visual point, and image generator for generating virtual images wherein physical objects are processed by prescribed show-through processing (mesh processing, translucent processing, or the like) when it is determined that an overlapping state exists. Accurate overlap determinations can be made using a vector that extends from the visual point towards an object and a vector that extends from an obstacle towards the object, and mesh processing or other show-through processing used to produce a suitable display of the subject obscured by a physical object.

Abstract: A method for compressing and decompressing moving picture information wherein a key signal is correctly reproduced and coding is efficiently carried out, and a video signal processing system for implementing the method. At the time of coding a video signal, conversion is carried out for make large a distance between an ordinary digitized video signal and a key signal indicative of whether an image indicates background or foreground for data compression. At the time of decoding the coded video signal, the video signal and key signal of the decompressed image are separated based on a predetermined threshold and reverse conversion opposite to the coding mode is carried out. Since the coding is carried out with the ordinary video signal separated from the key signal, the video signal and the key signal can be separated by a suitable threshold from the compressed and then decompressed image and thus the video signal and key signal can be correctly reproduced.

Abstract: Provides a game processing apparatus capable of getting players more excited about playing games. For that reason, the game processing apparatus of the present invention processes games on the basis of players' operating signals, and is equipped with processing circuits (10), which process the above-mentioned games on the basis of operating signals supplied from input devices (2b) operated by the players, and which generate the image data for these games. When an operating signal equivalent to a player's victory declaration is input from an input device (2b), the processing circuits (10) process subsequent operating signals input by the player as invalid signals until a prescribed condition is achieved.

Abstract: According to the image processing method, when the number of shadow polygons existing between a depth position of pixels of ordinary polygons subject to shadowing and an infinite position is counted and that number is an odd number, those pixels are unconditionally judged to be positioned inside a region of shadow volume. Therefore, regions to undergo shadowing can be efficiently detected by judging whether the number is an odd number or an even number at all pixel positions.
