Abstract: In order to generate, on a display screen, a natural-looking deformed image obtained by intentionally distorting an original image, a buffer 21 comprises an original image storage section 210 which stores an original image, and a model storage section 211 which stores a 3-D model, comprising a plurality of polygons, and having a shape in which at least a portion of a plane is distorted in 3-D space. A drawing processor 10 comprises an image pasting section 100, which reads an original image from the original image storage section 210, reads a 3-D model from the model storage section 211, and pastes the above original image, as a texture, onto the above 3-D model, and a deformed image drawing section 101, which, by writing to a frame buffer 213, draws on a monitor 22 a deformed image, which is an image of the above 3-D model onto which an original image has been pasted, as seen from a prescribed camera viewpoint.

Abstract: A video game device allows a game player to set a degree of difficulty of a technique to be performed by a play character by continuously hitting a pair of buttons in a controller. A command guiding unit guides the input of a command which causes the play character to perform a technique corresponding to the set degree of difficulty, and a stick-shaped controller allows the game player to input commands in accordance with the guide given by the command guiding unit. Upon completion of the performance of the technique by the play character, an evaluating unit evaluates the technique performed in accordance with the commands inputted by the game player.

Abstract: A video game device in which a game screen displayed on a monitor is controlled by operating an operation unit, the video game device comprises a character display control unit for displaying a player character in such a manner as to be rotatable together with a throwing object character and making such a display that the throwing object character is thrown in a specified direction by the player character when the operation unit is operated at a specified timing, and a guide display control unit for setting a guide display area in a partial area of the game screens, displaying a throwing mark in the guide display area which mark moves in response to a rotation of the throwing object character, and displaying an area mark specifying a throwing area of the throwing object character in association with the guide display area.

Abstract: A video game device is provided with a degree of difficulty setting unit 201h for setting a degree of difficulty of a technique to be performed by a play character by continuously hitting a C1-button 183h and a C2-button 183i provided in a controller 183, a command guiding unit for guiding the input of a command for causing the play character to perform a technique corresponding to the set degree of difficulty, a stick-shaped controller 183e provided in the controller 183 for inputting the command in accordance with the guide given by the command guiding unit, a landing setting unit 201j for setting landing finished upon completion of performance of the technique by the play character MA, and an evaluating unit 201k for evaluating the technique performed in accordance with a command inputting operation. Accordingly, a highly interesting and ingenuous game can be realized.
