A game controller includes a plurality of LEDs formed on the rear of a case. The plurality of LEDs are arranged two-dimensionally in its layout area. The game controller has a plurality of PWM control units which are provided inside the case and control the lighting of the plurality of LEDs, respectively. The PWM control units control the lighting of the LEDs based on a control signal from a game apparatus. The game apparatus acquires a captured image of the game controller, and acquires the position of the game controller in the captured image based on the positions of the LEDs in the captured image.

In a music information processing apparatus, a characteristic quantity acquiring unit reads out a music file from a music tune file storage unit and acquires a characteristic quantity of a music tune. A class value providing unit provides a class value for each music tune based on the characteristic quantity. The distribution acquiring unit forms a music tune assembly based on bibliography information read from the music tune file by a bibliography information acquiring unit, and acquires the distribution information of class values for each music tune assembly. The distribution information is stored into an analysis result storage unit, and an evaluation unit reads out distribution information based on user input, and evaluates the similarity between music tune assemblies or between a tune and a music tune assembly. An output unit recommends or reproduces a music tune assembly or a music tune according to the preference of a user.

The present invention provides a game system using LEDs in a controller. In a game system of the present invention, an image pickup apparatus captures the controller. The controller includes multiple input units for making an operation input to advance a game, and multiple LEDs for indicating a controller number set for the controller in a game application executed. A game apparatus accepts an operation input provided to the controller and reflects the operation input in the processing of a game application, acquires a captured image from the image pickup apparatus, acquires the position of the controller in the captured image based on the position of the LED in the captured image and reflects the acquired position information in the processing of the game application, and generates an image signal showing the result of application processing performed based on the operation input and acquired position information.

For an input interface apparatus for recognizing the motion of an object, there may be cases where the brightness of the object to be captured is insufficient, and thus, a camera takes an image of the object operated by the object, a depth position detector detects the position of the object based on captured frames, an action identifying unit identifies an action of the player based on a result on the detection of the object, an input receiving unit receives the action as an instruction to an input-receiving image displayed on a display, and in response to the action, an illumination control unit raises the brightness of the image projected on the display higher than that before the action is detected.

Image processing method and input interface apparatus

A player can be notified both visually and aurally that his/her action is recognized. A velocity vector-calculating unit calculates a velocity vector of the movement of an object manipulated by a player moving toward an assumable contact surface W by using an image of the movement of the player captured by a camera. A travel time calculating unit calculates the travel time required for the object to reach the contact surface W by using the velocity vector and a distance between the object and the contact surface W. A lag time acquisition unit acquires a lag time that sound output from a speaker takes to reach the player. A sound control unit allows the player to hear the sound substantially at the same time the object contacts the contact surface by outputting a predetermined sound after the time passes which is obtained by subtracting the lag time from the travel time.

Image-linked sound output method and device

An information processing device in which a data bus for establishing interconnection between a plurality of control operating units formed in a main processor is connected at one end to a graphic processor and at the other end to a main memory. Image frame data generated by the graphic processor is sequentially transferred through the data bus and stored into the main memory. The data bus satisfies R&#x2267;R&#x2267;Rand R&#x2267;R&#x2267;R, where Ris the data transmission rate from the main processor to the graphic processor, Ris the data transmission rate from the graphic processor to the main processor, Ris the data transmission rate between the main processor and the main memory, and Ris the rate to transmit a single image frame of data within a vertical blanking interval.

The present invention relates to a free-from surface creation method and apparatus thereof which can automatically determine such internal control points that allow a plurality of patches to form a smooth surface. Based on the four normal lines (N.sub.00, N.sub.01, N.sub.10, N.sub.11) to a quadrilateral patch A at its corners and on its four edges (E.sub.1, E.sub.2, E.sub.3, E.sub.4), reference normal lines at a plurality of points defined on each edge (E.sub.1, E.sub.2, E.sub.3, E.sub.4) are determined, and each reference normal line determined on the respective plurality of points are approximated to the normal line corresponding to the plurality of points which are defined on the edges of which are shared with the quadrilateral patch A and the adjacent patch. Therefore, the internal control points of the quadrilateral patch A are determined.

Disclosed is a shape data processing method illustratively for use with a CAD,CAM (computed aided design/ computer aided manufacturing) system. The method involves measuring the volume of a target product based on the shape data of that product. In operation, a virtual projection surface is established for the target object to be measured. The surface of the object is divided into small regions. A column portion is formed as an extension from each small region to the projection surface. The volume of the column portion is measured for each small region. The measured volumes are accumulated in accordance with the orientation of the normal vector to each small region. This method allows the volume of the target object to be measured easily and with precision even if the shape thereof is complex.
