A radio communication terminal receives position information showing a position of another radio communication terminal. The radio communication terminal obtains, from the position information, a terminal ID of the radio communication terminal, and a beacon ID for identifying the predetermined location nearest to the radio communication terminal. The radio communication terminal accepts the predetermined location designated by a user. The radio communication terminal determines as a communication partner terminal, the other radio communication terminal that is nearest to the accepted predetermined location based on the terminal ID and the beacon ID. The radio communication terminal performs communication with the determined communication partner terminal.

Radio communication terminal and radio communication method

A master terminal transmits sound waves that are a synchronization signal from a speaker to a slave terminal at random time intervals. Upon acquiring the sound waves that are the synchronization signal by microphone, the slave terminal promptly transmits a response signal through wireless communication to the master terminal. The master terminal receives the response signal and a terminal ID transmitted from the slave terminal. The master terminal receives the response signal multiple times and determines whether time intervals when synchronization signals were transmitted and time intervals when response signals were received match. When the synchronization signal time intervals and the response signal time intervals match, the master terminal recognizes the slave terminal that transmitted response signals at time intervals matching the synchronization signal time intervals as a wireless communication connection target. Slave terminals that transmitted response signals at time intervals not matching the synchronization signal time intervals are excluded from wireless communication connection targets.

A sensor obtains an angular rate of a stick member. A sound source map includes plural areas disposed in a virtual space. CPU presumes a direction of a turning axis of the stick member based on the angular rate obtained by the sensor, while a user is operating the stick member, calculates an angular rate of a top of the stick member based on the angular rate obtained by the sensor with the angular rate in the longitudinal direction of the stick member removed, calculates a position of the holding member in the virtual space after a predetermined time, based on the recent direction of the turning axis of the stick member and recent angular rate of the top of the stick member, and sends a sound generating unit a note-on event of a musical tone assigned to an area corresponding to the calculated position among the plural areas.

A CPU () of a musical instrument () calculates distances between central positions of a plurality of virtual pads () and a position of a marker unit (), by making adjustment such that a distance is shorter as a size associated with the virtual pad () is larger. The CPUidentifies a virtual pad () corresponding to the shortest distance among the distances calculated, as a virtual pad () for outputting sound. The CPU () identifies a tone corresponding to the virtual pad () for outputting sound by referring to set layout information.

An object of the present invention is to provide a musical performance device by which layout information, such as information regarding the arrangement of a virtual musical instrument set, can be quickly and easily changed during musical performance and whereby the variety of musical performance can be increased. In the present invention, a CPU identifies a musical tone associated with a virtual pad in an area where the position coordinates of a marker section are located in an image captured by a camera unit section at a shot timing by a drumstick section, and emits the identified musical tone. When the position coordinates of the marker section in an image captured at a shot timing are within the area of a control pad on a virtual plane, the CPU switches processing target set layout information to other set layout information among a plurality of set layout information.

An object of the present invention is to provide a musical performance device capable of changing layout information, such as information regarding the arrangement of a virtual musical instrument set, by an intuitive operation. In the present invention, when position coordinates detected at a shot timing are within one of the areas of a plurality of virtual pads, a CPU designates a virtual pad in this area as a target of positional change. Then, the CPU determines a position where the virtual pad designated as a target of positional change is placed by this positional change, based on position coordinates detected at shot timings, and changes the position of the virtual pad designated as a target of positional change to the determined position.

A performance apparatus prevents a player's unintentional motion from being detected as a playing, thereby generating no sound, when the player plays a virtual musical instrument. The performance apparatus has a player operated stick, a ROM for storing layout information, which correlates plural areas set on a virtual plane to tone colors, respectively, an image sensor for continuously taking pickup images of a subject including the stick, and a CPU for calculating a difference image between a first pickup image and a second pickup image taken prior to the first pickup image and for detecting an operating position of the stick based on the difference image. A CPU refers to the ROM to specify a tone color correlated to the area corresponding to the operating position detected by the CPU. And a sound source generates a tone of the tone color specified by the CPU.

An object of the present invention is to provide a musical performance device by which the arrangement of a virtual musical instrument set is suitably changed based on the position of the instrument player, and whereby the instrument player need not play in an uncomfortable position. In the present invention, set layout information includes standard set layout information that serves as reference for the arrangement of a plurality of virtual pads, and a CPU judges whether an operation to form a square has been performed with a pair of drumstick sections. When judged that this operation has been performed, the CPU uniformly adjusts the arrangement of the virtual pads based on preset position coordinates on a captured image plane corresponding to the standard set layout information and the position coordinates of the drumstick sections on the captured image plane at the time of the operation to form a square.

A ROM in the control circuit of a color printer stores a threshold matrix. The individual elements of the threshold matrix correspond to print dots, the number of which is X.times.Y and which form 1 pixel in the original image. Values t (x, y) which are integral numbers not less than 0 are assigned one to each of the individual elements in a predetermined order. Using the threshold matrix, the CPU of the control circuit creates mask patterns for representing halftones. A value of 1 is subtracted from the tone number allotted to the tone of color of a pixel in an image to be printed, and the resultant value is substituted for a variable G. When a gradation for image data representing the pixel is given as 'g', the condition required for setting ON (transferring toner to print) the dot specified by the coordinates (x, y) in the pixel in the case of the gradation 'g' is expressed by the following formula (6):
