Method for communications and game device
According to a game system, the communication period between a radio controller serving as a slave and a game device serving as a master can be made variable in a power saving mode. In a scene which requires a certain real-time level, the communication period is shortened, while in a scene which does not require a certain real-time level, the communication period is elongated. This variability of communication period as appropriate in the power saving mode can reduce power consumption without degrading the game characteristic.
1 . A method for wirelessly communicating information between a game device and a controller for the game device, the information being reflected on a game image to be displayed on a display, wherein
a communication period is variably set with respect to a level of real-time requirement.
2 . The communication method according to claim 1 , wherein the communication period is variably set with respect to a frame rate of the game image, the frame rate serving as the level of real-time requirement.
3 . The communication method according to claim 1 , wherein the communication period is set during a power saving mode.
4 . The communication method according to claim 1 , wherein the communication period is set according to a type of the game image, a title of the game, or a genre of the game.
5 . The communication method according to claim 1 , wherein the communication period is set based on a delay that is permitted in reflecting the information sent from the game device controller on the game image, thereby reducing power requirements of the game device controller.
6 . The communication method according to claim 1 , wherein the communication period is changed between during a setting mode of a game and during a play of the game.
7 . The communication method according to claim 1 , wherein a default value for the communication period is preset, and the communication period is determined by selecting from among a mode in which the default value is used for the communication period and a mode in which the communication period is variably set.
8 . The communication method according to claim 1 , wherein the communication period is set based on an instruction from a user.
9 . The communication method according to claim 8 , wherein the communication period is set, thereby allowing the user to set a response speed of a game character.
10 . A communication method for communicating information between a master and a slave, the information being reflected on an image to be displayed on a display, wherein
a communication period is variably set with respect to a frame rate of the image.
11 . The communication method according to claim 10 , wherein the communication period is set during a power saving mode.
12 . The communication method according to claim 10 , wherein the master and the slave are wirelessly connected to each other, and the slave is a battery-powered portable terminal.
13 . The communication method according to claim 10 , wherein the communication period is set according to a type of the image to be displayed.
14 . The communication method according to claim 10 , wherein the communication period is set based on a delay that is permitted in reflecting the information sent from the slave on the image, thereby reducing power requirements of the slave.
15 . A game device for wirelessly communicating information with a controller for the game device, the information being reflected on a game image to be displayed on a display, wherein
a communication period is variably set with respect to a frame rate of the game image.
16 . The game device according to claim 15 , wherein the communication period is set in a power saving mode.
17 . The game device according to claim 15 , wherein the communication period is set based on an instruction from a user.
18 . The game device according to claim 17 , wherein the communication period is set, thereby allowing the user to set a response speed of a game character.
19 . A program for allowing a computer to realize
a function for variably setting a communication period with respect to an image frame rate, and
a function for using the communication period having been set to communicate information being reflected on an image to be displayed on a display.
