Embodiment 1

[0047] Use Figure 1~ Figure 4 , the peripheral device, its control method, its main device, its control method, and its program according to Embodiment 1 of the present invention will be described.

[0048] First, the configurations of the main device and peripheral devices of the first embodiment will be described. FIG. 1 is a block diagram showing the configurations of a main device and peripheral devices according to Embodiment 1 of the present invention. In FIG. 1 , 101 is a main device, and 102 is a peripheral device. The main body device 101 has a display unit 111 , a control unit 112 , and an interface unit 113 . The peripheral device 102 has an interface unit 121 , a function block 122 , a power control unit 123 , a power profile profile register 124 , a power profile profile information memory 125 , and a peripheral device information register 126 . The functional block 122 has a functional unit 131 .

[0049] In Embodiment 1, the main device 101 is a computer, a...

Embodiment 2

[0078] With Figure 5, Figure 6 , the peripheral device, its control method, its main device, its control method, and its program according to Embodiment 2 of the present invention will be described.

[0079] First, the configurations of the main device and peripheral devices of the second embodiment will be described. 5 is a block diagram showing configurations of a main device and peripheral devices according to Embodiment 2 of the present invention. The difference from Embodiment 1 (FIG. 1) is that a functional unit is added to the peripheral device. Except for this, the main device and peripheral devices of the second embodiment are the same as those of the first embodiment. In FIG. 5 (Example 2), the same components as those in FIG. 1 (Example 1) are assigned the same reference numerals, and description thereof will be omitted.

[0080] In FIG. 5 , 101 is a main device, and 502 is a peripheral device. The main body device 101 has a display unit 111 , a control unit 11...

Embodiment 3

Abstract

A peripheral device receiving a command and power from a body device, wherein the power consumption can be reduced while maintaining a required function. The peripheral device comprises a functional unit that functions according to a command from the body device; a power control unit that controls the power consumption of the functional unit; a power profile information memory in which a power profile information list containing one or more pieces of power profile information is stored; and an interface unit that sends and receives the power profile information and a command about the functional unit to and from the body device. The interface unit sends the power profile information list to the body device in response to a request from the body device, and the power control unit controls the power consumption of the functional unit according to information selected from the power profile information received from the body device.

Description

technical field [0001] The present invention relates to a peripheral device inputting commands from a main device and supplying power from the main device, a control method thereof, a main device thereof, a control method thereof, and a program thereof. Background technique [0002] In recent years, with the popularization of portable information devices such as digital cameras and PDAs, not only personal computers but also portable information devices such as digital cameras and PDAs can share small peripheral devices. [0003] The main body device and peripheral devices of Conventional Example 1 are disclosed in Japanese Patent Application Laid-Open No. 62-217314. use Figure 9 , the main device and peripheral devices of Conventional Example 1 will be described. [0004] Figure 9 It is a block diagram showing the configuration of a main device having an I / O slot for connecting peripheral devices of Conventional Example 1. exist Figure 9 Among them, 901 is the main devi...
