Image capturing device and activation method therefor
First Claim
1. A portable apparatus having functions of image capturing and power management, the portable apparatus operable in powered operational states including first and second operational states, an image capturing operation being performable in the first operational state,said portable apparatus comprising:
- a touch sensor for detecting user'"'"'s touch,one or plurality of components including imaging capturing unit, the one or plurality of components consuming less power in the second operational state than in the first operational state, anda power supply section for supplying power to the one or plurality of components; and
said portable apparatus comprising a power management processing unit to which power from the power supply section is supplied through a power-supply line other than a power-supply line through which power from the power supply section is supplied to the one or plurality of components, the power management processing unit being configured to monitor a signal indicating user'"'"'s touch operation to the touch sensor in the second operational state, and when detecting a signal representing a user'"'"'s touch operation in the second operational state, to control the operational state change of the portable apparatus from the second operational state to the first operational state and to control supplying sufficient power to said one or plurality of components so that the one or more components is capable of working for the image capturing operation, andwherein the portable apparatus consumes power in the second operational state,the portable apparatus further comprising a control unit operable to monitor and process an operation input signal of said user'"'"'s touch operation, wherein said control unit is capable of receiving said signal representing said user'"'"'s touch operation from said touch sensor through serial communication.

Abstract
An image capturing device includes a first controller operable to control image capturing; an operation section including a switch; a detector operable to detect a change to an image capturing mode and to send a signal representing the change; a second controller operable to monitor and process the sent signal, the second controller having a power consumption less than that of the first controller; and a power supply operable to supply power to the first controller, the second controller, and a functional section of the device. When the second controller receives the signal sent from the detecting section in a power saving state in which power is supplied from the power supply to the second controller, the power saving state is changed to a power supplying state capable of image capturing by supplying power from the power supply to portions of the device including the first controller.
