Patent ID: 8498531

Claim:
A processor for a portable apparatus, wherein the portable apparatus comprises a plurality of types of sensors, said types of sensors including an image sensor, wherein said portable apparatus is operable in a plurality of powered operational states, said powered operational states including a first operational state and a second operational state, and an image capturing operation is performable in the first operational state, wherein said processor is configured to be connected to said sensors, wherein said processor includes one or a plurality of control units, at least one of said control units having a variably controllable operating frequency, wherein said processor is to control said portable apparatus to change its operational state from the second operational state to the first operational state and supply power to one or a plurality of components of the portable apparatus including said image sensor which is powered-off in the second operational state when receiving a first signal representing an activation of the image capturing operation in the second operational state according to a result of output of one or a plurality of said sensors, wherein said processor is to operate said portable apparatus to control a time-out from the first operational state to a monitoring state and to make said one or a plurality of components power off when there is not a second signal detected, wherein said change of operational state is performed with background processing, wherein said operating frequency can be lowered so that power consumption of said one of the control units can be close to almost zero.
