Power-supply control device, image processing apparatus, power-supply control method, and computer-readable medium

摘要

A power-supply control device includes a transition section, a body-capable-of-movement detection section, a return control section, a reference-time-period setting section, a state determination section, and a correction section. The transition section shifts a state of an operation target section from one state to another state among a power-supply state and multiple types of non-power-supply states. The body-capable-of-movement detection section detects a body capable of movement. The return control section controls the transition section so as to return the state of the operation target section to the power-supply state. The reference-time-period setting section sets a reference time period. The state determination section checks a state of detection of the body capable of movement after the reference time period elapses. The correction section corrects the reference time period on the basis of detection position information.

1. A power-supply control device comprising:
a transition section that shifts a state of an operation target section to a power-supply state or one of a plurality of types of non-power-supply states, and that, in a case of shifting the state of the operation target section to a non-power-supply state, selects a non-power-supply state among the plurality of types of non-power-supply states and shifts the state of the operation target section to the selected non-power-supply state, the operation target section being a section which operates by receiving supply of power from a power source section, the power-supply state being a state in which power is supplied to the operation target section, each of the plurality of types of non-power-supply states being a state in which supply of power to the operation target section is interrupted, shifting from each of the plurality of types of non-power-supply states to the power-supply state taking a corresponding one of return time periods that are relatively different from one another; a body-capable-of-movement detection section that detects a body capable of movement including a user who intends to use the operation target section; a return control section that, when the body capable of movement is detected by the body-capable-of-movement detection section in each of the plurality of types of non-power-supply states, performs a return process of controlling the transition section so as to return the state of the operation target section to the power-supply state, the return process taking each of activation time periods from a time at which the return process starts to a time at which the return process finishes in a corresponding one of the plurality of types of non-power-supply states; a reference-time-period setting section that sets a reference time period on the basis of a longest activation time period among the activation time periods corresponding to the plurality of types of non-power-supply states, the reference time period being used for a time at which detection of the body capable of movement with the body-capable-of-movement detection section is performed again; a state determination section that checks a state of detection of the body capable of movement with the body-capable-of-movement detection section after the reference time period set by the reference-time-period setting section has elapsed from the time at which the return process started, and that determines whether the state of the operation target section which is the power-supply state is to be kept or the state of the operation target section is to be returned to one of the plurality of types of non-power-supply states by controlling the transition section; and a correction section that corrects the reference time period on the basis of detection position information concerning a position at which the body capable of movement is detected by the body-capable-of-movement detection section.
