Classification: CPC A  G  H | IPC A  G  H

Claim 3:
4. The imaging apparatus according to claim 2,
wherein the processor is configured to restrict the maximum amount of the irradiation light of the light source to less than or equal to a first light amount by executing the power-saving control,
the processor is configured to temporarily set the maximum amount to a second light amount greater than the first light amount and temporarily set an amount of the irradiation light of the light source to a third light amount greater than the first light amount and less than or equal to the second light amount after a second period elapses from a time point of starting the power-saving control,
the processor is configured to compare first brightness with second brightness,
the first brightness is the brightness before the amount of the irradiation light of the light source becomes the third light amount,
the second brightness is the brightness when the amount of the irradiation light of the light source becomes the third light amount,
the processor is configured to determine whether or not the brightness meets a third condition,
the third condition represents that the second brightness is greater than the first brightness and the difference between the first brightness and the second brightness is greater than or equal to a third threshold value, and
the processor is configured to determine that the imaging device has gone into the space when the brightness meets the third condition.
