- various waves such as radio waves, ultrasonic waves, and infrared rays are received by the self position detection step, and the imaging device's state is detected based on the reception state, eg, intensity, waveform, frequency, interference state, etc.
- the own position is detected.
- the imaging device detects its own position wherever it can receive a wave, and imaging is performed when the imaging device is moved out of the area where it should be located.
- the self position detection step may be performed based on a plurality of different reception wave conditions. It is a method of detecting a position.
- the imaging device can detect its own position based on two or more types of received wave states different in frequency and waveform, based on the principle of triangulation and the interference state of the received wave, etc. It is possible to perform highly accurate position detection.
- the step of storing the authorized user identification information storing the authorized user identification information, and the acquisition from the user And a user determining step of determining whether or not the registered user identification information matches the authorized user identification information, wherein the imaging operation limiting step is the user determining step acquired from the user.
- the method does not limit the imaging operation of the imaging unit.
- the matching of the regular user identification information stored in advance in the regular user identification information storage stage with the user identification information acquired from the user is determined by the user determination stage. Will take place.
- the imaging operation restriction stage determines the current position of the imaging apparatus (self position) regardless of the imaging operation restriction stage.
- the imaging device is controlled so as not to always limit the imaging operation of the imaging unit.
- an effect is obtained that an authorized user can always perform imaging without being disturbed by the imaging operation even when moving the imaging device.
- control program of an imaging device is a computer program for causing a computer to function as each part of the imaging device.
- a computer readable recording medium recording the control program of the imaging device is a computer readable recording medium recording the control program for causing a computer to function as each part of the imaging device. is there.
- control program for the imaging device read out from the recording medium has the effect that the imaging device can be realized by a computer.
- the imaging device since imaging becomes impossible when the imaging device is moved out of the area where it should be located, it can be prevented from being used for illegal photography that violates voyage and privacy.
- the imaging device since the imaging device can not be used even if it is stolen, the imaging device, the imaging system, the imaging device control method and control program, and the imaging device capable of reducing the risk itself for theft or unauthorized use.
