Abstract

A display apparatus includes a detector configured to detect an infrared ray emitted from a human body; a state signal generator configured to generate a state signal including at least one of a first state signal component indicating that the human body is approaching the detector and a second state signal component indicating that the human body is leaving from the detector in response to an intensity variance of the infrared ray detected with the detector; and a controller configured to start controlling an external device upon detecting the first state signal component from the state signal generated by the state signal generator but to stop controlling the external device upon detecting the second state signal component from the state signal.

Claims

1. A control apparatus comprising:

a detector configured to detect an infrared ray emitted from a human body;

a state signal generator configured to generate a state signal including at least one of a first state signal component indicating that the human body is approaching the detector and a second state signal component indicating that the human body is leaving from the detector in response to an intensity variance of the infrared ray detected with the detector; and

a controller configured to start controlling an external device upon detecting the first state signal component from the state signal generated by the state signal generator but to stop controlling the external device upon detecting the second state signal component from the state signal.

2. The control apparatus according to claim 1, wherein the controller stops controlling the external device when a first time elapses from a timing of starting controlling the external device.

3. The control apparatus according to claim 2, wherein the controller stops controlling the external device after a lapse of a second time, shorter than the first time, upon detecting the second state signal component.

4. A control method comprising the steps of:

detecting an infrared ray emitted from a human body;

generating a state signal including at least one of a first state signal component indicating an approach of the human body and a second state signal component indicating a deflection of the human body in response to an intensity variance of the detected infrared ray; and

starting controlling an external device upon detecting the first state signal component from the generated state signal but stopping controlling the external device upon detecting the second state signal component from the state signal.

5. A display apparatus comprising:

a detector configured to detect an infrared ray emitted from a human body;

a state signal generator configured to generate a state signal including at least one of a first state signal component indicating that the human body is approaching the detector and a second state signal component indicating that the human body is leaving from the human body in response to an intensity variance of the infrared ray detected with the detector;

a controller configured to start outputting a control signal upon detecting the first state signal component from the state signal generated by the state signal generator but to stop outputting the control signal upon detecting the second state signal component from the state signal;

a power source configured to generate power based on the control signal by receiving the control signal output from the controller; and

a display configured to carry out a display operation by receiving the power from the power source.

6. The display apparatus according to claim 5, wherein the controller starts outputting a control signal to switch the power source to an ON state from a standby state upon detecting the first state signal component or the second state signal component from the state signal, wherein the controller switches the power source to the standby state from the ON state after a lapse of a first time when the first state signal component is detected from the state signal, and wherein the controller switches the power source to the standby state from the ON state after a lapse of a second time, shorter than the first time, when the second state signal component is detected from the state signal.
