Abstract

A functional device includes a light sensor for outputting a signal control signal relative to received light, a temperature sensor for outputting an additional control signal relative to an ambient temperature, a control means for controlling the signal control signal, and an output means for outputting a sensory signal perceivable by a sensory organ based on the signal control signal. The control means controls the signal control signal by using the additional control signal.

Claims

1. A functional device comprising:

a light sensor for outputting a signal control signal relative to received light;

a temperature sensor for outputting an additional control signal relative to an ambient temperature;

a control means for controlling the signal control signal; and

an output means for outputting a sensory signal perceivable by a sensory organ based on the signal control signal,

wherein the control means controls the signal control signal by using the additional control signal.

2. The functional device according to claim 1,

wherein the output means includes a backlight of a liquid crystal panel, and

the sensory signal includes light emitted from the backlight.

3. The functional device according to claim 1,

wherein the output means includes a sound generation device, and

the sensory signal includes sound generated by the sound generation device.

4. The functional device according to claim 1,

wherein the output means includes a vibration generation device, and

the sensory signal includes vibration generated by the vibration generation device.

5. A method for controlling a sensory signal comprising steps of:

providing a first sensor for outputting a signal control signal relative to received light;

providing a second sensor for outputting an additional control signal relative to an ambient temperature;

providing a control means for controlling the signal control signal; and

providing an output means for outputting the sensory signal perceivably for a sensory organ based on the signal control signal,

wherein the control means controls the signal control signal by using the additional control signal.
