Electronic apparatus and controlling method
An electronic apparatus includes: a processing unit which executes system processing; a detection unit which detects an object present within a predetermined detection range; an operation control unit which activates the operation of the processing unit when the object is detected within the predetermined range by the detection unit; and a detection range control unit which sets the predetermined detection range according to the operating state of the system processing.
1. An electronic apparatus comprising:
a processor coupled to a memory and configured to execute an operating system;
an infrared distance sensor configured to detect an object present within a detection range;
an embedded controller separate from the processor, the embedded controller being coupled to the infrared distance sensor, wherein the embedded controller is programmed to:
control a detection range of the infrared distance sensor to have a first field of view angle when the operation system is in a first operating state, and
control the detection range of the infrared distance sensor to have a second field of view angle when the operation system is in a second operating state with limited operating capabilities compared to the first operating state, and
the second field of view angle is narrower than the first field of view angle.
2. The electronic apparatus according to claim 1 , wherein the embedded controller is further programmed to:
control the detection range of the infrared distance sensor to have a first detection distance when the operation system is in the first operating state, and
control the detection range of the infrared distance sensor to have a second detection distance when the operation system is in the second operating state, and
the second detection distance is shorter than the first detection distance.
3. An electronic apparatus comprising:
a processor coupled to a memory and configured to execute an operating system;
an infrared distance sensor configured to detect an object present within a detection range;
an embedded controller separate from the processor, the embedded controller being coupled to the infrared distance sensor, wherein the embedded controller is programmed to:
control a detection range of the infrared distance sensor to have a first field of view angle while the object is being detected by the infrared distance sensor, and
control the detection range of the infrared distance sensor to have a second field of view angle while the object is not being detected by the infrared distance sensor, and
the second field of view angle is narrower than the first field of view angle.
4. The electronic apparatus according to claim 3 , wherein the embedded controller is further programmed to:
control the detection range of the infrared distance sensor to have a first detection distance while the object is being detected by the infrared distance sensor, and
control the detection range of the infrared distance sensor to have a second detection distance while the object is not being detected by the infrared distance sensor, and
the second detection distance is shorter than the first detection distance.
