1. An electronic device, comprising:
- a detection unit for generating a detection signal;
a comparison unit for determining whether the detection signal exceeds a predetermined detection signal, if it is determined that the detection signal exceeds the predetermined detection signal, the comparison unit generates a first comparison signal indicating the proximity of an object to the electronic device;
a warning unit;
a timing unit for generating an elapsed time value in response to the first comparison signal, and further for keeping timing until the first comparison signal disappears;
a determination unit for determining whether the elapsed time value exceeds a predetermined value, if so, the determination unit generates a first determination signal; and
a control unit for generating a driving signal in response to the first determination signal;
wherein the warning unit generates a warning message in response to the driving signal.

Abstract
An electronic device includes a detection unit, a comparison unit, and a warning unit. The detection unit generates a detection signal. The comparison unit determines whether the detection signal exceeds a predetermined detection signal. If it is determined that the detection signal exceeds the predetermined detection signal, the comparison unit generates a first comparison signal indicating the proximity of an object to the electronic device. The warning unit sends a warning message in response to the first comparison signal.

9. An automatic warning method used in an electronic device, the method used for sending a warning message by a warning unit of the electronic device if others are in the vicinity of the electronic device, the method comprising:
-
generating a detection signal; determining whether the detection signal exceeds a predetermined detection signal; if it is determined that the detection signal exceeds the predetermined detection signal, generating a first comparison signal indicating the proximity of an object to the electronic device; generating an elapsed time value in response to the first comparison signal, and further for keeping timing until the first comparison signal disappears; determining whether the elapsed time value exceeds a predetermined value, if it is determined that the elapsed time value exceeds a predetermined value, generating a first determination signal indicating the proximity of an object to the electronic device; generating a driving signal in response to the first determination signal; and sending a warning message in response to the driving signal. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
