Electronic apparatus capable of being waked up through detecting motions

摘要

An electronic apparatus including a plurality of sensors, an application processor, and a micro-processor is provided. The plurality of sensors is configured to generate at least one sensing signal. The application processor is configured to execute an application procedure according to a sensing-merged signal. The micro-processor is coupled between the plurality of sensors and the application processor, and is configured to generate the sensing-merged signal according to the at least one sensing signal. By utilizing the electronic apparatus, not only power can be saved, but also the elasticity for choosing sensor chip vendors can be improved.

1. An electronic apparatus capable of being waked up through detecting motions, comprising:
a plurality of sensors configured to generate at least one sensing signal, wherein the plurality of sensors comprises an accelerometer; an application processor configured to execute an application procedure according to a sensing-merged signal; a micro-processor coupled between the plurality of sensors and the application processor, wherein the at least one sensing signal generated by the accelerometer is used for controlling, enabling and disabling of the micro-processor, wherein the micro-processor is configured to generate the sensing-merged signal according to the at least one sensing signal, wherein when the micro-processor detects that the at least one sensing signal generated by the accelerometer is at high level, the micro-processor is enabled and is configured to compute the at least one sensing signal according to an algorithm to generate the sensing-merged signal; and a display module, wherein the application processor in a sleep mode turns off the display module; wherein the micro-processor generates the sensing-merged signal for waking up the application processor from the sleep mode, wherein the application processor compares the sensing-merged signal to see whether the sensing-merged signal corresponds to a specific gesture or not while the display module is turned off; and wherein under a condition that the sensing-merged signal corresponds to the specific gesture, the display module is enabled and enters an unlocked status automatically.
