发明名称 Electronic device, signal compensation device and signal compensation method
摘要 An electronic device that prevents a failure caused by a temperature drift of an angular velocity sensor, and a signal compensation system and a signal compensation method for compensating for the temperature drift are provided. The present invention provides a mechanism including an angular velocity sensor that outputs a first signal in accordance with a rotational angular velocity. The device stores in advance data of a second signal normally output by the angular velocity sensor while in a stationary state, detects a stationary state and extracts the difference between the first and second signals when the stationary state is detected. The device thereby compensates for the first signal based on the extracted difference signal. A display unit in the device scrolls an image based on the compensated signal. This prevents a failure caused by the temperature drift of the angular velocity sensor.
