Adaptive calibration ranging method and hand-held communication device

Abstract

The invention discloses a self-adaptive calibration ranging method and a hand-held communication device; the self-adaptive calibration ranging method comprises the following steps: start the work, start the distance sensing function by dialing a phone; perform the calibration work Adaptive distance sensing calibration steps; enable the distance sensor; apply to the central processing unit and enable the distance sensing interrupt entry; when the distance sensor has data changes, request the central processing unit to read the sensing value of the current distance sensor; The processor compares the currently read distance sensing value with the set close current threshold and far away current threshold; the central processing unit controls the screen display and touch screen functions according to the far away state or the close state; the call ends. After the distance measuring method of the present invention uses the self-adaptive calibration process, the threshold value of the distance sensor is self-adaptively adjusted, and is more accurate in the judging process of the approaching state and the faring state. It avoids the need to return to the factory for repair due to the abnormal use of the user, and saves the cost of the user and the manufacturer.

Description

Technical field [0001] The invention relates to a distance measuring method for communication equipment, and more specifically to a distance measuring method for self-adaptive calibration and a hand-held telephone communication equipment. Background technique [0002] With the development of the society in the new era, capacitive touch screens are widely used on mobile phones. When answering a call, the human face is very close to the touch screen, causing misoperation. Generally, a distance sensor is used to detect whether the phone is close to other objects according to the value measured by the distance sensor when other objects are close to the phone, and compare with a fixed distance threshold to perceive whether the phone is close to other objects. Lights and touch screen to avoid misoperation. With the different materials of the mobile phone, the increase in usage time, and the change of the use environment, the data read by the distance sensor will be inaccurate, so that...
