Abstract

The embodiment of the invention relates to a motion detection method and apparatus, and a mobile device. The method comprises the following steps: obtaining brightness data of each frame of data, and obtaining a brightness difference between a preset number of continuous frames of data according to the brightness data of each frame of data; obtaining sensor data of the mobile device and a standard deviation of the brightness of the frames of data; adjusting a motion detection threshold according to at least one of the standard deviation of the brightness of the frames of data and the sensor data; and if the brightness difference is greater than the motion detection threshold, judging that a moving object is detected. The accuracy of motion detection is improved.

Description

technical field [0001] The present invention relates to the field of motion detection, in particular to a mobile device-based motion detection method and device, and a mobile device.
