Abstract
A motion detection method utilized for a motion sensor includes: capturing a monitoring image; entering a recording mode when one intensity change value between the monitoring image and a pre-stored background image is higher than a first threshold and a trigger signal is received from an auxiliary sensor; and entering the recording mode when the intensity change value is higher than a second threshold before the trigger signal is received; wherein the second threshold is higher than the first threshold.
Claims8
A motion detection method utilized for a motion sensor, comprising:
- capturing a monitoring image;
- determining whether to enter a recording mode according to the monitoring image if it is determined that the monitoring image's quality is not under a disqualify threshold;
- and
- determining to enter the recording mode based on a result of a trigger signal from an auxiliary sensor being received if the monitoring image's quality is under the disqualify threshold.
A motion detection method utilized for a motion sensor, comprising:
- capturing a monitoring image;
- comparing the monitoring image and a pre-stored background image;
- and
- entering a recording mode if at least one first specific number of pixels becomes brighter from the pre-stored background image to the monitoring image, and at least one second specific number of pixels becomes darker from the pre-stored background image to the monitoring image.
