Abstract
Official abstract text for this publication.
A computing system displays current real-time images of an area monitored by a camera. The computing system includes a motion detection unit. The motion detection unit determines a number of varied pixels in the real-time image compared with a previous image, and to determine a ratio of pixels of the number of the varied pixels to a total number of pixels in the real-time image. If the ratio is greater than a predefined number, the computing system increments an abnormal pixel count by one. If the abnormal pixel count is greater than a maximum abnormal pixel number, the computing system starts an alarm device connected to the computing system.
First claim
Opening claim text (preview).
What is claimed is: 1. A computing system, comprising: a storage system; at least one processor; and one or more programs being stored in the storage system and executable by the at least one processor, the one or more programs comprising: an obtaining module operable to read a current real-time image of an area captured by a camera; a control module operable to control a motion detection unit of the computing system to determine a number of varied pixels in the current re…
