MONITOR DEVICE AND DYNAMIC OBJECT MONITORING METHOD
First Claim
1. A dynamic object monitoring method, executable by a processor of a server, the method comprising:
- setting types of monitored zones of a monitored region in a video frame captured by a network camera;
setting device parameters and sensitivity values corresponding to each of the monitored zones, wherein the sensitivity values refer to the quantity of preset values of predicted macro blocks in a monitored zone according to a prediction mode of the fourth generation motion picture expert group (MPEG-4) standard;
analyzing the predicted macro blocks of a current shooting frame retrieved by the network camera according to the prediction mode of the MPEG-4 encoding algorithm;
counting a number of the predicted macro blocks of each of the monitored zones;
determining whether a number of predicted macro blocks of a monitored zone is equal to or greater than a corresponding preset value;
when the number of predicted macro blocks of at least one monitored zone is equal to or greater than the corresponding preset value, determine a monitored zone where a dynamic object is located; and
adjusting the device parameters of the network camera as device parameters of the monitored zone where the dynamic object is located for recording.

Abstract
A dynamic object monitoring method including, setting types of monitored zones of a monitored region in a video frame captured by a network camera and setting device parameters and sensitivity values corresponding to each of the monitored zones. Analyzing the predicted macro blocks of a current shooting frame retrieved by the network camera according to the prediction mode of the MPEG-4 encoding algorithm. Counting a number of the predicted macro blocks of each of the monitored zones. Determining whether a number of predicted macro blocks of a monitored zone is equal to or greater than a corresponding preset value. A monitored zone is determined where a dynamic object is located. The device parameters of the network camera as device parameters of the monitored zone are adjusted where the dynamic object is located for recording.
