Monitoring Camera Device and Related Region-based Motion Detection Method
First Claim
1. A region-based motion detection method capable of detecting motion of an object displayed on a frame, the region-based motion detection method comprising:
- dividing a current frame into a plurality of first template arrays;
dividing a first reference frame into a plurality of second template arrays;
acquiring characteristic values of one of the plurality of first template arrays and a corresponding second template array of the plurality of second template arrays;
comparing the characteristic value of the foresaid first template array with the characteristic value of the corresponding second template array by matching process; and
executing motion detection of the object displayed on the current frame according to a result of the matching process.

Abstract
A region-based motion detection method and a related monitoring camera device are applied to detect an object'"'"'s motion on a frame. The region-based motion detection method includes dividing a current frame into a plurality of first template arrays, dividing a first reference frame into a plurality of second template arrays, acquiring characteristic values of one of the first template arrays and a corresponding second template array, comparing the characteristic value of the foresaid first template array with the characteristic value of the corresponding second template array by matching process, and executing motion detection of the current frame according to a matching result.
