Abstract

A method of configuring and adjusting frame coverage for a rotatable camera is provided. The method comprises following steps: a rotatable camera shoots a monitoring environment with different angles to generate a plurality of region images; combining the region images into a panoramic image; receiving an image-selecting operation for selecting a monitoring place in the panoramic image; retrieving an rotating angle information corresponding to the selected monitoring place and corresponding the rotating angle information to a triggering condition; and rotating the rotatable camera according to the rotating angle information for the current frame coverage of the rotatable camera to comprise the monitoring place when determining the triggering condition is satisfied.

Claims
