1. A motion detection method applied into an image sensor device, comprising:
capturing a plurality of monitoring images through the image sensor device;
generating a plurality of regions of interest (ROIs) for each of the plurality of monitoring images;
receiving a user's feedback in favor of at least one region of interest (ROI);
selecting at least one ROI corresponding to a highest priority in priority levels of the plurality of ROIs to be displayed to the user;
transmitting a first notification to the user to notify the user of a first motion event occurring within a first ROI according to a first notification mode; and
transmitting a second notification to the user to notify the user of a second motion event occurring within a second ROI according to a second notification mode;
wherein the first notification mode is more urgent than the second notification mode when a priority level of the first ROI is higher than a priority level of the second ROI.
