APPARATUS, METHOD, AND COMPUTER READABLE MEDIUM FOR MONITORING A NUMBER OF PASSENGERS IN AN AUTOMOBILE
First Claim
1. A monitor for installing inside an automobile to monitor a number of passengers in an automobile, wherein the monitor includes:
- an image capturing device, which successively captures a plurality of images in the automobile; and
a processing unit, which receives the images from the image capturing device to arrange an image sequence, wherein the processing unit includes an image dividing module, an image processing module, and a motion detecting module;
wherein the image dividing module divides each of the images into a plurality of recognition blocks;
wherein the image processing module compares the recognition blocks of consecutive images in the image sequence to acquire an image variance value;
wherein the motion detecting module has a threshold value and determines the recognition blocks as a human-present condition when the image variance value surpasses the threshold value.

Abstract
A monitor is utilized for installing inside an automobile to monitor a number of passengers in an automobile. The monitor includes an image capturing device, and a processing unit is connected to the image capturing device. The image capturing device successively captures a plurality of images in the automobile. The processing unit receives the images from the image capturing device to arrange an image sequence, wherein the processing unit includes an image dividing module, an image processing module, and a motion detecting module. The image dividing module divides each of the images into a plurality of recognition blocks, the image processing module compares the recognition blocks of consecutive images in the image sequence to acquire an image variance value, and the motion detecting module has a threshold value and determines the recognition blocks as a human-present condition when the image variance value surpasses the threshold value.
