Abstract: An image processing system includes a dual lens module and a processor. The dual lens module captures a pair of images. The processor generates a depth map of the pair of images. The processor generates a pixel depth distribution histogram according to the depth map. The processor calculates a pixel depth mean and a pixel depth variance according to the pixel depth distribution histogram. The processor determines whether the pixel depth mean is within a distance range and determines whether the pixel depth variance is smaller than a first threshold or larger than a second threshold, so as to determine that the dual lens module is situated in a normal state or an abnormal state.

Abstract: A visitor grouping method determines whether different visitors belong to an identical group according to a distance between the visitors and an initial position of the visitors in an image sequence, so as to analyze a proportion of number of individual visitors to number of grouped visitors. Furthermore, the visitor grouping method may further determine whether two groups belong to an identical group according to a distance between the groups and an initial position of the groups in the image sequence. Moreover, the visitor grouping method may determine whether a child group exists and then merge the child group with other groups. Accordingly, a specific site may design the display content and manner with respect to the properties of the visitors, so as to enhance service quality and operating efficiency.

Abstract: An image capture system includes a first image capture device, a second image capture device and a processing device, and the processing device is electrically connected to the first image capture device and the second image capture device. The first image capture device is configured to capture a first image, and the second image capture device is configured to capture a second image. The processing device is configured to receive first information transmitted from the first image capture device and second information transmitted from the second image capture device, and determines whether the first image and the second image have a same object based on the first information and the second information. If the processing device determines that the first image and the second image have the same object, the processing device synchronizes timestamps of the first image and the second image according to an event of the object.
