Abstract: A pedestrian detection method is applied to a monitoring camera. The pedestrian detection method includes forming a first detecting window on at least one monitoring frame via an object analysis function, utilizing a human form detection function to modulate the first detecting window for forming a second detecting window, analyzing the second detecting window via a human local detection function to mark an upper detecting window about a pedestrian on the monitoring frame, and determining whether to calibrate the second detecting window via analysis of the upper detecting window.

Abstract: A motion detection method is applied to a monitoring camera apparatus with motion detection function. The motion detection method includes analyzing a pixel value of each frame from a video stream changed over time, defining a first period and a second period having the pixel value greater than a triggering threshold respectively as a first event and a second event, comparing a time length of the first period with a filtering threshold to acquire time difference between an end point of the first period and a beginning point of the second period, comparing the time difference with a merging threshold, and acquiring relation between the first event and the second event according to comparison results of the filtering threshold and the merging threshold, so as to determine a detecting period of the motion detection function for actuation.

Abstract: An image identification method capable of preventing identification accuracy from affecting by illumination change is applied to an image identification device. The image identification method includes acquiring a first monitoring image and a second monitoring image respectively captured before and after the illumination change, dividing the first monitoring image and the second monitoring image into a plurality of areas, computing a pixel difference between each area of the second monitoring image and a corresponding area of the first monitoring image, setting pixel difference of the plurality of areas as at least one group, and determining whether to filter an area related to the at least one group according to distributed concentration of the at least one group.
