Abstract: A system for capturing images of a person at a checkpoint including at least one image capture means for recording images of the person, a processing means to select a still image of the person from the recorded images, a control means for adding data to the still image and storage means for storing the still image and the data.

Abstract: A system for determining a key frame of an image sequence wherein the key frame includes the clearest image of the face of a person from the image sequence, the system included an image input means for receiving the image sequence of the person and a processing means for identifying the face of the person in each frame of the image sequence and then determining which frame is the clearest image of the person's face.

Abstract: A network camera apparatus is disclosed including an image requisition unit which obtains an analog signal of an image and converts this into digital format; an image compression unit which utilizes standard image compression techniques (JPEG, MJPEG) to decrease the data size; an image processing unit which analyzes the compressed data of each image, detects motion from compressed data, and identifies background and foreground regions for each image; a data storage unit which stores the image data processed by the image processing unit; a traffic detection unit which detects the traffic amount of the network and decides the frame rates of the image data to be transmitted; and a communication unit which communicates with the network to transmit the image data and other signals.
