<p>PURPOSE:To detect a focusing distance and to know the approach of an object. CONSTITUTION:An intruder monitoring device consists of a lens part 1 where a lens is focused on a subject and also an optical image of the subject is formed, an image pickup part 2 where the optical image obtained through the part 1 is converted into the electric signals, an A/D conversion part 3 where the electric signals of the optical image are converted into the digital signals, a focus control part 4 where the focusing of the part 1 is carried out, a contour extracting part 5 where the contour signals of the optical image are extracted out of the digital signals based on the optical image, a comparison part 6 which compares the prescribed data with each other, an alarm part 7 where the voices, the display or a prescribed electric signal are outputted, a memory 8 which stores the focusing data, the contour data based on the optical image and the setting data, etc., and a control part 9 which controls the respective parts including the part 4, etc.</p> |
