SIGHT RECOGNITION ASSEMBLY ALLOWING A SAFE DISTINCTION BETWEEN DIFFERENT PARTS OF A DIASCOPIC SIGHT DURING THE DEVELOPMENT OF A VIDEO CAMERA

摘要

P FOR THE MEASUREMENT AND CORRECTION OF SPACE ERRORS AND NOISE LEVELS, A TEMPERATURE WINDOW OF MARKING 16 IS PROVIDED FOR POSITIVELY LOCATING THE WHITE-BLACK TRANSITIONS OF COARSE MARKS 14 SELECTIVELY PLACED IN THE SIGHT AND DISTINGUISH THESE TRANSITIONS, EVEN UNFAVORABLE SCAN CONDITIONS. THE ASSEMBLY INCLUDES MEANS THAT GENERATE NARROW TEMPORAL WINDOWS TO IDENTIFY DETERMINED VALID MARK TRANSITIONS IN ORDER TO PREVENT TRIGGERING FROM BOX TRANSITIONS, BRIEF NOISE PULSES, ETC. DURING EACH FRAME INTERVAL, EACH MARK 14 IS SCAN FOLLOWING A CERTAIN NUMBER OF LINES, BUT ONLY THE SCAN OF THE CENTER LINE IS USED TO GENERATE A SAMPLE EXIT SIGNAL IN ORDER TO LOCK THE POSITIONS OF THE BINDERS IN A MEMORY FOR THEIR LATER COMPARISON WITH THE DIASCOPIC SIGHT TO DETERMINE THE COARSE SCANNING ERRORS. /P
