Pupil measuring system and Alzheimer's disease diagnosing system
Light sources (3A,3B) illuminate eyes (22A,22B) in a predetermined cycle using the pulse of light. Video cameras (1A,1B) are directed to the eyes, and a video signal of the pupil is output. This video signal is output to a digital computer (8) via video control units, a multiplexer (6), and an analo...

| Zusammenfassung: | Light sources (3A,3B) illuminate eyes (22A,22B) in a predetermined cycle using the pulse of light. Video cameras (1A,1B) are directed to the eyes, and a video signal of the pupil is output. This video signal is output to a digital computer (8) via video control units, a multiplexer (6), and an analog-to-digital converter (7). The digital computer detects the size of the pupil by processing an input video signal. |
