Vision system for detecting a picture and reproducing said picture as a picture within a picture |
摘要 |
A vision system comprising a pair of camera devices movably mounted contiguous to one another at substantially the same distance from the object field to be reproduced. A first of such camera devices has a relatively large viewing angle of the object field while the second camera device has a smaller viewing angle of the object field within the first viewing angle. The camera devices are connected through electronic circuitry to a picture reproduction device for reproducing a first picture in response to the first camera device and a second picture in response to the second camera device wherein the second picture replaces a variable portion of the first picture corresponding to the second smaller viewing angle. The camera devices are movable by conventional servo mechanisms and the location of the smaller picture within the larger picture is adjustable. The picture reproduction device may constitute a cathode-ray tube.
