<p>A vision system comprises a picture capture device (1) with at least two camera means (5, 8) each having an optical means (6, 9) and an electro-optical detection means (7, 10), and a picture reproduction device with at least one display field (15) in which pictures from the camera means can be displayed simultaneously. The vision system is characterized particularly in that a first camera means (5) is arranged to register a first picture with a relatively large first viewing angle of an object field (4) whereas a second camera means (8) is arranged to register a second picture with a smaller second viewing angle (11) within said first viewing angle of said object field (4), whereby the picture reproduction device (2) is arranged to reproduce the first picture, the second picture replacing, to an optional degree, that part of the first picture which corresponds to said second viewing angle, whereby the first and second viewing angles have the same relative direction to the object field as in the pictures reproduced by the picture reproduction device (2), whereby the relationship object field extension/picture reproduction extension is the same for the first and the second pictures.</p> |
