<p>The camera (10) has image sensor (12) for taking pictures. The focus position of receiving optics (18) is moved between first and second focus positions during which third and fourth focus positions to take one picture, determine degree of sharpness of images and image definition. The control and evaluation unit (22) is trained to acquire focus position cyclically and continuously between both focus positions back and forth to take another picture during the cyclical process, so as to reach largest image definition at focus position. An independent claim is included for method for recording sharp image.</p> |
