Method for focussing a film scanner and film scanner for carrying out the method |
摘要 |
<p>A method for focussing a film scanner provides for selecting a plurality of partial regions of the picture to be scanned for the purpose of focus monitoring. During the focussing of one of the selected partial regions, the focussing of the other partial regions is simultaneously monitored. The monitoring is effected for example by simultaneous representation of the partial regions on a monitor screen, and/or by evaluation of the frequency and amplitude conditions of the partial regions. An optimum focal point is set if all the selected partial regions are simultaneously set sharply.</p> |
