ABSTRACT:
This is a film image input system wherein an image of the developed still photo film is made to focus on an image sensing plane of a charge coupled device through a taking lens to be converted into electric signals and the electric signals are input in a video monitor. The film image input system comprises: a zoom driving part for changing the image magnification of the taking lens; a scan mechanism for moving an image taking position on the film by the taking lens; and a control part for controlling the scan mechanism in such a manner that the moving speed of the scan mechanism is decreased with the increase in the image magnification of the taking lens and making the moving speed of a screen on the video monitor constant during scan. Furthermore, the control part can restrict the scan scope of the scan mechanism in accordance with the image magnification, satisfactorily display the scope being picked up at present on a display device, and return the scan position to the center of the film and return the image magnification to a predetermined standard magnification so that the film image in the whole frame can occupy the whole screen of the video monitor, upon receiving the standard reproduction command.
