Abstract
Apparatus and method for punching registration holes in exposed films having cooperating image areas, in which the films to be registered and punched are supported on a platform, punch means is mounted on the platform for punching registration holes in each film outside its image area, and electronic means is provided for producing an image, preferably, magnified, of at least one selected part of a film supported on the platform.
Claims30
Apparatus for registering exposed films having cooperating image areas, comprising in combination:
- (a) platform means for supporting said films to be registered,
- (b) punch means cooperating with said platform means and adapted to punch registration holes in a first one of said films disposed on said platform means at locations outside an image area of said first film, and
- (c) electronic means for producing an image of at least one selected part of said first film, said electronic means including:
- (1) at least one imaging means for producing video signals representing said image of said at least one selected part of said first film,
- (ii) means mounting said imaging means for movement with respect to said platform means for positioning said imaging means opposite said at least one selected part of said first film for viewing said part,
- (iii) at least one video display unit for displaying said image, and
- (iv) means connecting said imaging means to said visual display unit for transmitting said video signals to said visual display unit for display of said image.
Apparatus for registering exposed films having cooperating image areas comprising in combination:
- (a) platform means for supporting said films to be registered,
- (b) punch means cooperating with said platform means and adapted to punch registration holes in a first one of said films disposed on said platform means at locations outside an image area of said first film, and
- (c) electronic means for producing magnified images of at least two different selected parts of said first film, said electronic means including:
- (i) at least two imaging means for producing video signals representing said magnified images,
- (ii) means mounting each of said imaging means for independent movement with respect to said platform means for positioning said imaging means opposite said selected parts of said first film for viewing said parts,
- (iii) at least two video display units for displaying respective ones of said magnified images, and
- (iv) means connecting said at least two imaging means to said at least two visual display units for transmitting said video signals to said visual display units for display of said magnified images.
A method of registering exposed films having cooperating image areas, comprising the steps of:
- (a) disposing a first film on platform means having punch means for punching registration holes in film,
- (b) utilising said punch means to punch registration holes in said first film outside said image area thereof,
- (c) electronically producing video signals representing an image of at least one selected part of said first film,
- (d) disposing a second film on said platform means and electronically producing video signals representing an image of at least one part of said second film,
- (e) comparing said video signals derived from said first and second films,
- (f) adjusting said second film until said comparing step indicates that said at least one selected part of said first film is in register with a cooperating part of said second film, and
- (g) thereupon punching registration holes in said second film outside said image area thereof.
