Abstract
A film checking apparatus which picks up images of two master films placed on two transparent film tables, displays the obtained images thereof on a color monitor thereby allowing for checking of the master films. The apparatus aids the film checking by providing a device for comparing the master films, detecting for the differences and finally displaying the differences in a blinking manner. The apparatus also provides two light sources and a means to switching between the two light sources depending on whether the object is of transmissive-type or reflective-type.
