Abstract

A crop, measure and scale system and a measure and scale system are provided for use in preparing an original image for processing. The crop, measure, and scale system includes first and second corner members which define an infinitely adjustable image frame. Each corner member includes a pair of diverging arms, one arm being characterized as an abscissa arm and the other as an ordinate arm, each of which includes an internally facing edge. A calculating measure is mounted on one of the corner members, such calculating measure including a slide rule with a ruler which extends between opposite edges of the cropped image, and a slide which provides for calculation of a reduction/enlargement percentage based on a predetermined desired dimensional change. The measure and scale system includes the calculating measure described above joined to an elongate member.

Dependent claims

A measure and scale system for use in preparing an original image for infinitely selectable resize processing to a reprocessed image, said system comprising

a first, elongate linear element including first and second, fixed, linearly-distributed, laterally spaced, elongate scale structures each containing original-image measurement indicia marks, and
a second, elongate linear element, mounted on said first element for reversible, longitudinal, relative sliding movement, and including first and second, fixed, linearly-distributed, laterally spaced, elongate scale structures each containing reprocessed-image calculation indicia marks, with one of these second-mentioned scale structures including reprocessed-image dimensional indicia marks, and the other such scale structure including reprocessed-image percentage-scale-resizing indicia marks, and with each indicia mark in said one scale structure having a nonexclusive, infinitely variable relationship with each indicia mark in said other scale structure, and vice versa.
