Abstract
Comparative data on the steadiness of motion picture film images are generally obtained by recording the qualitative observations of viewers. Recent problems encountered in evaluating the relative merits of several types of perforations, each of which was being considered as a universal 35-mm standard, necessitated the development of a method for obtaining specific quantitative steadiness data. An instrument which utilizes variable-area photoelectric recording techniques was devised to measure, indicate and record steadiness data of the motion picture image relative to the screen and/or perforation. Use of this instrument and a special test screen permits viewing of a projected motion picture test film while simultaneously measuring the image steadiness and recording the data measured.
