Full Description

Scope

The fundamental basis for making a measurement of resolution of a camera system is to reproduce a suitabletest chart with the equipment under test. This test chart shall include a pattern that has a suf cient amount of ne detail so that a quantitative observation can be made of the amount of this detail in the reproduced picture.This is usually done by incorporating in the chart a series of lines having graduated widths. The reproducedimage of this test chart is then observed on a picture tube or other suitable reproducing device. Thepoint in the picture where the lines are no longer visible as separately de ned images gives a measure of thesystem performance with respect to resolution. A quantitative method of measuring the horizontal resolution response of a camera system is based upon the oscilloscope display of the camera output voltage obtained from any single scan line across the vertical wedges of the resolution chart image. By choosing lines that occur at suitable times, the amplitude of the resulting signal can be plotted as a function of the line number of the chart.

Abstract

Revision Standard - Active.The methods for measuring the resolution of camera systems are described. The primary application is for users and manufacturers to quantify the limit where fine detail contained in the original image is no longer reproduced by the camera system. The techniques described may also be used for laboratory measurements and for proof-of-performance specifications for a camera.
