Standard Testing Protocols for High Speed Digital Imagers
Abstract
This document defines specific optical and electronic tests that can be performed to evaluate high-speed digital imagers, guidelines on how to perform the tests, and samples of actual test results. Although there are several good software applications available that incorporate ISO Test standards, the OSG Working Committee agrees that the Imatest software should be accepted by the RCC working groups as the testing standard. Imatest is a suite of programs for measuring the sharpness and image quality of lenses, digital cameras, digitized film images, and prints using inexpensive, widely available targets. High-speed digital imaging systems are becoming the dominant means of photographic data recording in private industry and on U.S. government test facilities. Current state-of-the-art, high resolution sensors are producing high quality images that rival, and in some cases, surpass film imagery. Media distribution to customers occurs now in a matter of hours compared to sometimes days for film-based systems. Conventional computer hard drives and displays are the only things needed to view test images. Desktop photogrammetric data reduction algorithms are available that eliminate painstaking procedures to extract image metrics. All of these improvements have had an impact on camera manufacturers to produce better imaging products for use on the test ranges. One of the primary challenges for users of high-speed imaging systems is to determine which system will best suit his needs. Camera performance specifications issued by manufacturers can be confusing and may not be based upon common performance standards. This task's scope is to identify and recommend available electro-optical tests and procedures that comply with standards published by the International Organization for Standardization; these tests and procedures can be used to quantify camera performance and to make equitable comparisons from different manufacturers.
