Abstract

The ISO TC42/WG18-20-22-23 and ANSI/I3A IT10 Technical Committees have now been developing digital photography standards for over a decade. This work has led to the publication of standards on digital imaging terminology, digital camera ISO speed measurements, resolution measurements, OECF (linearity) measurements, image formats and metadata, and picture transfer protocol (PTP). More recently, standards on color encoding specifications and color architectures, a JPEG 2000 profile for digital cameras, camera noise and dynamic range measurements, digital camera specification reporting, and scanner resolution have been finalized. Work in progress includes image quality subjective testing methods, digital camera color characterization, and scanner dynamic range measurements. This paper will review past and current technical challenges, and the state of the solutions provided. In most cases, development includes a significant and innovative research component, which is discussed in relation to fundamental imaging issues. These standards are viewed from a broad digital photography perspective, and placed in context with other work in this area. In addition to providing a forum for the development of standards, technical committees are an important avenue for interaction between companies, user groups, and the government. Such avenues can have a great impact on emerging technologies.
