I3A Tech Forum Looks in Depth at Camera Phone Image Quality Metrics, Dec. 7 at Stanford University.WHITE PLAINS, N.Y. -- The International Imaging Industry Association (I3A I3A International Imaging Industry Association I3A Installation Information Infrastructure Architecture I3A Iterative Image Interpolation Algorithm ), the leading global association for the imaging industry, has joined forces with Stanford University Stanford University, at Stanford, Calif.; coeducational; chartered 1885, opened 1891 as Leland Stanford Junior Univ. (still the legal name). The original campus was designed by Frederick Law Olmsted. David Starr Jordan was its first president. to present a Technical Forum on the topic of Camera Phone Image Quality, to be held Dec. 7, 2006 on the Stanford campus in California. The event is sponsored by Hewlett Packard. For more information and to register, go to www.i3a.org. In recent months I3A has taken the lead in standardizing image quality metrics metrics Managed care A popular term for standards by which the quality of a product, service, or outcome of a particular form of Pt management is evaluated. See TQM. for mobile phones by creating an industry-wide Initiative that will identify image quality metrics and associated test methods and develop a quality rating system based on both objective and subjective data. Presenters at the Tech Forum will offer their collective expertise, and will share what Initiative participants have learned so far about the issues surrounding camera phone image quality metrics and their likely solutions. "Image quality is an issue that affects every aspect of the camera phone ecosystem, yet until I3A's CPIQ Initiative was launched, it had not been addressed in a cross-industry manner," said Lisa Walker, I3A's president. "The Tech Forum is a unique opportunity to hear from the top minds in industry and academia on these complex issues, and, to make the most of the occasion, we've included networking breaks for attendees and presenters to meet and further discuss topics of mutual interest. I invite all interested parties to attend this important event." Need for Camera Phone Image Quality Metrics Lack of standards and metrics for measuring and testing camera phone image quality is one of the key issues affecting the imaging industry today. Camera phones currently on the market with identical sensor (megapixel One million pixels. Refers to the resolution of a digital imaging device (monitor, scanner, video camera, still camera, etc.). For example, a five-megapixel digital still camera might take a picture composed of 5,038,848 red-green-blue color dots (pixels). ) resolution capabilities produce images vastly different in quality. Carriers struggle with handset purchasing decisions due to the lack of available metrics for testing and comparing devices - sometimes all they can be sure of is whether or not a capture device is present. Handset makers struggle with the complexities inherent in component-based, size-constrained devices and in measuring consistent quality in mass production environments. At the same time, both groups realize that image quality is important to consumers, to motivate them to print or share those images (and thereby produce revenue for vendors). Participants in the CPIQ Initiative agree that the industry needs to create an effective, simple means of communicating image quality to its customers. To enable manufacturers and carriers to make comparisons among capture devices, handsets and components and to communicate a substantiated product quality rating to consumers, an Image Quality Standards, Testing and Rating System will be created. CPIQ plans to accomplish this goal by leveraging existing image standards, test methods and image evaluation techniques to develop a quality testing program and metrics, and will identify requirements for new image quality standards specific to camera phones. The Dec. 7 Technical Forum will address these topics and more. Camera Phone Image Quality Tech Forum Program The Forum will feature presentations by faculty members from the Stanford Center for Image Systems Engineering and by some of the leading technical minds in the industry. The preliminary agenda includes: * Opening Remarks Dr. Joyce Farrell, Stanford Center for Image Systems Engineering Lisa Walker, International Imaging Industry Association * Next Generation Camera Phones "Optical considerations in the design of camera phones" -- Dr. Peter Catrysse, Stanford University "Designing sensors with low-light sensitivity, high dynamic range and high speed image capture" - Professor Abbas El Gamal, Stanford University "Perceptual per·cep·tu·al adj.

Join I3A's Camera Phone Image Quality Initiative Following the Technical Forum, I3A's Camera Phone Image Quality Initiative group members will meet to continue the work begun in June 2006 by 45 representatives from key players in the mobile imaging industry, including carriers, handset, component and software manufacturers. The I3A Camera Phone Image Quality (CPIQ) initiative addresses the single most important issue in promoting the use and enjoyment of camera-enabled phones: image quality. The CPIQ Initiative is first identifying image quality metrics and associated test methods and will then develop a quality rating system based on both objective and subjective data. I3A invites new participants to join I3A and the CPIQ Initiative, which is now in its Investigative phase.
