Abstract

This paper presents a very high resolution image digitizing system that handles both still and motion images, and the standard test images captured by the system. The system consists of a high resolution CCD line scanner and high precision film transport unit. Resolution characteristics are directly measured using test charts, and a resolution of over 2048 pixels is obtained in the vertical and horizontal direction. Various corrections, such as shading-, gamma-, color-correction, and edge enhancement are made, and good reproductions of the original photo images are obtained. Sixteen still standard images are digitized, and prepared for coding simulations and other applications. In the near future, motion standard test images will be digitized.
