Super high definition image digitizing system

A very-high-resolution image digitizing system that handles both still and motion images is presented. The system mainly consists of a high-resolution CCD line scanner and high-precision film transport equipment. Resolution characteristics are measured directly using test charts, and resolution of over 2048 pixels is obtained in both the vertical and horizontal direction. Therefore, this system can generate test sequences for super-high-definition images that have at least 2048*2048 pixels. Various corrections, such as shading-, gamma-, and color-correction and edge enhancement, are made, and good reproductions of original photo images are obtained. Sixteen standard images are digitized and prepared for coding simulations and other applications.<<ETX>>
