<title>Discovery of important factors to convey high-order sensation: image depth and related factors</title>

The coming information society will require images at the high end of the quality range. We are investigating the important physical factors for the difficult reproduction of high level, high quality sensation in the electronic capture and display of images. We have found a key assessment word 'image depth' that describes appropriately the high order subjective sensation that is indispensable for the display of extra high quality images. Related to the depth of images, we have discovered a new physical factor and the degree of precision required of already known physical factors for the display of extra high quality images. The cross modulation among R, G, and B signals is the newly discovered important physical factor affecting the quality of an electronic display. In addition, we have found that very strict control of distortion in both the gamma and the step response is necessary and that aliasing of the displayed images also destroys the images depth. This paper first outlines the overall objective of our work, and then describes the specific effect of cross modulation distortion, gamma, step response and aliasing that relate to image depth as important for extra high quality imaging.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
