Abstract
One of the main subjects of tone reproduction is to produce the pictures optimized to display, transferred from real world's luminance via camera. In our study, we propose a new tone reproduction method for TV program production, especially for high-contrast outdoor live programs. Our method performs contrast improvement for specified luminance range without influence over another range. We verified our method by prototyping realtime system on graphics workstation, and also we measured the performance of HDTV video processing.
