Title: The Innovative Contributions of Steven J. Friedman
Introduction
Steven J. Friedman is a notable inventor based in Bellevue, WA (US), recognized for his significant contributions to technology and design. With a total of 6 patents, he has made a remarkable impact in the field of color mapping and palette design.
Latest Patents
One of his latest patents is the "Luminance Sensitive Palette." This invention features a custom palette that comprises colors across various luminance levels, consisting of colors of uniform luminance. The spacing in luminance between levels varies, being closer at low luminance and increasing at higher luminance. The palette includes a gray color from each luminance level, highly saturated colors at the vertices of every alternate level, and a selection of lower saturation colors surrounding the gray color on each level. This selection emphasizes a higher concentration of flesh and sky colors.
Another significant patent is the "Method and Apparatus for Mapping Colors in an Image Through Dithering." This invention allows for the accurate approximation of a high color resolution image with a low resolution image through a unique combination of ordered dithering and error diffusion. The true color of each pixel is modified with error from previously rendered pixels and then dithered to an intermediate color of 15 bits. This intermediate color is mapped to the nearest displayable color using a precomputed look-up table, ensuring that any error between displayed and true colors is calculated and spread among neighboring pixels not yet rendered.
