Title: Roxanna F Rochat: Innovator in Color Control Technology
Introduction
Roxanna F Rochat is a prominent inventor based in Beaverton, OR (US). She has made significant contributions to the field of color control technology, holding a total of 3 patents. Her work focuses on enhancing the user experience in graphic image generation through innovative interface systems.
Latest Patents
Roxanna's latest patents include a "Computer display color control and selection system." This interface system allows users to select and control colors used in graphic images generated by a computer system. The system employs graphical representations of hue, chroma, and lightness combinations that can be rendered by a computer graphics system. A preferred embodiment of this invention includes a one-dimensional graph depicting the range of hues and a two-dimensional graph illustrating the range of chroma and value combinations available for a selected hue. The graphical representations are rendered in accordance with a Hue-Value-Chroma (HVC) color space, which has a high degree of perceptual uniformity.
Another notable patent is the "Display-based color system." This method and apparatus reversibly transform color selected from a gamut of colors producible by the primaries of a color display device into a perceptually uniform color space. The coordinates of this color space are readily convertible into internationally accepted standards for color measurement. Additionally, the invention provides a method for transforming the color space coordinates of a selected color into the corresponding relative primary intensity levels of the display device.
