Abstract: A method for use with an electronic signboard (e.g., an LED signboard) compensates psychovisual chromaticity shift due to ambient light. The method first measures a color of light reflected from the signboard. Based on the measurement a set of calorimetric equations defining the desired light to be perceived as being displayed by each pixel of the signboard are solved. The calorimetric equations are the additive color mixture of the ambient light and the light to be actually displayed by the pixel in the absence of ambient light. The calorimetric equations may be expressed in units of uniform color space. The solutions of the colorimetric equations are then used to control the light actually displayed by the pixel.

Abstract: Techniques for de-noising a digital image using a multi-band noise filter and a unique combination of texture and chroma metrics are described. A novel texture metric may be used during multi-band filter operations on an image's luma channel to determine if a given pixel is associated with a textured/smooth region of the image. A novel chroma metric may be used during the same multi-band filter operation to determine if the same pixel is associated with a blue/not-blue region of the image. Pixels identified as being associated with a smooth blue region may be aggressively de-noised and conservatively sharpened. Pixels identified as being associated with a textured blue region may be conservatively de-noised and aggressively sharpened. By coupling texture and chroma constraints it has been shown possible to mitigate noise in an image's smooth blue regions without affecting the edges/texture in other blue objects.
