Abstract: An apparatus and related methods for enhancing low dynamic range and high dynamic range digital images. The process converts single digital images into a form that can be shown on traditional electronic and computer displays and paper prints through luminance mapping and tone mapping functions. These functions require the calculation of values for each pixel within the digital image. The values calculated include, but are not limited to, color, grey-level, and luminance. The present apparatus and method builds upon the tone mapping process by combining log-average luminance values of various sized neighborhood tiles with the global log-average luminance of the entire image.

Abstract: A shower door having a lenticular image. The door member includes a first substrate layer on which a first interlaced image is printed. The door member also includes a lenticular lens layer registered with the interlaced image to have the effect of displaying a lenticular image. A frame preferably seals the edges of the door member to minimize intrusion of foreign matter including water. The door member may include an adhesive layer to attach the substrate to the lenticular lens layer or the substrate may be laminated to the lenticular lens layer.
