This report describes a quantification method for luminance non-uniformity of a large LED backlight. In experiments described herein, participants subjectively evaluated artificial indistinct Mura images that simulated luminance non-uniformity of an LED backlight. We measured the luminance distribution of the Mura images. Then, the measured luminance(More)
We developed a quantitative evaluation method for luminance and color uniformity on a display screen. In this paper, we report the analysis result of a viewer perception of luminance and color uniformity. In experiments, observers subjectively evaluated Mura images which were showed on the light emitting diode (LED) backlight screen by adjusting the(More)
In this paper we describe AnyLight, a lighting device that uses computational light fields to offer highly programmable illumination for architectural environments. Relying on integral imaging--a technique commonly used to realize stereoscopic 3D displays--AnyLight can mimic the illumination effects of various light sources, both real and imagined. A(More)
We introduce AnyLight, a novel programmable lighting device that can mimic the illumination effects of a broad range of light sources ---both real and imagined---using the principle of integral imaging. The flat, panel-shaped device functions in essence as a type of light field display, relying on custom, 3D printed optics to precisely control light rays(More)
