A multi-dimensional controller () controls the multiple parameters of a lighting system (). A track-ball () that provides three axes of rotation (-), for example, is used to control each of three lighting parameters, such as chrominance, luminance, and saturation. In like manner, intensity, direction, and diffusion control may be controlled by a device with three degrees of freedom/control. Force-feedback () is optionally provided to indicate divergence from established presets () or recommended operating conditions. Switches () and other control elements are also provided to store or recall preset parameters (), override scheduled lighting settings, and so on.

In like manner, intensity, direction, and diffusion control may be controlled by a device with three degrees of freedom/control. Force-feedback () is optionally provided to indicate divergence from established presets () or recommended operating conditions. Switches () and other control elements are also provided to store or recall pre-set parameters (), override scheduled lighting settings, and so on.

Extracting and processing video content encoded in a rendered color space to be emulated by an ambient light source, using perceptual rules for intelligent dominant color selection. Steps include quantizing the video color space; performing dominant color extraction by using a mode, median, mean, or weighted average of pixel chromaticities; applying perceptual rules to further derive dominant chromaticities via [1] chromaticity transforms; [2] a weighted average using a pixel weighting function influenced by scene content; and [3] extended dominant color extraction where pixel weighting is reduced for majority pixels; and [4] transforming the dominant color chosen to the ambient light color space using tristimulus matrices. A color of interest can be further analyzed to produce a true dominant color, and past video frames can guide selection of dominant colors in future frames.

Dominant color extraction using perceptual rules to produce ambient light derived from video content

Flicker free operation of ambient light sources that emulate video content during low luminance conditions, where the ambient light source is output thresholded so that an on/off change of state of the ambient light source can be initiated after an intensity variable passes one or two thresholds. Output thresholding is used when extracting and processing video content encoded in a rendered color space, which can be decoded into frames tapped by an interframe interpolation process using only color information from selected frames, such as extracting average or other color information from an selected screen regions. Negative gamma correction helps prevent garish or inappropriate chromaticities and lumina.

A light condition recorder system and method including a light condition recorder () responsive to a lighting environment () and generating an environment signal (), a light simulator () responsive to the environment signal () and generating a lamp control signal (), and a lamp system () responsive to the lamp control signal () and generating a simulated lighting environment ().

Light condition recorder system and method

A home control system for automatic detection and warning of abnormal behavior includes a unit for observing behavior in a predetermined area under surveillance, a unit for processing an output of observed behavior from the unit for observing, and a pattern recognition module for recognizing whether the observed behavior is associated with predefined normal behaviors. The detection of predetermined normal behavior in progress leads to a provision of an anticipatory action. Upon recognition that the observed behavior is abnormal, an alarm signal is triggered to remind the user.
