Abstract:
A method for super-resolution scanning in a image capturing device includes capturing a first color component of the image at one-half of a full resolution, capturing a first luminance component at one-half of the full resolution, and generating a first color-luminance output signal therefrom; capturing a second luminance component of the image at the full resolution and generating a luminance output signal therefrom; capturing a second color component of the image at one-half the full resolution, capturing a third luminance component of the image at one-half the full resolution, and generating a second color-luminance output signal therefrom; converting the first and second luminance components of the first and second color-luminance output signals and the third luminance component signal to a luminance component signal of 2X full resolution; and processing the full resolution output signals and the 2X full resolution output signal to form a combined output signal. A system for super-resolution scanning in a image capturing device includes a sensor array having a first row with first color pixel capturing elements which alternate with first luminance pixel capturing elements; a second row having second luminance pixel capturing elements; a third row with second color pixel capturing elements which alternate with third luminance pixel capturing elements; and a processing mechanism for transforming the first and second color components into full resolution color components and for transforming the luminance components into a 2X full resolution luminance component.
Abstract:
A printing system for rendering marks on a recording medium receives a multi-level grey scale pixel value representing a pixel having a first resolution. A screening circuit generates a screened multi-level grey scale pixel value equal to (G.sub.L -V.sub.i)+(S.sub.i -Th)*Dmp.sub.vi *Mod.sub.Eff wherein G.sub.L is the maximum grey level value of the pixel, V.sub.i is equal to the multi-level grey scale pixel value of the first resolution, S.sub.i is equal to a screen value corresponding to a position of the pixel, the image classification of the pixel and a brightness/darkness setting, The threshold value, Dmp.sub.vi is a video dependent dampening factor, and Mod.sub.Eff is a modulation multiplication factor. An interpolator converts the screened multi-level grey scale pixel value to a second resolution, the second resolution being higher than the first resolution, and a binarization circuit binarizes the converted multi-level grey scale pixel value so as to output a binary signal and an error value, the error value having a resolution equal to the first resolution. The error value is diffused to multi-level grey scale pixel values corresponding to pixels adjacent to the pixel having the first resolution, and the binary signal is converted into a mark on the recording medium.
Abstract:
A method for image processing includes determining edge pixels of a model image and determining features for the edge pixels of the model image. The image processing includes determining edge pixels of an input image and determining features for the edge pixels of the input image. The system matches the features of the model image with the features of the input image to determine candidate locations of an object within the input image.
Abstract:
A liquid crystal display includes a backlight that provides light and selectively modifies the transmission of light from the backlight to the front of the display. The backlight includes a plurality of spaced apart light waveguides and a plurality of selection elements associated with the light waveguides that change the characteristics of the material of the light waveguides to selectively direct the transmission of light toward the liquid crystal layer. The combination of the waveguides and the selection elements provide light to the front of the display in a non-uniform temporal manner and a non-uniform spatial manner during a frame.

A method of backlighting a liquid crystal display so as to improve the quality of the image displayed by the liquid crystal display. The method may vary the luminance of a light source illuminating a plurality of displayed pixels and vary the transmittance of a light valve of the display.
Abstract:
A system for influencing a state of a user includes a light source for emitting light influencing the state of the user. A light controller selectively controls the emission of the light including at least one of: (1) the spectrum of the light; (2) the duration of the light; (3) the distribution of the light; (4) the intensity of the light; and (5) the timing of the light. An analysis engine provides a signal to the light controller indicating a desired emission of the light, wherein the system selectively reflects a substantial portion of the emission of blue light from the light source of which a substantial portion is re-emitted as light different than blue light.
