An imager is provided. The imager has an imaging platen which presents an imaging surface against which an object to be imaged can be placed. The imaging platen has a photodetector layer and a light guiding layer operable to guide light towards the object. The imager includes a light source operable to emit light into the light guiding layer. The light source is located at an edge of the light guiding layer, to guide light into the light guiding layer of the imaging platen.

Imaging device

A method of displaying color data on an electronic paper display is displayed. The method comprises providing an electronic paper display having display pixels at a display pixel pitch and providing a color filter for said display. Said color filter comprises groups of colored filter elements, each said colored filter element having one of a plurality of different colors, wherein each group of colored filter elements defines a pattern of said colored filter elements. In said pattern a colored filter element overlies an integral number, n, of said display pixels, where n is two or more. The method also comprises providing color image data defining a plurality of color image planes, one for each of said different colors. Data in a said color image plane comprises image pixel data defining values for image pixels corresponding to said display pixels. The method also comprises selecting, from said data in each said color image plane, data for image pixels corresponding to display pixels over which the filter elements of the respective color for the color plane lie; and using said selected data to drive said electronic paper display; wherein on said display a rate of spatial variation of said selected data for said image pixels is less than said display pixel pitch.

Display systems and methods

The invention relates to an electronic device comprising a limited color display and a method of driving the display. The display has an array of pixels, a driver for driving each of said pixels in said array and a color filter which is aligned with said display whereby each of said pixels is sub-divided into a plurality of sub-pixels of different colors. The method comprises receiving a target image; generating a brightness image for said target image by determining a brightness value for each sub-pixel within said display; generating an output signal from said brightness image by determining an output value for each of said plurality of sub-pixels of different colors within the brightness image; and outputting said output signal to said driver to drive the display.
