An image sensor for capturing a color image comprising a two dimensional array of light-sensitive pixels including panchromatic pixels and color pixels having at least two different color responses, the pixels being arranged in a repeating pattern having a square minimal repeating unit having at least three rows and three columns, the color pixels being arranged along one of the diagonals of the minimal repeating unit, and all other pixels being panchromatic pixels.

For processing image data generated for a color filter array, classifiers are generated from the image data. A predetermined color component is determined by directional-interpolating the image data depending on the classifiers. Chrominance components are generated from linear-interpolated image data and the directional-interpolated predetermined color component. The chrominance components are directional-interpolated, and color components are extracted from the directional-interpolated chrominance components.

A method and system for improving picture quality of color images by combing the content of a plurality of frames of the same subject; comprising: at least one processor; the at least one processor comprising a memory for storing a plurality of frames of a subject; the at least one processor operating to combine the content of plurality of frames of the subject into a combined color image by performing: a process in which at least two multicolored frames are converted to monochromatic predetermined color frames; a gross shift process in which the gross shift translation of one monochromatic predetermined color frame is determined relative to a reference monochromatic predetermined color frame; a subpixel shift process utilizing a correlation method to determine the translational and / or rotational differences of one monochromatic predetermined color frame to the reference monochromatic predetermined color frame to estimate sub-pixel shifts and / or rotations between the frames; and an error reduction process to determine whether the resolution of the resulting combined color image is of sufficient resolution; the error reduction process comprising applying at least one spatial frequency domain constraint and at least one spatial domain constraint to the combined color image to produce at least one high-resolution full color image.

A method of manufacturing a color filter array plate is described. A substrate is first provided, and a black matrix is formed on the substrate to define several sub-pixel areas. A hydrophobic layer is then pasted on the black matrix, wherein the hydrophobic layer is made of materials including an ester compound having a chemical formula of: Then, an ink-jet printing process is performed where at least one type of color ink is injected into the sub-pixel areas between patterns of the black matrix. A thermal baking process is subsequently carried out to solidify the color ink for forming color film patterns.

An assembly useful for producing an encapsulated electrophoretic display is prepared from an electrophoretic medium comprising a plurality of discrete droplets (904) in a polymeric binder (906), each droplet comprising a plurality of charged particles dispersed in a fluid, and a front sub-assembly comprising a light-transmissive electrically-conductive layer (902) and a color filter array (920). The electrophoretic medium is laminated to the front-assembly (902, 920) at a temperature at which the polymeric binder (906) will flow and secure the electrophoretic medium to the front sub-assembly to form the final assembly, with the light-transmissive electrically-conductive layer (902) disposed between the color filter array (920) and the electrophoretic medium (904, 906).

According to a color imaging element and an imaging device of the present invention, because one or more pixels of first filters corresponding to transparence are disposed within a pixel line of each direction of a first direction to a fourth direction of a color filter array, it is possible to acquire brightness information in a high frequency range with high precision and reduce occurrence of a false color (color moire), thereby obtaining image data with excellent resolution. Further, because one or more pixels of the first filters corresponding to transparence are disposed within the pixel line of each direction of the first direction to the fourth direction, it is possible to realize color filters with excellent optical sensitivity.

A color filter array of an image sensor, the color filter array including a plurality of infrared ray (IR) filters, each of which filters out light to transmit wavelengths in an IR region; a plurality of first type color filters; a plurality of second type color filters; and a plurality of third type color filters, wherein some adjacent IR filters are arranged to form a T shape.

A method for correcting image data, in particular for colour correction and cross-talk reduction of image data obtained by an image sensor comprising image pixels (R, G, B) and non-image pixels (F), the image pixels (R,G,B) being overlaid with a colour filter array (CFA) and having a different spectral sensitivity than the non-image pixels, comprises determining a set of colour components (rold, gold, bold) for the image pixels (R,G,B) based on raw image data (rraw, graw, braw) read only from the image pixels (R,G,B) of the image sensor (10); correcting the set of colour components of non-direct neighbours of the non-image pixels (F) by means of a first colour correction matrix (CCM1); and correcting the set of colour components of direct neighbours of the non-image pixels by means of a second colour correction matrix (CCM2) different from the first colour correction matrix. An image sensor (10) and an auto-focus camera using same are also disclosed.
