A method of enhancing a full-color image of a scene includes capturing an image of the scene using a two-dimensional sensor array having both color and panchromatic pixels, forming an edge map in response to the panchromatic pixels, forming the full-color image in response to the captured color pixels, and using the edge map to enhance the full-color image.

Edge mapping incorporating panchromatic pixels

An image sensor is disclosed for capturing a color image, comprising a two-dimensional array of pixels having a plurality of minimal repeating unit wherein each repeating unit is composed of eight pixels having five panchromatic pixels and three pixels having different color responses.

Light sensitivity in image sensors

A method for producing a noise-reduced digital color image, includes providing an image having panchromatic pixels and color pixels corresponding to at least two color photoresponses; providing from the image a panchromatic image and at least one color image; and using the panchromatic image and the color image to produce the noise-reduced digital color image.

Noise reduction of panchromatic and color image

A method of enhancing a full-color image of a scene includes capturing an image of the scene using a two-dimensional sensor array having both color and panchromatic pixels, forming the full-color image in response to the captured color pixels, forming a reference panchromatic image in response to the captured panchromatic pixels, forming an edge map in response to the reference panchromatic image and using the edge map to enhance the full-color image.

Edge mapping using panchromatic pixels

A method for forming a final digital color image, includes: capturing an image using an image sensor having panchromatic pixels and color pixels corresponding to at least two color photoresponses; providing from the captured image a digital high resolution panchromatic image and a digital high resolution color differences image; and using the digital high resolution panchromatic image and the digital high resolution color differences image to produce the final digital high resolution full color image.

Interpolation of panchromatic and color pixels

A method of sharpening a full-color image of a scene includes capturing an image of the scene using a two-dimensional sensor array having both color and panchromatic pixels; forming the full-color image in response to the captured color pixels and forming a reference panchromatic image in response to the captured panchromatic pixels; forming a high-frequency panchromatic image from the reference panchromatic image; and providing a sharpened full-color image in response to the high-frequency panchromatic image and the full-color image.

Method of sharpening using panchromatic pixels

A method of processing an array of pixels captured by an image capture device, having a first two-dimensional array of pixels from the image capture device, some of which are color pixels, and some of which are panchromatic pixels; determining in response to ambient lighting conditions, whether panchromatic pixels are to be combined with color pixels; combining pixels to produce a second two-dimensional array of pixels which has fewer pixels than the first two-dimensional array of pixels; and correcting the color pixels.

Processing images having color and panchromatic pixels

A method of processing an array of pixels captured by an image capture device, includes providing a first two-dimensional array having first and second groups of pixels wherein pixels from the first group of pixels have narrower spectral photoresponses than pixels from the second group of pixels and wherein the first group of pixels has individual pixels that have spectral photoresponses that correspond to a set of at least two colors and the placement of the first and second groups of pixels define a pattern that has a minimal repeating unit arranged to permit the reproduction of a captured color image under different lighting conditions; responding to ambient lighting conditions, whether panchromatic pixels are to be combined with color pixels; combining pixels to produce a second two-dimensional array of pixels which has fewer pixels than the first two-dimensional array of pixels; and correcting the color pixels.
