    Abstract: Provided are a system and method for image sharpening is provided that involves capturing an image, and then decomposing the image into a plurality of image-representation components, such as RGB components for example. Each image-representation component is transformed to obtain an unsharpened multi-resolution representation for each image-representation component. A multi-resolution representation includes a plurality of transformation level representations. Sharpness information is transported from an unsharpened transformation level representation of a first one of the image-representation components to a transformation level representation of an unsharpened multi-resolution representation of a second one of the image-representation components to create a sharpened multi-resolution representation of the second one of the image-representation components. The sharpened multi-resolution representation of the second one of the image-representation components is then transformed to obtain a sharpened image. The improved and sharpened image may then be displayed.

    Abstract: In one embodiment of the invention, an apparatus is disclosed including an image sensor, a color filter array, and an image processor. The image sensor has an active area with a matrix of camera pixels. The color filter array is in optical alignment over the matrix of the camera pixels. The color filter array assigns alternating single colors to each camera pixel. The image processor receives the camera pixels and includes a correlation detector to detect spatial correlation of color information between pairs of colors in the pixel data captured by the camera pixels. The correlation detector further controls demosaicing of the camera pixels into full color pixels with improved resolution. The apparatus may further include demosaicing logic to demosaic the camera pixels into the full color pixels with improved resolution in response to the spatial correlation of the color information between pairs of colors.

    Abstract: A calibration assembly may be used with an endoscopic imaging system having a field of view. The calibration assembly may comprise an interface configured for constraining engagement with the endoscopic imaging system and a target coupled with the interface so as to be within the field of view. The target may include a plurality of calibration features. The calibration assembly may be reconfigurable from a first spatial arrangement between the target and the endoscopic imaging system to a second spatial arrangement between the target and the endoscopic imaging system. The calibration assembly may also comprise a processor configured to obtain, from the endoscopic imaging system, first and second images of at least some of the calibration features of the target at the first and second spatial arrangements. The processor may also generate calibration data for the endoscopic imaging system using the first and second images.
