摘要： The appearance of edges in an image is improved through precise placement of subpixels within pixel cells that are located on or near edges in an image. Image data is examined to identify a “target pixel” near the edge of an object that represents the object and is adjacent to a “background pixel” that represents only background. The target pixel may represent both the object and its background or it may represent the object only. A “second pixel”, adjacent to the target pixel and representing the object, is also identified. The second pixel may represent both the object and its background or it may represent the object only. The target pixel's location with respect to the second pixel is analyzed to determine the placement of a subpixel within the target pixel cell and the placement of a subpixel within the second pixel cell, such that the edge of the object is well-defined and the density of the object is preserved. A vertical smoothing process can additionally be performed to improve further the appearance of edges in the image. The technique is particularly advantageous for printing a halftoned object represented by pixels that are not saturated.

摘要： An algorithm that estimates or predicts a portion x1 of an original signal represented by the vector x=[x0 x1]T, of which x0 is the known portion and x1 the unknown portion, obtains the estimate y=[x0 {circumflex over (x)}1]T by first forming an initial estimate y0=[x0 0]T, that is, an initial estimate of x1, the unknown part of the original signal x. A de-noising matrix D1 is computed by applying a transform matrix to y0 and hard-thresholding coefficients using an initial threshold T0. An operation is performed using D1 to form a second signal estimate y1. The threshold may then be successively decremented by ΔT to obtain a next threshold Tn, after which a next de-noising Dn+1 is computed by applying the transform matrix to yn and hard-thresholding coefficients using Tn, and an operation is performed using Dn+1 to form the next signal estimate y(n+1). This loop in which the threshold is successively reduced to form the next signal estimate is performed until a final threshold Tf is reached.

摘要： A color distortion correction is obtained by calculating a color shift of a first color channel with respect to a second color channel along each pixel column of a scanned calibration image. The color shift defines a correction for the color distortions and the correction is then applied to subsequent scanned images. A system for correcting color distortions and an image processing chip configured to determine the color shift are also described.
