摘要： A method and apparatus for processing data representing an image in a first color space suitable for controlling a first image output device. The apparatus comprises a processor (11, 14, 17) for reversibly transforming the image into a perceptual color space defined by lightness, colorfulness and hue components, and for modifying the lightness, colorfulness and hue components of the image in accordance with a predetermined algorithm so that all colors in the image fall within the gamut of a second image output device; and a store for storing data defining the modified and unmodified lightness, colorfulness and hue components.

摘要： In a video retouching system having an image source (40), a refresh store (42) fed from the image source, and a monitor (46) supplied from the refresh store, an image modifier (44) is interposed between the refresh store and the monitor and is controlled by a modifying store having a multi-bit location for each picture element. The stored multi-bit values may be used, for example to modify the display to obtain a vignetting effect, or to lighten or darken picture elements or modify chrominance. Preferably a mask store (48) having one bit per pixel defines those pixels which may be modified and those which must not be modified. In one form, the store with a multi-bit location for each picture element controls the merging of two images.

摘要： Apparatus for performing a color transformation or color retouch operation on multibit digital data defining P color components of image pixels. The apparatus comprises a look-up table (2) which is addressed by N most significant bits (MSBS) of each color component value and which contains coarse versions of output pixel color component values. An interpolator (3) is responsive to M least significant bits (LSBS) of each color component value to interpolate fine versions of the output pixel values from the coarse output pixel values obtained from the look-up table. A processor loads coarse output pixel data for each color component into the 2.sub.NP addresses of the look-up table which may be addressed by the M MSBs of the input pixel data. The processor (8) is adapted to cause the value of N progressively to increase with successive iterations.

摘要： A method and apparatus for interactively modifying an image defined by original digital data, representing the color content of pixels of the image at a first resolution. The apparatus comprises a first store (4;12) for storing the digital data of the pixels at the first resolution; a monitor (9); a digitizing table (5); and an image processor (6;13,15). The image processor (6;13,15) is responsive to signals from the digitizing table (5) to select a modification algorithm and a portion of the image stored in the first store (4;12) to which the algorithm is to be applied. The image processor is further adapted to modify a subset of pixels of the image portion in accordance with the selected algorithm and to cause the modification image portion to be displayed on a monitor (9) at a second, lower resolution under the control of the modified pixels, and to modify and display successive subsets of the high resolution pixels while the same image portion and algorithm are selected and until all the high resolution pixels within the selected portion have been modified.

摘要： A method of displaying a selected section of an N-dimensional color space uses two memories (14,16). The first memory (14) stores memory addresses of the second (16). The second memory (16) stores data defining color at addresses corresponding to the selected section and background color at all other addresses. The defined colors and background are output to a display (11) so that the background areas blend with the existing background and only the color of the selected section is redrawn not the whole image.

摘要： Image display apparatus comprises a display monitor; an image frame buffer for storing data defining the color content of pixels of an image; and a control system for selecting from the frame buffer for each pixel displayed on the monitor the appropriate pixel data from the frame buffer. The relationship between the monitor pixels and the frame buffer pixels is defined by a preselected composite linear function, wherein the control system determines the frame buffer pixels corresponding to the monitor pixels by applying the preselected composite linear function in a stepwise manner.

摘要： Apparatus for interactively modifying an image represented by digital data defining the color content of pixels in the image in terms of color components defining a first color space comprises a store (1) for storing the original image; a look-up table (2) for transforming the image into a second color space (LCH) and a store (3) for storing the second color space representation. The second color space is defined by second color components having a reduced resolution relative to those of the first color space. The representation in the second color space is fed through a look-up table (4) whose contents can be controlled by an operator so that the image at low color resolution can be retouched interactively, the retouch version being displayed on a monitor (6). Once a satisfactory retouch has been achieved, the original image in the store (1) is modified and stored in the first color space in a store (13).In another application of the invention, a control data array such as a mask can be generated from the low color resolution image stored in the store (3).

摘要： Apparatus for generating a two-dimensional coloured display in which there is a variation of colour across the display in a predetermined manner, the colour of each pixel in the display being defined by one or more colour components. The apparatus comprises, for each colour component, a memory for storing a pair of gradation curves (X(i), Y(i)) representing the variation in intensity of the color component in orthogonal directions X, Y across the display; a monitor; and processing apparatus. The processing apparatus determines a resultant colour component value V(i,j) for a pixel to be displayed at a location (i,j) on the monitor in accordance with the following formula:V(i,j)=f[a(X(i))b(Y(j))+c(X(i))d(Y(j))]where the pixel has coordinates i,j and k is a normalizing constant, and where a, c, are functions of X(i), b, d are functions of Y(j) and f is an output function, the functions being chosen such that V(i,j) exhibits no discontinuities for all values of X(i), Y(j). The monitor is responsive to the resultant colour component values V(i,j) to display a corresponding colour at a position in the display corresponding to that pixel.

摘要： A method and apparatus for modifying an image defined by data representing the colour component content of each pixel of the image. The method comprises, for each colour component of each pixel, (a) generating unsharp (U) and sharp (S) data and performing an unsharp masking algorithm on the sharp and unsharp data to generate fringe data (F); (b) modifying the fringe data with a weighting function (.phi.) determined in accordance with the values of the sharp or unsharp data for all of the colour components of the pixel; and (c) combining the modified fringe data with the pixel data to generate modified pixel data. By applying a weighting function related to all the unsharp values for the pixel and hence to the input colour component content of the input signals of a particular sample area, the fringe amplitude is varied according to the colour of the region thereby enabling sharpening or smoothing to be appropriate to the part of the image e.g. sharpening hair and smoothing skin colours.
