Abstract (Basic): EP 546773 A
The user interface includes a signal input device (28) e.g. a mouse, and a colour space display window. A graphical representation of a colour space is drawn in the colour space display window. Colours are drawn in a current location in the colour space. The location has coordinates defined by the colour information signals representing each colour.
The colours drawn in the colour space can be modified by means of the pointing device. The pointing device can move the colour from one location to a destination location having coordinates defining a set of modified information signals.
USE/ADVANTAGE - Provides visually intuitive and directly manipulatable ways of organising, managing and predicting colour in context of uniform colour model.
Abstract (Equivalent): EP 546773 B
A graphical user interface (GUI) for modifying the appearance of a plurality of colours, said interface being for use in a system having memory means for storing colour information signals representing the plurality of colours, and means for displaying the plurality of colours; said graphical user interface including, means for receiving input signals from a user; a color space display window; color space drawing means for drawing a graphical representation of a color space in said color space display window and for drawing the plurality of colors in said color space, each color being drawn in a current location in said color space, said current location having coordinates defined by the color information signals representing each colour; and means for modifying one of the plurality of colours drawn in said color space in response to at least one signal received from said input signal receiving means, wherein said modifying means includes moving means for moving the one color from said current location to a destination location in said color space, said destination location having coordinates defining a set of modified color information signals corresponding to a modified color, said color space drawing means drawing said modified color in the destination location in said color space.
Abstract (Equivalent): US 5416890 A
A graphical user interface provides a graphical representation of a colour space in a colour space window on a user display and draws each colour in the palette in its current location in the colour space, thereby showing the relationship of each colour in the palette with other colours in the palette. The interface stores all colour representations as device independent colour specifications. The user interface stores a number of colorimetrically measured colours representing the gamut of one or more target hardcopy output devices, and displays the boundaries of a selected device gamut in the colour space. The user manually controls the appearance of a colour on an output printer device by moving a colour from a current location outside the target gamut to a destination location inside the gamut. The user may also edit the colour's lightness signal. A gamut clipping process ensures that the modified colour is producible in the target gamut. When the user moves a colour from inside a displayed target gamut to outside the gamut, a gamut constraining process prevents the colour from being moved beyond the boundaries of the gamut.
USE/ADVANTAGE - An user interface for interactively modifying, on a user display, the appearance of a palette of colours on one or more hardcopy output devices. The user may flexibly and conveniently display and edit the palette of colours in any of several colour spaces available, one of which is the uniform CIELAB colour space. Modifications to palette colours are stored for future use.
USH001506
A processor-controlled system for modifying a plurality of colours, each colour being represented by a set of colour information signals; said processor-controlled system comprising a display device for displaying the plurality of colours; an input device for receiving input signals from a system user; a processor connected for receiving said input signals from said input device and for providing the colour information signals representing each of the plurality of colours to said display device; and a memory device for storing data therein; the data stored in the memory device including the colour information signals representing the plurality of colours and data indicating instructions the processor executes; the processor being further connected for accessing the instruction data stored in the memory device; the processor executing the instructions indicated by the instruction data; the processor, in executing the instructions, presenting on said display device a graphical representation of a colour space; the graphical representation of said colour space including a graphical representation of each respective colour of the plurality of colours; the graphical representation of each colour being presented in a current location in said colour space having coordinates determined from the set of colour information signals representing each respective colour; the processor, further in executing the instructions, receiving said input signals from said input device indicating a movement action by the system user moving the graphical representation of one colour of the plurality of colours from said current location to a destination location in said colour space; the processor, further in executing the instructions, responding to said input signals indicating the movement action by determining from colour space coordinates of said destination location a set of modified colour information signals representing a modified colour; presenting on said display device a graphical representation of said modified colour in the destination location in said colour space; and storing the set of modified colour information signals representing the modified colour in the memory device.
