Abstract
Abstract A display system is described for producing and showing colour images which includes a screen for displaying an interactive user interface. The display interface includes image colour choice areas, anti-alias colour choice areas, a current colour area, an echo icon area and user-movable cursor indications. The invention enables the display system user to choose among a plurality of displayed colours and to visually determine the effect of the choice. The method includes moving a cursor indication to a colour choice area, displaying the colour choice in the current colour selection area; and displaying in the echo icon area an echo icon drawn using the colour choice. This enables the display system user to see an enlarged view of the colour choice and an icon drawn with the colour and enables the user to assess the effect of the colour choice, both from the standpoint of the enlarged view and from the standpoint of exhibiting an expanded anti-aliased figure. In addition, the colour alteration also causes the image to be modified to reflect the colour change, thus enabling the user to obtain a complete assessment of the results of the colour selection.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
112 words
In a display system for producing and showing colour images, means for displaying an interactive user interface which includes image colour choice areas, anti-alias colour choice areas, a current colour selection area, an echo icon area and movable cursor indications, a method for enabling the display system user to choose from among a plurality of colours and to visually determine the affect of the choice, the method comprising; moving a cursor indication to a colour choice area; displaying the colour choice in the current colour selection area; and temporarily altering the display to reflect the effect of the new single colour selection, alone and in combination with the remaining colours previously selected.
Claim 2
Dependent Claim

In a display system for producing and showing colour images, means for displaying an interactive user interface which includes image colour choice areas, anti-alias colour choice areas, a current colour selection area, an echo icon area and movable cursor indications, a method for enabling the display system user to choose from among a plurality of colours and to visually determine the affect of the choice, the method comprising; moving a cursor indication to a colour choice area; displaying the colour choice in the current colour selection area; and temporarily altering the display to reflect the effect of the new single colour selection, alone and in combination with the remaining colours previously selected.
Claim 3
Dependent Claim
65 words
A method as claimed in claim 1, wherein the effect of the new colour selection alone is effected by displaying an echo icon in the echo icon area, the colour of the echo icon being the colour choice, whereby an enlarged view of the colour choice and an icon drawn with the colour choice are displayed to enable the user to assess the colour choice.
Claim 4
Dependent Claim
34 words
A method as claimed in claim 2, wherein the echo icon includes at least a portion comprising a curved line and selected proposed colour changes are exhibited to varying degrees relative to the curve.
Claim 5
Dependent Claim
46 words
A method as claimed in claim 3, wherein each anti-alias colour choice area includes an art colour which ramps to a target colour, the target colour being employed as a background for the echo icon when the cursor is positioned at an anti-alias colour choice area.
Claim 6
Dependent Claim
72 words
A method as claimed in claim 4, wherein each anti alias colour choice area includes a plurality of ramp colour bar areas, each bar area being a mixture of the art colour and the target colour, the ramp colour bar area closest to the art colour including a major amount of the art colour and the ramp colour bar closest to the target colour including a major amount of the target colour.
Claim 7
Dependent Claim
39 words
A method as claimed in Claim 5, wherein the interior portions of the curved anti-alias line are coloured with the art colour and increasingly peripheral areas of the curved line with colours exhibited by the ramp colour bar areas.
Claim 8
Dependent Claim
46 words
A method as claimed in any preceding claim 6 wherein the colour choice area is initially indicated by a created cursor provided with an outline which surrounds the colour choice area and a transparent interior, thus enabling the colour to be viewed in the cursor's interior.
Claim 9
Independent Claim
66 words
A method as claimed in any preceding claim, wherein the interface driver provides a mix colour command choice and, in response to selection thereof, a mix screen and a second cursor are displayed, the mix screen indicating hue, intensity and saturation variables, and, responding to user movements of the second cursor among the mix screen variables, accordingly alter the colour in the initial colour choice area.
Claim 10
Dependent Claim
88 words
A method as claimed in claim 8, wherein the anti-alias colour choice area includes an indicated art colour, target colour and a plurality of interposed colour bars indicating various mixtures of the target and art colours, the mix colour command acting to alter/replace the art/target colour, the display changing the art/target colour in the anti-alias colour choice area to the another colour choice, but not the target/art colour and revising the interposed colour bars by substituting the changed art/target colour therein in place of the initial art/target colour.
Claim 11
Independent Claim
47 words
A method as claimed in any preceding claim, wherein, if the cursor is moved from the initial colour choice area to another colour choice area, the second colour is displayed in the initial colour choice area and, if selected, becomes fixed in the initial colour choice area.
Claim 12
Dependent Claim
69 words
A method as claimed in claim 8, wherein, in response to a a mix colour command, a numeric colour code entry chart is invoked and displayed, together with a second cursor, the chart indicating entries for colour numbers, and hue intensity and saturation variables and, responsive to user movements of the second cursor and entries to the chart to accordingly alter the colour in the initial colour choice area.
Claim 13
Independent Claim
49 words
A method as claimed in any preceding claim, wherein the interactive user interface display is superposed over the displayed image being operated on, and every point in the displayed image which reflects the first colour is temporarily changes to the second colour in response to the tentative colour selection.
