Abstract

Currently most user interfaces to color editing programs only provide controls to modify the red, green and blue separations of the color image. It is proposed to provide an interface for real time color editing that provides more flexible control by allowing the user to modify not only the red, green, and blue separations of the image but also gives the user TV-like controls. For example, a black and white version of-the image can be shown and the contrast adjusted and then the color added. A Grinnell user interface (current state of the art) allows a user to modify values in the separate color separations, but there is no interaction between the red, green and blue values. Both Aurora and 12s displays allow these interactions by providing matrix arithmetic functions to modify the color tables, but no color editing interfaces have been previously designed for them. The proposed interface is presently implemented on an Aurora, using 10 bitdpixel and full color control of all 1024 possible input colors. In principle, this user interface allows typical photographic-like color balance, followed by TV-like color modification.

USER INTERFACE WITH COLOR EDITING PROGRAM (Cont'd)

Currently most user interfaces to color editing programs only provide controls to modify the red, green and blue separations of the color image. It is proposed to provide an interface for real time color editing that provides more flexible control by allowing the user to modify not only the red, green, and blue separations of the image but also gives the user TV-like controls. For example, a black and white version of-the image can be shown and the contrast adjusted and then the color added. A Grinnell user interface (current state of the art) allows a user to modify values in the separate color separations, but there is no interaction between the red, green and blue values. Both Aurora and 12s displays allow these interactions by providing matrix arithmetic functions to modify the color tables, but no color editing interfaces have been previously designed for them. The proposed interface is presently implemented on an Aurora, using 10 bitdpixel and full color control of all 1024 possible input colors. In principle, this user interface allows typical photographic-like color balance, followed by TV-like color modification.

The color user interface uses both sliders and buttons (see Figure 1). There are ten different sliders for editing a color image. For color balancing in Red, Green and Blue space, the sliders are red contrast, green contrast, blue contrast, more red/blue and a green tweaker. For color adjustment the sliders are luminance contrast, color contrast, hue, relative color, and overall lightness. The red, green, and blue contrast sliders chan...
