Inklayer image with transparency
First Claim
1. An inklayer image transparency system for use with an external system, wherein said external system includes at least one display device for displaying at least one image using a plurality of pixels, said inklayer image transparency system comprising:
- (a) a controller suitable for receiving signals and for providing image information to said display device;
(b) for each pixel of said plurality pixels, at least one of said signals being an address signal and at least one of said signals being a transparency control signal;
(c) memory functionally associated with said controller;
(d) said memory divided into at least two memory sections including a first memory section and a second memory section;
(e) said first memory section for storing foreground image information for display on said display device;
(f) said second memory section for storing background image information for display on said display device;
(g) said address signal for simultaneously fetching said foreground image information from said first memory section and said background image information from said second memory section; and
(h) said transparency control signal having a nontransparent state and a transparent state;
(i) said foreground image information being sent for display on said display device when said transparency control signal is in said nontransparent state; and
(ii) said background image information being sent for display on said display device when said transparency control signal is in said transparent state.

Abstract
An inklayer image transparency system of the present invention has a graphics controller or processor, memory, and a display device that may be external to the inklayer image transparency system. The graphics controller is suitable for receiving signals (e.g. an address signal and a transparency control signal) and for providing image information to the display device. The memory is divided into at least two memory sections including a first memory section for storing foreground image information and a second memory section for storing background image information. A single address signal received by the graphics controller is used for simultaneously fetching the foreground image information from the first memory section and the background image information from the second memory section. A transparency control signal having a nontransparent state and a transparent state is used to control whether the foreground image or background image is displayed. The foreground image information is sent for display on the display device when the transparency control signal is in the nontransparent state and the background image information is sent for display on the display device when the transparency control signal is in the transparent state.
