Abstract

The present image generator visually suppresses a gap between two adjacent reflective surfaces of a reflective display. The image generator comprises memory and a processor. The memory stores position of the gap on the reflective display. The processor analyzes a stream of images to be displayed on the reflective display and determines corresponding lighting data alongside the gap. The processor further controls at least one lighting unit located behind a seam inserted in the gap based on the determined lighting data.

First claim

The invention claimed is:

1. A reflective display comprising:
two adjacent reflective surfaces being positioned side-by-side and spaced apart by a gap, the two adjacent reflective surfaces being adapted for displaying a stream of images thereon;
a seam inserted in the gap between the two adjacent reflective surfaces, the seam comprising a strip of light propagating material and at least one lighting unit located behind the strip of light propagating material; the seam further comprising a plurality of light detectors each located behind the strip of light propagating material, each one of the plurality of light detectors being configured for detecting an intensity and a color of light in an area of the two adjacent reflective surfaces adjacent to the strip of light propagating material, and for generating detected light data; and
an image generator for visually suppressing the gap between the two adjacent reflective surfaces, the image generator comprising a memory and a processor for analyzing the detected light data, determining corresponding lighting data alongside the gap, and controlling the at least one lighting unit based on the determined lighting data.

2. The reflective display of claim 1 , wherein the two adjacent reflective surfaces each comprise a plurality of pixels and the processor of the image generator is adapted for:
determining the corresponding lighting data by extracting a color and the intensity for a predetermined number of the plurality of pixels of the two adjacent reflective surfaces on each side of the seam for a section of the seam; and
averaging the extracted color and light intensity.

3. The reflective display of claim 2 , wherein the memory buffers a predetermined number of images to be displayed on the two adjacent reflective surfaces.

4. The reflective display of claim 3 , wherein the processor of the image generator is adapted for averaging the color and the intensity for a plurality of consecutive images.

5. The reflective display of claim 3 , wherein the processor of the image generator is adapted for averaging the extracted color and light the intensity for a plurality of nonconsecutive images.

6. The reflective display of claim 1 , wherein the at least lighting unit comprises a red light-emitting diode (LED), a green LED and a blue LED.

7. The reflective display of claim 1 , further comprising a wireless transmitter for controlling the at least one lighting unit.
