Ambient light-compensated reflective display devices and methods related thereto
First Claim
Patent Images
1. A method comprising:
- determining at least three color components of a first image;
detecting an ambient light color composition;
comparing the detected ambient light color composition with the at least three color components of the first image;
in response, weighting one or more of the at least three color components of the first image to provide a compensated image for display on the reflective display device, wherein the weighting compensates for a difference between the detected ambient light color composition and a specified color balance; and
enabling a secondary light source configured to provide light at least partially for use by the reflective display in displaying the compensated image.

Abstract
Various embodiments include devices, methods, data structures, and software that allow a reflective display device to, among other things, determine color components of a first image, detect an ambient light color composition, and weight one or more of the color components of the first image to provide a compensated image for display on the reflective display device. In one embodiment, the weighting compensates for a difference between the detected ambient light color composition and a specified color balance.

14. A reflective display device, comprising:
-
an ambient light processor configured to receive information about an ambient light color composition, the ambient light processor comprising a first comparator configured to determine a difference between the ambient light color composition and a specified color balance; a reflective display controller configured to receive information about a first image and to determine at least three color components of the first image, wherein the reflective display controller is coupled to the ambient light processor and configured to weight one or more of the at least three color components to provide a compensated image for display on a reflective display using information about the difference from the comparator; and a display light controller configured to control a secondary light source, the secondary light source configured to provide light at least partially for use by the reflective display in displaying the compensated image. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
