Abstract
Insufficient contrast can make it difficult to view an image or certain portions of the image. While existing software offers contrast enhancements to ease viewing, simultaneous enhancement of both contours and texture detail is difficult. This disclosure describes contrast-enhancement techniques controllable by a single parameter. The techniques enable a user to easily trade off texture detail against contour enhancement. A simple user interface such as a slider is provided that enables users to quickly adjust display results for different scenarios, such as reinforcing contours for textual material or emphasizing textures for fibered (e.g., paper, textile) material. Regardless of the value of the parameter, the designated area maintains high contrast. The techniques are usable in any image viewing/editing tool, including products designed for low-vision users.
