Abstract

A method, an apparatus, and a computer program product for managing a display device are provided. The apparatus may be a wearable device. The apparatus acquires data associated with a foreground corresponding to an image displayed on a display of the wearable device. The apparatus determines an image characteristic of the foreground based on the acquired data. The apparatus detects a change in the image displayed on the display. The apparatus adjusts, upon the detection of the change in the image, a display characteristic of the image based on the image characteristic of the foreground and the change in the image.
