Abstract
A digital image capture system and method uses a display device to illuminate a target with light for improved image capture under poor lighting conditions. Various characteristics of the flash (e.g., brightness, color, duration, etc.) can be adjusted to improve image capture. Users are provided with feedback (e.g., live video feed, audio and/or visual countdowns, etc.) to assist them in preparing for image capture. The captured images are seamlessly integrated with existing applications (e.g., video conferencing, instant text messaging, etc.).
