Image capture using display device as light source
First Claim
Patent Images
1. A method of capturing digital images, comprising:
- illuminating, by an electronic device, an environment during a pre-flash phase;
measuring ambient light of the environment during the pre-flash phase;
determining, by the electronic device, a flash intensity based on the measured ambient light;
determining, by the electronic device, a flash duration during the pre-flash phase;
illuminating a target in the environment for the flash duration with light at the flash intensity; and
capturing a digital image of the illuminated target.

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.).
