Image Capture Using Display Device As Light Source

摘要

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.).

主权项

1. A method to capture digital images, comprising:
measuring ambient light in a first direction with a mobile device having a first camera aligned in the first direction and a display substantially orthogonal to the first direction; determining a flash color based on the measured ambient light with the mobile device; determining a flash intensity based on the measured ambient light with the mobile device; emitting light with the mobile device's display at the flash color and the flash intensity; and capturing an image with the mobile device's first camera coincident with the emitted light.
