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 of capturing digital images, comprising:
evaluating, by a mobile device, a quality of an image of a target environment based on pixel intensity distribution of the image of the target environment, wherein the image has a moving portion and a nonmoving portion; determining a representation of a color distribution of the image of the target environment, wherein the representation represents one of a color distribution of only the nonmoving portion of the image and a color distribution of only the moving portion of the image; determining, by the mobile device, a flash color based on the representation; illuminating a target in the target environment with light emitted from a device configured to emit the light at the flash color; and capturing, by the mobile device, a digital image of the illuminated target.
