Abstract
The disclosed technology relates to an electronic device configured to use the device's own display to provide an illumination source for front-facing image sensors and to a method of using the same. An electronic device for capturing a digital image using a front-facing image sensor and a digital display device includes a command input module configured to receive a command to capture the digital image, an illumination adjustment module configured to adjust the display device to an imaging illumination condition in response to the command, and a front-facing image sensor module configured capture the digital image using the front-facing image sensor under the predetermined illumination condition.
Claims33
A method for capturing one or more digital images of a scene using a mobile device including a front-facing image sensor and a touch screen, the method comprising:
- receiving a command to capture the one or more digital images of the scene;
- displaying, on the touch screen, an illumination image including an illumination region and a preview image of the scene;
- adjusting a color of the illumination region based, at least in part, on a comparison between an average chrominance value of the preview image and a target chrominance value to generate an adjusted illumination image;
- and
- capturing the one or more digital images of the scene using the front-facing image sensor while the scene is illuminated by the adjusted illumination image.
A non-transitory computer-readable medium configured to store instructions that, when executed by a processor of a mobile device including a front-facing image sensor and a touch screen, causes the mobile device to perform operations comprising:
- receiving a command to capture the one or more digital images of the scene;
- displaying, on the touch screen, an illumination image including an illumination region and a preview image of the scene;
- adjusting a color of the illumination region based, at least in part, on a comparison between an average chrominance value of the preview image and a target chrominance value to generate an adjusted illumination image;
- and
- capturing the one or more digital images of the scene using the front-facing image sensor while the scene is illuminated by the adjusted illumination image.
A mobile device for capturing one or more digital images of a user, the mobile device comprising:
- a front-facing image sensor;
- a touch screen;
- a processor;
- and
- a memory configured to store instructions that, when executed by the processor, causes the mobile device to:
- receive a command to capture the one or more digital images of the scene;
- display, on the touch screen, an illumination image including an illumination region and a preview image of the scene;
- adjust a color of the illumination region based, at least in part, on a comparison between an average chrominance value of the preview image and a target chrominance value to generate an adjusted illumination image;
- and
- capture the one or more digital images of the scene using the front-facing image sensor while the scene is illuminated by the adjusted illumination image.
