Continuous illumination of backlit display and of subject for image capture
Abstract:
A device to capture an image includes a camera oriented to capture a first image of a subject and a display oriented to display a second image that is viewable by the subject. A backlight is coupled to the display to provide light that passes through the display toward the subject. An image processor is coupled to the camera and the backlight to adjust an amount of light provided by the backlight responsive to a quality of the first image. The light provided by the backlight may illuminate the subject and thereby improve the quality of the first image. The image processor may further adjust the amount of light provided by the backlight responsive to an ambient light level sensed by an ambient light sensor. The image processor may further adjust the second image to adjust an amount of light that passes through the display.
