Abstract
An input device uses banks of spatially separated light sources to selectively illuminate a field of view to acquire input image data used for biometric identification. In one implementation a plurality of banks of light sources are arranged from a first end to a second end of a device. Each bank may comprise light sources that are arranged on both sides of a device centerline. A camera with a rolling shutter acquires rows of image data beginning at the first end and scanning to the second end. While the camera is operating, banks of lights are progressively activated in coordination with the rolling shutter to illuminate a portion of a field of view and an object within, such as a hand, being imaged. This results in high-contrast input image data that is well illuminated, while reducing overall power requirements. The input image data may then be processed for identification.
