Abstract
A method for generating an image is provided. The method comprises capturing a first set of image pixels by an ultrasonic sensor comprising an array of ultrasonic transducers using a first beamforming pattern, wherein the first beamforming pattern comprises a first pattern of transmit signals routed to a plurality of ultrasonic transducers of the ultrasonic sensor. The method further comprises capturing a second set of image pixels at the ultrasonic sensor using a second beamforming pattern, wherein the second beamforming pattern comprises a second pattern of transmit signals routed to the plurality of ultrasonic transducers. The second beamforming pattern is different than the first beamforming pattern. The second set of image pixels corresponds to an edge region of the ultrasonic sensor. The method additionally comprises combining the first set of image pixels and the second set of image pixels to form the image. An electronic device and a method of generating an image of a fingerprint with a fingerprint sensor are also provided.
