Abstract
A mobile device may include a display, a camera, one or more processors, and one or more memory devices storing instructions. The instructions may cause the mobile device to detect an optical pattern in a scene using the camera, to receive a user action, and to execute a focus cycle of the camera after receiving the user action. The focus cycle may change the focal position of the camera from a first focal position to a second focal position. The instructions may also cause the mobile device to acquire an image of the scene using the camera at the second focal position to decode the optical pattern, generating an object identifier.
