1. A unitary system for integrating image and speed determination data, the system, comprising: a common processor block; an image sensor coupled to said common processor block and operative therewith to capture images of a target; a laser subsystem coupled to said common processor block and operative therewith to determine a distance and speed of said target relative to said system and to determine that a higher resolution image of said target can be acquired by said image sensor; and a memory block coupled to said common processor block operative to store said images of said target, including said higher resolution image, received from said image sensor and data representative of said distance and speed of said target received from said laser subsystem, wherein said common processor block is operative to determine whether said target is probabilistically uniquely identifiable in said higher resolution image, and wherein said common processor block, said image sensor, said laser subsystem and said memory block are disposed within a handheld housing.
