Abstract:
    An image velocity computing device having a camera, a microcomputer, and a camera control is provided. The camera has a controllable exposure time, and is capable of capturing a plurality of images of objects. The microcomputer is coupled to the camera and is configured to determine an image flow of an object of at least one pixel occurring in images captured by the camera, to determine an exposure time to achieve a predetermined image flow, and to compute an image velocity based on the exposure time of the camera. The camera control is configured to receive exposure time information from the microcomputer and to control the exposure time of the camera.
