Abstract:
An optical imager includes: an image sensor for capturing images of targets and outputting image signals; a lens for focusing the target on the image sensor as a function of lens position; a memory for storing predetermined lens positions determined from predetermined target sizes; and a controller for determining current target size based on captured images and positioning the lens at a predetermined lens position by correlating current target size with predetermined target sizes.
