1. An imaging system for acquiring images of symbol targets and non-symbol targets located at variable distances from the system, comprising: a solid-state imager having an array of image sensors for capturing light from the targets over a field of view; a rangefinder for determining the distance to a target; and an image enhancer for enhancing the image of the target based on the distance determined by the rangefinder, wherein the image enhancer includes an enhancement filter calculated based on the distance determined by the rangefinder, wherein the enhancement filter is a filter operating on pixels of the image of the target captured by the array of image sensors.
