ABSTRACT:
An arrangement for, and a method of, controlling image exposure in an imaging reader for reading symbols, employ an illuminating light assembly for illuminating a symbol with illumination light, a solid-state imager for capturing return light from the symbol over a field of view, and a controller for successively exposing the imager over a first exposure time period to capture the return light from, and to optimally image, a first area of the symbol, and over a second exposure time period to capture the return light from, and to optimally image, a second area of the symbol. The first and the second areas have different light intensity levels. The first and the second exposure time periods are different in duration. The controller is operative for combining the optimally imaged first and second areas to read the symbol.
