    • 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.
    • 用于读取符号的成像阅读器中控制图像曝光的装置和方法采用用照明光照射符号的照明灯组件,用于从视场捕获来自符号的返回光的固态成像器 以及控制器,用于在第一曝光时间周期内连续地曝光成像器,以捕获来自该符号的第一区域的返回光并且最佳地成像,并且在第二曝光时间段内捕获来自该光源的返回光,并且 最佳图像,符号的第二个区域。 第一和第二区域具有不同的光强度水平。 第一和第二曝光时间段的持续时间是不同的。 控制器用于组合最佳成像的第一和第二区域以读取符号。
