    • There is described a decodable indicia reading terminal which in one embodiment can capture and process a certain (e.g., a first) and a subsequent (e.g., a second) frame of image data, wherein the certain and the subsequent frames have different imaging attributes. In one embodiment the attributes between certain and subsequent frames are differentiated in that the certain frame represents light incident on pixels of a first image sensor and the subsequent frame of image data represents light incident on pixels of a second image sensor spaced apart from the first image sensor. Additionally, or in the alternative, the attributes between certain and subsequent frames can be differentiated in that the first frame represents light incident on an image sensor under a first illumination profile and the subsequent frame represents light incident on pixels of an image sensor under a second illumination profile. In one embodiment imaging attributes of a frame subject to decoding are maintained constant for each frame subject to processing during a time that a trigger signal remains active. In one embodiment the certain and subsequent frames can be processed to yield partial decoding results and the partial decoding results can be combined to form a complete decoding result.
    • 描述了可解码的标记读取终端,其在一个实施例中可以捕获和处理图像数据的某个(例如,第一)和后续(例如,第二)帧,其中特定和后续帧具有不同的成像属性。 在一个实施例中,区分特定帧和后续帧之间的属性,因为特定帧表示入射到第一图像传感器的像素上的光,并且后续帧的图像数据表示入射到与第一图像间隔开的第二图像传感器的像素上的光 传感器。 另外,或者替代地,可以区分某些帧和后续帧之间的属性,因为第一帧表示在第一照明轮廓下入射到图像传感器上的光,并且后续帧表示在第二个像素下的图像传感器的像素上入射的光 照明轮廓。 在一个实施例中,经过解码的帧的成像属性在触发信号保持活动的时间内被处理的每个帧保持恒定。 在一个实施例中,可以处理某些和后续帧以产生部分解码结果,并且可以组合部分解码结果以形成完整的解码结果。
