摘要：Two line sensors for reading an original are arranged parallel to each other andare moved in a subscanning direction to read an original image. The leading line sensorreads one line on the original, and an output from the leading line sensor is held inanalog memories. One line on the original is then read by the trailing line sensor, and anoutput from the trailing line sensor is added to the output, from the leading line sensor,held in the analog memories, thereby obtaining an effect equivalent to doubled chargestorage time in reading one line on the original. A desired resolution can be selected inaccordance with the sizes of two sensor elements, the layout of the sensors, and theoutput timings of the analog memories.
