PROBLEM TO BE SOLVED: To synthesize accurately video signals of each line sensor provided in a scanning direction. SOLUTION: This device is provided with plural line sensors 2a, 2b which are provided so that the scanning ranges are partly overlapped respectively and output video signals in the respective scanning ranges divided in an object in the scanning direction, an address assignment means that assigns an address corresponding to each position in the object 1 to the each video signal, plural function memories 18a, 18b that have a fixed value to address areas not overlapped with the other video signal for the every video signal outputted from the line sensors 2a, 2b and output a correction function that is sequentially decreased in the overlapped direction to the address areas overlapped with the other video signal, plural multipliers 17a, 17b that multiply each correction function outputted from the function memories 18a, 18b with each video signal outputted from the each line sensors 2a, 2b and an adder 19 that sums the output signals of the respective multipliers 17a, 17b and outputs the sum as a synthesized video signal by one line for the entire object. |
