Abstract
PURPOSE:To obtain correct picture element information by eliminating leak signals contained in respective output signals of plural reading picture elements provided in a line shape with the output signals of adjoining picture elements to respective picture elements. CONSTITUTION:When the output signal from a picture element 11 is fetched, since the leak signals from the adjoining picture elements 12 and 13 are added, it is necessary to remove these leak signals. Since the leak signals from the picture elements 12 and 13 to the picture element 11 are in proportion to the outputs of the picture elements 12 and 13 in a using output area, respective picture elements multiplied by proportional coefficients K1 and K2 in arithmetic circuits 14 and 15 go to leak signals. By subtracting the leak signals from the arithmetic circuits 14 and 15 from the output signal of the picture element 11 in a subtracting circuit 16, and fetching the leak signals as the complementary signals of the picture element 11, the influence of the adjoining picture elements 12 and 13 can be removed. The proportional coefficient can be obtained beforehand.
