| abstract | (57) [Summary] [Construction] The subtractor 45 subtracts the black reference data BST from the white reference data WST. The subtractor 46 subtracts the black reference data BST from the data ID obtained by A / D converting the output of the image sensor. The adder 47 adds the offset OFFSET to the output of the subtractor 45, and the adder 48 adds the offset OFFSET to the output of the subtractor 46. Then, in the division circuit 49, the correction data SOUT shown in the following equation is created from the outputs of the adder 48 and the adder 47. K is a constant. [Equation 1] [Effect] The dynamic range of the correction data is increased, and it is possible to express density in multiple gradations. |
