LIGHT RECEPTION DATA CORRECTOR

摘要

PROBLEM TO BE SOLVED: To provide a light reception data corrector which can effectively generate the correction data without using a reference medium to correct the light reception data including the unevenness of light quantity caused by the dispersion of light emission intensity of each of light emitting elements which form a light emitting part. SOLUTION: When a light receiving part 13 receives the direct light from a light emitting part 11, a correction data production part 17 calculates the product sum of data obtained by applying the weighting to each of light reception data received from the part 13 by a normal distribution function. Then the part 17 uses the obtained data as the correction data when it's supposed that a reference medium exists. A data correction part 19 corrects the reception data based on the correction data and an identification processing part 20 identifies based on the corrected light reception data.
