摘要:
In an image reading apparatus using a solid state image pickup element, a smear amount and the total received light amount at whole image taking region of the CCD linear sensor when a light source is turned on without film, are measured and calculated.Using a ratio of the total received light amount when a light source is turned on without film to the one at the time of image reading, a smear correction data of each line is calculated for correction processing.
