摘要： In the present invention, to provide an image reading apparatus capable to read images of document images having different gloss levels with a reproducibility suitable for uses, a data processing means is provided to irradiate a document image with light from a regular reflection light source and a diffuse reflection light source, and to generate image data based on a regular reflection output value and a diffuse reflection output value obtained from a photoelectric converting means, this data processing means obtaining gloss pixel data by comparing, based on the regular reflection correction value for shading correction of a regular reflection output value, a diffuse correction output value for shading correction of the diffuse reflection output value, and a determining threshold for determining whether or not the regular reflection output value is a gloss pixel, the corrected output value corrected by the regular reflection correction value with the determining threshold, and obtaining a non-gloss pixel data from a corrected output value corrected by the diffuse correction value.
