Reading apparatus and reading method

Provided is a reading apparatus that includes a light source that emits a light to a source material and an image pickup element that receives the light reflected by the source material, to thereby read the source material. The image pickup element is disposed so as to move to a plurality of positions at each of which the image pickup element is oriented at a different angle with respect to a surface to be read of the object to be read, and to perform reading at the plurality of positions. The reading apparatus compares read values obtained by the image pickup element at the plurality of positions to thereby decide a property of an image expressed on the object to be read.
