ABSTRACT:
Provided is a picture reading device that is suited for discriminating the type/surface condition of a recording medium while requiring only a small circuit scale and less memory, and an image forming apparatus that uses the picture reading device. In a CMOS area sensor chip having a plurality of photoelectric conversion elements, there is provided a calculating unit for calculating the maximum value, the minimum value, and an average value of digital information related to a photoelectric conversion element in a specific area among the plurality of photoelectric conversion elements. Information calculated by the calculating unit is output in addition to digital information related to the plurality of photoelectric conversion elements.
