Abstract:
In the aforementioned image scanning apparatus of this embodiment, a condensation detection patch includes pluralities of patch areas with different reflectances arranged adjacently. A data acquiring unit acquires measurement values of the condensation detection patch by an image sensor as condensation detection patch data. A condensation determining unit determines whether condensation occurs or not on the basis of the condensation detection patch data corresponding to one with a low reflectance of two patch areas arranged adjacently in the patch areas.
