Abstract:
1. An image sensing apparatus comprising: an image sensing unit configured to sense an image sensing target which has a defective portion region; an image sensing condition change unit configured to change an image sensing condition while the image sensing unit senses the image sensing target; a calculation unit configured to calculate an evaluation value corresponding to the contrast between the defective portion region of the sensed image and a region other than the defective region of the sensed image; a first control unit configured to operate the image sensing unit and the calculation unit at a first time interval in parallel with operation of the image sensing condition change unit; a second control unit configured to operate the image sensing unit and the calculation unit within a range where the evaluation value obtained by the operation of the first control unit changes from increase to decrease at a second time interval smaller than the first time interval in parallel with operation of the image sensing condition change unit; and an image sensing condition setting unit configured to set the image sensing condition based on the evaluation value obtained by the operation of the second control unit.
