When picking up the image of a target, the P-P noise levels are successively outputted from the P-P arithmetic part 13 synchronizing with data read (A/D conversion) from array-detecting elements. Then, the image which becomes the reference of a uniform level is read at plural points in a perpendicular direction (j) of arrayed reading elements and the element in which the difference between the maximum value MAXS(j) and the minimum value MINS(j) of the read data SD obtained for each pixel is extremely small, is discriminated as the defective element.
