Filed: 1989-08-01
Abstract: PURPOSE:To make sensitivity definite regardless of the change of an ambient temperature by keeping the temperature of a supporting member for silver halide photosensitive material in which infrared wavelength region is spectrally sensitized within a specified range. CONSTITUTION:Sensitive material for infrared S is conveyed to be subscanned by the rotation of a drum 9 in a state where it is wound to a part of the outer peripheral surface of the drum 9.

The projection image of the surface of the egg sheel as a time when the red LED is allowed to light is taken and the thickness of the egg shell is inspected from the brightness difference between the end part and central part of the egg.  The projection image is subjected to image processing to obtain the contour of a crack or stripe and the degree of parallelization of the contour line thereof is operated from the chain code of the countour line and a cracked egg and a striped egg are discriminated on the basis of the degree of parallelization. A blood egg is inspected on the basis of the brightness ratio of the projection images of the surface of the egg shell at both times when the red and yellow LEDs are allowed to light. Further, the inspection standard of the blood egg is altered corresponding to the brightness of the surface image of the egg shell photographed by allowing the luminaire 1 to light.
