Filed: 2002-01-10
Abstract: <P>PROBLEM TO BE SOLVED: To accurately measure harmful light which is generated by the aberration of a lens assembled in a camera and the like using an imaging element and called halo.  <P>SOLUTION: On a translucent screen with an almost uniform brightness, a plurality of transparent parts and a subject with a lower transparency than the transparent parts are arranged. The transparent parts are imaged so as to be exposed over the gradation range recorded with a camera to be measured. The image of the subject with lower transparency is imaged so as to be within the gradation range. From the relative brightness values of the transparent parts at imaging time which is estimated from the brightness value of the image of the subject with a lower transparency, the halo is obtained. A halo quantity is expressed with spread width against the brightness level relatively defined to the relative brightness value of the transparent parts in a brightness distribution in the transparent parts and the translucent plane around them.  <P>COPYRIGHT: (C)2003,JPO
