Method of reproducing image

摘要

An image is reproduced on a light emission display system such as a CRT by use of an image signal obtained from the image. The image to be reproduced is an image which is taken by use of an irradiation field stop and the image signal is obtained from the image in such a manner that image signal components obtained from an area outside the irradiation field becomes lower in signal level than those obtained from the area inside the irradiation field. The image is reproduced as a visible image on the light emission display system according to gradation properties where the brightness level of a picture element becomes higher as the level of the image signal component for the picture element becomes lower. A picture element the signal level of the image signal component for which is not higher than a predetermined threshold value is displayed at a brightness within a predetermined lowest brightness level range.
