ABSTRACT:
An image transfer system wherein latent images formed on a photosensitive medium by exposure to a radiation according to image signals are developed into visible images, the photosensitive medium having a basic minimum amount of exposure to the radiation, which substantially defines a lower limit of a density-variable range in which a density of the visible images is varied according to an amount of exposure of the medium to the radiation. The present image transfer system includes a first device, a second device and a developing device. The first device is adapted to expose the medium a predetermined basic amount not larger than the basic minimum amount. The second device exposes local areas of the medium to a controlled intensity of the radiation represented by the image signals, and thereby cooperates with the first device to form the latent images on the photosensitive medium. The latent images are developed into the visible images by the developing device. Also disclosed a filter device for compensating for a difference in sensitivity of the medium to different wavelengths of the radiation for color imaging.
