摘要:
A silver halide photographic material containing a support having provided thereon blue-sensitive, green-sensitive, and red-sensitive layers, in which at least the blue-sensitive layer is composed of at least two layers including a more sensitive layer and a less sensitive layer. The most sensitive layer of the blue-sensitive layer is a blue-sensitive layer containing an emulsion of substantially monodispersed grains, and at least one layer other than the most sensitive layer contains an emulsion containing tabular silver halide grains of about 5:1 or more in average aspect ratio. The material has superior sharpness and graininess, and is useful for color photography.
摘要:
A read-out image is acquired by covering an image storage sheet, which contains a color image, with an image storage sheet pushing surface of a platen cover and reading out an image of a region on the image storage sheet pushing surface of the platen cover, the region on the image storage sheet pushing surface containing the image storage sheet. A region corresponding to the image storage sheet in the read-out image is then recognized. The image storage sheet pushing surface of the platen cover has a color other than colors which are ordinarily contained in image storage sheets. The region corresponding to the image storage sheet is recognized by judging that a pixel in the read-out image, which pixel represents a color different from the color of the image storage sheet pushing surface of the platen cover, is a pixel falling within the region corresponding to the image storage sheet.

In addition, the present photographic material enables enhancement of pressure resistance and processing efficiency.
