Abstract
This invention relates to a scanning densitometer for obtaining information on the areal distribution of optical density of photographic image by scanning the entire area of an image, comprising plural input optical fiber bundles of which faces are arranged across the image and of which light-emitting faces are arranged on a circle with a predetermined interval. Plural output optical fiber bundles have light-receiving faces arranged so as to respectively face the light-emitting faces and which output faces are arranged so as to respectively face plural photoelectric converting elements. A rotary disc between the light-emitting faces and light-receiving faces is provided with blue, green and red filters arranged on the circle, whereby information of the distribution of photographic density over the entire image area being obtained by measuring the light which passes through said filters of said rotary disc.
