PURPOSE:To obtain a device for filtering optical spatial frequency by which optimum filtering is automatically executed in accordance with the kind of an image and a photographing condition. CONSTITUTION:Film 20 on which the image is photographed is provided with a magnetic recording medium, so that the kind of the image and the photographing condition are magnetically recorded. Light emitted from a light source 30 passes through a 1st lens 32, a slit 34, and a 2nd lens 36 and illuminates the image on the film 20. The light transmitted through the film 20 to transfer the image is condensed by a 3rd lens 38, and filtered by one filter 40 in accordance with the rotating position of a filter turret 52 A magnetic head 48 reads information magnetically recorded on the film 20 and gives it to a controller 50. Based on the information, the controller 50 controls to rotate the turret 52 so as to select the optimum filter 40. |
