この発明は、マイクロフィルム等のフィルム画像の処理
方法、特にフィルムに付着した傷、ゴミ等に基づく散乱
光を除去してフィルム画像を正確に処理するための方法
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for processing film images such as microfilm, and more particularly to a method for accurately processing film images by removing scattered light caused by scratches, dust, etc. attached to the film.
フィルム（たとえばマイクロフィルム）の画像をコピー

シミリ等で電送することができる。The configuration of a device that copies images on film (for example, microfilm) or transmits them by facsimile is as shown in Figure 1, in which light from a light source 1 is converted into parallel light by a lens system 2. film 3 after
The transmitted light of the film 3 passes through the lens system 4 and is then irradiated onto a copying photosensitive drum (not shown), so that the image on the film 3 is copied onto the paper 5 via the photosensitive drum. ing. Further, a rotatable mirror 6 is disposed below the lens system 4, and by rotating the mirror 6 and placing the mirror 6 at an angle in the optical path as shown by the broken line in the figure, the reflection can be achieved. Light is irradiated onto the line sensor 7,
The image information on the film 3 can be optically scanned and read by the line sensor 7, and the image information can be converted into an electrical signal and transmitted by facsimile or the like.
ところで、このようなリーダプリンタではフィルム３の

されることになる。By the way, in such a reader printer, if there are no scratches, dust, etc. attached to the surface of the film 3, the lens system 2
The parallel light from the camera directly passes through the film 3 and is processed using density information corresponding to the image projected on the film 3.
しかしながら、フィルム３に第２図に示すように傷３１

することにある。However, as shown in FIG. 2, there are scratches 31 on the film 3.
is attached, the parallel light is scattered by this scratch 31 as, for example, Ll, L2, and these scattered lights Ll
, If L2 is processed as is, the image quality will deteriorate and the data will be recalled electronically. Therefore, an object of the present invention is to provide a method for processing images with high precision by removing scattered light caused by scratches, dust, etc. on the film 3 as described above.
以下にこの発明を説明する。This invention will be explained below.
この発明は、マイクロフィルム等のフィルムに平行光を

偏向板で偏向することにより、フィルムからの散乱光を
除去するようにしたものである。This invention applies parallel light to a film such as a microfilm, processes the transmitted light or reflected light of the film, and when the film image is read by a line sensor or projected onto a screen, etc., the transmitted light from the film is processed. Alternatively, the scattered light from the film is removed by polarizing the reflected light with a polarizing plate.

となる。FIG. 3 is a diagram showing an example of the method of this invention, in which the film 3 is irradiated with parallel light and the transmitted light LA from the film 3 is deflected by the deflection plate 10, thereby removing scratches 3 attached to the film 3. Scattered light L3 based on .33. Only L4 is blocked and removed by the deflection plate 10. In this case, the deflection plate 10 is deflected in the X direction shown in the figure, but for scattered light in a direction perpendicular to the plane of the paper, it is necessary to use another deflection plate that is deflected in a direction perpendicular to the deflection plate 10. Therefore, two polarizing plates different by 90 degrees are prepared based on the properties of the scattered light from the film 3, and the polarizing plates are used selectively, taking into account the direction in which the polarized light will be deflected. For example, it becomes possible to perform better removal of scattered light.

方向を紙面と直角方向に揃える必要がある。FIG. 4 shows another example of the present invention, in which the parallel light irradiated onto the frame 3 is deflected by a deflection plate 11, the deflected parallel light LB is irradiated onto the film 3, and the film 3 is irradiated with the parallel light LB. The transmitted light LA from 3 is deflected by a deflection plate 10 which deflects in the same direction as the deflection plate 11. As a result, the light LB before passing through the film 3 and the light LA after passing through the film 3 are deflected and aligned in the same direction, so scattered light from the film 3 can be more reliably removed, improving image quality in image processing. This can be further improved. In this case, the deflection plate 11 and lO
The directions of deflection must be the same; for example, when deflecting in a direction perpendicular to the plane of the paper, the directions of deflection of the deflection plates 10 and 11 must be aligned perpendicular to the plane of the paper.

In the example shown in the figure, parallel light may be deflected by a polarizing plate and irradiated onto the film, and the reflected light may be deflected in the same direction by another polarizing plate.

Also,
By irradiating the film with parallel light polarized by the polarizing plate, the scattered light is also polarized, so that the efficiency of removing the scattered light by the polarizing plate can be improved. Furthermore, even if the film is free of scratches, dust, etc., there is no problem with projection/reading from the film, so the deflection plate can always be inserted into the optical system of the film.
