本発明はＸ線フィルム観察装置に関し、さらに詳しくは
、２枚のＸ線フィルム上の画像を容易かつ確実に観察対
比することのできるＸ線フィルム観察装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an X-ray film observation device, and more particularly, to an X-ray film observation device that can easily and reliably observe and compare images on two X-ray films. The present invention relates to a film observation device.
［従来の技術および発明が解決すべき課題］従来より、
材料や機器類の非破壊検査にはＸ線フィルムがよく用い
られている。[Prior art and problems to be solved by the invention] Conventionally,
X-ray film is often used for non-destructive testing of materials and equipment.
たとえば、第４図に示すような原子炉用の燃料棒におい

す。For example, in a fuel rod for a nuclear reactor as shown in FIG.
For example, non-destructive inspection using X-ray film is often performed to check for air bubbles, inclusion of foreign matter, abnormalities in the state of melt penetration, etc. In addition, in the same figure, 1
4 is a helical spring, and 15 is a fuel pellet such as UO.
この分野におけるＸ線フィルムの写真撮影では、２枚の
フィルムを順に写し、１枚のフィルム上で欠陥と思われ
る像が認められたときは、他の１枚のフィルムの同じ位
置に同じような欠陥像があるかどうか、確認する作業が
行なわれている。In X-ray film photography in this field, two films are photographed in sequence, and if an image that appears to be defective is observed on one film, a similar image is taken at the same position on the other film. Work is underway to confirm whether there are any defective images.
１枚のフィルムだけではこの確認作業は出来ない。This confirmation work cannot be done with just one piece of film.
と言うのは、フィルムの傷、感光乳剤のムラ。This is due to scratches on the film or unevenness in the emulsion.
現像処理上の不良操作、感光乳剤に対する物理的、化学
的作用その他種々の要因によって像形成が悪影響を受け
、像が本当の欠陥像であるか否かの判断がつかないから
である。This is because image formation is adversely affected by various factors such as poor processing during development, physical and chemical effects on the photosensitive emulsion, and it is difficult to determine whether the image is a true defective image or not.
ところで、前記確認作業は次のようにして行なわれてい
る。By the way, the above-mentioned confirmation work is performed as follows.
非破壊検査用のＸ線フィルムは箇所によフて黒化度の変
動幅がＯ〜３と大きい（普通の写真、たとえばスライド
ではＯ〜！程度）。X-ray films for non-destructive testing have a wide range of variation in the degree of blackening, ranging from 0 to 3 depending on the location (ordinary photographs, such as slides, have a range of 0 to 3).
黒化度： ｉ ｏｇ （Ｂｅ ／Ｂｌ ＞Ｂｏ：フィル

、黒化度の小さな部分は強い光か直接口に入るので目の
疲労が激しく、確認作業は容易ではない。Degree of blackening: i og (Be/Bl > Bo: Intensity of light before passing through the film Bl: Intensity of light after passing through the film Therefore, in order to be able to clearly observe areas with a large degree of blackening, we have The above-mentioned confirmation work is carried out using a Scherkasten (a projector for observing X-ray film), but since parts with a small degree of blackening are exposed to strong light or directly entering the mouth, the confirmation work is not easy because it causes severe eye fatigue. do not have.
また、Ｘ線フィルムの像は感光乳剤である銀粒子の粒状
性のため、すなわち俗に言う粒子の荒れのため、特に微
小欠陥の識別が難しいと言う問題点がある。In addition, images of X-ray films have a problem in that it is particularly difficult to identify minute defects due to the graininess of the silver grains in the photosensitive emulsion, that is, the so-called roughness of the grains.
本発明は上記事情を改善するためになされたものである
。The present invention has been made to improve the above situation.
本発明の目的は、Ｘ線フィルムによる非破壊検査等にお

観察対比することができるようにしたことを特徴とする
。[Means for Solving the Problems] The X-ray film observation apparatus of the present invention includes two imaging means for separately photographing two X-ray films, and a video signal outputted from each of the imaging means. It is equipped with an image processing means for processing, and a monitor for inputting the image processing signal outputted from the image processing means and displaying the X-ray film image on the screen. The feature is that it is possible to observe and compare the above.
以下１本発明の詳細な説明する。The present invention will be explained in detail below.
前記撮像手段としては一般にＴＶカメラが用いられる。A TV camera is generally used as the imaging means.
これはそれぞれ１枚のＸ線フィルムを撮像するため２台
用意される。Two of these units are prepared to each take an image of one piece of X-ray film.
ＴＶカメラとしては、固体撮像素子を用いたＣＣＤカメ
ラが解像度の点で最も好ましい。As the TV camera, a CCD camera using a solid-state image sensor is most preferable in terms of resolution.
前記画像処理手段は、これらの撮像手段からの映像信号
を画像処理するものである。The image processing means performs image processing on the video signals from these imaging means.
画像はそこで重ね合わせ、並列、拡大１合成等の所定の
処理がなされる。There, the images undergo predetermined processing such as overlapping, paralleling, and enlarged one-composition.
ここては、前記撮像手段からの映像信号を、先ず画像合
成装置に受け、この出力信号を通常の画像処理装置に入
力させることが好ましい。Here, it is preferable that the video signal from the imaging means is first received by an image synthesis device, and the output signal is inputted to a normal image processing device.
この画像処理装置では、輪郭の強調、スムージング、雑
音消去等を行なって画像をきれいにする。This image processing device makes the image clearer by enhancing contours, smoothing, eliminating noise, and the like.
上記画像処理手段からの出力信号はモニター（ＣＲＴ）
に入力させ、そこで画面上に表示する。The output signal from the above image processing means is a monitor (CRT)
and display it on the screen.
以上の構成によると、２枚のＸ線フィルムの像がモニタ
ーの画面上に強調されて映しだされるので、識別が難し
い微小欠陥でも容易かつ確実に識別することができる。According to the above configuration, since the images of the two X-ray films are displayed in an emphasized manner on the monitor screen, even minute defects that are difficult to identify can be easily and reliably identified.
また、この識別作業を複数の人間が同時に実施すること
が可能である。Furthermore, this identification work can be performed by multiple people at the same time.
なお１本発明では上記モニターに、画像のハードコピー
を出力するプリンターと映像信号をファイルするための
フロッピーレコーダーとを連結することが望ましい。In the present invention, it is desirable that the monitor be connected to a printer for outputting a hard copy of an image and a floppy recorder for filing a video signal.
このようにすると、モニター上の画像はプリンターによ
り八−ドコピーが取れるため、レポート等に活用し易く

ダーに画像を記録すれば、Ｘ線フィルムを保存する場合
（燃料棒の検査ではｌＯ年位は保存の必要あり）と違っ
て保存容量も重量も小さくなり、また検索も容易である
。In this way, the image on the monitor can be made into an eight-dimensional copy using a printer, making it easy to use for reports, etc., and easy to standardize.Furthermore, if the image is recorded on a floppy recorder, it can be saved on X-ray film. Unlike conventional fuel rods (which require storage for about 10 years for fuel rod inspection), the storage capacity and weight are smaller, and searching is also easier.
