ピング位置を決定することができるようになっている。Attribute data such as name, employee number, address, telephone number, etc. are input using input means such as the keyboard 3, the data is processed to create a barcode for each individual, and the printer 10 generates a barcode as shown in FIG. A photo pasting mount 21 with a barcode 22 printed thereon is created. An area 23 for attaching a photo is designated on the photo pasting mount 21. Incidentally, personal data files are stored on a magnetic tape 6, an optical disk 7, a floppy disk 8, etc. Next, Figure 2 (b

合成してカード基材にプリントアウトする。In this way, the layout information is also taken in by photographing the photo pasting mount, but of course the face photo information and the layout information may be input separately without using the photo pasting ledger. At the same time, counterfeit prevention information as shown in FIG. 3 is input. Examples of anti-counterfeiting information include putting a 30-color stamp in the background of a face photo (Fig. 3 (a)'), putting a wavy line 31 on the entire face photo (Fig. 3 (b)), and putting a Loco mark 32 on the face photo. (Fig. 3 (C)), provide a jagged part 33 like a stamp on the edge of the face photograph (Fig. 3 (d)), and create a frame-shaped image pattern in the boundary area between the face photograph and the card base material. 34 (Figure 3 (e)), or a tick mark 35 (Figure 3 (r)) on the facial photo information, or overlaying complex image patterns on the facial photo information, or adding anti-counterfeiting information at the border of the facial photo information. Add. It is difficult to imitate this type of photo processing with lines, wavy lines, logo marks, etc. using normal techniques, and it is also possible to fake the photo by making the edges of the photo jagged. If this were the case, the edges would have to be cut into jagged edges when replacing the photo, which is practically impossible. This kind of anti-counterfeiting information can be created, for example, by inputting a specific pattern by interacting with the display screen using the mouse 4, or by scanning a document containing stamps, logos, etc. with a CCD scanner or video camera. There are a method of photographing and inputting the image, a method of generating a specific pattern such as parallel lines, wavy lines, jagged edges, etc. by calculation within the image processing control device, and any method may be used. Furthermore, when simultaneously editing the attribute information, individual ID numbers and the like may be encrypted and output in a pattern on the facial photograph. In this way, when facial photo information, attribute information, layout information, and anti-counterfeiting information are input, the attribute information is read from the stored personal data file and compared with the barcode read together with the photo information. Attribute information and photograph information are matched, and counterfeit prevention information is combined with photograph information and printed out on a card base material.
偽造防止加工処理は第４図に示すようなステップで行う

と偽造防止情報の読み出しを行うと、画情報の各画素間
で演算を実行し、顔写真情報への偽造防止加工処理を行
う。情報間の演算は次式により行う。Facial photo information is color raster data, for example RSG.
%B Three colors, each color has 256 gradations as 8-bit data. Next, read out the counterfeit prevention information (
Step ■). In this step, the forgery prevention information created in advance is read onto the memory of the image processing control device. Anti-counterfeiting information is also available in 83 colors, R, G, and 8 in each color, just like face photo information.
Provide 256 gradations as bit data. When the facial photo information and anti-counterfeiting information are read out, calculations are performed between each pixel of the image information, and anti-counterfeiting processing is performed on the facial photo information. Calculations between information are performed using the following equation.
Ｘ （ｉ、 ｊ） ＝ ａ Ｘ Ａ （ｉ、 ｊ） ＋
ｂ Ｘ Ｂ （ｉ、 ｊ）ここにＸ （ｉ、 ｊ）は
偽造防止加工処理済画像のｉ行、」列の１画素の階調値
、Ａ（ｉ、ｊ） 、Ｂ（ｉ、ｊ）はそれぞれ顔写真情報
、偽造防止用情報のｉ行、ｊ列の１画素の階調値、ａＳ
ｂは偽造防止加工用係数である。偽造防止加工用係数ａ
、ｂの組合せの選択により、濃度のコントロールを行い

いは顔写真情報とイメージパターンの色を混ぜ合わせた
りする。X (i, j) = a X A (i, j) +
b X B (i, j) here, are the gradation value of one pixel in row i and column j of face photo information and counterfeit prevention information, respectively, and aS
b is a coefficient for anti-counterfeiting processing. Anti-counterfeiting coefficient a
, b are selected to control the density and make the image pattern white or black, or mix the facial photo information and the color of the image pattern.
例えば、顔写真情報全体に黒の波線を入れる場合にはａ
＝１、ｂ＝−１とし、波線部はＢ−２５５、非波線部は
Ｂ＝０のデータが格納されている偽造防止用情報と顔写
真情報との間で演算を行えばよい。For example, if you want to add a black wavy line to the entire facial photo information, a
=1, b=-1, and the computation can be performed between the counterfeit prevention information and the face photo information, in which data is stored as B-255 in the dashed line part and B=0 in the non-wavy line part.
そして、
ａＸＡ（ｉ、ｊ）＋ｂＸＢ（ｉ、ｊ）＜Ｏ−＋Ｘ（ｉ、
ｊ）＝ＯａＸＡ（ｉ、ｊ）＋ｂＸＢ（ｉ、ｊ） ＞２５
５−Ｘ（ｉ、ｊ）＝２５５とする。このとき波線部はＸ
（ｉ、 ｊ） ＝ ０、非波線部はＸ（ｉ、ｊ） ＝
ａｘＡ（ｉ、ｊ） 、すなわちもとの階調値となるので
、これを各包金画素に対して行えば顔写真情報の上に黒
の波線があられれることになる。なお、顔写真の背景の
みに黒線を入れたい場合には、デイスプレィをみながら
顔の輪郭を指定してくり抜き、輪郭内はｂ＝ｏとして同
様の処理を行えばよく、またカラー〇の波線４入れたい
場合は上記演算をＲＳＧ、Ｂごとに行えばよい。And aXA(i, j)+bXB(i, j)<O−+X(i,
j)=OaXA(i,j)+bXB(i,j)>25
5-X(i,j)=255. At this time, the wavy line part is
(i, j) = 0, non-wavy line part is X(i, j) =
axA(i,j), that is, the original gradation value, so if this is done for each envelope pixel, a black wavy line will be drawn above the face photo information. If you want to add a black line only to the background of the face photo, you can specify the outline of the face while looking at the display, cut it out, and perform the same process with b = o inside the outline, or add the wavy line of color ○. If you want to insert 4, you can perform the above calculation for each RSG and B.
また、ａ％ｂを位置の関数とすれば、場所により異なる
濃度の偽造防止パターンを付加することができる。次に
ステップ■で処理画像の外部記憶装置への記録を行う。Furthermore, if a%b is a function of position, it is possible to add anti-counterfeiting patterns with different densities depending on the location. Next, in step (2), the processed image is recorded in an external storage device.
この場合、情報量が多いので光ディスクなどの外部記憶
装置に書き込む。もちろん、処理済画像を特に保存する
必要が無い場合には、このデータを直接プリンタにより
出力するようにしてもよい。In this case, since the amount of information is large, it is written to an external storage device such as an optical disk. Of course, if there is no particular need to save the processed image, this data may be output directly to a printer.

完了する。FIG. 5 shows a printed card 40, in which a logo mark 32 is added to a facial photograph 41, and in the figure, a barcode 42 and a magnetic stripe 44 are further provided. Then, a cover film 45 is provided as a protective layer in the face photo area and the attribute information area 43, and the creation of the ID card is completed.
