Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ID information filing / printing apparatus capable of filing and printing various information for identification (hereinafter abbreviated as ID) including face photograph information. is there.

[0002]

2. Description of the Related Art The importance of facial photographs has long been recognized as one of ID information. Conventionally, a facial print information printed on photographic paper has been used as the facial photograph, such as a silver halide photograph or an instant photograph. However, when the face photograph information is printed on photographic paper, the information is limited to the printed photograph. For this reason, for example, you can file the face photo information in an invisible state,
It was extremely difficult to modify and duplicate. Therefore, the use range of information was limited to a narrow range. It should be noted that I printed the face photo information printed on
When used as D information, for example, I shown in FIG.
Like the D card 1, it is necessary to attach the photograph 1a to the ID card making mount 1b with an adhesive or the like for use. Therefore, the photograph 1a may be peeled off during use. In FIG. 1, 1c is a data printing / recording portion, 1d is an arrow indicating the insertion direction, and 1e is a magnetic stripe for magnetically recording data.

In order to eliminate the above-mentioned problems, a technique has been developed in which face photograph information can be handled as an electric signal and a printout can be made at a proper time when necessary. Note that image information generally has a larger amount of information than character / numerical value information, and thus there have conventionally been various restrictions when the face photograph information, which is one of the ID information, is handled as an electric signal. However, recently, due to the progress and development of image information devices, the restrictions are almost disappeared.

A technique that enables timely printout of facial photograph information consisting of electric signals is known as disclosed in, for example, Japanese Patent Laid-Open No. 63-316275. The above publication discloses an ID card producing device.

FIG. 9 is a block diagram showing the construction of the ID card producing apparatus cited from the above publication. This ID card producing apparatus converts an image pickup signal of a subject (person) S picked up by a color TV camera 2 into a digital multi-gradation signal by an A / D converter 3, and temporarily stores this in a frame memory 4. The signal processing circuit 5 including a look-up table memory, an adder, and the like performs signal processing on the temporarily stored image pickup signal (to remove color turbidity due to an incorrect spectral absorption element of a color material applied to a full-color video printer). Is calculated). In addition, this device electrically generates a graphics image or a character image by the operation unit 6 including a keyboard, and the generated graphics image or character image signal is a video including a look-up table memory and a video RAM. In the image forming unit 7, the image signal of the subject (person) S is combined and edited. Thus, the screen for the ID card is completed and is printed out by the full color video printer 8.

In order to manage the facial photograph information of the members who belong to various organizations such as companies and schools, a database system for filing the above facial photograph information is disclosed in the catalog of Fuji Photo Film Co., Ltd. "
Are known.

FIG. 10 is a block diagram showing the structure of a database system quoted from the above catalog. As shown in the figure, the above system captures signals from "video camera", "still video camera", "video presentation camera", etc. through an "image processor",
This is configured so that it can be displayed on a "monitor", written to a multi-data file, and printed out by a "video-graphic printer" as needed.

[0008]

The above-mentioned conventional technique is
Both capture face photo information as a full-color image,
This is used for filing and printing. Therefore, a video printer capable of full-color printing is required as the printer, and high-quality special paper is required as the print image paper.

In some cases, most of the ID information to be printed is character information and the facial photograph information is extremely small. In such a case, it is preferable that the character information is printed by an ordinary black-and-white printer that performs binary recording by turning on / off the print dots. In order to perform such printing, it is necessary to file the face photograph information as binarized image data.

The reason for this is that it is not possible in the usual case to print out the face photograph information etc. filed in one signal form by a printer configured to print in the other signal form. Is.

As described above, in the conventional system in which the face photograph information is stored in the database and used, the face photograph information is printed in an image signal form suitable for the printer in consideration of printing out the face photograph information at the appropriate time. It was necessary to file each. That is, when printing out using a multi-gradation video printer, filing is performed in the form of a multi-gradation image signal, and when printing out using a black and white binary serial dot printer or page printer. It was necessary to perform filing in the form of a binarized image signal binarized by pseudo multi-gradation conversion. This point has been a major limitation in using the faced photograph information and the like. Further, since it is necessary to always file the face photograph information in various image signal forms, it is necessary to use a large-capacity external storage device or the like, which has a drawback that the configuration is complicated and the size is increased.

It is an object of the present invention to print by a multi-tone video printer and a binary recording printer by using the same filing face photograph information, and filing in a database. It is possible to unify the data types that are used, simplify the data input / output operation, correction, and maintenance operation, and the storage device used for the database has a relatively small capacity compared to the conventional one. The object of the present invention is to provide a device for filing and printing of identification information, which has advantages such as a simple structure and a small size.

[0013]

In order to solve the above problems and achieve the object, the present invention takes the following means (1) to (5). (1) An image database memory that stores a plurality of pieces of face photo information for identification as multi-tone image data in which tone information is provided for each pixel, and the data extracted from this image database memory is density-wise for each pixel. Means for transmitting as print data for a multi-gradation video printer capable of modulation, means for obtaining pseudo multi-gradation binary data by performing pseudo multi-gradation conversion on the data fetched from the image database memory, and A binary recording printer that receives the pseudo multi-gradation binary data obtained by the means and prints the pseudo multi-gradation binary image is provided. (2) The following means is added to the means of (1) above.

The binary image printer is configured to print out the combined binary image data that is combined and edited on the binary image editing memory board. (3) The following means is added to the means of (1) above.

An image editing memory board is provided between the image database and the multi-gradation video printer, and it is necessary to form multi-gradation face photograph data and an identification card on the image editing memory board. The pattern and the character data are combined and edited, and the combined and edited composite multi-tone image data is printed out by a multi-tone video printer. (4) Video imaging means for imaging a subject to generate a plurality of multi-gradation video signals,

An image database for storing the above-mentioned multi-gradation video signals for a plurality of sheets created by the video image pickup means as multi-gradation image data having gradation information for each pixel,

A video printer that prints by density-modulating each pixel according to the output of the memory board, and multi-tone image data extracted from the image database is subjected to pseudo multi-tone conversion by calculation, and pseudo multi-tone data including face photograph information. A means for obtaining gradation binary data, a database for storing personal information as character / numerical data,

A binary image editing memory for synthesizing and editing the character / numerical data stored in this database and the pseudo multi-tone binary data containing the pseudo multi-tone converted face photograph information on one page. A board, and a binary recording printer that performs ON / OFF binary recording according to the output of the binary image editing memory board,

The identification card is printed based on the multi-tone image data of the image database, and the binary identification information including the binarized face photograph information is printed. To configure. (5) A video camera for transmitting an NTSC composite video signal, a signal conversion means for converting the NTSC composite video signal from the video camera into an RGB (red, green, blue) digital image signal, and this signal conversion A file device for storing a plurality of the RGB digital image signals converted by the means,

The above RGB read out from this file device

A board and a binary recording printer that performs ON / OFF binary recording according to the output of the binary image editing memory board are provided.

[0022]

As a result of taking the above-mentioned means (1) to (5), the following operation basically occurs.

Since the multi-gradation video printer and the binary recording printer have different recording systems, the signal form of print data that can be accepted is different. However, in this apparatus, the multi-tone image data read from the image database memory is converted into pseudo multi-tone binary data in real time by performing pseudo multi-tone conversion by the arithmetic means. Then, the converted pseudo multi-gradation binary data can be printed out by a binary recording printer. Of course, the multi-tone image data read from the image database memory can be printed out as a multi-tone image in which the density can be modulated for each pixel by a multi-tone video printer.

Thus, by using the image information filed in the image database memory in the signal form of the multi-tone image data, the multi-tone print by the multi-tone video printer and the pseudo multi-tone print by the binary recording printer are performed. It can be done optionally. As a result, it becomes possible to unify the data types to be filed in the database, and to simplify the data input / output operation, correction, and maintenance operation. Further, since the data type to be filed in the database can be unified, the capacity of the storage device used for the database can be relatively small, and the device can be downsized and simplified.

A still video camera may be used in place of this video camera, or a scanner or the like for capturing an image from a facial photograph printed in advance on photographic paper can be used. The image signal captured by the video camera 11 is converted into a signal suitable for filing by an image processing board (not shown) attached to the personal computer 10, for example, an RGB digital multi-tone image signal or a compressed image signal. It The converted signal is supplied to the database memory 13 as an image signal having multi-gradation image density information for each pixel. Then, it is stored as a large number of screens. Since the state of the image at this time is displayed on the monitor 12, it can be visually confirmed.

The database memory 13 is a memory having a predetermined capacity suitable for storing a large amount of gradation image data. A hard disk memory device, an optical disk memory device, an optical / magnetic disk memory device, a magnetic tape memory device, or the like can be applied as the database memory 13.

The multi-gradation video printer 14 is a video printer capable of density modulation for each pixel. As the multi-gradation video printer 14, a method of printing out on a silver salt photographic paper that has been put into practical use, a method of thermal sublimation transfer printing, a method of multi-gradation inkjet printing, a method of using thermosensitive coloring paper The thing etc. are applicable. The arithmetic circuit 15 for pseudo multi-gradation conversion is a circuit for performing pseudo multi-gradation conversion by operation to obtain pseudo multi-gradation binary data, the details of which will be described later.

The binary recording printer 16 is a printer that expresses a recording state by the presence or absence of recording dots. Examples of the binary recording printer 16 include a serial printer that prints on a line basis and a page printer that prints on a page basis. Wire dot printers, thermal printers, ink jet printers, and the like are known as the serial printers. Known page printers are electrophotographic printers such as laser printers and LED printers. FIG. 1B is a block diagram showing a specific configuration of a function added to the personal computer 10 and an arithmetic circuit 15 for pseudo multi-gradation conversion.

20, 21, 22, and 27 are data buses,
23 is a binarization circuit in the arithmetic circuit, 24 is a switching circuit, 25
Is a video printer interface (VP I / F),
26 is a serial printer interface (SP I /
F). Reference numeral 14 'indicates a video printer as a specific example of the multi-tone video printer 14, and 16' indicates a serial printer as a specific example of the binary recording printer 16. The binarization circuit 23 is composed of a binarization means by a dither method using a ROM or a binarization means by an error diffusion method.

The switching circuit 24 includes an input port A for directly fetching data from the internal data bus 20 of the personal computer 10 via the data bus 27, and the binarization circuit 2.
3 and an input port B for taking in binary data. Thus, the two input ports A and B are appropriately switched and the data that is selectively fetched can be output to the serial printer interface 26.

The video printer interface 25 is
Data bus 21 inside the personal computer 10
And a video printer 14 'for matching connection. Many of the video printers 14 'are usually S
Since a standard parallel interface such as CSI or GP-IB is provided, a dedicated control LSI is prepared. Therefore, the LSI may be used as the video printer interface 25.

Serial printer interface 26
Is a circuit for matching and connecting the data bus 22 and the serial printer 16 '. The serial printer interface 26 is normally composed of a standard I / F such as a Centronics I / F or an RS232C.

Thus, when the image data is printed by the video printer 14 ', the central processing unit (CPU) built in the personal computer 10 is first.
Command is sent from the video printer interface 25 to the control IC. Many of the commands are based on the general-purpose bus standards such as GP-IB and SCSI, and indicate that the data to be sent subsequently is the output data to the video printer 14 '.

Upon receiving the command, the video printer interface 25 receives the image data and the character data while performing bus control, and these are received by the video printer 14 '.
Output to.

When outputting to the serial printer 16 ', first, the switch 24 is switched to the input port A and set. Thus, a command indicating that the data to be continuously input to the serial printer 16 'is image data is
It is sent to the serial printer 16 'through the serial printer interface 26. The reason for sending the above command is that most serial printers 16 'are printers that are used to print characters in the normal case. Therefore, if only data is sent, this data may be recognized as a character code. Because there is.

The switch 24 is switched to the input port B after a command indicating that it is image data is sent to the serial printer 16 '. Thus, the image data from the database is inputted to the binarization circuit 23, binarized, and then sent to the serial printer 16 'through the switch 24 and the serial printer interface 26.

FIG. 2A is a block diagram showing a specific example of the binarization circuit 23. The latch circuit 30 is a circuit for latching data. IC circuit (integrated circuit) 3
Reference numeral 2 is a commercially available IC circuit for performing binarization by pseudo multi-gradation conversion by the error diffusion method. The line memory 31 is a memory necessary for performing the error diffusion method processing. The buffer circuit 33 is an output buffer circuit composed of a ROM and a RAM, and absorbs a time lag between the binary conversion operation of the binarization circuit 23 and the printing operation of the serial printer 16 '. belongs to. The buffer circuit 33 is also a conversion buffer circuit for performing the following conversions. That is, the output data of the IC circuit 32 is complete raster data, but the bit data requested by the serial printer 16 'is raster data having a width corresponding to the head of the printer. Therefore, the buffer circuit 33 performs conversion for giving the raster data a predetermined width.

The address generator 34 includes a buffer circuit 33.
It is for giving a read address to. R / W
The (Read / Write) controller 35 receives the data transmission request r from the serial printer 16 ′ and controls the address generator 34 and the IC circuit 32.
It also sends the clock signal CLK for the binary conversion operation to the IC circuit 32. The contents of the R / W controller 35 are so-called PLD (Programmable Lo).
It is programmed by an IC circuit such as a gic device or a gate array.

Next, the operation of the binarization circuit 23 shown in FIG. 2A will be described. When the R / W controller 35 detects that the data is latched in the latch circuit 30, the IC
The clock signal CLK is supplied to the circuit 32. Then,
The IC circuit 32 receives the data from the latch circuit 30,
A predetermined calculation is performed and the error is written in the line memory 31. At the same time, the latch circuit 30 informs the R / W controller 32 that the conversion operation is completed. R
When the / W controller 32 receives the signal,
The C circuit 32 is requested to write data in the buffer circuit 33. The RAM used for the buffer circuit 33 is a so-called dual-port RAM having both a serial port and a parallel port. Therefore, serial-parallel conversion is performed in the buffer circuit 33. Of course, an existing SP (serial-parallel) converter may be attached and used. In response to a data transmission request r from the serial printer 16 ', R
The address generator 34 is activated through the / W controller 35. By receiving the address signal from the address generator 34, the binarized image data stored in the buffer circuit 33 is supplied to the serial printer 16 'through the serial printer inch face 26.

Raster data for a page printer or the like is shown in FIG.
As shown in (b), the data scanned for each main scanning line is sent one after another. However, in a normal case, the print head 40 of the serial printer 16 'is shown in FIG.
As shown in, the plurality of head pins 41 to 44 are arranged in a direction perpendicular to the printing direction. Therefore, the data to be transmitted must be raster data D1 and D2 having a predetermined width as shown in FIG. Therefore, the capacity of the buffer circuit 33 shown in FIG. 2A is a capacity capable of holding raster data of a size (in many cases, the size equal to the number of pins of the print head) required by the serial printer 16 '. Required.

FIG. 3 shows another specific example of the binarization circuit 23, which is an example of using the dither method. The controller 50 is a controller that controls the line memory 51, the row counter 53, and the column counter 54, and is configured by a PLD or the like. The line memory 51 is a memory for one line. The internal memory of the personal computer 10 may be used instead of the line memory 51.

The pattern generator 52 is composed of a ROM or a RAM having a dither pattern built-in. Row counter 5
A counter 3 receives a signal from the controller 50 and generates a row address. The column counter 54 is a counter that also generates a column address.

Next, the operation of the binarization circuit 23 shown in FIG. 3 will be described. The CPU of the personal computer 10 first adjusts the data size. As is well known, the dither method is a method of expressing pseudo multi-gradation by the distribution of recording dot density. In the normal case, it is necessary to use a matrix in order to express gradation by turning on / off the recording dots. Since one gradation data is converted into many combinations of ON / OFF dots, the size of the image becomes large. For example, if the database has 100 × 100 dot n-bit gradation data, 100 × 100 × 2 ⁿ is required to accurately represent it. Dot data is needed. However, this makes the image size too large. Therefore, a method called the dither method is used to freely set the combination of the number of recording dots and the gradation expression. The adjusted data is written in the line memory 51. When this writing is completed, a writing end signal is input to the controller 50.

The controller 50 responds to the write end signal and the data transmission request r from the serial printer interface 26, and the read signal R of the line memory 51 and the control signal of the row counter 53,
Three signals, which are the control signal of the column counter 54, are generated. Thus, the data in the line memory 51 is input to the pattern generator 52, and the dither data is sent to the serial printer interface 26. (Second embodiment)

FIG. 4 is a block diagram showing the structure of the main part of the apparatus according to the second embodiment of the present invention, corresponding to FIG. 1 (b). The apparatus of the second embodiment is different from the apparatus of the first embodiment in that it has a personal database memory and a binary image editing memory 6

1 is provided together with the character image generator 62, and the obtained binary image data is transferred to the serial printer 16 'through the serial printer interface 26. Although not shown, the image position control is performed so that the characters and the face photograph information are stored as the ID information image inside the binary image editing memory 61. At this time, the serial printer interface 26 transfers the control code for image data to the serial printer 16 '. (Third embodiment)

The apparatus of the third embodiment is provided with a multi-tone image editing memory 71 capable of editing a multi-tone image so that the character data can be printed by the video printer 14 '. In this case, as the character image is expressed in black and white,
To convert binary data into black data values, white data values, or to convert binary data into data values of different densities for each color including halftone, so that colored characters are printed, The gradation conversion unit 72 is connected to the output end of the character image generator 62. Further, it is assumed that the pattern image data necessary for forming the ID card exists in the database memory 13 of FIG. As a result, the face image, the pattern image for the ID card, and the character image become one multi-tone image. This is the video printer 14 '
