Is provided for storing the endoscopic image stored in the image storing memory and the patient data stored in the character information storing memory.

That is, when the video printer 8 prints the image information input to the video printer 8 in color on the printer paper 62, for example, the endoscopic image area can be designated from the keyboard 9 or the front panel 40. Thus, the endoscopic image area portion of the video signal can be stored in the designated (or selectively designated) storage area of the first memory of the image memory 59.

Further, by designating a patient data area portion from the keyboard 9 or the front panel 40, for example, the CPU 30 converts the character information of the patient data in that portion into R information.
It is transferred to the CPU 50 on the video printer 8 side via the S-232C signal line 19, and this CPU 50 designates corresponding character information from the character generator 53 in the second memory of the image memory 59 (or can be designated by selection). It can be stored in the storage area.

The first memory and the second memory each have a storage capacity for an image amount to be printed on one sheet of print paper 62, for example, and the information stored in each can be superimposed and output. Further, since the respective storage memories are separated, it is possible to easily store a plurality of images in the first memory, for example. Therefore, by issuing a print instruction from the front panel 40 or the like, the endoscopic image and the patient data, which are separately stored in the image memory 59, can be output as a print image.

Next, the operation of this embodiment will be described. The endoscope processor 6 to which the electronic scope 4 is connected drives the CCD 16 in the electronic scope 4 to obtain an endoscopic image, and at the same time, images the patient data input from the keyboard 9 and superimposes it on the endoscopic image. As shown in FIG. 3, for example, the endoscopic image display area 7B displays the endoscopic image in color on the monitor screen 7A, and mainly displays the patient data display area on the left side (and the upper and lower portions) thereof. Patient data is displayed in 7C.

The patient data includes an ID number, patient name, sex, age, date of birth, date of endoscopy (or stopwatch), hours, minutes, seconds, comments, and the like.

For example, when the VTR is selected, the recording display on the VTR, and when the SCV, SVR, DF (digital file) and VD (endoscopic file) are selected, their counters are displayed.

When the freeze switch of the scope switch 17 is operated, a freeze instruction signal is input to the image signal processing circuit 22 via the parallel I / O 34, and a still image is stored in the still image memory in the image signal processing circuit 22. It is stored and the still image is output. In this case, the moving image can be reduced and displayed in the reduced image display area 7D. Further, when an image capture instruction or printout instruction operation is performed from the scope switch 17 of the electronic scope 4 or the front panel 40 to the video printer 8, the instruction signal is sent to the video printer 8 side via the RS-232C control line 19. Transferred to.

Further, the patient data displayed on the monitor 7 by the input from the keyboard 9 is output as an image to the video printer 8 and also as data via the RS-232C control line 19. On the video printer 8 side, the image input from the video signal input terminal 44 is stored in the first memory of the image memory 59 via the interpolation circuit 48 and the memory controller 58 which performs interpolation processing when digitizing the image and printing the image by enlarging it. To be done.

At this time, by controlling the interpolation coefficient and the timing of writing the image in the image memory 59, as shown in FIG.
Alternatively, the endoscopic image can be reconstructed as shown in FIG.
In FIG. 4, two endoscopic images 65A are printed in the two-division mode using the enlargement function, and the patient data 65B is printed below the two endoscopic images 65A. Since the means for separating the endoscopic image and the patient data is formed, it becomes possible to enlarge and print only the endoscopic image portion as shown in FIG. Even if you can
Part of the image cannot be printed, and part of the image will be missing).

When printing in the 2-split mode,
If the patient data is the same, by storing only one patient data in the second memory of the image memory 59, it is possible to eliminate the waste of repeatedly printing the same data. Further, the patient data printing position is stored in a memory separated from the endoscopic image storage memory, so that it can be printed at any position according to the user's selection, for example, as shown in FIG. Endoscopic image 65 as shown
You can also print under A.

Further, FIG. 5 shows a print image printed in, for example, an 8-division mode without using the enlargement function, and shows eight endoscopic images 66A and patient data 66B below them.
Is printed. These selections may be controlled by the endoscope processor 6 side or performed by the video printer 8 side.

The patient data information is recorded in the video printer 8
Is imaged by the character generator 53 on the side,
Reconstructed. Therefore, it is possible to print a character having a size different from the character display on the side of the endoscope processor 6 or a character having a different color. This is advantageous because the data area can be made small when printing characters that require a certain size, such as Chinese characters, on the screen.

According to this embodiment, since the endoscopic image and the patient data are separated and stored in the storage area for printing, there is no need to print a blank screen when printing the monitor screen as it is. You can reduce the area,
It is possible to prevent the same patient data from being repeatedly printed when printed in a plurality of divided modes, and it is possible to print an endoscopic image in a large size suitable for diagnosis. Further, it is possible to easily enlarge and print only the endoscopic image portion, and it is possible to provide a print image suitable for diagnosis.

The endoscope processor 6 to which the electronic scope 4 is connected drives the CCD 16 in the electronic scope 4 to obtain an endoscopic image, and at the same time forms the patient data input from the keyboard 9 into an image. The image is superimposed and output, and the endoscopic image is displayed on the endoscopic image display area 7B on the monitor screen 7A, for example, as shown in FIG. 3, and the patient data mainly on the left side (and upper and lower parts) is displayed. Patient data is displayed in the display area 7C.

When the freeze switch of the scope switch 17 is operated, a freeze instruction signal is input to the image signal processing circuit 22 via the parallel I / O 34, and a still image is stored in the still image memory in the image signal processing circuit 22. It is stored and the still image is output. In this case, the moving image can be reduced and displayed in the reduced image display area 7D.

When an image is captured in the video printer 8 or printed out by an instruction from the scope switch 17 of the electronic scope 4 or the front panel 40, the instruction content is transferred to the video via the RS-232C control line 19. It is transferred to the printer 68 side.

According to this embodiment, in addition to the effect of the first embodiment, since the patient data is displayed by the bar code, the patient data can be displayed on the computer from the printed image by using the bar code reader. Easy to input (If the patient data is not displayed on the barcode, the character information of the printed patient data can hardly be read. I had to enter textual information using a keyboard, etc.).

Next, a third embodiment of the present invention will be described. The electronic endoscope system provided with this embodiment employs an endoscope processor 76 and a video printer 78 which are different in internal configuration from the endoscope processor 6 and the video printer 8 in FIG.
