Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an endoscopic video device using an electronic endoscope incorporating a solid-state image sensor.

[Prior Art] An endoscope video device is configured to process an image signal obtained from an electronic endoscope using a video processing circuit of an endoscope light source device, and display the video signal on a monitor. There is. The video signal can also be recorded by inputting it into a plurality of external recording devices, such as an image file device, an electronic camera, or a hard copy device. When images are recorded on these external recording devices, the number of images recorded for each recording device is displayed on the monitor.

[Problems to be Solved by the Invention] According to conventional endoscopic video devices, the display of the corresponding number of recorded images is updated each time the recording operation of each external recording device is completed. Since the time required for recording differs, the update timing of the recorded number display differs for each external recording device. This will be different from the updated sheet count display value regarding the device. For this reason, the correct number of recorded sheets may not be obtained.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an endoscopic video apparatus that prevents the display of the number of recorded images from being updated until all external recording devices have completed recording.

[Means and effects for solving the problem] According to the present invention, in an endoscopic video apparatus including a plurality of external recording means for recording transendoscopic images and a video processing section having a function of displaying the number of recorded images, , the endoscopic video processing section includes means for sending recording start signals to at least two external storage means, detecting completion of recording of the external recording means, and responding to recognition of completion of all recordings of the external recording means. An endoscopic video apparatus is provided, comprising: means for updating the display of the number of recorded images. According to this apparatus, the display of the number of recorded sheets is not updated until recording by all external recording means is completed, so that the number of recorded sheets by each external recording device will not differ from the regular number of sheets.

[Embodiment] In the embodiment of FIG. 1, the video signal output terminal of the electronic endoscope 1 is coupled to the video processing circuit 3 of the video endoscope light source device 2. Video processing circuit 3
The output terminal of is connected to the video memory 5 via an A/D converter. The output terminal of this video memory 5 is connected to an adder circuit 7 via a D/A converter 6.

An output terminal of a keyboard 8 for inputting patient data, search data, etc. is connected to a character memory 9.
This character memory 9 is coupled to a reading circuit 10, and the read character data is input to the adding circuit 7 via a D/A converter 11. The output terminal of the adder circuit 7 is the monitor 12 and the image file device 1.
3. Connected to electronic still camera 14 and monitor screen hard copy device 15; Image file device 13, electronic still camera 14, and monitor screen hard copy device 15 are coupled to CPU 16 via signal lines and I/O ports 17. CPU1
6 sends and receives a recording start signal and a recording completion signal via an I/O port 17. In addition, since the recording time of the hard copy device 15 is constant (approximately 2 seconds), there is no need to output a recording end signal, and the CPU 1
In step 6, the recording completion time is determined.

CPU 16 is coupled to ROM and RAM;
Control the device according to the recording program of the RAM
The search data and recording number data are recorded in the .

In the video endoscope device described above, when the video endoscope light source device 12 is powered on, the CPU 1
6 starts its operation, and data on the number of recorded sheets of the external recording devices from the previous inspection, that is, the image file device 13, the electronic still camera 14, and the monitor screen hard copy device 15, is read from the RAM and transferred to the character memory 9. The recording number data stored in the character memory 9 is read out by the readout circuit 10,
The signal is input to the adder circuit 7 via the D/A converter 11. Since the video signal of the electronic endoscope 1 is input to the adding circuit 7 via the video processing circuit 3, A/D converter 4, video memory 5, and D/A converter 6, the number of recorded sheets character data is It is combined with the transendoscopic image and input to the monitor 12. Therefore, as shown in FIG. 2, the monitor 12 displays the number of recorded images from the image file device 13, electronic still camera 14, and monitor screen hard copy device 15, as well as transendoscopic images, V.DISC, AUX, and H.
Displayed along with the COPY head display.

When the endoscope operator observes the image on the monitor 12 and the image that he wishes to record on the external recording device is displayed on the monitor 12, the operator operates the release switch 18 of the electronic endoscope 1. At this time, a release signal is input from the electronic endoscope 1 to the CPU 16.
In response to the release signal, the CPU 16 sends a recording start signal as shown in the time chart of FIG. 3 to the image file device 1 via the I/O port 17.
3. Output to the electronic still camera 14 and monitor screen hard copy device 15. FIG. 4 is a flow chart showing the operation from generation of a release signal to output of a recording start signal to the image file device 13, electronic still camera 14, and monitor screen hard copy device 15.

Image file device 13, electronic still camera 14
Recording is started in response to a recording start signal sent to the monitor screen hard copy device 15. That is, the image file device 13 records the endoscopic image on an empty track of the recording disk, and the electronic camera 14 records the image on an empty frame. The hard copy device 15 also prints the image on paper. When the image file device 13 and the electronic still camera 14 complete image recording of one frame, a recording completion signal is sent to the CPU 16.
Output to. The CPU 16 recognizes the completion of recording by the image file device 13 and the electronic still camera 14 by receiving the image completion signal. Hardcopy 15 completes recording after 2 seconds, but the timing of this completion is
The CPU 16 recognizes this when two seconds have elapsed since the recording start signal was generated.

When the CPU 16 recognizes that all recording is complete, it updates the number of images recorded in the image file device 13, electronic still camera 14, and monitor screen hard copy device 15. In this case, the number of recorded sheets in the character memory 9 is updated, and the updated number of recorded sheets in the character memory 9 is input to the monitor 12, thereby updating the display of the number of recorded sheets. In the case of the image file device 13, the track number may be displayed as the number of recorded sheets instead of the number of recorded sheets.

As described above, transendoscopic images are recorded, and the display of the number of recorded images is sequentially updated when the recording operation of the external recording device that takes the longest recording time is completed. When recording of the necessary images is completed, the final number of images to be recorded in the image file device 13, electronic still camera 14, and monitor screen hard copy device 15 is recorded in the RAM. To update the character memory 9, the number of recorded sheets is updated when each recording device completes recording without waiting for the last external device to complete recording, and the updated record data is read from the character memory 9 when the last recording device completes recording. The recorded number display may be updated.

[Effect of the invention] When recording image information on external recording devices with different recording times, the number of recorded sheets is not updated until recording is completed on the recording device with the longest recording time, so that the number of recorded sheets on different recording devices is normal. It will no longer show a value different from the value of .
