Description

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

[Prior Art] An endoscopic 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. The video signal can also be recorded by inputting it to 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 the conventional endoscopic video device, the display of the corresponding number of recorded images is updated every time the recording operation of each external recording device is completed. Because the time required for recording differs, the update timing of the number of recorded sheets display differs for each external recording device, and the number of recorded sheets displayed on the external recording device that completed recording last, for example, a hard copy device, is different from that of other external recording devices. The updated number of sheets displayed will be different from the displayed value. For this reason, the correct number of recorded sheets may not be obtained.

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 recording by all external recording devices is completed.

[Means and effects for solving the problems] 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 a recording start signal to at least two external recording/recording means, detecting completion of recording of the external recording means, and responding to recognition of completion of recording of all the external recording means. and means for updating the display of the number of recorded images. According to this device, 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 unit does not differ from the regular number of sheets.

[Embodiment] In the embodiment shown in FIG. 1, the video signal output terminal of the electronic endoscope 1 is connected to the video processing circuit 3 of the video endoscope light source device 2.
is combined with An output terminal of the video processing circuit 3 is connected to a 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 adding circuit 7 is a monitor 12, an image file device 13, and an electronic still camera 14.
and a monitor screen hard copy device 15.

The image file device 13, electronic still camera 14 and monitor screen hard copy device 15 are connected to the signal line and I10.
It is coupled to CPU 16 via port 17 . CPU
16 sends and receives a recording start signal and a recording completion signal via the I10 boat 17. In addition, hard copy device e11
Since the recording time is constant (approximately 2 seconds), the recording completion time is determined at CP tJ 16 without requiring the output of a recording end signal.

The CPU 16 connects the ROM and RAM, controls the device according to the recording program in the ROM, and records search data, recording number data, etc. in the RAM.

In the above-mentioned endoscope video apparatus, when the power of the video endoscope light source device 12 is turned on, the cpu 16 starts operating, and the external recording device of the previous examination, that is, the image file device 13, Data on the number of recorded images of the electronic still camera 14 and 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 a readout circuit 10 and input to the addition circuit 7 via a 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 images 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 transendoscopic image as well as the image file device W13,
The number of recorded images of the electronic still camera 14 and the monitor screen hard copy device 15 are V, DISC, AIJX, and H, respectively.
Displayed together with the 6C0PY head display.

When the endoscope operator observes the image on the monitor 12 and the image that he wants 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, the release signal from the electronic endoscope 1 is CP
Input to U16. In response to the release signal, the CP IJ 16 outputs a recording start signal as shown in the time chart of FIG. 3 to the image file device 13, electronic still camera 14, and monitor screen hard copy device 15 via the I10 boat 17. . FIG. 4 shows the sequence from release signal generation to image file device 13 and electronic still camera 1.
4 and monitor screen hard copy device @15 note @If
The flowchart shows the output operation of the ll start signal.

The image file device 13, electronic still camera 14, and monitor screen hard copy device 15 start recording in response to the recording start signal. That is, the image file device 13 records transendoscopic images on empty tracks of the recording disk, and the electronic camera 14 records images on empty frames. The hard copy device 15 also prints the image on paper. When the image file device 13 and the electronic still camera 14 complete recording of one frame of image, a recording completion signal is sent to CPU.
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. The hard copy 15 completes recording after two seconds, and the CPU 16 recognizes this completion time when two seconds have elapsed since the generation of the recording start signal.

When CPU ie recognizes that all recording has been completed, it updates the number of recorded images in the image file device W113, 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 recordings instead of the number of recordings.

Transendoscopic images are recorded as described above, and the display of the number of recorded images is sequentially updated at the time when the recording operation of the external recording device with the longest recording time is completed. When the recording of the necessary images is completed, the final number of recorded images of the image file device 13, electronic still camera 14, and monitor screen hard copy device 15 is set to RA.
Recorded in M. 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 recording number data is read from the character memory 9 when the last recording device completes recording. , the number of recorded images 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 .
