Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an endoscopic video apparatus using an electronic endoscope.

[Prior Art] When recording a radial endoscope image captured by an electronic endoscope with a built-in solid-state image sensor in an image filing device, a search is required to retrieve the radial endoscope image at a later date. Data is input from an image filing device. Since the image filing device is remote from the electronic endoscope, inputting search data requires traveling back and forth between the image filing device and the electronic endoscope. In order to eliminate this inconvenience, a communication function is provided between the endoscope light source device to which the endoscope is connected and the image filing device, search data is input from the endoscope light source device, and this data is transmitted through the communication line. Endoscopic video equipment has been developed that transmits images to an image filing device via a video camera.

[Problems to be solved by the invention] An endoscopic video device equipped with a communication function enables
Although this eliminates the need to move back and forth between the image filing device and the electronic endoscope, it is often the case that people forget to input search data from the endoscope light source device, and the search data is not recorded and may be returned later. This causes the inconvenience that it becomes impossible to search for endoscopic images.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an endoscopic video device having a function of preventing images from being recorded in an image file device unless search data is input.

[Means and effects for solving the problem] According to the present invention, as shown in FIG. 1, a video endoscope light source device (video processor) 2 connected to an electronic endoscope 1 processes search information. a search data input determining means 4 for determining whether or not search information has been input from an input means for inputting search information; a communication means 6 for communicating with an image file device 7 serving as an endoscopic image record retrieval device; An endoscopic video apparatus is provided which includes a warning means 5 for warning of no information input. When the search data is not input, a warning is issued by the warning means 5 or a warning display is issued by the display means 8, so that image information is not recorded without the search data attached, and search failure does not occur during the search.

[Embodiment] According to the endoscope video device shown in FIG. 2, the image output terminal of the electronic endoscope 11 is coupled to the video processing circuit 13 of the video endoscope light source device 12. An output terminal of video processing circuit 13 is connected to video memory 15 via an A/D converter. An output terminal of the video memory 15 is connected to an adder circuit 17 via a D/A converter 16.

A keyboard 18 for inputting search data is connected to a character memory 19. Data is read out from this character memory 19 by a readout circuit 20, and output terminal 20 of the readout circuit is connected to the addition circuit 17 via a D/A converter 21. Summing circuit 17 is coupled to image file device 22 and monitor 23.

The output terminal of the keyboard 18 is the electronic endoscope 11
It is connected to the CPU 24 together with the release signal output terminal. An output terminal of the CPU 24 is connected to a buzzer 25, a communication circuit 26, and a character memory 19. The communication circuit 26 is the communication circuit 1 of the image file device 12.
Connected to 7. The CPU24 further includes ROM and
RAM28 is connected.

In the endoscope video device having the above configuration, when the video endoscope light source device 12 is powered on,
The CPU 14 starts operating, and the item names (ID.NO, NAME, DOBIRTH) of the search data are input into the character memory 19 according to a predetermined format. The item name of the search data input into the character memory 19 is read out by the readout circuit 20,
The signal is converted into an analog signal by the D/A converter 11 and input to the adder circuit 17 .

On the other hand, the image signal of the electronic endoscope 11 is processed by the video processing circuit 13 and stored in the video memory 15 via the A/D converter 14.
Video data in the video memory 15 is converted into an analog video signal by a D/A converter 16 and input to an adder circuit 17. The adding circuit 17 adds the transendoscope video signal and the item name signal, and inputs the added signal to the monitor 23 for display as shown in FIG. 3, and also inputs it to the image file device 22.

The user inputs search data via the keyboard 18 while observing the image shown in FIG. In this data input, when entering the date of birth (BIRTH), 1 or more for Showa (S), 1 to 15 for Taisho (T), and 1 to 45 for Meiji (M).
The month is represented by 1 to 12, and the day is represented by 1 to 31.

The input search data is input to the character memory 19 and stored. The search data read from the character memory 19 is combined with the transendoscopic image and displayed on the monitor 23. Search data input from the keyboard 18 is input to the CPU 14, stored in the RAM 28, and transmitted to the image file device 22 via the communication circuit 26.

While observing the screen of the monitor 23, the user finds the endoscopic image that he or she wishes to record, and then displays the electronic endoscope 11.
Activate the release switch 29 provided at the.
A release signal generated at this time is transmitted to the CPU 24. When the CPU 24 receives the release signal, it executes an operation for determining the presence or absence of search data according to the flowchart shown in FIG. That is, by checking whether the search data has been recorded in the RAM 28 before the release operation is performed, it is determined whether the search data has been input.
If this determination is YES, the CPU 24 transmits a release signal to the image file device 22 via the communication circuits 26 and 27. The image file device 22 records a desired endoscopic image on a recording medium together with search data in response to the release signal.

If the search data input determination is NO, that is, if the search data is not stored in the RAM 28, the CPU 24 causes the buzzer 25 to sound for 5 seconds and inputs the characters "NO DATA" into the character memory 19. This character "NO DATA" is read out by the readout circuit 20 and supplied to the monitor 23 via the D/A converter 11 and the addition circuit 17. The monitor 23 displays the characters "NO DATA". This display and the sound of the buzzer 25 warn the user that no search data has been input. Once the user receives this warning, the user can enter search data via the keyboard.

[Effect of the invention] Determine whether search data is input or not,
If no search data is input, a warning is issued to prevent the radial endoscope image from filing, thereby preventing unsearchable images from being recorded during the search.
