The present invention relates to an improvement of an electronic endoscope device having a function of recording on a recording medium such as (VFR).

(Prior Art) Conventionally, when recording an endoscopic image on a recording medium such as a photograph or VFR, this type of electronic internal mm device records the endoscopic image and various characters projected on the display screen of a monitor. It was intended to be recorded as is on the recording medium.

However, among the various characters on the display screen of the monitor, there are some characters that do not need to be kept as records. Furthermore, if an endoscopic image is recorded with a large number of characters, the characters will be small and extremely difficult to read, especially when directly viewing a negative or positive film.

(Problems to be Solved by the Invention) Therefore, in the case of this type of conventional electronic endoscope device, when viewing a photograph or an endoscope image recorded on a VFR, it is difficult to refer to a desired character. This resulted in problems such as characters being annoying and characters being ignored.

The present invention has been made in view of the above circumstances, and its purpose is to erase unnecessary characters from an endoscope image displayed together with various characters on a display screen, and to Can images be recorded on a recording medium electronically? Our objective is to provide a JA mirror device.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention creates moving images and still images based on video signals obtained by imaging the inside of a body cavity of a subject. In an electronic endoscope device that displays these endoscopic images on a display screen along with various characters such as the subject name and ID number, characters are displayed in response to a predetermined input operation to select a character that is not to be recorded. Character exclusion setting means for setting exclusion from recording targets; and recording an endoscopic image excluding characters set by the character exclusion setting means on a recording medium such as a photograph or VFR in response to a predetermined recording instruction operation. The gist thereof is to include a recording control means for performing control.

(Function) In the electronic endoscope device according to the present invention, unnecessary characters are erased by the recording control means under the condition that the character exclusion setting means sets the desired character to be excluded from recording. Control of recording endoscopic images on a recording medium can be performed.

Therefore, when a recording instruction operation is performed, unnecessary information,
The endoscopic image can be recorded on the recording medium with patient data or all characters erased.

(Embodiment) FIG. 1 is a block diagram schematically showing an electronic endoscope apparatus according to an embodiment of the present invention.

Is the electronic endoscope device of this embodiment inserted into the body cavity of the subject? ! This device is used to observe the inside of a body cavity with the guide section 2 of the mirror scope introduced.
The device includes a /A converter 6, a video display position control circuit 7, an image composition circuit 8, an encoder/RGB matrix circuit 9, a character display circuit 10, a keyboard 11, and a controller 12 for controlling these parts. Then, the output of the encoder/RG8 matrix circuit 9 is sent to the monitor 13, A
- This configuration is added to the ml heating device 14 and vFR 15.

The CCU 3 converts an electrical signal obtained by imaging a specific site within the body cavity with the endoscope 1 into a video signal.

The video signal from the CCU 3 is digitized by the A/D converter 4 and sequentially written into the frame memory 5 under write control by the controller 12. frame memory 5
The video signal data sequentially written into the D/A J! The signal is converted into an analog signal by a percentage unit 6 and sent to an image synthesis circuit 8 via a video display position control circuit 7.

On the other hand, a character data signal is transmitted from the character display circuit 10 to the image synthesis circuit 8 under drive control by the controller 12.
sent to.

Therefore, in the image synthesis circuit 8, the video signal and the character data signal are synthesized, and this synthesized signal is sent to the encoder/RGB matrix circuit 9.

Therefore, the output of the encoder/RGB matrix circuit 9 is displayed on the monitor 13. The JA1 image can be displayed together with various characters.

Further, when the image is frozen, the content displayed on the monitor 13 can be photographed using the output of the encoder/RGB matrix circuit 9 using the hard copy device 14.

Further, when a moving image is displayed on the monitor 13 in real time, the contents displayed on the monitor 13 can be captured on video film by the VFR 15 using the output of the encoder/RGB matrix circuit 9.

In addition to the basic functions that allow you to display and record a series of images,
One embodiment of the present invention provides controller 12 with additional new functionality.

That is, in one embodiment of the present invention, the controller 12
has the function of a character exclusion setting means that, when an operation for selecting a character not to be recorded is performed on the keyboard 11, sets the character to be excluded from being recorded in response to this selection operation.

It also has a function as a recording control means for controlling the character display circuit 10 in response to an operation of pressing the copy switch 16 of the endoscope 1 to control the character display circuit 10 in accordance with the setting contents of the character exclusion setting means.

Therefore, when the copy switch 16 of the endoscope 1 is pressed, the character display mode on the monitor 13 is changed from the normal number of characters to the number of characters when the copy is ON, as shown in FIG. .

At this time, if the image is frozen, copy ON as shown in Figure 2.
The characters are recorded together with the endoscopic image as a photograph by the hard copy device 14 with the reduced number of characters at the time.

Furthermore, when displaying a real-time image, characters are recorded on the video film by the VFR 15 along with the endoscopic image using the number of characters shown in FIG. 2 when the copy is turned on.

Further, since all of the various characters can be excluded from recording by the character exclusion setting means of the controller 12, it is possible to exclude all of the various characters from being recorded, especially when recording an image in which the conveyance scene changes sequentially, such as a real-time image, with the hard copy device 14 or VFR 15. First, the system can be configured such that only the characters are recorded on the video film and then the images are recorded sequentially without the characters. The recording mode is shown in FIG.

As described above, according to the embodiments of the present invention, endoscopic images recorded in photographs or VFRs can have only the desired number of characters recorded. Characters in endoscopic images that were previously displayed are now easier to see.

Furthermore, since it is possible to continuously record endoscopic images from which all characters have been deleted, easy-to-read continuous images can be reproduced by simply recording the characters at the beginning.

[Effects of the Invention] As explained above, the electronic endoscope device to which the present invention is applied can delete unnecessary arbitrary characters as a record when copying is turned on and record it on a recording medium such as a photograph or VFR. This has the advantage that it is possible to record endoscopic images in a character-reduced state and make them easier to see.
