Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display device for an electronic endoscope for displaying an electronic endoscope image and character information on the same screen in an overlapping manner.

[0002]

2. Description of the Related Art Generally, in an electronic endoscope, a CCD is mainly used as a solid-state image sensor at the tip of a scope. In such an electronic endoscope apparatus, when an electronic endoscopic image is displayed on the screen, the electronic endoscopic image and the patient's name as character information are displayed on the same screen in an overlapping manner. At this time,
As shown in FIG. 4 and FIG. 5, the character string of the character information can display a predetermined number of characters at predetermined positions on the left side and the right side of the screen, and when it is displayed on the left side, it is also displayed on the right side. Even when doing, the character string was displayed left-justified in the fixed character information display area.

[0003]

However, for example, in the case of a digestive tract, a general gastric scope has a diameter of about 9.2 mm, whereas a lower digestive tract scope has a diameter of about 13.0 mm. Although the diameter is different depending on the type, the number of types of CCD is limited. With a large-diameter scope, the distance between the objective lens and the CCD can be longer than with a thin-diameter scope, so when using the same type of CCD, the imaging area can be used effectively, but depending on the patient, If the character names are different and the patient name is displayed in the fixed area of the screen, the portion where the character string overlaps the electronic endoscope image becomes large. FIG. 4 shows a display screen when the display area is small, and in this case, 3 to 4 characters overlap the electronic endoscope image. Further, FIG. 5 shows a display screen when the display area is large, and in this case, 4 to 6 characters are overlapped with the electronic endoscope image.

For example, when displaying a patient name in kana characters, the number of characters varies greatly depending on the patient. Masao Suda
The name "Masao" consists of 6 characters, and 7 spaces if there is a space between the surname and the name. However, the name Kojiro Ogasawara (13 characters) consists of only 13 characters, and the space between the surname and the name is 14 characters, which requires double the character length. In addition, since patients are not only Japanese but also foreigners, the number of characters will be further increased in the case of foreigners' names. For example, in the case of FAMILY NAME called Bess Smelt Neuf, it takes 10 kana characters only. Furthermore, when displaying in English characters, in addition to FIRST NAME, FAMILY NAME, MI
Since it has a DDLE NAME, the number of characters is further increased.

In such a case, since the electronic endoscope image and the character information overlap, the image becomes difficult to see, and the character information shown in a photograph or the like becomes difficult to read.

The present invention has been made to solve the above-mentioned problems of the prior art, and an object thereof is to provide an image display device for an electronic endoscope in which an image is easy to see and character information is easy to read. It is in.

[0007]

To achieve the above object of the Invention The invention of 請 Motomeko 1 wherein, in the image display apparatus for an electronic endoscope for displaying an electronic endoscope image and character information on the same screen , lateral width of the upper and lower ends rather narrow relative to the lateral width of the central portion, and the substantially the same width vertically and the upper and lower width of the screen
Endoscopic image display means for displaying the electronic endoscopic image having the image at substantially the center of the screen, and right and left of the central portion
Without displaying the character string of the character information on the side, at least one of the upper right side and the lower right side on the screen, the character string of the character information is arranged right-justified and displayed, and Character information display means for displaying the character string of the character information arranged in a left-justified manner on at least one of the upper left side and the lower left side on the screen.

[0008]

In the image display device for an electronic endoscope of the present invention having the above configuration, since the character string of the character information displayed on the right side of the screen is arranged right justified, the electronic endoscope image and the character information are arranged. Do not overlap. Therefore, the image is easy to see and the character information is easy to read. Further, when the display area of the electronic endoscope image is large, the character string of the character information is displayed in a plurality of lines such as two lines. By doing so, even when the display area of the electronic endoscopic image is large, the electronic endoscopic image and the character information do not overlap with each other, so that an easily viewable image can be provided.

[0009]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a detailed configuration of an endoscope image processing unit and a character information display unit, which are essential parts of an embodiment of the present invention, and FIG. 2 is a diagram showing a display screen when the display area is small. FIG. 3 is a diagram showing a display screen when the display area is large.

This image display device for an electronic endoscope displays character information under the control of an image processing unit 2 for processing a video signal obtained by a CCD 1 which is a solid-state image pickup device provided at the tip of a scope and a system controller 3. By adding a signal to the character information display unit 4 to be displayed, the color monitor 5
I am trying to display it. The system controller 3 is composed of a microcomputer.

In FIG. 1, the video signal obtained by the CCD 1 is amplified by the preamplifier 6 in the image processing unit 2 and then A /
It is added to the D converter 7 and converted into a digital video signal. This digital video signal is temporarily stored in the first register 8 and then sequentially written in the frame memory 9. The digital video signal read by the frame memory 9 is temporarily stored in the second register 11 after being subjected to gamma correction by the gamma circuit 10, and then converted into an analog R signal by the D / A converter 12.
(Red), G (green), B (blue) are converted into three primary color video signals and sent to the color monitor 5. The image processing unit 2 is controlled by the system controller 3 such as pixel positions and electronic masks.

On the other hand, in the character information display section 4, the HD sync signal is sent from the TV sync generator 13 to the vertical address counter 14, and the 4FSC component is sent to the horizontal address counter 15. Then, the vertical address from the vertical address counter 14 and the horizontal address from the horizontal address counter 15 are set in the character code memory 16. This character code memory 1
The set contents of 6 are read by the character generator 17 under the control of the CHR signal of the system controller 3. It is also possible to display the character information in colors.
That is, the character generator 17 shows the set contents read from the character code memory 16 in the color table 18, so that the color table 18 associates the color data designated by the system controller 3 with the D / A converter 12 of the image processing unit 2. Can be added to.

The present invention is characterized by a procedure for writing a character code from the system controller 3 to the character code memory 16. When actually writing a character on the monitor screen, the cursor is displayed on the screen. In the conventional display method, the position of the character was predetermined, so the character was input from the keyboard of the endoscope device according to the cursor instruction of the system controller. . As a result, the characters are written by writing a code in the character code memory from the system controller 3. The way to point this cursor is characteristic. The left side of the screen may be written in the character code memory 16 in order from the left side in correspondence with the address. That is, the cursor is moved to the right.

However, since the characters on the right side of the screen overlap with the image, it is preferable that the right side of the screen be placed on the right side as much as possible. Therefore, in the present invention, the characters on the right side of the screen are displayed right-justified, and the cursor is at the right end. That is, only the cursor is written in the character code memory 16. When the first character is written, the character just written and the cursor are displayed on the left side of the cursor.
After that, the input character moves to the left for each character input. That is, the character code memory 16 corresponding to the address
Write in. When you press the space key, the cursor moves down one line.

The same applies when characters are exchanged with an external computer such as a filing device. Character information is communicated, but characters displayed on the right side of the screen, such as a name, are displayed with a line break when the system controller identifies a space.

Therefore, the character information can be displayed at any position on the screen under the control of the system controller 3. If the number of characters that can be displayed in one line is 10 as shown in Fig. 2 where the display area is small, 3 if the character string is left justified
Although ~ 4 characters are overlapped with the electronic endoscopic image, since they are right-justified, they are not overlapped with the electronic endoscopic image, and the image is easy to see and the character information is also easy to read. Further, when the display area is large as shown in FIG. 3, if the character information is divided into two lines and displayed, the electronic endoscopic image and the character information can be displayed without overlapping.

In the image display device for an electronic endoscope according to the above-mentioned embodiment, the character strings of the character information displayed on the right side of the screen are arranged right justified and displayed in a plurality of lines. Therefore, the electronic endoscope image and the character information do not overlap each other, so that the image is easy to see and the character information is also easy to read. Therefore, the operator does not need to use extra labor, and the time required for the inspection can be shortened.
