Abstract

PURPOSE:To obtain accurately an image data of a required part by means of a simple operation in a short time by forming a means designating an arbitrary part in an endoscope image displayed on a displaying means and a data damp means which can make an image data in an image region corresponding to a designated part into a numerical value and make it possible to display it. CONSTITUTION:When a function for data damp displaying is selected, a square cursor 52 is displayed on a monitor 20 for image reproduction displaying an endoscpe image 51. This cursor 52 is movable by a cursor corresponding to a size of 20X20 dots. Then, when the cursor 52 is moved to an arbitrary position wherein a data damp display is required, a judgement indicating data damp at that position is performed by pushing a button of a mouse. Then, when data damp display is performed, a data in a cursor 52 in an endoscope image data of the designated component is transferred to a user RAM etc., for example, it is made into a numerical value of 0-255 by designating it as either an image data R, G or B and it is damp-displayed on a monitor 12 for a personal computer.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an endoscopic image processing device that is capable of displaying image data of a designated area in an endoscopic image.

[Prior Art] Recently, there has been an increasing need to apply image processing in the field of endoscopy. Although general-purpose image processing devices have been used until now, they are not easy to use when incorporated into the flow of endoscopy.

This is because it is necessary to develop a new program to perform the desired image processing.

On the other hand, there are dedicated image processing devices that perform specific processing.
When a user wants to try other types of image processing, one of the general-purpose image processing devices does not have a function that can be used freely.

For example, in recent endoscopy, image filtration has become more important.

In this case, an image filling system that connects the imaging devices via a network has been proposed, but connecting the devices via a network increases the overall system configuration and poses problems in terms of cost. be. In order to improve this point, a method has been proposed in which data is transferred using a recording medium such as an optical disk. This method employs a data transfer method in which data is exchanged using optical disks.

It is desirable to realize an image processing device that is easy to use when administering endoscopy using this data delivery method.

By the way, in the conventional device, as shown in FIG.
To obtain image data within a specific region 102 from the endoscopic image 101 displayed on the screen, specify a line 103 that crosses the specific region 102 and view it on the profile graph 104, or display the image data. I was outputting it to a printer and looking at it.

[Problems to be Solved by the Invention] When viewed using the profile graph 104, there is a drawback that highly accurate image data cannot be obtained. Also,
It is not possible to know the image data of a portion that deviates from the specified line 103. On the other hand, if the output is sent to the printer,
The disadvantage is that it takes time to print out. Further, it is difficult to immediately know where the image data of a specific part 102 is printed.

The present invention has been made in view of the points mentioned above, and an object of the present invention is to provide an easy-to-use endoscopic image processing device that allows image data of a desired region to be easily obtained.

[Means and effects for solving the problem] The present invention includes a means for specifying an arbitrary part in an endoscopic image displayed on a display means, and a numerical display of image data in an image area corresponding to the specified part. By forming and covering the data dumping means that enables this, image data of a desired region can be accurately obtained in a short time with a simple operation.

In this embodiment, when the data dump display mode is selected, the image playback F-20 that displays the endoscopic image has the following:
A frame of a certain size is displayed, and the position of this frame can be moved, for example, with the mouse 31. When the position of the frame is specified with the mouse 31, the endoscopic image data at the position of the frame is digitized and displayed on a computer. The feature is that it can be displayed on the monitor 12.

Next, the function of dumping and displaying data on the personal computer monitor 12 as shown in FIG. 5, that is, the data dump display function, will be explained below with reference to the algorithm shown in FIG.

When the data dump display function is selected, the endoscope image 5
The image reproduction monitor 2o that displays 1 is shown in FIG. 5(a).
A square frame 52 is displayed as shown in (process Pi in FIG. 1). This frame 52 is a frame corresponding to a size of, for example, 20×20 dots. This frame 52 can be moved, for example, using the mouse 31 (process P2 in FIG.
). After moving the frame 52 to an arbitrary position where the data dump display is desired, a decision is made to press the right button of the mouse 31 to instruct f-ta dump at that position (R
3 process). Next, when displaying the data dump, R,
By specifying whether it is G or 8 image data (process R4), the data within the frame 52 in the endoscopic image data of the specified component is stored in the RAM 26B.
After being transferred to, for example, a numerical value of 255 to O, the data is dumped and displayed on the personal computer monitor 12 as shown in FIG. 5(b) (process P5 in FIG. 1). If you want to perform a rough data dump for other endoscopic image parts,
If you instruct not to terminate, the display of the dumped data disappears, so the operations from process 2 onwards will be repeated. Furthermore, when an instruction to end is given (process P6), this function of displaying the f-tadam button ends.

According to this embodiment, by moving the frame 52 to a desired location and instructing dumping, the computer monitor 1

Furthermore, since the data can be easily and accurately known, subtle changes in the image can also be easily known.

Further, the endoscopic image before image processing and the processed image after image processing may be dumped and displayed simultaneously (or alternately). For example, one image may be RA
If the above-mentioned frame 52 is moved to a desired position in either the pre-processing or post-processing endoscopic image after saving to the M disk 14, etc., and instructing dump display, - Read out the image data of the designated frame 52 from the image data in the image memory 19, read out the image data corresponding to the frame 52 for the other image, and display it on the PC monitor 12 at the same time, for example, before processing. It may also be possible to make it easier to identify changes in image data between before and after processing.

Note that the size of the frame 52 may be variably set by the user.

Also, instead of the frame 52, a point or a circle of a certain size may be displayed, and if a point or other position is specified, image data of the surrounding area including the point etc. may be displayed as a dump. You may do so.

In addition, when dumping image data, process P in Figure 1
In addition to what is shown in 5, for example, the sum of R, G, and B pixel data or luminance data may be selected.
