Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image display device that displays images of two types of lights 1 in a superimposed manner on the same display screen, and particularly to means for positioning the two images.

In medical care, for example, the course of a disease is often diagnosed by comparing a pre-surgery X-ray photograph 7J: with a post-surgery X-ray photograph. In this case, the pre-surgery X-ray photograph and the post-surgery X-ray photograph are superimposed and observed. In order to obtain a good image for diagnosis, subtraction is necessary.

There are cases where you can view the cherry blossoms by converting it into a statue.

FIG. 1 is a professional configuration diagram of a conventional image display device that displays two types (two images) of images superimposed on the same display screen. In the figure, tA and in are image memories each having the same number of addresses, 2 is an address register, 6 is a superimposed image creation control circuit, 4 is a news checker, 5 is an information switch,
6 is a superimposed image memory, 7 is a television signal generator, 8 is a display address register, 9 is a digital-to-analog converter, and 10 cathode ray tubes.

Next, the operation of this image display device will be explained.

Different image data is written in the image memo IJ i A and 113 respectively, and the image data at the same address is read out through the address register 2 by the control signal of the superimposed image creation control circuit B, and the image memo IJ I A at that address is read out. The content of is ``10'' or ``
The information determiner 4 determines whether the content is r
Only during OJ, the contents of the image memory 113 are superimposed and written into the same address of the image memory 6. Image memory 1A
When the number 8 or the content of the address is 11, the contents of the image memo IJ I A are stored in the superimposed image r'31 memory 6.
11.

After the above operations have been performed with all addresses lit, the contents of the superimposed image memory B are read out in synchronization with the television synchronization signal and displayed on the cathode ray tube 10 through the digital-to-analog converter 9.

In such a conventional image display device, since it is necessary to use two image memories 1Δ, 113 with the same number of addresses, the overlapping operation may be complicated and difficult depending on the size of the image data. Ta.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the drawbacks of the conventional devices and to provide an image display device 61 that can easily superimpose two types of images.

The present invention has been made to achieve the above-mentioned objective 1, and its features include a reference image memory for storing reference image data, and reference one-plane image data stored in the reference image memory. a moving image memory having a large storage capacity, an information switching device that alternately switches and outputs reading of contents of the reference image memory and reading of contents of the moving image memory, and displays the output of the information switching device. A display device jσ and a means for superimposing the display base point of the base thread image data and the display base point of the moving image data recorded in the moving image memory are provided, and two types of images are superimposed on the same display screen. The purpose is to display them together.

The present invention will be described in detail above along with examples.

FIG. 2 is a diagram showing the configuration of an embodiment of the present invention in a professional manner. In the figure, 11 is a reference image memory for recording reference plane fl data, and 1] is a display base point of the base it, lz image data stored in this reference image memory 11. Reference numeral 12 denotes a moving image f3'' memory, which stores 7, t; storage capacity larger than the quasi-image data - 1, which is stored in the base thread image memory 11. For example, 1 Q is the display base point of the moving cylinder r%ξ data stored in the moving image memory 12. 16 is a display base point moving operation device for moving the front d11 display display base to a predetermined position. For example, the rightward movement switch 16A, the leftward movement switch 1311.

14■) is a reducer, 15Δ, 1511 is an address register for reading out the address of the display base point (position 2), 15A is an X-direction address register, 151 (i is a Y-direction address register), 16 (d is a reference image The display data switching speed adjustment 2 of the +71d'li'f information switching device 16 is an information switching device for switching data and moving image data to sentence n and outputting it, and for example, switching time interval: 30 mm. , <c standard switch, CH 17A, sieve speed switch, CH 171L, low speed switch 1FC, etc.

Reference numeral 18 represents a display data switching signal generation circuit for generating switching signals for information switching 11iii16, and 19 represents a display device f6.

Next, the operation of this embodiment will be illustrated in FIG.

Standard switch 1 of display data switching speed regulator 17

Then, when the display Jjj point of image [3] is set to an appropriate 111I and the data of each song 1j is read out, the information switch 16 is activated by the switching signal to display the data of both f! 30 rn data
The output is performed by changing the V pitch every m sac, and the image [ψA and li!] is displayed on the display device 619. Li statue! 3 intersects 71. will be displayed superimposed on the . At this time, if the image f'4', the display group of A, the display group of rMP and the image I3, and the point Q are displayed out of alignment, and the image ＼ and image 13 are not overlapped with each other, In order to superimpose the images of both people (!4: A, l), while looking at the screen of the display device 19, operate the predetermined push button switch of the display base point movement operation device 16 of the moving image memory 12. Move the image [3 left and right, up and down, and continue this operation until it overlaps with 13 and 3 on both sides of the screen of the display device 19.

It should be noted that the present invention is not limited to the embodiments described above, and can of course be modified in various ways without changing its purpose. For example, the display data conversion speed regulator 17 may be a continuous volume regulator. ′!
Additionally, the present invention can be applied to cases where only the regions of interest of two images are superimposed.

As described above, according to the present invention, two images of any size can be easily superimposed on each other with precision. 1. The alignment time can be done efficiently and in a short amount of time.
