Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image display device that displays images 11 of categories 2, 1-0 in a superimposed manner on the same display screen] 7.
The present invention relates to image positioning means.

In the medical field... frogs, for example, surgery Aft's XP? The progress of the disease is often diagnosed by comparing the photo and the post-surgery XIf# photo. In this case, the pre-surgery X-ray photograph and the post-surgery X-ray photograph are superimposed and observed. In addition, in order to obtain a good image for diagnosis, the image may be converted into a Zabutrak/Yon image and observed.

FIG. 1 is a professional configuration diagram of a conventional image display device that displays two types of images superimposed on the same display screen. In the figure, jA and 1F-1 are image memories each having the same number of addresses, 2 is an address register, 6 is a superimposed image 1ψ creation a control circuit, 4-digit information judge, 5 and 1 information switch, 6 IQ A superimposed image memory, a 7-digit television synchronization signal generator, 8 a display address register, 9 a digital-to-analog converter, and 10 a Brown trade mark.

Next, the operation of this image display device will be explained. Both different rt data are stored in the image memories 1A and 113, respectively, and the image data at the same address is read out through the address register 2 by the control 11 signal of the superimposition creation control circuit 16, and its atte l/ picture r3

In such a conventional image display device, since it is necessary to use two image memories IA and ill with the same number of addresses, the overlapping operation may be extremely difficult depending on the size of the image fψ data.

The purpose of the present invention is to eliminate the drawbacks of the previous device (2) and
To provide an image display device capable of accurately and easily superimposing one field of different types of images.

The present invention has been made to achieve the above object, and its characteristics include a reference image memory for storing (?) quasi-both image data, and an image memory for the base ((, A moving image memory having a larger arrangement (5 volumes) d than the reference image data stored in the image memory, reading out the contents of the base image memory, and expanding the contents of the moving image memory.

1. It is provided with means for superimposing the display base point of TV-image data and the display base point of moving image data stored in the moving image memory, and two types of images are displayed superimposed on the same display screen.

Hereinafter, the present invention will be explained in detail in 111(1) 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, numeral 11 is a reference image 1W memory for storing the standard image data, and 1] is a display reference point of the reference image data written in the reference image memory 11. Reference numeral 12 denotes a moving image memory, which has a storage capacity larger than the reference image data stored in the base thread image memory 11, for example, a reference image (9 times the size of the elephant data).

It should be noted that the present invention is not limited to the above-mentioned embodiments, but may be modified in various ways without changing the gist thereof. Of course you can do it. For example, the present invention can be applied even when the positions of only the regions of interest in two images are superimposed.

As explained below, according to the present invention, no matter what the size of the two images, it is necessary to make sure that one image of one card is superimposed on the valley in one frame of the two images. However, it is important that the positioning be done accurately and in a short time.
