Abstract

PURPOSE:To attain surely ease of an image pickup of an overall image picture by displaying a picture being photographed and a picture prepared for photographing on a diaplay device as a profile picture corresponding to the image pickup frame position and size. CONSTITUTION:A video signal memory 7, display device 8 and a display controller 9 are provided to a remote controller 9. A frame display corresponding to the framing set to a film is applied to the picture display device 8 on which profile pictures P1-P4 of the picture after being photographed and a profile picture P5 of the picture going to be photographed from now are displayed. The display is distinguished by applying continuous display to the profile pictures P1-P4 while applying flickering display to the profile picture P5.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a medical image display method used in, for example, an imaging camera.

1. Conventional technology - Imaging cameras convert X-ray images and ultrasound images into CRTs.
The RT display image can be displayed on a display device, and the RT display image can then be photographed on film, and can even be used in medical equipment, etc. Film photography is not limited to capturing a single image using a sheet film V, but it is also possible to capture images of the related number of paddy grains separately, thereby facilitating comprehensive image diagnosis for the diagnosis target (for example, 107818).

By the way, with such an image capturing device 1), it is often necessary to forget which 5 images 91 were previously recorded on the sheet film, resulting in a blank image or a different arrangement of images. By mistake, the image of Section 191 (h) was exposed at a far distant position, making it difficult to compare (σ).

1. OBJECTS OF THE INVENTION 1. It is an object of the present invention to provide a photographing and displaying method that makes it extremely easy to take a group of mixed images.

1. Configuration of the Present Invention 1. The present invention provides a contour image by associating an image captured by an imaging camera VC and an image prepared for photographing with a photographic frame 671θ and a size. This project proposes a display in which captured images and prepared images can be distinguished from each other.In an imaging camera that divides and captures images displayed on a CRT display device by frame position and size, it is possible to display captured images and captured images separately. A medical image display method is characterized in that a prepared image is displayed on a display as a contour image in association with its photographic frame position and size.

-Example- The method of the present invention will be explained in detail below with reference to the drawings.

In FIG. 1, an image memo I71 stores image signals detected using X-rays or ultrasonic waves, and the necessary image signals are read out as needed.

The imaging camera 2 includes a CRT display device 8 that inputs an image signal stored in an image memory l as a video signal and displays it as a still image on a cathode ray tube, and a film position where a sheet film is loaded facing the CRT display device 8. It comprises an adjustment means 4 and a shutter lens 5 whose position is adjusted between the display @ 8 and the film position adjustment means 4, and the display image of the CRT display device 8 is displayed on the film whose position has been adjusted by the film position adjustment means 4. By adjusting the position of the shutter lens 5, the image is enlarged or reduced to the desired size and photographed.

The remote controller 6 controls the readout of image signals from the image memory 1, and controls the film position adjusting means 4 according to the set number of frames to be taken and the photographing frame position 1° signal. The position R1 of the shutter lens 5 is controlled, as well as film supply and take-out control.

In (iE embroidery) using an imaging camera with such a configuration, in the present invention, the beam controller 6 is provided with a video signal memory 7, an image display a8, and a display controller 9. A contour image signal is written as a contour image signal processed by signal processing 111 from a video signal given to the device 3.The image display device 8 displays a contour image according to the contour image signal read from the memory 7.Display controller 9 The controller 9 collectively processes the signal f3 of the memory 7, various controls for reading, and display control of the display 8.This controller 9 may be provided with a computer dedicated to displaying the contour image, or the remote controller 6 may be configured to use the idle time of the existing computer. Use this to ensure the desired control capability.

The display mode of the image display device 8 is as illustrated in FIG.
Contour images P□, P2. of the images that have been shot up to that point are displayed with frame borders corresponding to the frame setting set on the film.
P8. P, and the contour image P5 of the image to be photographed are displayed, and while P□ to P are displayed continuously, P5 is displayed blinking, so that the display of the photographed image and the image prepared for photographing can be distinguished. Change the display mode.

By providing such a contour image display means, in the photographing operation by the imaging camera 2, 1llllI
On the image display unit 8, the photographed image and the outline image of the pre-photographing preparation (Φ) are displayed in correspondence with the film frame position, and this image display allows the photographer to select the image frame position, select the image size, and select 0. It is easy to determine the optimum image for diagnosis, and it prevents taking the same image twice or forgetting to take it.Also, since the displayed image is the outline image of the image taken on film, a relatively small Simple display and control using the display 8 and small capacity memory 7 can be achieved.

FIG. 8 is a block diagram 1 showing one embodiment of the present invention.
The memory 7, display 8, etc. in FIG. It is shown in association with the controller 9. The video signal from the image memory 1 is sent to an analog-to-digital (A/D) converter I.
It is converted into a digital signal with the number of bits necessary for straight contour display by O and stored in the video signal memory? is stored in The horizontal synchronization signal and vertical synchronization signal attached to the video signal are respectively used as count inputs of a programmable timer 14.12, and these programmable timers 1.1 and 1.2 have a CP
Numerical values are preset from 013 through the address bus and imported using the horizontal and vertical synchronization signals σ) divisor! 1- Obtain image position designation timing signals H and V (Z). These timing signals) i and V are matched by the Nant gate 14 and made into an inhibit signal for the A/D converter 10,
A contour tilii image signal +j (digital signal) corresponding to the image of the arbitrary body i6 is extracted from the display image with the RT display price of 8. This contour image signal is stored in memory 7Vc.
), storage areas are divided according to address data from CPU 1B. The storage area of the camera is set to C according to the film frame position designation signal and frame size designation signal.
The PU 18 performs calculation extraction.

This is a read-only memory (ROM) that stores programs and data necessary for controlling up to two CPUs 1B with 15 units, and programs necessary for display control of the display 8, which will be described later.

The image display 8 has a liquid crystal dot matrix (IJ) type liquid crystal display section 16 in which horizontal electrode lines and on-duty electrode lines are arranged vertically according to the number of pixels.

A horizontal drive driver 17 and a vertical drive driver 18 that drive each electrode line, and a graph ink display controller 1
9, the controller 19 extracts the contour image data stored in the memory 7, and displays a dot at the display position specified address attached to the data. Data is given to the horizontal and vertical drive drivers 17 and 18 so as to display 111 images, and continuous display and blinking display are controlled to distinguish between photographed images and moebi-gashin.

1. Effects of the present invention - As described above, according to the present invention, images that have already been photographed and preparation images are displayed on an imaging camera as a contour image in association with the photographed frame position and size. This has the effect of making camera photography easier and more reliable.
