FIG. 1 shows the configuration of an electronic medical record apparatus according to an embodiment. As shown, the electronic medical record device has a control device 20, a keyboard 11, a mouse (or other known pointing device) 12, a display 13, and a storage device 30. The control device 20 includes a program ROM, a working RAM, an MPU, a video RAM, and the like. Functionally, a system control unit 21 having a control function of the entire apparatus, a display control unit 22 having a display control function of the display 13, and a file recording / reproducing unit 2 having a function of reading / writing each file in the storage device 30.
3 The storage device 30 is configured as a device having a recording medium such as a hard disk, for example. The storage device 30 stores medical images, such as radiographs, endoscopic photographs, ultrasonic echo photographs, and photographs taken by a CT scanner, in association with acquisition (entry or examination) dates. The storage device 30 also stores a medical information file and the like in addition to the image file 31, but is not shown because it does not directly relate to the gist of the present invention.

In the illustrated device, a plurality of medical images are selected by a user (physician) input, and when a mode for displaying the plurality of medical images on the same screen is instructed, first, each of the selected images is displayed. The associated date information (the date of photographing of the image in the case of a photograph, the date of entry in a medical chart in the case of a schema) is read out and sorted in chronological order. Is done.

Next, the aspect ratio (horizontal: vertical) of the plurality of selected images and the aspect ratio (horizontal: vertical) of the display screen are compared. It is determined whether they are arranged side by side or arranged side by side.

That is, when the shape of the medical care image is a horizontally long image than the shape of the display screen, it is better to arrange the medical treatment image in the vertical direction.
Since each image can be displayed in a larger size than when arranged side by side, (a) As shown in the left column of FIG. 2, the aspect ratio Ra of the selected image is larger than the aspect ratio Rm of the display screen. large

In the case of Ra> Rm (1), the arrangement direction of a plurality of selected images is determined to be "vertical direction". In addition, when the shape of the display screen is a horizontally long image than the shape of the medical care image, it is better to arrange them side by side,
Since each image can be displayed in a larger size than arranging it vertically, (b) as shown in the right column of FIG. 2, the aspect ratio Rb of the selected image is larger than the aspect ratio Rm of the display screen. small

In the case of Rm> Rb (2), the arrangement direction of a plurality of selected images is determined to be “horizontal direction”. (C) If the selected image and the display screen have similar shapes with the same aspect ratio, they are the same even if they are arranged in any direction. Therefore, the default direction set in the electronic medical record apparatus is set as the arrangement direction. It is determined. The above functions correspond to the arrangement direction determining means in the claims.

In the illustrated apparatus, when the display magnification is not specified in displaying the selected image as described above, all of the selected images may be perfectly fit on the display screen without excess or deficiency. The maximum magnification is determined as the display magnification while all the selected images arranged in the determined arrangement direction fit within the display screen.

That is, when a plurality of selected images are arranged in the vertical direction, as shown in the upper section of FIG. 3, the vertical size Ha of the selected image, the vertical size Hm of the display screen, and the total number n of the selected images are determined. ,

X = (Hm / n) / Ha (3) is determined as the display magnification. When a plurality of selected images are arranged side by side in the horizontal direction, as shown in the lower part of FIG. 3, the horizontal size Wb of the selected image and the vertical size Wm of the display screen are set.
, And the total number n of the selected images,

X = (Wm / n) / Wa (4) is determined as the display magnification. The above functions correspond to the display magnification determining means in the claims. The main part of the processing procedure that functions as the arrangement direction determining means and the function as the display magnification determining means is shown in the flowcharts of FIGS.

On the other hand, when the display magnification of the selected image is specified in advance by the input of a user (doctor) or the like, the display at the automatic magnification automatically set by the above equation (3) or (4) is performed. When a change in the display magnification is instructed by the input of the user or the like after the operation is performed, the display is performed at the designated magnification instructed. At that time, the position of each image is determined such that the center of the center image (the image in the middle in the arrangement order) in the selected image matches the center of the display screen. This function corresponds to the function of the display control means specified in claim 4. Note that control may be adopted in which the most desired image is selected and the center of the image is matched with the center of the display screen.

In the case where the center of the center image is made coincident with the center of the display screen, if the designated magnification is larger than the automatic magnification, the image located at the peripheral portion or a part thereof may not fit within the display screen. Disappears. It should be noted that this problem can occur substantially in the same manner even when the control for matching the center of the image to be most viewed with the center of the display screen is employed. In such a case, the present apparatus does not display the entire image causing the image loss (see the upper part of FIG. 4), or displays part of the image while allowing the image loss (see the lower part of FIG. 4). Is arbitrarily selectable by the user.

[0014] That is, it is easier to grasp the medical condition, etc., without looking at the image in which the image loss has occurred, or it is easier to grasp the disease condition, etc., even if the image loss occurs, by visually recognizing as many images as possible at once. Is different depending on the purpose of use, the manner of use of the user, and the like, so that the user can select and input one of the modes (complete display mode / incomplete display mode). The mode input means described in the claims is realized by a function that the mouse 12, the display 13, the display control unit 22, and the system control unit 21 play together in the configuration of FIG. For example, it is realized by an operation of placing a pointer on any one of the mode selection buttons displayed on the display and depressing the mouse 12 with a single click. The main part of the above processing procedure is shown in the flowchart of FIG.

[0015]

According to the present invention, the arrangement direction of the selected image is determined based on the comparison result of the aspect ratio of the selected image (such as an X-ray photograph and an endoscopic photograph) and the aspect ratio of the display screen. The display magnification of the selected image is determined based on each size of the selected image and the display screen and the number of the selected images, and the selected images are arranged in the arrangement direction and displayed at the display magnification.
