2. Description of the Related Art When observing an image displayed on a monitor using an image information system or the like and obtaining a certain judgment,
In many cases, an image and additional information indicating identification information or explanation information of the image are displayed as graphics such as characters or figures on the monitor. In particular, in a medical image database system that constructs an image database by connecting various medical terminal devices and workstations and the like that generate, process, and display medical image data as terminals, to diagnose symptoms of a patient who has taken an image. A doctor interprets a medical image at a time, but there are many examples in which tens of images are to be interpreted even if only one symptom of one patient is examined. Therefore, when performing image interpretation, a plurality of images (and their accompanying information) are displayed on one monitor by using an image display device or a terminal device constituting the image display device. In many cases, the user selects an application or makes a comparison with another case.

[0003] In such a case, conventionally, scrolling of an image displayed on a monitor is carried out to obtain the image shown in FIGS.
As shown in FIG. 4, an image and graphics (characters and graphics) 45 as accompanying information are moved and displayed together with the image 46 (FIG. 4A shows an image before scrolling (NO6, NO7) displayed on the monitor. , NO10, NO11), FIG. 4B shows an image during scrolling, and FIG. 4C shows a case where scrolling is stopped). As described above, in the conventional method, the image and the graphic always move at the same time.

When scrolling is performed, as shown in the process chart of FIG. 5, the moving amount of the image is set to "S".
Assuming that (vector amount S), the graphic is moved and displayed by giving a moving amount of "S".

FIG. 5 is a process chart showing a conventional image scrolling method. After scrolling is started, at step 51, the graphic accompanying the image is first erased from the screen, and then at step 52, the scrolling is performed. The moving amount “S” is calculated, and the image is moved by “S” in step 53 and displayed. In step, the graphic is moved by “S” and displayed. In step 55, it is tested whether or not there is an instruction to stop scrolling. If there is an instruction, scrolling is stopped. If no instruction has been issued, steps 51 to 55 are repeated to continue scrolling. In such a scroll system, by repeating Steps 51 to 55, the image and the graphic appear to the operator's eyes as if they are displayed and moved at the same time. When finding the image to be observed, the operator inputs a scroll stop instruction from an input device such as a keyboard.

[0006]

However, the object that the operator watches while scrolling is an image,
(For example, in a medical image database system,
It is necessary to select an image to be interpreted. In this case, it is said that the graphic displayed along with the movement of the image during scrolling is often disturbed (gaze of the image). There was an inconvenience.
Further, for example, even if there is a display that the user does not want to move in the graphic, such as a title or a top display, there is a disadvantage that the image moves together with the image when scrolled.

The present invention has been made in view of the above-mentioned inconvenience, and in a scrolling method of a display image for displaying a graphic and an image on the same screen, there is no hindrance to image fixation by graphic display during scrolling. An object of the present invention is to provide an image processing apparatus capable of retaining movement.

According to the first aspect of the present invention, there is provided an image display apparatus for displaying graphics and images on the same screen, wherein a scroll means for scrolling the display screen by a scroll instruction is provided. Graphic erasing means for erasing the graphic during scrolling by the scrolling means, and graphic display mode designating means for selectively designating whether or not to move the redisplayed portion of the graphic after scrolling by the scroll amount. Graphic display control means for redisplaying the graphic based on the designation by the graphic display mode designating means. According to the second aspect of the present invention, in an image display device for displaying a graphic and an image on the same screen, a scroll unit for scrolling the display screen by a scroll instruction, and during scrolling by the scroll unit, A graphic erasing unit for erasing the graphic, and a graphic display for determining and displaying whether to display the graphic after scrolling by moving the scroll amount or not, according to the attribute of the graphic, when displaying the graphic after scrolling is completed. And an image display device comprising a control unit.

[0016]

According to the above arrangement, in the scroll image display method according to the present invention, the graphic erasing means erases the graphic while the scroll screen scrolls the display screen. Specifically, after the displayed graphic is deleted from the screen, the scroll movement amount “S” of the image is calculated, the image is moved by “S” and displayed, and only the image is displayed during scrolling. Then, it tests whether there is an instruction to stop scrolling the image, and if there is an instruction to stop scrolling, tests whether there is an instruction to move and display the graphic,
If there is an instruction to move and display the graphic, the graphic is moved by the amount of "S" and displayed. If there is no instruction to move and display the graphic, the graphic is displayed at the position before erasing the screen.

Next, when the display of the graphic is completed, the scrolling of the image is stopped, and when the display is not completed, the presence or absence of the instruction to stop the scrolling of the image is tested again. If there is no scroll stop instruction, the scroll movement amount "S" of the image is calculated again, the image is moved by "S" and displayed, and only the image is displayed during scrolling. Test for presence.

Further, the image display device of the present invention selectively designates whether or not to move the redisplayed portion of the graphic by the scroll amount after the scroll is completed,
Based on this, the graphic is redisplayed. Specifically, the display unit erases the graphic display portion on the screen based on the instruction of the erasure instructing unit, and the moving amount calculating unit uses the image moving amount “S” based on the image moving instruction amount from the moving amount input unit. The display unit moves and displays the image by the moving amount "S" based on the instruction from the image movement display instruction means, and the scroll stop instruction test means tests whether there is an image scroll stop instruction and scrolls. When detecting the stop instruction, the graphic movement display instruction test means tests the presence / absence of the movement display instruction of the graphic, and when the graphic movement display instruction is detected, the display unit displays the graphic before erasure stored in the graphic storage means. Is displayed at a position corresponding to the movement amount "S", and the graphic movement display instruction test means does not detect the graphic movement display instruction. To display before erasing graphics to the position before erasing the screen.
