Abstract

PURPOSE:To enable an operator to easily perform continuous actions and also to discriminate the set-up time of a parameter from the set-up time of a menu by setting a cursor back to a menu item selected previously after a prescribed task is carried out with a mouse. CONSTITUTION:When a picture processing parameter changing menu is selected by a mouse 1, a cursor disappears and a fact that a parameter can be changed is noticed to an operator. Thus a function of an operator guide is attained. When the operator clicks a mouse button at the time of ending the change of the parameter, the cursor is set back to a menu item that selected a picture processing parameter. Thus it is not required to search for the cursor and set it back to its original position. As a result, the operator can easily have the continuous actions. When a concerned area ROI is selected by the mouse 1, the cursor is set back to a ROI item selected previously. Furthermore an item requiring a picture processing type is selected by the mouse 1, plural types of menu items are displayed. Then the cursor moves to a current processing type, i.e., the default and then returns to a desired menu item.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides an image display device that executes a task according to an item selected from a menu screen using a coordinate input means such as a mouse. Regarding.

(Prior Art) For example, in an image display device that handles medical images, when displaying an image on the display and setting a ROI (region of interest) or changing image processing parameters (hereinafter simply referred to as parameters), it is necessary to Coordinate input devices such as these have been used. In this case, first select any item from among the multiple items on the menu screen displayed on the display by moving the mouse cursor (simply referred to as cursor), and then click the mouse button to select the item. They carry out the work that they have done. For example, when setting an ROI, the user selects the ROI item and then clicks the mouse button to move the cursor within the image.

Furthermore, when changing a parameter, the user selects a desired item, for example GA, and then clicks a mouse button to determine a specific parameter value. When performing such operations, the cursor always moves continuously across the screen, and the cursor is always displayed somewhere on the screen.

(Problems to be Solved by the Invention) However, the following problems exist in conventional image display devices.

(1) When changing parameters, the cursor has moved to the top or right edge of the screen.

(2) Since the cursor is displayed even when changing a parameter, it is difficult to distinguish it from when selecting a menu.

(3) When setting the ROI, the cursor remains inside the image after the ROI is set.

In cases (4), (1), and (3), it is difficult for the operator to take the next action because the location of the cursor is uncertain.

The present invention has been made in response to the above-mentioned problems.
It is an object of the present invention to provide an image display device that can solve various conventional problems.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above object, the present invention provides a method for selecting an arbitrary item from a menu screen displayed on a display by moving a cursor and operating a coordinate input means. In an image display device that executes a job according to each item, a control means has a function of returning the cursor to the selected item when the coordinate input means performs an operation to execute the job according to the selected item. It is characterized by having the following.

(Function) For example, after setting the ROI or changing parameters, the cursor always returns to the previously selected item on the menu screen, making it easier for the operator to take continuous actions even after setting RoT or changing parameters. Furthermore, since the cursor disappears while changing parameters, the operator can distinguish parameter setting from menu selection.

(Example) The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the image display device of the present invention, in which 1 is a mouse that functions as a coordinate input device, which determines the coordinates in the x and y directions on the display screen and moves the cursor to an arbitrary position (mouse cursor). , select any item on the menu screen, and click the mouse button to perform a task according to each selected item. For example, when setting an ROI, select the ROI item, move the cursor within the image by clicking the mouse button, and change the parameters by selecting the desired item and clicking the mouse button. Determine the parameters. Reference numeral 2 denotes an input section, which is composed of a keyboard and is equipped with various switches necessary for inputting image data. 3 is the address when you click the cursor button in the cursor buffer (
This is a memory for storing data (x, y) and reading it as necessary. Reference numeral 4 denotes a display, which is made up of a CRT or the like and is used to display images. Reference numeral 5 denotes a control unit, which is composed of a CPU (central processing unit), has various calculation and control functions, and is in charge of overall control operations.

FIG. 2 is a configuration diagram showing an overview of the apparatus of this embodiment, in which an image 6 is displayed on a screen on a display 4, and a plurality of menu items 7 are also displayed.

Move the cursor 8 to any item by operating the mouse 1
is moved to make a selection, and a black and white inverted cursor 8 is displayed on the selected item.

9 indicates a parameter value.

Below, we will explain how to operate the mouse when performing each task according to the selection item.

1. When changing image processing parameters To take an example of changing GA as a parameter while the screen is displayed as shown in Figure 2, move the cursor 8 to GA and then click the mouse button. . This allows the third
The cursor disappears as shown in figure (a). Next, if you move the mouse 1 to the left or right, for example, if you move it to the left, the parameter value 9 will decrease, and if you move it to the right, the parameter value 9 will increase. When you decide that the parameter value 9 is the desired value, press the mouse button. When clicked, the cursor returns to GA, which is the previously selected item, as shown in FIG. 3(b). Note that when the parameter value 9 is adjusted, the content of the image 6 also changes according to the change in this value.

2. When setting the ROI, move the cursor 8 to the Rot item and click the mouse button as shown in FIG. 4(a). As a result, the cursor 8 is moved inside the image 6 as shown in FIG. 4(b), and the ROI is set as 10 inside the image 6 using the mouse 1.

Next, when the operator clicks the mouse button, the ROI
After the IO setting is completed, the cursor 8 moves from inside the image 6 again to the ROI, which is the preselected item as shown in FIG. 4(a).
come back to.

3. When selecting the image processing type Although this image processing type is a type of parameter,
It is not a numerical value (it means a fixed type such as A, B, or C).

For example, taking GT as an example as shown in Figure 5(a), when the cursor 8 is moved to the GT item, the currently existing processing types A, B, C, and D are displayed as shown in Figure 5(b). Is displayed. Next, if the operator selects A and clicks the mouse button, the image 6 will be processed based on this A type, and at the same time the cursor 8 will be moved again as shown in Fig. 5 (a).
) to return to the preselected item GT.

As described above, according to each operating method of this embodiment, first, the above-mentioned 1.
In this case, when the image processing parameter change (numeric value) menu is selected with the mouse, the cursor disappears, informing the operator that the parameter can be changed, and acting as an operator guide. In addition, when the operator clicks the mouse button when finishing changing parameters, the cursor returns to the menu item where the image processing parameter was selected.
There is no need to search for the cursor and return it to its original position.
This makes it easier for the operator to take continuous actions. Next, in case 2 above, when the ROI is selected with the mouse, the cursor 8 moves to the center of the image 6 and can only be moved within the image 6. Furthermore, after setting the ROI, the process returns to the previously selected Rot item in the same manner as in step 1 above. Furthermore, in case 3 above, when you select an item that requires an image processing type with the mouse, menu items A and B appear.

A plurality of types such as C and D are displayed, and the cursor moves to the default current processing type. Furthermore, after selecting the processing type, the menu returns to the menu item that requires the previously selected image processing type, similar to 1 above.

FIG. 6 is a flowchart showing the algorithm of this embodiment.

First, in step A, an arbitrary menu item is selected, and then in step B, a mouse button is clicked. As a result, in step C, the cursor addresses (x, y) at the time of clicking are stored in the cursor buffers X and Y, respectively. Next, in step D, execution of a task according to the selected menu item, for example ROI
setting.

Parameter changes etc. are performed. Subsequently, in step E, a menu item is selected again, and then in step F, the cursor address (X.

y) from the cursor buffer and returned to the previously selected menu item for display. Then, as in step G, the process waits for a click by the operator.

Operations for executing each of the above tasks are performed based on such an algorithm.

[Effects of the Invention] As described above, according to the present invention, the cursor is returned to a preselected menu item after performing an operation using the mouse to perform a predetermined task. It becomes easier to take actions, and it is possible to distinguish between parameter setting and menu setting.
