BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a structural conceptual diagram showing an example of an apparatus according to the present invention. Here, it is assumed that the apparatus is used for a personal computer or a workstation. In the figure, 1 is a graphic display screen by a liquid crystal screen or a CRT screen, and 2 is a pointing means for pointing a specific point on the display screen such as a mouse with a cursor or the like. As the pointing means, it is possible to use a touch screen outside the mouse, a joystick, a trackball, a keyboard, or the like.

Reference numeral 3 is a graphic image memory, and 4 is an image display means for displaying the graphic image read from the graphic image memory 3 on the graphic display screen 1. Graphic image memory 3
As the graphic image stored in, for example, image data such as a favorite photograph read from an image reader (not shown), graphic image data created by a graphic editor or the like by itself can be used.

Reference numeral 5 designates a specific area setting / registration means for selecting at least one arbitrary specific area in the image displayed on the screen 1.
It has the function of pre-setting and registering at more than one place. This function is performed by, for example, displaying a favorite photograph image on the screen as shown in FIG.
Is moved to an arbitrary place in the image (for example, the position P of the left window of the right tower of the displayed building), and the position (area) of the point P is set and registered.

Designated position detecting means 6 detects a designated position (for example, a cursor position) on the display screen 1 designated by the pointing means 2, and outputs a position signal of a designated place. Reference numeral 7 denotes a determination means, which inputs a position signal output from the designated position detection means 6 and a signal related to the position of the specific area P already stored in the specific area setting registration means 5, and the position signal sets the specific area setting. When the inside of the specific area preset by the registration means 5 is indicated, a key lock release signal is output.

Reference numeral 8 is a control means for controlling the overall operation, which gives an instruction to display an image on the graphic display screen 1, an instruction to detect a designated position, an instruction to enter a setting registration mode or a steady mode. Next, the operation of the apparatus configured as described above will be described separately for the setting registration operation of the specific area and the key lock releasing operation. (Setting registration operation of specific area) Before using the device,
First, it is necessary to perform the setting registration operation of the specific area for releasing the key lock. For this purpose, the operator first instructs the control means 8 to enter the setting registration mode. The control means 8 receives this and causes the image display means 4 to read the graphic image data stored in the memory 3, and displays the graphic image on the graphic display screen 1. Here, it is assumed that the graphic image memory 3 previously stores graphic image data of a favorite photograph, painting, illustration, graphic, etc., and the operator can select and display a favorite graphic image as necessary. Is done.

Subsequently, the operator moves the cursor CR to an arbitrary position (for example, the position P of the left window of the right tower of the displayed building) in the displayed graphic image, and moves the position of the point P. Specify (Area). Here, when a touch screen or the like is used as the pointing means 2, it is difficult to specify only one dot on the screen on which the image is displayed, so a plurality of dots are specified as one block.

The specific area setting registration means 7 stores the specific area position P, which has been set and registered, as a coordinate position signal, for example. Once such a setting registration operation is performed, the subsequent operations will not be able to enter the setting registration mode or operate the device unless the operation for unlocking the key described below is performed. There is. This makes it impossible to arbitrarily change the specific area in the subsequent operations.

In the setting registration of the specific area, the place to be selected as the specific area may be any position of the graphic image, and the number of selected positions is enormous depending on the contents of the displayed image. It's not easy to spot. However, it is necessary for the operator to memorize the specific area that has been set and registered, so it is easy to memorize it in relation to the displayed graphic image (for example, the door window of the left house or the third one from the right). Like the root of a tree)
It is desirable to select.

(Key Lock Release Operation) When the power of the device is turned on, the graphic image which is the target of setting the specific area in the setting registration mode is displayed on the graphic screen 1. Here, in the displayed graphic image, the operator who already knows the location of the specific area operates the pointing means 2 to move and specify the cursor CR to the specific area.

The position designated by the pointing means 2 is detected by the designated position detecting means 6. The determination means 7 includes a position signal output from the designated position detection means 6,
A signal related to the position of the specific area position P registered and set which is stored in the specific area setting / registering means 5 is inputted,
It is determined whether the position signal matches or is close to the specific area position P.

As a result of the judgment, the position signal is the specific area position P.
If it is in the vicinity of the range that matches or is allowed, the key lock release signal is output. On the other hand, when the position designated by the operator is not in the specific area, the key lock state is maintained. As a result, only the operator who knows the location of the specific area can unlock the key and maintain high security.

Here, the key lock release signal is output to the control means 8 and other circuits (not shown) to be used as a start signal of the apparatus or for the next screen development,
It is also used for access permission to the database.
In the operation for releasing the key lock, the control means 8
It has a function of counting the number of times that the position designated by the operator is judged by the judging means 7 not to be within the specific area. When the number reaches a predetermined number (for example, three times), the key lock releasing operation thereafter is stopped or not accepted for a certain time (for example, two hours). This makes it possible to prevent an act of trying to find the specific area by a plurality of operations.

In the embodiment of FIG. 1, the specific area is set and registered in one place, but two or more specific areas are set and registered in advance in order to perform the key lock releasing operation. In the case where the operator designates the specific area according to a predetermined order,
The key lock release signal may be output.

FIG. 2 is a block diagram showing the configuration of another embodiment of the present invention. In this embodiment, the screen display means 4 is provided with a screen switching means 41 for sequentially switching the different graphic images on the graphic display screen 1 to display the screen, and the judging means 7 detects the designated position on the previously registered specific screen. When the position signal output from the means 6 indicates the inside of the specific area preset by the specific area setting registration means 5, the key lock release signal is output. Here, the display screens are switched by first displaying a plurality of images 1 to n in an overlapping manner on the first screen, or reducing and arranging them side by side, and selecting from them. The configuration is such that it is selected by designating the screen.

Higher security can be maintained by a combination of selecting a specific one of a plurality of graphic images and designating a specific area. In this embodiment, a specific area is set and registered in each of a plurality of selected graphic images, and the determination means 7 is output from the designated position detection means 6 on a plurality of screens that are switched and displayed. The key lock release signal may be output when the position signal indicating each of the specific areas preset by the specific area setting / registering means 5 is output.

FIG. 3 is a block diagram showing the configuration of another embodiment of the present invention. In this embodiment, a soft key display means 42 for displaying a plurality of soft keys S1 to Sn together with a graphic image is provided in the graphic display screen 1 in the embodiment of FIG. A position signal to be output is input, and the position signal indicates the inside of the specific area preset by the specific area setting registration means 5, and is preset and registered in the plurality of soft keys S1 to Sn. The configuration is such that a key lock release signal is output when one soft key is designated. Here, a function as an execution key or an entry key may be assigned to one set and registered soft key.

According to this embodiment, high security can be realized by a combination of designation of a specific area and selection of a soft key. In the above description, it is assumed that one type of image is displayed on the display screen, but multiple images are displayed in parallel in a multi-window format, and a specific area is set for each graphic image. You may make it register. Further, the operations described in each embodiment may be combined.

[0024]

As described above in detail, according to the present invention, a password composed of a combination of numbers and characters is not used, but the password is set and registered at an arbitrary position in the displayed graphic image. The key lock can be released only by the operation of designating the specific area by operating the pointing means (for example, mouse operation). Therefore, it is not necessary to operate a keyboard or the like, and high security can be maintained even though the operation is simple.
