Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a configuration block diagram showing an embodiment of the present invention. In this embodiment, the display device 10
Is connected to the external control unit 11 of the host device by a signal line a, and is mainly composed of an external interface unit 12, a display unit control unit 13, a blink determination unit 14, a blink mode storage unit 15, and a display unit 16. There is.

In this display device 10, when an input signal from the external control unit 11 is input to the display unit control unit 13 via the external interface unit 12 connected by the signal line a, this input signal is moved to the cursor. The blinking determination unit 14 determines whether the signal is a signal related to blinking of a part or a signal of general information such as characters and figures. Here, if it is determined that the signal is related to the cursor portion and the signal is related to blinking, the cursor portion is set on the display 16 composed of a CRT or LCD in the blinking mode which is preset and stored in the blinking mode storage unit 15. If it is not, information corresponding to the input signal is displayed.

Here, the changeable parameters preset and stored in the blinking mode storage section 15 include:
In the present embodiment, there are changes in the display ground color of the cursor portion, movement of the blinking area, reduction of the blinking area area (fixed area), and change of the blinking area area. Changing the parameters changes the cursor portion as follows.

(1) When the background color of the cursor portion is changed: As shown in FIG. 2, the blinking area B has three or more designated colors, and in the present embodiment, the colors A, B, and C. The colors are displayed so as to change cyclically (in the order of numbers 1, 2, 3, 1, ... In the figure). In this case, it is possible to reduce the visual stimulus of the operator or the observer by changing the color periodically.

(2) When moving the blinking area of the cursor portion is changed: As shown in FIG. 3, the blinking portion (hatched portion in the figure) is displayed in pixel units in the blinking area B. And in a discontinuous state to give a cyclical change (in the order of numbers 1, 2, 1, ... In the figure), or in a striped continuous state as shown in FIG. Periodically (numbers 1, 2, 3, 4, 5, 6, 7, in the figure
(8, 9, 10, 1, 2, ...) are displayed with changes. In this case, the number of blinking pixels is reduced as a result, so that the visual stimulation of the operator or the observer can be suppressed.

(3) When the blinking area area of the cursor portion is changed (fixed area) is changed: As shown in FIG. 5, the blinking portion (hatched portion in the figure) is set to the blinking area B. In the above, the blinking area area is periodically reduced at a fixed ratio such as 75%, 50%, and 25%, and the area is fixed and displayed. In this case, since the number of blinking pixels is reduced, it is possible to suppress the visual stimulation of the operator and the observer.

(4) When the change of the blinking area of the cursor portion is changed: As shown in FIG. 6, the blinking portion (hatched portion in the figure) is displayed in the blinking area B, for example. 100% -60% -30% -60% -10
It is displayed by changing the area of the blinking portion to 0% in order in pixel units (in the order of numbers 1, 2, 3, 2, 1, 2, ... In the drawing). In this case, the number of blinking pixels is reduced as a result, so that the visual stimulation of the operator or the observer can be suppressed.

The parameters can be changed by the external control unit 1.
There are a method of selecting from several change patterns defined on the first side and a method of freely setting by the operator each time. FIG. 7 is a flowchart showing the processing procedure of the display signal when selecting from the change patterns defined on the external control unit 11 side. The operation of the configuration shown in FIG. 1 will be described with reference to the flowchart of FIG. 7. First, an input signal from the external control unit 11 passes through the signal line a and is input to the display control unit 13 via the external interface unit 12. Then (step S1), the blinking determination unit 14 determines whether or not the input signal is blinking of the cursor portion (step S2). If it is determined that the cursor portion is blinking, then the type of the parameter is determined. If it is the display ground color change parameter of the cursor portion, it is set in steps S3 and S4, and if it is the blinking area movement parameter. Is set in steps S5 and S6, and in step S7 and step S8 if it is a blinking area area reduction (fixed area) parameter, and in steps S9 and S10 if it is a blinking area area change parameter. The new flashing mode thus set is stored in the flashing mode storage unit 15 (step S11), and thereafter, the flashing mode storage unit 15 is stored.
The display 16 is blinked in the blinking mode stored in step S12.

FIG. 8 is a flow chart showing a setting processing procedure in the case where the operator freely sets each time. In this setting process, when the operator gives an instruction for blinking display resetting together with a parameter to change through a keyboard on the side of the external control unit 11 (step S21), it is determined whether or not this input signal is blinking in the cursor portion. The determination is made by the unit 14 (step S22). Next, the blink determination unit 14
Then, the type of the parameter is determined, and if it is a display ground color change parameter of the cursor part, it is set in steps S23 and S24, and if it is a blinking area movement parameter, in step S25 and step S26, the blinking area area reduction (area If it is a fixed parameter, step S
27 and step S28, if it is a blinking area area change parameter, it is set in step S29 and step S30, respectively. The new blinking mode thus set is stored in the blinking mode storage unit 15 (step S3).
1) and thereafter, blinking is displayed on the display 16 in the blinking mode stored in the blinking mode storage unit 15 (step S32),
Blinking display Reset is complete.

[0017]

As described above, according to the present invention,
Since the blinking is changed to a mode in which the operator's eyes are lightly stimulated according to the operator's request or fixedly, the operator or the observer is caused to pay sufficient attention in normal work, In addition, it is possible to expect an effect that a display device that is easier on the eyes of the operator or the observer can be obtained.
