Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device applied to, for example, a display device of a computer.

[0002]

2. Description of the Related Art In an electronic device having an image display function, for example, a display device of a computer, for example, the size of a screen (raster) displayed by underscan, the center position of the screen (raster), and the influence of geomagnetism. It is designed so that the user can arbitrarily adjust elements related to image display such as rotational distortion of the screen, pincushion distortion, convergence, brightness, and contrast.

When performing such adjustment, in recent years, for example, the adjustment is performed by digital processing using operation keys for controlling the increase and decrease of the adjustment amount. Therefore, when such adjustment is performed, a display indicating the adjusted amount is displayed on the screen of the video display function so that the user can confirm the adjusted amount by this display.

That is, for example, in FIG. 5, it is assumed that time elapses from the top to the bottom of the drawing. Then, for example, as shown on the left side of the figure, the state of the operation key is sequentially changed from the state of “not pressed” to the state of “pressed” and the state of “released”, and the value of the adjustment data is changed to “35” accordingly. →
If it is changed from "36" to "37", the position of the displayed data bar is sequentially changed, as shown in the right side of the figure.

Thus, the user can confirm the amount of adjustment made by operating the operation keys by the position of the data bar displayed on the screen. Then, the adjustment can be performed favorably and smoothly by performing the adjustment while confirming the position of this display.

[0006]

However, in the display of such an adjustment amount, the display accuracy is limited by the number of pixels of the screen forming the display. For this reason, for example, when trying to display adjustment data with a large amount of change in a relatively small display range, the number of display change steps becomes smaller than the number of adjustment data change steps. The display may not change even if the data changes.

That is, for example, in FIG. 6, it is assumed that the display is changed by one step with respect to the change of the adjustment data by three steps. Then, as with the above, there is a passage of time from the top to the bottom of the drawing, and for example, the state of the operation keys is "not pressed", "pressed", "released" as shown on the left side of the drawing. It is assumed that the value of the adjustment data is changed to “35” → “36” → “37” accordingly.

Then, in this case, the position of the displayed data bar is not reflected in the display even if the value of the adjustment data is changed by two steps. For example, as shown on the right side of the figure, the display remains unchanged. Become. For this reason, the user cannot confirm whether or not the adjustment has been actually performed by operating the key, which may give the user an uncomfortable feeling.

This application has been made in view of such a point, and the problem to be solved is that in the conventional apparatus, the number of stages of change of the adjustment data is different from the number of stages of change of the display. When the number of is small, when the user operates the key,
In some cases, it may not be possible to confirm whether or not the operation has been effectively performed, which may give the user an uncomfortable feeling.

[0010]

Therefore, in the present invention, a display indicating that the adjustment data is being adjusted is provided in the display. It is clearly shown to be effective, and it is possible to eliminate anxiety when the user makes adjustments.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION That is, according to the present invention, in an electronic device having a video display function, the adjustment data of any adjustable element is displayed on the screen of the video display function and the adjustment data is adjusted in the display. It is provided with means for displaying that it is inside. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an example of a display device of a computer to which an electronic device according to the present invention is applied.

In FIG. 1, a keyboard 1 including the above-mentioned operation keys and the like is provided, and input data from the keyboard 1 is supplied to a microcomputer 2 for controlling and adjusting the entire apparatus. Further, a storage device 3 including a non-volatile memory capable of storing data even when the power is turned off is provided, and the storage data from the storage device 3 is transferred to the microcomputer 2 through the bus line 4.
Supplied to

Further, a video circuit 5 to which an arbitrary video signal (R / G / B) is supplied is provided, and the adjustment in the video circuit 5 is performed through the bus line 6 by the above-mentioned microcomputer 2, for example. Further, an OSD circuit 7 for performing a video display function (OSD) is provided, and the formation of display by the OSD circuit 7 is controlled by the microcomputer 2 through the bus line 6.

Further, the display signal (R / G / B) formed by the OSD circuit 7 is supplied to the video circuit 5. Then, the composite signal (R / G / B) from the video circuit 5 is supplied to the image display device 8 including a cathode ray tube (CRT). As a result, a display screen on which the display formed by the OSD circuit 7 is superimposed is formed on the image of the video signal (R / G / B) supplied to the video circuit 5 described above.

In this device, the above OSD circuit 7 forms a display as shown in FIG. 2, for example.
That is, in FIG. 2, left and right arrow marks 71 and 72, which are the same as the marks provided on the operation keys, are provided at both ends of the display.
Is provided to indicate the direction of adjustment. Then, a data bar 73 showing the adjustment amount is displayed between the marks 71 and 72. Therefore, for example, when an arbitrary adjustment is made by the operation key of the keyboard 1, the position of the data bar 73 displayed is changed according to the adjustment amount.

Further, in FIG. 2, it is assumed that time elapses from the top to the bottom of the drawing. Then, for example, as shown on the left side of the figure, the state of the operation key is sequentially changed from the state of “not pressed” to the state of “pressed” and the state of “released”, and the value of the adjustment data is changed to “35” accordingly. "→" 36 "
→ It is assumed that the change is made to "37" → "38".

Then, in this case, for example, the data bar 73
The displayed position is as shown on the right side of the figure.
It is changed only when it is changed from 7 ”to“ 38 ”. Along with that, during the period when the operation key shown on the left side is in the "press" state, the same mark as the pressed operation key, for example, the right arrow mark when the right arrow operation key is pressed The display of 72 is blinked, and the so-called blink display is set.

This allows the user to confirm the amount of adjustment made by operating the operation keys by the position of the data bar 73 displayed on the screen, and
The state of the operated key is indicated by the left and right arrow marks 71, 7
It can be known by the change of 2. Then, the adjustment can be performed favorably and smoothly by making the adjustment while checking these displays.

That is, in this apparatus, when the adjustment amount is increased or decreased by using the operation keys of the keyboard 1, for example, a signal is supplied from the microcomputer 2 to each part such as the video circuit 5 according to this control, and various signals in digital processing are supplied. Adjustments are made. Then, a display indicating the adjusted amount is formed by the OSD circuit 7, and this display is performed on the screen of the video display device 8.

At the same time, in this display, the operating state of the operation key and the direction of the operation can be known by the change of the left and right arrow marks 71 and 72. Therefore, the user can confirm that the adjustment is in progress and the direction of the adjustment by looking at the display of the arrow marks 71 and 72, and the desired adjustment can be satisfactorily performed.

Further, FIGS. 3 and 4 show an example of a flowchart for performing the operation of the above-mentioned apparatus. That is, in this example, the display color of the normal arrow other than when the keyboard 1 is being operated is color 1, and the arrow alternates between color 1 and color 2 when blinking. Also, "arrow flag" in the figure
Indicates the color of the arrow, and the variable tm counts the blinking cycle.

Therefore, FIG. 3 shows a process of switching the "arrow flag" to the color 1 or the color 2 at regular intervals corresponding to the operation of the keyboard 1. In FIG. 3, the keyboard 1 is taken in at a constant cycle, and it is determined in step S1 whether or not the data adjustment key is pressed.

When the data adjustment key is pressed (Y
es) determines whether or not the variable tm = 0 in step S2. Further, when the variable tm = 0 (Yes), the “arrow flag” is set to color 1 in step S3, and step S3 is executed.
In step 4, the [flicker cycle] is set to the variable tm. Then, in step S5, tm-1 is substituted for the variable tm, and the process is temporarily terminated.

When the variable tm = 0 is not satisfied in step S2 (No), it is determined in step S6 whether or not the variable tm is [half the blinking cycle]. When the variable tm = [half of blinking period] (Yes), the "arrow flag" is set to color 2 in step S7, and the process proceeds to step S4. If the variable tm is not equal to [half the blinking period] in step S6 (No), the process proceeds to step S5 as it is, tm-1 is substituted into the variable tm, and the process is temporarily terminated.

If the data adjustment key is not pressed in step S1 (No), it is determined in step S8 whether or not it is immediately after the adjustment key is released. Immediately after the key is released (Yes), the "arrow flag" is returned to color 1 in step S9, the variable tm is set to [half the blinking cycle] in step S10, and the process is terminated. If it is not immediately after the adjustment key is released in step S8 (No), the process ends.

As a result, the "arrow flag" is normally set to color 1 and the variable tm = [half the blinking period].
When the microcomputer 2 detects that the user has pressed the data adjustment key of the keyboard 1 to perform the adjustment, the arrow indicating the control direction is changed to the color 2 by the steps S1 → S2 → S6 → S7, and the variable tm = ( [Half the blinking cycle] -1) and the process ends.

Therefore, when step S1 is executed next, tm ≠ 0, and tm ≠ [half the blinking cycle],
Only step S5 is executed. And further tm = 0
Then, the "arrow flag" is returned to the color 1 by the steps S1 → S2 → S3 → S4 → S5, the variable tm = ([flashing cycle] −1) is set, and the process is terminated.

This operation is repeated until the user releases the data adjustment key of the keyboard 1. As a result, the "arrow flag" is alternately switched to color 1 or color 2 in the above-mentioned [flashing cycle]. When the key is released further, step S1
→ S8 → S9 → S10, the “arrow flag” is returned to color 1, the variable tm is set to [half of the blinking cycle], and the process is terminated.

Further, FIG. 4 shows a main part of a preparation program for transmitting display data to the OSD circuit 7. That is, in FIG. 4, first, in step S11, it is determined whether or not the line to be transmitted next to the OSD circuit 7 is the row of the arrow.

When the next transmission is in the row of arrows (Yes), the setting of the "arrow flag" is determined in step S12, and when the color is 1, the OSD circuit 7 is set in step S13.
The display data of the arrow is set to color 1 and the process ends.
If the setting is color 2 in step S12, step S1
In step 4, the display data of the arrow is set to color 2 in the OSD circuit 7, and the process is ended.

If the next transmission is not the row indicated by the arrow in step S11 (No), it is determined in step S15 whether the next transmission to the OSD circuit 7 is the row of the data bar. If it is the row of the data bar (Yes), the position of the bar is set so as to correspond to the value of the table of the current adjustment data in step S16, and the process is ended. If the line is not the data bar (No) in step S16, the process ends.

As a result, in this program, when the display data of the row of the arrow is prepared, the actual O value is set according to the "arrow flag" set in the flow chart of FIG.
By setting the bit determining the color of the character of the display data transmitted to the SD circuit 7 in step S13 or S14, the color of the arrow marks 71, 72 of the display formed by the OSD circuit 7 is changed.

Further, when preparing the display data of the row of the data bar, the display position of the data bar is updated based on the value of the adjustment data table. As a result, when the user changes the adjustment data using the keyboard 1 or the like, the display position of the data bar is changed to the position corresponding to that data.

Therefore, in this device, it is possible to display in the display that the adjustment data is being adjusted. As a result, conventionally, if the number of change stages of the display is smaller than the number of change stages of the adjustment data, it may become impossible for the user to confirm whether or not the operation has been performed effectively, and the user may not be able to confirm. According to the present invention, it is clarified that the operation of the key is effective, and it is possible to eliminate the anxiety when the user makes an adjustment, which may give unnecessary anxiety.

Further, by performing the display indicating that the adjustment is being performed, for example, by blinking the same arrow mark as the operation keys provided at both ends of the display of the adjustment data, the user can confirm the effectiveness of the key operation. The direction of the adjustment can be easily confirmed, and the desired adjustment can be satisfactorily performed.

Thus, according to the electronic device described above, in the electronic device having the video display function, the adjustment data of any adjustable element is displayed on the screen of the video display function, and the adjustment data is adjusted in the display. By providing the means for displaying the inside, it is possible to clearly show that the key operation is effective, and it is possible to eliminate the anxiety when the user makes the adjustment.
