Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video display apparatus and a display method particularly suitable for a CRT (Cathode Ray Tube) display of a computer.

[0002]

2. Description of the Related Art In recent years, a multi-scan CRT display device has been used as a CRT display device for a computer. The multi-scan type CRT display device is adapted to cope with different horizontal and vertical frequencies.

That is, display modes for displaying a computer screen include a mode of (800 × 600) pixels and a mode of (102) in addition to a mode of (640 × 480) pixels.
There are various modes such as a 4 × 768 pixel mode and a (1280 × 1024) pixel mode. As described above, when the display mode is different, the horizontal frequency and the vertical frequency are different.

Therefore, a CRT display device for a computer in recent years has a multi-scan configuration, and can correspond to a horizontal frequency of about 30 kHz to about 100 kHz and a vertical frequency of about 50 Hz to about 150 Hz. . When a signal is input from the computer, the horizontal frequency and the vertical frequency are set according to the display mode of the input signal. Therefore, when a multi-scan CRT display device is used,
If the display is within the range of the horizontal frequency and the vertical frequency that can be supported, signals of various display modes can be displayed.

As described above, a multi-scan CRT is used.
In the display device, when the display mode is switched, the horizontal and vertical frequencies are switched accordingly. When the horizontal frequency or the vertical frequency is switched in this way, the position of the screen may move or the aspect ratio of the screen may change. For this reason, in this kind of conventional multi-scan type CRT display device, the user can adjust the position and size of the screen. Then, in order to make it easier for the user to recognize the adjustment state, the adjustment state is displayed on the screen on the screen.

In such a multi-scan CRT display device, there is a CRT display device in which various setting items are displayed in a menu on the display screen, and the setting items can be selected from the menu. As such a menu display,
As shown in FIG. 8, a configuration in which setting items are sequentially arranged on each line is known.

However, in the case of the format in which the setting items are arranged in order on each line, it becomes difficult to grasp the setting items at a glance as the number of setting items increases.

Further, as shown in FIG. 9, there is a type in which each setting item is two-dimensionally arranged. As described above, when the setting items are two-dimensionally arranged, the setting items can be easily understood at a glance.

In the case of a menu in which the setting items are two-dimensional, it is necessary to move the pointer in the vertical and horizontal directions in order to select the setting item. For this reason, conventionally, an up arrow key, a down arrow key, a left arrow key, and a right arrow key are prepared, and the pointer is moved using these keys. .

Conventionally, when the down arrow key is pressed, the pointer is moved on the same column from the upper item display to the lower item display, and when the up arrow key is pressed, the pointer is moved. When the right arrow key is pressed from the lower item display to the upper item display and the right arrow key is pressed, the pointer is moved on the same line from the left item display to the right item display. When the left arrow key is pressed, the pointer is moved on the same line from the right item display to the left item display.

Conventionally, when the pointer is moved to the item display at the end in each direction, the movement limit is reached, and even if the arrow key is further pressed, the pointer remains at the same position or the same line is displayed. Or returned to the beginning of the column.

That is, when the down arrow key is pressed, when the pointer is moved to the lowermost display item,
The pointer remains stopped when the down arrow key is kept pressed, or the display returns to the topmost item display in the column. When the up arrow key is pressed, if the pointer is moved to the topmost display item, the pointer remains stopped even if the up arrow key is kept pressed, or the bottom end of the column. Is returned to the item display. When the right arrow key is pressed, if the pointer is moved to the rightmost display item, the pointer remains stopped even if the right arrow key is kept pressed, or the leftmost end of the line. Is returned to the item display. When the left arrow key is pressed, if the pointer is moved to the leftmost display item, the pointer remains stopped even if the left arrow key is kept pressed, or the rightmost end of the line. Is returned to the item display.

[0013]

As described above, conventionally, when the pointer is moved on the two-dimensionally arranged item display, the pointer moves on the same row in the horizontal direction and the same column in the vertical direction. When moving up and the pointer is moved to the end item display in each direction, that becomes the movement limit,
When the arrow key is pressed any further, the pointer remains at the same position or returns to the first position in the same row or column. Therefore, it is impossible to select all items on the two-dimensional array with one key.

For example, it is assumed that the pointer is at the position of the item display P15 as shown in FIG. 10A. And
Assume that the user wants to select the item display P19. In this case, as shown in FIG. 10B, first, the pointer is moved to the position of the item display P16 with the down arrow key, and then the pointer is moved to the position of the item display P19 with the right arrow key. Alternatively, the pointer must be moved to the position of the item display P18 with the right arrow key, and then moved to the position of the item display P19 with the down arrow key. You have to operate the arrow keys.

When the up, down, left, and right direction keys are arranged in a cross shape, it is relatively easy to operate a plurality of keys, but when the up, down, left, and right direction keys are arranged at independent positions. It is difficult to operate multiple keys.

Therefore, an object of the present invention is to select an item display from a plurality of item displays arranged two-dimensionally.
It is an object of the present invention to provide a display device and a display method in which a desired item display can be easily selected using one key.

[0017]

SUMMARY OF THE INVENTION According to the present invention, there is provided a display signal generating means for displaying a menu in which a plurality of item displays are two-dimensionally arranged on a screen, and a display signal generating means for determining a selection target among the item displays. And a movement key for moving the selection pointer between the two-dimensionally arranged item displays.
It consists of a vertical movement key and a horizontal movement key,
When the vertical movement key is operated, the selection pointer is moved along the item display in the same column vertically arranged, and when the selection pointer is moved to the item display at the end of the column, the item at the start end of the next column is moved The selection pointer moves to the display,

1 to P9 can be selected.

Normally, when selecting a two-dimensionally arranged item display, it is necessary to operate a horizontal movement key and a vertical movement key. However, in particular, as shown in FIG. 2, in the CRT display device 1 to which the present invention is applied, the arrow keys 7A to 7D are located at independent positions. When the arrow keys are at independent positions as described above, it is not easy to operate a plurality of keys. In this example, any of the arrow keys 7A to 7D can be used to select one of the desired item displays P1 to P9 from the menu screen. Therefore, all the items arranged two-dimensionally can be selected by a simple key operation.

FIG. 7 is a flowchart showing a process for moving the item display. First, steps S1 to S4
Is used to determine which key has been pressed. That is, it is determined whether or not the up arrow key 7B has been pressed in step S1, whether or not the down arrow key 7A has been pressed in step S2, and whether or not the left arrow key 7C has been pressed in step S3. It is determined whether the right arrow key 7D has been pressed in step S4.

If it is determined in step S1 that the up arrow key 7B has been pressed, the display number is reduced by "1" (step S5). Then, it is determined whether or not the display number is smaller than "0" (step S6). Display number is "0"
If it is smaller, the display number is set to "8" (step S7).

If it is determined in step S2 that the down arrow key 7A has been pressed, the display number is incremented by "1" (step S8). Then, it is determined whether or not the display number is larger than "8" (step S9). If the display number is larger than 8, the display number is set to 0 (step S1).
0).

If it is determined in step S3 that the left arrow key 7C has been pressed, it is determined whether or not the display number is greater than 2 (step S11). If the display number is larger than "2", "3" is subtracted from the display number (step S).
12). When it is determined that the display number is not larger than “2”, it is determined whether the display number is “0” (step S13). If the display number is "0", the display number is set to "8" (step S14). If the display number is not "0", "5" is added to the display number (step S15).

If it is determined in step S4 that the right arrow key 7D has been pressed, it is determined whether the display number is smaller than "6" (step S16). If the display number is smaller than "6", "3" is added to the display number (step S17). If it is determined that the display number is not smaller than 6, it is determined whether or not the display number is "8" (step S19. If the display number is "8", the display number is changed to "0"). If the display number is not 8, "5" is subtracted from the display number (step S15).

When the display number is obtained in steps S1 to S20, the X coordinate is obtained from the value obtained by dividing the display number by "3" (step S21), and the Y coordinate is obtained from the remainder obtained by dividing the display number by 3. The coordinates are obtained (step S2
2). Then, the pointer is arranged at that position and the menu is displayed (step S23).

In the above example, C for the computer is used.
Although the menu display for setting various operation states in the RT display device has been described, the present invention provides two-dimensional operation setting states of various devices such as a television receiver and a satellite broadcast tuner in addition to the CRT display device. This is applicable when operating with the array menu.
