DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waveform display device which displays a waveform and displays a pop-up window, and more particularly to a waveform display device which allows a pop-up window to be viewed without hiding the waveform.

[0002]

2. Description of the Related Art A waveform display device is, for example, a digital oscilloscope that measures an object to be measured and displays a waveform. FIG. 5 is a diagram showing a display example of a conventional waveform display device.

As shown in FIG. 1, various parameters are set and a waveform a is displayed. Then, when changing the trigger setting or the like, the pop-up menu window b is started to change the setting such as the trigger setting. Thereby, the display of the waveform a changes.

[0004]

In such a device,
Since the waveform a is hidden in the pop-up menu window b, the setting must be changed in the pop-up menu window b and the pop-up menu window b must be closed in order to confirm whether or not a desired waveform a is obtained. If the desired waveform a has not been obtained, the pop-up menu window b is activated again to change the setting, the pop-up menu window b is closed, and the waveform a is checked. Since such an operation has to be repeated, there is a problem that it takes time to confirm whether the setting is good.

It is an object of the present invention to realize a waveform display device that allows a pop-up window to be viewed without hiding the waveform.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram showing one embodiment of the present invention. In the figure, a measurement circuit 1 measures an object to be measured (not shown). The waveform memory (storage unit) 2 stores the waveform data measured by the measurement circuit 1. Text memory (storage)
Reference numeral 3 stores text data (display position information, character information (characters, attributes)). Attributes are information that accompanies a character, such as foreground color, background color,
This is information such as the upper line. For example, the character data is composed of 8 × 16 dots, and the character portion of “A” is displayed in the foreground color, and the others are displayed in the background color.

The display means 4 displays the waveform data of the waveform memory 2 on the display 5, displays a pop-up menu window using the text data of the text memory 3, and displays the display in a semi-transparent manner in the pop-up menu window. 5 is displayed. Then, the display unit 4 also sets the measurement circuit 1. The operation unit 6 is, for example, an operation button,
The display means 4 is controlled.

The display means 4 comprises a semi-transmissive range means 4
1, a position determining means 42 and a priority determining means 43. The semi-transmissive range means 41 determines the semi-transmissive range based on the waveform display range, the display position information of the text memory 3, and the display range of the pop-up menu window. The position determining means 42 determines a dot position to be drawn. The priority determining unit 43 determines the display priority based on the semi-transmissive range of the semi-transmissive range unit 41, the dot position of the position determining unit 42, and the character information of the text memory 3.

The operation of such a device is described below.
FIG. 2 is a flowchart showing the operation of the apparatus shown in FIG.

The semi-transmissive range means 41 determines the semi-transmissive range based on the waveform display range, the display position information of the text memory 3, and the display range of the pop-up menu window (for example, 80 × 30 squares). And the position determining means 4
2 determines the dot position to be drawn on the display 5.

The priority determining unit 43 determines whether the mode is the translucent mode (S1). If the mode is not the semi-transmissive mode, normal display is performed (S5). In the case of the semi-transmissive mode, it is determined based on the semi-transmissive range by the semi-transmissive range means 41 and the dot position of the position judging means 42 whether or not it is in the semi-transmissive range (S
2). If it is out of the semi-transmission range, normal display is performed (S
5). If it is within the semi-transmissive range, it is determined whether the dot is the background of the pop-up menu window (S3). If it is not the background, a foreground (character dot) is displayed (S8). In the case of the background, whether the dot position is an even line and an even raster,
It is determined whether an odd line is an odd raster (S4). If neither is the case, a background color dot is displayed (S7). If so, waveform dot display is performed (S6).

It is determined whether or not the process has been completed for all dot positions (S9). If the processing has been completed, the processing is completed. If not, the processing returns to the beginning of the processing again to determine whether or not the mode is the translucent mode (S1).

When all the processes are completed, FIG.
Is displayed. That is, the waveform a can be seen through the pop-up menu window b. More specifically, the waveform a and the pop-up menu window b shown in FIG.

Then, the menu of the pop-up menu window b is operated by the operation unit 6. Display means 4
Performs settings made by the operation unit 6 on the measurement circuit 1. The measurement circuit 1 stores the measurement result in the waveform memory 2 as waveform data. This waveform data is displayed on display means 4
Is displayed on the display 5.

As described above, the display means 4 is provided with the waveform memory 2
Since the waveform is displayed semi-transparently in the pop-up menu window b based on the character information in the text memory 3, the waveform is not hidden by the pop-up menu window b. Also, since the waveform is displayed translucently, the contents of the pop-up menu window b can be clearly displayed, and
The waveform can be confirmed.

Since all the foregrounds of the characters are displayed, the characters can be easily read.

Further, since the pop-up window is a pop-up menu, setting and the like can be changed while checking the waveform.

The present invention is not limited to this, but may be as follows. An example of a popup window with a popup menu is shown.
For example, a configuration such as "cannot be set in this mode" may be displayed.

The waveform memory 2 and the text memory 3
May be one memory. And the text memory 3
May store the display position information and the character information in separate memories.

The display position information is stored in the text memory 3.
Has been described, but the configuration held by the display means 4 may be used.

[0023]

According to the present invention, the following effects can be obtained. According to the first to third aspects, the display means displays the waveform semi-transparently in the popup window, so that the waveform is not hidden by the popup window. Also, since the waveform is displayed translucently, the contents of the pop-up window can be clearly displayed and the waveform can be confirmed.

According to the fourth aspect, since all the foregrounds of the characters are displayed, the characters can be easily read.

According to the fifth aspect, since the pop-up window is a pop-up menu, it is possible to change settings and the like while checking the waveform.
