Description

[Detailed explanation of the invention] <Industrial application field> This invention is suitable for measuring measurement results such as spectrophotometers, colorimeter, spectrum analyzers, FFT analyzers, digital oscilloscopes, etc.
This invention relates to a measuring instrument with a two-dimensional display device that displays diagrammatically on a two-dimensional display device such as a CRT or liquid crystal panel.

<Prior art> Generally, in a measuring instrument with a two-dimensional display device, the fifth
As shown in the figure, the measurement results are displayed as a graph, and additional information such as measurement parameters and messages instructing the next operation may be displayed. Conventionally, such additional information has been displayed at a predetermined position at the bottom of the screen.

<Problems that the invention aims to solve> However, with this, a part of the screen is occupied to display the additional information, which reduces the space available for displaying the measurement results as a graph. Since the space for displaying information is fixed, there is a problem in that the amount of additional information that can be displayed is limited.

<Means for solving the problem> Generally, when displaying measurement results in a graph or the like, it is easier to see and understand if the entire screen is used to display the results, as shown in FIG. At this time, graphs and the like are rarely drawn on the entire screen, and in most cases there is a blank space in a part of the screen. This idea attempts to display additional information in this blank space.

Therefore, this invention has an image memory 2 as shown in FIG. The image memory 2 stores digital display data for displaying measurement results on the two-dimensional display device 4 in correspondence with the screen of the two-dimensional display device 4. This invention also includes additional information determining means 6 for determining information to additionally display characters such as letters, numbers, and codes on the screen.
This additional information is supplied to readout position determining means 8, which determines the screen area required to display this additional information, and also provides addresses for reading out this screen area at various positions in the image memory. Generate a signal. In accordance with this address signal, the reading means 10 reads out screen areas at various positions in the image memory 2. The determining means 12 determines whether digital display data exists in each screen area read out at various positions in this manner. The writing means 14 writes additional information in the screen area where the determining means 12 determines that no digital display data exists. Therefore, according to this invention, additional information can be displayed in a blank area of the screen.

<Example> This example is configured as shown in FIG. is memorized. Further, the display controller 24 reads out the stored values in the image memory 20 and displays them on the two-dimensional display device 26 according to instructions from the central processing unit 18 . The image memory 20 has a total of X and Y addresses, X in the horizontal direction and Y in the vertical direction, and each of these addresses corresponds to each position on the screen of the two-dimensional display device 26. For example, When displaying a curve as shown in FIG. 4, "1" is stored in each address of the image memory corresponding to the position where this curve passes on the screen, and "0" is stored in the other addresses.

Next, the operation of this embodiment will be explained with reference to FIG. Furthermore, as mentioned above, the image memory 2
0 already has "1" or "0" to display the curve
Suppose that data is stored.

In this state, first, necessary additional information is determined from the measurement results (step A). Next, the space required to display this additional information is calculated (Step B). By calculating this space, the horizontal distance (the number of addresses in the horizontal direction) X and the vertical distance (the number of addresses in the vertical direction) Y necessary for displaying as shown in FIG. 4 can be obtained.

Then, as shown in Fig. 4, four parameters are predetermined to check whether there is a vacancy, namely,
Position on screen (each address of image memory 20)
The first one of X _a , Y _a ; X _{b ,} Y _b ; _{X c , Y c} ; Next, an area to be checked for vacancy is determined based on the set parameters and the calculated space (step D). By this, for example, X _a , Y _a ; X _a +X, Y _a ; X _a , Y _a +Y; X _a +X,
Area 2 whose four corners are the four addresses of Y _a + Y
Determine 8. Then, depending on whether there is even one address storing "1" in this area 28, it is determined whether the determined area is blank (step E). In the case of area 28, since it is not blank as is clear from FIG. 4, this determination is NO, and it is determined whether all scheduled areas have been completed (step F). Since this judgment is NO, the parameters for the next scheduled area, for example, X _b and Y _b are set (step G) and the process returns to step D. As a result, area 30 is determined, and step E
However, in the case of area 30, the result is NO, so step F is executed and this judgment is also made.
Since the answer is NO, step G is executed and parameters X _c and Y _c are set. and step D
Area 32 is determined in step E, and it is determined whether it is blank or not, but since area 32 is also NO, the parameters X _d , Y _d are determined in step G after passing through step F.
is set. Then, in step D, Elijah 3
4 is determined, and in step E it is determined whether it is blank.
In this case, since the answer is YES, additional information is written in area 34 of image memory 20 (step H).
Thereafter, the display controller 24 sequentially reads out the stored values from the image memory 20 using a known method, and the curve and additional information as shown in FIG. 4 are displayed on the screen of the two-dimensional display device 26.

In the above example, four parameters are used,
Although we searched for blank areas, this was done to shorten the time required to search for blank areas.If there is no need to shorten the time, you may increase the number of parameters or set no parameters at all. Alternatively, the entire image memory 20 may be searched.

<Effects> As described above, according to this invention, a blank area of the image memory is searched and additional information is stored in this blank area, so the space for displaying measurement results as a graph becomes narrower. There is no restriction on the amount of additional information displayed.
