  In such a configuration, the electronic computer 10 has a screen capture function. This is a function for capturing the currently displayed screen data as a captured image, and is activated by operating a “Capture” key 12 f provided in the key input unit 12. This captured image can be used as the background of the screen or can be pasted to electronic teaching material data for learning support. However, when such a captured image is displayed on the screen, the user may be confused because it cannot be visually distinguished from a normal image that can be actually operated by key input.

  Therefore, the present invention is characterized in that a captured image is processed and displayed so as to be distinguishable from a normal image.

A display example of the captured image after the processing will be described later with reference to FIGS.

In addition, the processing of the captured image is performed at any of the following timings.
・ When saving (see Fig. 4)
・ At the time of display (see Fig. 6 and Fig. 8)
・ When setting the background (see Fig. 5)
・ When creating electronic teaching materials (see Figure 7)
Note that the timing at which the processing is performed can be arbitrarily set by the user on a setting screen (not shown) displayed on the display unit 13 by operating the “MENU” key 12 c provided on the key input unit 12. And

  Hereinafter, the processing operation at each timing will be described with reference to a flowchart. Note that the processes shown in the following flowcharts are executed when the CPU 11, which is a computer, reads the display control program 14 a stored in the storage device 14.

(A) Screen capture (saving captured images)
FIG. 4 is a flowchart showing a processing operation related to screen capture executed by the CPU 11 provided in the electronic computer 10.

  Now, some image data is expanded in the display data storage area 15 a of the RAM 15 and displayed on the screen of the display unit 13. In this state, when the user depresses the “Capture” key 12f provided in the key input unit 12 (Yes in Step A11), the screen data currently displayed in the display data storage area 15a of the RAM 15 is displayed on the CPU 11. (Step A12).

  The image data captured by the CPU 11 is given a data name such as “No. 1” (step A13), and is stored as a captured image in the captured image storage area 15d of the RAM 15 (step A15). At this time, when a capture image processing mode is set in advance, a processing process for visually distinguishing the image data from a normal image is performed (step A14).

(B) Background Setting FIG. 5 is a flowchart showing processing operations related to screen setting executed by the CPU 11 provided in the electronic computer 10.

  When the user selects “screen setting” by operating the “MENU” key 12c provided in the key input unit 12 (Yes in step B11), a setup screen (not shown) is displayed on the display unit 13 (step B12).

  In this setup screen, various items relating to screen setting are provided. When the item “graph background” is set (Yes in step B13), image data used as a background when the graph is displayed is selected (step S13). B14), the image data is stored in the second layer layer image storage area 15c of the RAM 15 (step B16). At this time, assuming that the above-described captured image is selected as the background, when the capture image processing mode is set in advance, the above-described processing is performed on the image data (step B15).

(C) Graph display (capture image display 2)
FIG. 6 is a flowchart showing processing operations related to graph display executed by the CPU 11 provided in the electronic computer 10.

  Assume that image data used as a background is already stored in the second layer image storage area 15c of the RAM 15.

  After the user sets the graph mode by operating the “Graph” key 12g provided in the key input unit 12 (Yes in Step C11), the user operates the numeric / symbol key 12a and the function / operator key 12b to operate any function. An expression is input (step C12). Thereby, graph data is generated according to the input function formula (step C13), and the generated graph data is written in the first layer image storage area 15b of the RAM 15 (step C14).

  Here, assuming that the flag representing the layer to be displayed is n, first, n = 0 is set (step C15). Then, the graph data stored in the first layer image storage area 15b of the RAM 15 and the image data (background image) stored in the second layer image storage area 15c are combined and developed in the display data storage area 15a of the RAM 15. (Step C16), the composite image is displayed on the screen of the display unit 13 (Step C17).

  That is, when n = 0, the image data of the second layer is displayed on the entire screen as the background, and the graph data of the first layer is displayed on top of it. In this state, when the “switch” key 12h provided in the key input unit 12 is operated by the user (Yes in Step C18), the display target layer as described below is switched according to the value of the flag n. (Step C19).

  That is, when n = 0 when the “switch” key 12h is operated, the second layer is displayed and the image data (background image) stored in the second layer image storage area 15c of the RAM 15 is displayed. ) Are expanded in the display data storage area 15a of the RAM 15 and displayed on the screen of the display unit 13 (step C21). At this time, when the capture image processing mode is set in advance, the above-described processing is performed on the image data (step C20).

  After the display, n = 1 is set, and the process returns to Step C18. When n = 1 and the “switch” key 12h is operated, the first layer is to be displayed, and only the graph data stored in the first layer image storage area 15b of the RAM 15 is stored in the display data of the RAM 15. It is expanded in the area 15a and displayed on the screen of the display unit 13 (step C23). Since the graph data is real data that can be operated by keys, no processing is performed.

  After the display, n = 2 is set, and the process returns to Step C18. If n = 2 and the “switch” key 12h is operated, the process returns to step C15, and the background image and the graph data are again synthesized and displayed on the screen of the display unit 13 (step C16, C17).

(D) Creation of Electronic Learning Material Next, the case where a captured image is used for electronic learning material data will be described.

  The electronic computer 10 has an electronic teaching material function called “e-Activity” as a learning support tool for learning a graph function. This electronic teaching material function is used by a teacher to create a teaching material, but is also used by a teacher to create an operation guide in order to explain complicated scientific calculator operations to students in an easy-to-understand manner. As the operation guide, an image with the entire screen capped is used, and the captured image is pasted on the electronic teaching material data and provided to the student.

  FIG. 7 is a flowchart showing a processing operation related to electronic teaching material creation executed by the CPU 11 provided in the electronic computer 10.

  When the user selects “Create electronic teaching material” by operating the “MENU” key 12c provided in the key input unit 12 (Yes in step D11), an input screen for creating electronic teaching material (not shown) is displayed on the display unit 13. (Step D12).

  Arbitrary text or images can be input on this electronic teaching material creation input screen. If the input is text (Yes in step D13), the character / symbol string of the electronic teaching material data is input by operating the numerical value / symbol key 12a (step D14).

  On the other hand, if it is an image input (Yes in step D15), a captured image of a screen displaying a function graph to be learned is selected (step D16), and the image data is pasted on the electronic teaching material data (step S16). D18). At this time, when the capture image processing mode is set in advance, the above-described processing is performed on the image data (step D17).

  When saving is instructed after the text or image is input (Yes in step D19), the electronic teaching material data including the input text or image is named and stored in the electronic teaching material storage area 15e of the RAM 15. (Step D20).

(E) Electronic teaching material execution (capture image display 2)
FIG. 8 is a flowchart showing processing operations related to execution of the electronic teaching material executed by the CPU 11 provided in the electronic computer 10.

  When the user selects “execute electronic teaching material” by operating the “MENU” key 12c provided in the key input unit 12 (Yes in step E11), a file of electronic teaching material data is selected from the electronic teaching material storage area 15e of the RAM 15. The corresponding electronic teaching material data is read out (step E12).

  Here, when the image data is pasted on the read electronic teaching material data (Yes in Step E13), the image data is expanded in the display data storage area 15a of the RAM 15 and is displayed on the screen of the display unit 13. (Step E15). At this time, when the capture image processing mode is set in advance, the above-described processing is performed on the image data (step E14).

  On the other hand, if it is not image data (No in step E13), the character / symbol string of the electronic teaching material data is expanded in the display data storage area 15a of the RAM 15 and displayed on the screen of the display unit 13 (step E16). .

  Thereafter, the next data is sequentially read out in accordance with the scroll operation by the cursor key 12i (steps E17, E18, E19), and the image data is displayed after the processing as described above.

  Next, processing for processing a captured image will be described.

  FIG. 9 is a diagram showing a state in which a normal image is displayed. 10 and 11 are diagrams showing a state where a captured image after processing is displayed.

  As shown in FIG. 9, in a state where the normal image 21 is displayed on the display unit 13, a battery mark 22 indicating the remaining battery level is displayed at a predetermined position on the upper part of the screen. The normal image 21 is an image that can be operated by key input, and is appropriately updated when the user operates the key input unit 12.

  On the other hand, the captured image 23 is a fixed image captured by the screen capture function described above, and a key input operation cannot be performed. In order to distinguish this captured image 23 from the normal image 21, at the timing described above (A14 in FIG. 4, B15 in FIG. 5, C20 in FIG. 6, D17 in FIG. 7, E14 in FIG. 8), FIG. The processing as shown in FIG.

  FIG. 10 shows an example in which a screen frame 24 is added to the captured image 23. FIG. 11 shows an example in which the battery mark 22 is deleted from the captured image 23 and a message 35 is added at a predetermined position on the screen. With such a display form, the user can easily determine that the currently displayed image is the captured image 23, and does not mistake the normal image 21 for key input operation.

  In the example of FIG. 11, the battery mark 22 is deleted. However, information other than the battery mark 22 may be deleted as long as the information is not related to the key input operation or calculation.

  As described above, according to the present embodiment, since the captured image can be displayed separately from the normal image that can be operated by key input, the user can visually grasp that the captured image is displayed and perform an incorrect operation. No more to do.

  In addition, as processing for distinguishing the captured image from the normal image, information (frames, character strings, icons, etc.) is added to clearly indicate that the image is captured from the screen, or related to key input operations. By deleting the information (battery mark or the like) that is not to be performed, it is possible to notify that the image is a captured image without performing significant processing on the image.

  Further, as shown in FIG. 4, if the processing for distinguishing display is performed when the captured image is stored, it is not necessary to perform the processing every time the captured image is displayed. There is an advantage that it can be displayed quickly.

  Further, as shown in FIGS. 6 and 8, if the processing for distinction display is performed when the captured image is displayed, the captured image can be held as it is in the original state, that is, the state when the screen is captured.

  In addition, as shown in FIG. 5, if the processing for distinguishing display is performed when setting the captured image to a layer different from the normal image in the background setup, the layer switching display can be performed smoothly, and only the background is displayed. When displayed, it can be known that it is a captured image.

  In addition, as shown in FIG. 7, if processing for distinguishing display is performed when a captured image is pasted to electronic teaching material data, an image displayed on the screen when the electronic teaching data is used by a student. Can be informed that it is a captured image.

  If the screen frame is added with a prominent color such as red to the captured image by making use of the characteristics of the computer 10 capable of color display, the captured image can be more surely known when displayed. be able to.

  In addition, each operation method by the electronic computer 10 described in the above embodiment, that is, the method shown in each flowchart of FIGS. 4 to 8 is a memory card (ROM card, RAM card, etc.) ), Magnetic disk (flexible pull disk, hard disk, etc.), optical disk (CD-ROM, DVD, etc.), semiconductor memory, and other storage media. The computer (CPU 11) of the electronic computer 10 can execute the same processing by the method described above by reading the program recorded in the storage medium.

  Further, program data for realizing the above technique can be transmitted as a program code form via a communication network (public line). And the computer (CPU11) of the electronic computer 10 can perform the same process by the method mentioned above by receiving this program in the communication apparatus (communication control part 18) connected to the communication network.
