Next, the control operation of the enlarged display device will be described. 4 is a flowchart showing the control operation of the CPU 51. When the power supply of the control device 6 is turned on, first, in step S1, initialization is performed to reset the registers and flags in the CPU 51. In step S2, the contents of the screen memory 53 are cleared. In step S3, the shutter switch 7 is turned on.

On the other hand, the operator sets the sample on the sample table 43 before capturing an image in the microscope 1, and the eyepiece 41
Then, the focus is adjusted while observing the image, and then the optical path switching switch 44 is switched to the CCD camera 5 side. After completing these preparations, the shutter switch 7 is turned on. When the shutter switch 7 is turned on, the program moves to step S4. In step S4, the image captured by the CCD camera 5 is read, amplified, A / D converted, and the screen memory 53 is read.
Write in. In step S5, the image written in the screen memory 53 is transferred to the OHP 3 via the cable 2, or the flexible disk 8c or the IC card 8 is used.
It is determined whether or not to record on a recording medium such as d. This judgment is
Judgment is made based on the operation content of the keyboard 9 by the operator. If it is determined that the data is once recorded on the recording medium, the process proceeds to step S6. In step S6, the image data is read line by line from the screen memory 53. In step S7, compression processing is applied to the read image data. In this compression process, image data is compressed by a known encoding process used in, for example, a facsimile. In step S8, the compressed image data is recorded on the flexible disk 8c or the IC card 8d. Step S9
Then, it is determined whether or not the processing of all lines is completed. The process returns to step S6 until the processing of all lines is completed. When the processing of all lines is completed, the process returns to step S2.

On the other hand, when it is determined that the data is transferred via the cable 2, the process proceeds from step S5 to step S10. In step S10, the image data is read line by line from the screen memory 53. In step S11, the read image data is transferred to the OHP 3 via the cable 2. In step S12, it is determined whether the transfer of all lines is completed. The process returns to step S10 until the transfer of all lines is completed, and returns to step S2 when the transfer of all lines is completed.

FIG. 5 shows a control flowchart of the CPU 33. First, in step S21, the registers and flags in the CPU 33 are initialized. In step S22, the screen memory 32 is cleared. In step S23, it is determined whether image data is received via the cable 2. In step S24, it is determined whether the operator has instructed the reading of the image data from the flexible disk 8c or the IC card 8d by using the remote controller 19. Similarly, in step S25, it is determined whether or not another process is instructed by the remote controller 19. Step S
When the determination in 25 is NO, the process returns to step S22.

When it is determined that the image data is received via the cable 2, steps S23 to S26 are performed.
Move to. In step S26, the received image data is written in the screen memory 32 line by line. Step S
At 27, it is determined whether or not the writing of all lines is completed. Step S2 until writing of all lines is completed
Returning to step 6, when writing of all lines is completed, step S
In step 28, the image data once written in the screen memory 32 is read line by line. In step S29, L
Image data is displayed on the CD 17 line by line. In step S30, it is determined whether or not the display of all lines is completed, and the process returns to step S28 until the display of all lines is completed. When the display of all lines is completed, the process proceeds to step S24.

When it is determined that the image data is read from the flexible disk 8c or the IC card 8d, the process proceeds from step S24 to step S31. In step S31, the compressed image data recorded on the flexible disk 8c or the IC card 8d is read line by line. In step S32, the read image data is expanded by a known decoding method. In step S33,
The expanded image data is written in the screen memory 32 line by line. In step S34, it is determined whether or not writing of all lines is completed, and the process returns to step S31 until writing of all lines is completed.

In step S35, the image data written in the screen memory 32 is read line by line. In step S36, an image is displayed on the LCD 17. In step S37, it is determined whether or not the display of the image data of all lines is completed, the process returns to step S35 until the display of all lines is completed, and when the display of the images of all lines is completed, the process proceeds to step S25.

If the command is for another process, the process proceeds from step S25 to step S38, and another process corresponding to the command is performed. Here, since the image captured by the microscope 1 can be displayed on the OHP 3 directly or via the recording medium, the image on the microscope 1 can be easily enlarged and projected on the OHP 3. [Other Embodiments] (a) In the above embodiment, the image captured by the microscope is
Although enlarged and displayed with P, the present invention is not limited to this. For example, instead of the OHP, a toner display device may be used in which toner is attached to the recording sheet and displayed. Also in this case, the image taken by the microscope can be easily enlarged and displayed. (B) In the above embodiment, RS232C is used as the connection medium.
Although the interface, the flexible disk, and the IC card are exemplified, the connection medium is not limited to these.
