- the information indicating the marking result may be referred to as marking information.
- FIG. 5 is a flowchart for explaining the operation of the receiving device 5.
- receiving device 5 receives a radio signal from capsule endoscope 2 via receiving antennas 4a to 4h (step S101)
- image demodulating by demodulator 24 and image by image processing circuit 25 are received.
- the image is stored in the portable recording medium 9 composed of CompactFlash (registered trademark) memory (step S102).
- the portable recording medium 9 for which image data has been saved is taken out from the receiving device 5 and then inserted into the workstation 8 so that the image data can be taken out and displayed at the workstation 8 described later. I have to.
- the control unit 26 receives the detection signal from the view one connection detection unit 30 and determines whether or not the view 7 is connected (step S103).
- step S 103 if view 7 is connected (step S 103: Yes), the image stored in portable recording medium 9 is transmitted to view 7 (step S10 4). If the view 7 is not connected (step S103: No), it is determined whether the power switch 12 has been pressed (step S105).
- step S105: No If the power switch 27 is not pressed in step S105 (step S105: No), it is determined that there is radio signal transmission from the capsule endoscope 2, and Return to step S101, receive the radio signal from the capsule endoscope 2, and repeat the above operation.
- step S 105: Yes When the power switch 27 is pressed (step S 105: Yes), it is determined that the transmission of wireless signals for all the images from the capsule endoscope 2 is completed, and the above operation is terminated. End.
- FIG. 6 is a flowchart for explaining the operation of the viewer 7. In FIG. 6, the case where the viewer 7 is equipped with a receiving antenna and a receiving unit for receiving a radio signal directly from an external force will be described.
- the control unit 38 receives a detection signal from the receiving device connection detecting unit 37, and determines whether or not the receiving device 5 is connected (step S201).
- step S201 if the receiving device 5 is connected (step S201: Yes), image data is acquired from the receiving device 5 via the interface 34 (step S202), and image processing is performed. Image processing is performed by the circuit 35 to obtain an image processing result (step S203).
- the control unit 38 displays the image-processed image (in-vivo image of the subject 1) in the image display area 1 la of the display unit 11, and sets the image processing result as the image mark 1 lb of the display unit 11. Are displayed (steps S204 and S205).
- step S206 determines whether the marking button 13 is pressed.
- step S206: YES When the marking button 13 is pressed in step S206 (step S206: YES), the control unit 38, for example, among the image data of the subject 1 displayed on the display unit 11, is shown. Marking is performed on the image data suspected of having a lesion (marking step), and the marking information and image processing result information (that is, the identification data described above) are transmitted to the receiving device 5 (step S207). , S208). If the marking button 13 is not pressed (step S206: No), only the image processing result information is transmitted to the receiving device 5 (step S208). The marking information and the image processing information are transmitted to the receiving device 5 in association with the frame number of the image, for example. Therefore, the control unit 26 of the receiving device 5 associates the marking information with the image of the frame number. And the image processing information can be stored in the portable recording medium 9.
- step S201 If the receiving device 5 is not connected in step S201 (step S201: No), the receiving unit receives a radio signal from the capsule endoscope 2 via a not-shown receiving antenna. The received image is received (step S209), and the received image is displayed on the display unit 11 (step S210).
