- the movement information is information for identifying a first case where the movement of the human body in which the capsule endoscope 13 is inserted is relatively small and a second case where the movement of the human body is relatively large. If the motion amount is less than the predetermined threshold, the motion analysis unit 204 generates motion information indicating the first case. If the motion amount is equal to or greater than the predetermined threshold, the motion analysis unit 204 generates motion information indicating the second case.

- the battery remaining amount estimation unit 205 estimates the remaining amount of the battery of the capsule endoscope 14 by the following method. For example, the battery remaining amount estimating unit 205 estimates the remaining amount of the battery of the capsule endoscope 14 based on the number of images captured by the imaging unit 100. The battery remaining amount estimation unit 205 may estimate the remaining amount of the battery of the capsule endoscope 14 based on the time elapsed since the capsule endoscope 14 started operation. The battery remaining amount estimating unit 205 may estimate the remaining amount of the battery of the capsule endoscope 14 based on the current position (a specific organ or the like) of the capsule endoscope 14. For example, the battery remaining amount estimation unit 205 detects the current position of the capsule endoscope 14 by analyzing the image received from the capsule endoscope 14.
- the threshold selection unit 206 selects any one of a plurality of thresholds in accordance with the remaining amount of the battery of the capsule endoscope 14.
- the threshold is a threshold of mode determination based on an analysis result of an image and a threshold of mode determination based on an analysis result of data.
- the threshold selection unit 206 has a table in which the remaining amount of the battery of the capsule endoscope 14 and the threshold are associated. In the table, with respect to the remaining amount of the battery of the capsule endoscope 14, a threshold of mode determination based on an analysis result of an image and a threshold of mode determination based on an analysis result of data are respectively associated. The lower the battery level, the larger the threshold. That is, as the remaining amount of the battery is smaller, the first mode is more easily set in the imaging unit 100.
- the wireless communication unit 200 wirelessly receives the image transmitted from the capsule endoscope 14. Further, the wireless communication unit 200 wirelessly transmits the threshold value selected by the threshold value selection unit 206 to the capsule endoscope 14.
- the wireless communication unit 200 may wirelessly transmit, to the capsule endoscope 14, information (such as an ID of a threshold) specifying the threshold selected by the threshold selection unit 206.
- the wireless communication unit 200 may receive, from the capsule endoscope 14, information indicating the remaining amount of the battery of the capsule endoscope 14. In this case, the wireless communication unit 200 functions as a battery remaining amount estimating unit.
- the eighth embodiment when the remaining battery level of the capsule endoscope 14 is small, smaller threshold values are set in the image analysis unit 102 and the data analysis unit 103 of the capsule endoscope 14. For this reason, when the first mode is set to the imaging unit 100, it is difficult to switch the mode to the second mode. In addition, when the second mode is set in the imaging unit 100, the mode is easily switched to the first mode. Therefore, the power consumption of the capsule endoscope 14 can be reduced.
- the imaging mode can be controlled with higher accuracy.
