Abstract: In transmitting images picked up by an intrabody introduced device to outside a test body, synchronizing signals of the image signal are set to signal patterns in the same high-frequency band as for the image signal and not used for the image signal. This enables a receiver to stably binarize the synchronizing signal and thus to acquire favorable image signal. For example, in a clipping circuit provided in a signal processing circuit in a capsule type endoscope (an example of an intrabody introduced device), image information of a high-intensity portion is clipped out of image information acquired by an imaging section and a pattern generation circuit allocates signal patterns within the clipped intensity range as horizontal and vertical synchronizing signals.

Abstract: The invention provides a receiving apparatus that can suppress data loss when an antenna is detached. When a non-connection of an antenna is detected (step S103: Yes) after a recording operation is started (step S101: Yes), the receiving apparatus operates a warning unit to issue a warning to a user to the effect that the antenna is detached (step S105). Therefore, the receiving apparatus does not issue a warning (step S102) when there is no problem even when the antenna is detached, such as when an examination is not yet started (step S101: No). When the antenna is detached in a state that the use of the antenna is essential during an examination, the receiving apparatus notifies the user such as a subject about this fact, thereby prompting the user to correct the connection of the antenna. As a result, the data loss when the antenna is detached can be suppressed.

When an ejection operation of the portable recording medium is detected (step S103: Yes) during a recording operation (step S101: Yes), a warning unit is operated before the portable recording medium is ejected to give a warning to a user so as not to perform the ejection operation (step S105). Accordingly, the portable recording medium can be prevented beforehand from being ejected during the recording operation, thereby preventing body cavity image data from being lost and the portable recording medium from being damaged.
