摘要： A portable simplified image display apparatus and a receiving system are provided, which can sensuously know the state of received strength of radio signals transmitted from a body-insertable apparatus, in either case of before examination or during examination. A viewer (7) includes a detector that detects received strength of a radio signal transmitted from a capsule endoscope (2) and a notifying unit that notifies the detected state of received strength in a display pattern such as a picture display of a capsule (41). Therefore, in either case of before examination or during examination, the state of received strength of radio signals transmitted from the capsule endoscope (2) can be sensuously known according to the notification result of the state of received strength. If it is during examination, supplementary observation can be performed based on an excellent received image by searching a site having strong received strength, thereby enabling contribution to satisfactory examination.

摘要： To realize a receiving system that can excellently receive radio signals before and after a body insertable device, which is a radio signal source, is inserted into a subject, the receiving system has a first receiving antenna (1), a second receiving antenna (2), and a receiving apparatus (3). The first receiving antenna (1) is used when the body insertable device is outside the subject. The second receiving antenna (2) is used when the body insertable device is inserted into the subject. The receiving apparatus (3) performs a receiving processing on radio signals received through the first receiving antenna (1) or the second receiving antenna (2). In the receiving system, a receiving antenna connected to an antenna connector (13) provided in the receiving apparatus (3) is switched between the first receiving antenna (1) and the second receiving antenna (2) corresponding to a difference in propagation states of radio signals transmitted from the body insertable device before and after the body insertable device is inserted into the subject. Consequently, the receiving system that can excellently receive the radio signals before and after the body insertable device is inserted into the subject is realized.

摘要： Each of detecting circuits 36a, 36d, 36f, and 36h detects a key signal such as a horizontal synchronization signal, a vertical synchronization signal, a capsule ID, a WB coefficient, and error information, i.e., a key signal superposed on RF signals received by an RF receiving unit 33. Each of determining units 36b, 36c, 36e, 36g, and 36i determines whether an image is valid or invalid based on the result of detection. A recording deciding unit 36k decides whether to record the image information in a storage unit 35 or not based on the result of determination. Thus, a receiving apparatus 3 can stop recording the image information received when a trouble occurs, thereby preventing defective images from mixing into the recorded image information, and preventing a recorded image size from becoming large, whereby necessary images can be recorded within a predetermined examination time.

摘要： An object of the invention is to receive, with a high sensitivity, a radio signal transmitted within a short time before a capsule endoscope reaches the stomach of a subject and acquire, in a satisfactory state, information on the interior of the subject such as image data picked up by the capsule endoscope. The receiving apparatus according to the invention includes a plurality of receiving antennas including a specified receiving antenna for receiving a radio signal from a capsule endoscope before the stomach is reached, a switching controller, an arrival determining unit and a mode switching unit. The switching controller performs a control operation for switching to and maintaining the receiving antenna in an initial mode or a control operation for switching to the receiving antennas in a normal mode. The arrival determining unit determines whether the capsule endoscope has reached the stomach or not. The mode switching unit instructs the switching controller to perform the control operation for switching to the initial mode, and upon determination that the stomach has been reached, gives the instruction to perform the control operation for switching to the normal mode.

摘要： 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.
