Abstract: A receiving apparatus includes a receiving unit that receives an image signal, identification information on a transmitting apparatus, and color adjusting information that are radio transmitted from the transmitting apparatus; a lock controller that locks the color adjusting information when the receiving unit receives at least one of consecutively repeated identical color adjusting information and consecutively repeated identical identification information during a predetermined period or when the receiving unit most often receives at least one of the identical color adjusting information or the identical identification information during the predetermined period; and an image processing unit that performs image processing on the received image signal based on the locked color adjusting information.

Abstract: A receiving apparatus is for selecting and receiving a radio signal in a frame structure having an information body part including at least information body and an additional part including information for receiving field intensity measurement by using a plurality of antennas. The apparatus includes a controller that measures a receiving field intensity of not a first antenna which has received the information body in a transmission period of the additional part in a current frame but a second antenna, and measures a receiving field intensity of the first antenna in a transmission period of the information body part in the current frame, and if the receiving field intensity of the second antenna exceeds the receiving field intensity of the first antenna, selects and changes to the second antenna as the first antenna of a next frame.

Abstract: A receiving apparatus which is used while connected to a plurality of antennas, the receiving apparatus receiving a radio signal through the antennas to perform a predetermined process to the received radio signal, the radio signal being transmitted from a body-insertable apparatus inserted into a subject, includes a receiving antenna selection unit that selects the antenna which is suitable for reception of the radio signal when the radio signal is transmitted from the body-insertable apparatus; a sequential antenna selection unit that sequentially selects each of the plurality of antennas when performance inspection of the plurality of antennas is performed; and a signal processing unit that performs a predetermined process to the radio signal received through the antenna, the antenna being selected by the receiving antenna selection unit or the sequential antenna selection unit.

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: A capsule endoscope includes a storage unit that stores signal processing data necessary for signal processing specific to an imaging device of a capsule endoscope, and a transmitting unit that transmits the signal processing data stored in the storage unit. Besides, a capsule endscope system includes the capsule endoscope and a receiver which receives the signal processing data transmitted from the transmittting unit. The capsule endoscope does not perform signal processing specific to the imaging device but the receiver performs signal processing specific to the imaging device based on the received signal processing data.

Abstract: An in-body information acquiring apparatus includes a function executing unit that realizes a predetermined function inside a body of a patient. A power-supply circuit includes a power unit that includes a cell and that outputs a first current and a first voltage; and a converter that converts the first current to a second current, which is a current required to operate the function executing unit for a predetermined time, and converts the first voltage to a second voltage, which is a voltage required to operate the function executing unit.

Abstract: A capsule endoscope has a front cover having a window for illuminating light and a window for capturing images. The window for illuminating light is flat. The window for capturing images is flat or convex. Because the window for illuminating light is flat, the light passes through the window without being reflected toward an image capturing unit.

Abstract: In a capsule endoscope illuminating units are disposed around an image capturing unit in such a manner that an optical axis of the illuminating units do not intersect with an optical axis of the observation unit, and illumination areas of the illuminating units overlap at substantially a central portion of an image capturing area of the image capturing unit.
