A capsule endoscope 3 as an example of a body-insertable apparatus includes a battery 100, a control information detecting circuit 31 to which driving power is supplied from the battery 100, a system control circuit 32, and a driving controller 34 that is arranged between the battery 100 and the control information detecting circuit 31 and the system control circuit 32. The driving controller 34 controls driving of the control information detecting circuit 31, the system control circuit 32 or the like based on a temperature detected by a temperature sensor unit 33, thereby preventing actuation of the capsule endoscope 3 outside the body of a subject.
摘要:
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.
摘要:
A communication apparatus (3) arranged outside a subject (1) has an external device (32) which sequentially transmits control signals. A capsule endoscope (2) is introduced inside the subject (1). Thereafter, a system control circuit controls a driving of an intra-capsule function executing circuit so as to start driving at a previously set given time, by supplying driving power to the intra-capsule function executing circuit to control the driving thereof based on a result of detection by a control-signal detecting circuit which is provided in the capsule endoscope (2) and which detects a discontinuous state of input of the control signals. Thus, a collection and transmission of images inside the subject can be performed accurately.

In response, a receiving unit receives a communication permission signal from the communication apparatus. A communication controller determines whether to transmit in-vivo information or not based on the state of reception of the communication permission signal.

An intra-subject device is introduced into a subject to acquire information of the interior of the subject and has a lighting member to output an illuminating light for illuminating the interior of the subject and an imaging member to acquire an image of the interior of the subject. The intra-subject device also has a parameter memory to store a parameter for canceling a noise contained in color information of the image. The intra-subject device also has a radio-transmitting section that radio-transmits the image information, to which the parameter stored in the parameter memory is added.
摘要:
An intrabody introduced device comprising: a power storage section for supplying driving power to a function executing section; a detecting section for detecting a supply voltage of the power storage section; and a timing output section for outputting a detection signal for use in detecting the supply voltage using the detecting section at given timing. The detection timing of the supply voltage can be controlled in this manner, and therefore the supply voltage can be detected at timing at which the load of function executing section is low, thereby enabling efficient voltage detection. For example, if the aforementioned timing is synchronized with the blanking period of a picked-up image, a stable voltage measurement is enabled at timing at which the intrabody introduced device applies a low load.
摘要:
The present invention relates to a compact imaging apparatus. A memory in which one-line data is temporarily stored is provided between an analog processing system and a digital processing system. The analog processing system performs a series of processing from obtaining a pixel signal with an image pickup element to conversion of the pixel signal into digital data, and the digital processing system performs signal processing of the digital data into predetermined imaging data. A controller exclusively controls a one-line analog system operation performed by the analog processing system and a one-line digital system operation performed by the digital processing system. The controller operates the analog processing system with a maximum-speed clock which is possessed by the analog processing system, and the controller operates the digital processing system with a clock corresponding to a frequency determined by a bandwidth of a transmission system which transmits the imaging data. The controller turns on power source supply necessary for the operation of the analog processing system in performing the analog system operation f1 of the analog processing system, and the controller turns off the power source supply necessary for the operation of the analog processing system in performing the digital operation f2 of the digital processing system.
