A capsule device and a method for the capsule device remain in a very low power state and monitor whether it enters a desired section of the gastrointestinal track. The capsule device is coated with an enteric material that is expected to dissolve after it enters the small bowel. In the monitoring state, the capsule device captures a first image using the camera and the light source at a first frame rate substantially below a target frame rate. The capsule device compares first information related to the first image with second information related to a coating image corresponding to the coating. If the first information does not matches the second information, the capsule device declares that the coating has dissolved and the capsule device configures the camera to capture third images at the target rate after declaring that the coating has dissolved.

A light source illumination unit has operation modes including at least a normal electric power mode to operate with first electric power consumption, and a low electric power mode to operate with second electric power consumption lower than the first electric power consumption. A controller selects at least one of the operation modes in accordance with a use schedule, and controls the light source illumination unit in accordance with the selected operation mode.

A light source illumination unit has operation modes including at least a normal electric power mode to operate with first electric power consumption, and a low electric power mode to operate with second electric power consumption lower than the first electric power consumption.

A capsule endoscope system includes a capsule endoscope and a receiving device. The capsule endoscope outputs execution command at a timing at which work instruction data is received when movement speed is low, and outputs the execution command at a timing at which output of the execution command is instructed when the movement speed is high. The receiving device generates the work execution condition data and the work instruction data based on operations of an operator, and transmits the work execution condition data and the work instruction data to the capsule endoscope.

An on/off switching circuit includes an on/off switch switchable between an on state and an off state, an light emitting diode (LED) driver to power one or more LEDs to illuminate an area of interest, a switch control unit to transition the on/off switch between the on and off states, the switch control unit including a light sensing circuit comprising at least one LED of the LEDs as a light sensor, and a bi-directional gate circuit. When the on/off switch is in the off state the bi-directional gate is in a first conducting state in which the bi-directional gate circuit connects the light sensor to the light sensing circuit, and when the on/off switch is in the on state the bi-directional gate is in a second conducting state in which the bi-directional gate connects the LED driver to the one or more LEDs including the light sensor.

A capsule endoscope includes, inside a capsule casing, an information acquiring section that acquires information on an inside of a body of a subject, a battery that supplies power, a detection section that, upon detection of introduction to the inside of the body of the subject, outputs a detection signal, a signal receiving section that receives a control signal from an outside and outputs an internal signal, and a control section that controls power supply from the battery to the information acquiring section according to the internal signal and the detection signal.

A wireless endoscope includes: a detection portion configured to detect a connection state to an endoscope body of a battery; and a control portion configured to set a replacement time operation mode of using the power from a power storage component as the power needed for the endoscopic observation and performing the endoscopic observation with lower power compared to a normal time operation mode of performing an endoscopic observation with the power from the battery, when a detection result of a non-connection state of the battery is given from the detection portion, in which the control portion restores the normal time operation mode from the replacement time operation mode when a detection result of a reconnection state to the endoscope body of the battery is given from the detection portion.

The present invention discloses a control method, system, electronic device and readable storage medium for a capsule endoscope. The method includes: providing a working apparatus, comprising a capsule endoscope, and an external data recorder for cooperating with and controlling the capsule endoscope; monitoring the received ambient power by the external data recorder before wireless transmission of the capsule endoscope or during an intermittence between two transmissions, and/or monitoring the output power of the capsule endoscope by the external data recorder as data is transmitted during wireless transmission; adjusting the operating state of the working apparatus according to the ambient power and/or output power. The present invention can monitor the power during the dormant period before image interaction and/or in the process of image interaction, thus adjust the operating state of the capsule endoscope in real time, which can improve the wireless communication performance and operating time of the capsule endoscope.

Method for extending battery life and a capsule endoscope using the method are disclosed. According to this method, sub-tasks associated with capturing one image using the capsule endoscope when the capsule endoscope moves through a human GI (gastrointestinal) tract after being ingested by a human subject are identified. The capsule endoscope is capable of capturing an image sequence at a first frame period, and at least two sub-tasks are performed with partial or full overlap. One or more images are captured at a second frame period by performing sub-task spreading, where the sub-task spreading spreads the sub-tasks over time to reduce or avoid the partial or full overlap for said at least two sub-tasks so as to reduce a sub-task peak current or peak current duration. The second frame period is longer than the first frame period.

An endoscope apparatus includes an image pickup device, an illumination element, a power source unit, a processor, an image processing unit, and a monitor as a display unit. The illumination element is capable of executing illumination light reduction processing. The image pickup device is capable of executing frame rate reduction processing and pixel count reduction processing. When the processor selects a low power consumption operation mode, at least one of the illumination light reduction processing, the frame rate reduction processing and the pixel count reduction processing is executed, and the image processing unit performs image restoration processing relevant to the illumination light reduction processing, the frame rate reduction processing and the pixel count reduction processing.
