TECHNICAL FIELD

[0001] The present application relates to the field of image detection, in particular to a capsule endoscope and an exposure device and system thereof. BACKGROUND

[0002] A capsule endoscope is a miniature device for non-invasive examination of the digestive tract, which includes a shell, an image collector and other components. The patient swallows the capsule endoscope into the stomach, and the capsule endoscope will gradually move down along with the peristalsis of the gastrointestinal tract, taking pictures of the mucosa of the inner wall of the digestive tract along the way, and transmitting the images to the body outside the recorder through radio frequency for image storage for subsequent image analysis. The capsule endoscope is usually a disposable device, so in order to ensure high use efficiency, one capsule endoscope will take pictures of the whole digestive tract in the patient's body.

[0003] However, the image collector of the current capsule endoscope generally only has one constant shooting mode. When the position of the capsule endoscope changes, the shooting mode may no longer be suitable for the current environment, resulting in overexposure or underexposure of the images obtained by the capsule endoscope, which cannot be accurately analyzed.

[0004] Therefore, how to provide a solution to the above technical problems is a problem that needs to be solved by the technical personnel in the field at present. SUMMARY

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Currently, capsule endoscope image acquisition devices generally only have one constant shooting mode. When the position of the capsule endoscope changes, the shooting mode may no longer be suitable for the current environment, resulting in overexposed or underexposed images obtained by the capsule endoscope, making accurate image analysis impossible.

[0039] The exposure device for capsule endoscope disclosed in this application can adjust the exposure mode according to the movement position, thereby improving the exposure effect at different movement positions, avoiding overexposure or underexposure, and improving the image analysis value of capsule endoscope.

[0040] This invention discloses an exposure device for a capsule endoscope, such as... Figure 1 As shown, it includes a memory 11 and a processor 12, wherein the memory 11 is used to store computer programs, and the processor 12 is used to execute the computer programs to perform the following steps, such as... Figure 2 As shown:

[0041] Acquire working data of the capsule endoscope in the cavity;

[0042] The movement position of the capsule endoscope in the cavity is determined using working data;

[0043] Determine the corresponding target exposure mode based on the movement position;

[0044] Control the capsule endoscope to operate in the target exposure mode.

[0045] It is understood that in this embodiment, the working data of the capsule endoscope in the cavity is used to determine the movement position of the capsule endoscope in the cavity, and then the target exposure mode suitable for the movement position is determined, so that the capsule endoscope operates according to the target exposure mode, thereby taking pictures that can clearly reflect the condition of the cavity.

[0046] Specifically, in this embodiment, the working data used to determine the movement position of the capsule endoscope in the cavity can be image data acquired by the capsule endoscope's image acquisition device, or motion state data of the capsule endoscope during movement in the cavity, such as movement time, speed data, inertial navigation data, or pressure data from the pressure sensor when the capsule endoscope is compressed by the cavity during movement. As long as the working data can be obtained by analyzing and determining the movement position of the capsule in the cavity and can be acquired by the hardware embedded in the capsule endoscope, it can be applied to this embodiment.

[0047] In some specific embodiments, the working data includes image data, and the process by which the processor 12 uses the working data to determine the movement position of the capsule endoscope in the cavity includes:

[0048] Image recognition is performed on the image data to determine the movement position of the capsule endoscope in the cavity.

[0049] Understandably, by performing image recognition on the image data acquired by the image acquisition device under the current exposure mode, the precise movement position of the capsule endoscope in the cavity can be determined. It can also be used to analyze whether the image data is clear, and then change the exposure mode to the target exposure mode that makes the image data clearer.

[0050] In some specific embodiments, the working data includes motion data.

[0051] In some specific embodiments, motion data includes motion time, and the process by which processor 12 uses working data to determine the motion position of the capsule endoscope in the cavity includes:

[0052] Determine the preset time period corresponding to the current exercise time within the total preset time period;

[0053] The movement position of the capsule endoscope in the cavity is determined according to a preset time period.

[0054] It is understandable that the capsule endoscope moves within the cavity as the cavity peristalsis occurs, thus exhibiting a regular movement pattern. Under normal circumstances, there is a certain correspondence between the movement time and the movement position of the capsule endoscope. For example, it may be in the stomach for the first hour and in the intestines for the next hour. Based on this correspondence, preset time periods are set for different movement positions, as well as a total preset time period corresponding to all preset time periods. The current movement time is analyzed within the preset time period corresponding to the total preset time period to determine the cavity path traversed by the capsule endoscope within the preset time period and the movement position of the capsule endoscope in the cavity at the current moment.

[0055] In some specific embodiments, motion data includes velocity data and / or inertial navigation data. The process by which processor 12 uses working data to determine the motion position of the capsule endoscope in the cavity includes:

[0056] The motion state of the capsule endoscope is determined based on velocity data and / or inertial navigation data.

[0057] The position of the capsule endoscope within the cavity is determined based on its motion state.

[0058] It is understandable that velocity data and / or inertial navigation data have different forms in different parts of the cavity. The cavity can be divided into narrow cavity and wide cavity. The velocity data and inertial navigation data in the narrow cavity and wide cavity have different characteristics, which can be used to determine the motion position of the capsule endoscope in the cavity at this time.

[0059] In some specific embodiments, the motion data includes pressure data from pressure sensors, and the process by which the processor 12 uses the working data to determine the motion position of the capsule endoscope in the cavity includes:

[0060] Determine the pressure data range corresponding to the current pressure data;

[0061] The movement position of the capsule endoscope in the cavity is determined based on the pressure data range.

[0062] It is understood that the target exposure mode to be adjusted in this embodiment is related to the spatial size of different parts of the cavity. The pressure data sensed by the pressure sensor also corresponds to the spatial size of different parts of the cavity. The complete cavity can be divided into different segments, each segment will correspond to a specific pressure data range, and at the same time correspond to a target exposure mode. Thus, the pressure data of the pressure sensor can be used to determine the movement position of the capsule endoscope in the cavity, and further use the movement position to determine its corresponding target exposure mode.

[0063] Furthermore, when determining the target exposure mode based on the motion position, the motion position can be mainly divided into narrow cavity and wide cavity. The target exposure mode can be mainly selected as average exposure mode or peak exposure mode. Specifically, when the motion position is in the wide cavity of the cavity, the target exposure mode is determined as average exposure mode; when the motion position is in the narrow cavity of the cavity, the target exposure mode is determined as peak exposure mode.

[0064] Understandably, in practical applications, the wide cavity is mainly the stomach in the digestive tract. Since the stomach has a large space, if the image acquisition device uses the peak exposure mode, the acquired image will be too dark. Therefore, in this embodiment, the target exposure mode is set to the average exposure mode in the wide cavity, thereby significantly improving the overall brightness of the image so as to clearly show the cavity condition.

[0065] Similarly, the narrow cavity is mainly the small intestine in the digestive tract. The space of the small intestine is narrow. If the image acquisition device uses the average exposure mode, the acquired image will be overexposed. Therefore, in this embodiment, the target exposure mode is set to peak exposure mode in the narrow cavity to reduce the possibility of image overexposure and to clearly show the cavity condition.

[0066] Understandably, current capsule endoscopes include structures such as a shell, circuit board, image acquisition unit, and communication module. The image acquisition unit mainly comprises a controller and a CMOS (Complementary Metal Oxide Semiconductor), while the communication module is primarily a radio frequency (RF) communication circuit. Within the capsule endoscope, the controller controls the CMOS to acquire images and transmits the image data to an external recorder via the RF communication circuit for image storage. The image data is then read by a PC from the external recorder. Therefore, in this embodiment, the exposure device of the capsule endoscope can be either internally located and automatically activated within the capsule endoscope, or externally located and interacts with the capsule endoscope via the RF communication circuit, including acquiring the capsule endoscope's operating data and controlling the capsule endoscope to operate in the target exposure mode.

[0067] This application discloses an exposure device for a capsule endoscope, including a memory and a processor. The memory stores a computer program, and the processor executes the computer program to perform the following steps: acquiring working data of the capsule endoscope in the cavity; determining the movement position of the capsule endoscope in the cavity using the working data; determining a corresponding target exposure mode based on the movement position; and controlling the capsule endoscope to operate in the target exposure mode. The capsule endoscope exposure device disclosed in this application can adjust the exposure mode according to the movement position, thereby improving the exposure effect at different movement positions, avoiding overexposure or underexposure, and enhancing the image analysis value of the capsule endoscope.
