Description of the Invention: [Technical Field] The present invention relates to a method and apparatus for capturing an endoscope of a capsule, and more particularly to a capsule endoscope for taking a distance image. [Prior Art] According to the test, as early as 1795, many medical personnel began to inspect the digestive tract. The traditional inspection equipment is rough and inconvenient to use, and usually only for the front end of the elimination channel. Or the back end for examination, in order to improve the convenience of inspection, I have the idea of 2 endoscopes. The initial endoscopes were troublesome in terms of wire and operation, so the visibility was not ideal. After the fiber optic image transmission became more and more mature, the invention of the soft endoscope was improved, and the problem of insufficient initial endoscope bending was improved. Workers need to have a destructive face defect in (4) surgery, but the current examination of the public ΐ 'stomach, duodenum, can only go deep into the small intestine (10) to detect the head of the towel to a small _. _" Kindness _ Capsule endoscope itself is a fairly sophisticated electronic instrument with lens, image sense, wireless transmitter, antenna and electricity = == distinctive (four) sneeze, coffee torn 攸 m image shooting Or a wireless signal transmission, there will be more than 50,000 photos in total. No matter how much power you have. In addition, ^ is mixed with considerable power. Capsule endoscopes to carry out research threats (four), coffee, t _ miscellaneous need medical doctors Therefore, how to deal with the above _ ^ 1 when _, quite time-consuming and troublesome. Μ—a novel method that uses _distance to capture images 200927057' and reduces the capsule endoscopes that doctors judge, saving not only the time spent on capsule endoscope power. SUMMARY OF THE INVENTION It is an object of the present invention to provide a capsule endoscope that is imaged at a distance and that is mounted in a capsule endoscope by a mount-accelerator, and that is a special image when traveling at a fixed distance. To reduce the number of images shot, and thus save power. The object of the present invention is to provide a capsule endoscope for fixed-range imaging, which reduces the number of images to be captured by an accelerometer, thereby reducing the number of images transmitted by the wireless transmission module, thereby saving electric power. One of the objects of the present invention is to provide a capsule endoscope for taking a distance and taking an image to reduce the number of images taken by an accelerometer, thereby saving the doctor's time in judging the disease. The capsule endoscope of the fixed distance imaging of the present invention comprises a casing, an accelerometer, a signal processing circuit, a lighting image capturing module, a battery pack and a wireless transmission module. The accelerometer is disposed in the housing to sense an acceleration of the capsule endoscope to generate an acceleration signal; the signal is processed by a signal processing circuit disposed in the capsule endoscope, and the acceleration signal is twice integrated to obtain the capsule. The distance traveled by the mirror and generates a control signal when traveling a fixed distance; the illumination image capturing module disposed in the housing receives the control signal, and the image capture generates an electronic image signal; the wireless transmission disposed in the housing The module transmits the image signal radio frequency to the outside, and is received and stored by the externally located recorder. [Embodiment] In order to give the reviewer a better understanding and understanding of the features of the method of the present invention and the effects achieved, the preferred embodiment and the detailed description will be described as follows: Capsule endoscope Please refer to the first figure for the principle of taking a picture, which is a block diagram of a preferred embodiment of the present invention. As shown in the figure, the present invention is a fixed-length image capturing capsule endoscope 2' which comprises a casing 1, an accelerometer 10, a signal processing circuit 20, an illumination imaging module 30, and a non-200927057 line. The transmission module 40 is connected to a battery pack 5. The accelerometer 1 , the signal processing circuit 2 , the camera module 30 , the wireless transmission module 4 , and the battery pack 5 are all disposed in the casing 。. The accelerometer 1 senses the acceleration of the knee-lens endoscope 2 to generate an acceleration signal, wherein the accelerometer 1 is an axis accelerometer, a one-axis accelerometer or a three-axis accelerometer. The signal processing circuit receives the acceleration signal sent by the accelerometer 1,, and the second integral operation is as follows: v = ^adt s = jvdt where the 3-speed gamma acceleration value is "acceleration value a" The obtained velocity value, 5 is the distance value obtained by integrating the velocity value p. When the signal operation circuit 20 calculates the travel of the capsule endoscope 2 by a fixed distance, a control signal is generated. The illumination image capturing module 30 When the control signal transmitted by the signal processing circuit 2 is received, the image capture is performed. The image control circuit 36 generates a control signal to cause the light emitted by the light-emitting element 32 to be reflected by the object, and then the image is taken. The unit 34 optically images and converts the electronic signal 'to the wireless transmission mode, the group 40. Thus, the signal processing circuit 2 〇 when the displacement distance obtained by the operation of the acceleration signal exceeds Π Π 贞彳 贞彳 贞彳 贞彳 贞彳 贞彳 , , , , , , The image is taken by the image of the group 3, and the image of the image is 5 cm. (4). If the value is 3 public, the length of the human intestine is estimated to be 7 meters, and the capsule endoscope Required shooting The number of sheets is 7000/3, which is equal to 2,334 images. This is about 4 hours from the time when the capsule endoscope stays in the small intestine. It is only about one-tenth of the photographs of about 20,000 shots. The amount of image is reduced, and the power loss of shooting and wireless transmission is reduced. The capsule endoscope 2 of the present invention uses the displacement distance as a reference for the captured image, and there is no trouble of missing the captured image, and the number of captured images is much smaller than that of the image. The capsule endoscope, so the power required for the capsule endoscope 2 of the present invention is small, thereby saving the power of the capsule endoscope 2, and further, the number of images taken by the capsule endoscope 2 of the present invention It is much smaller than the general-purpose capsule endoscope, so the doctor is also faster than the general capsule endoscope in identifying the disease. The wireless transmission module 40 receives the image signal, processes the image signal to generate an RF signal, and transmits it to the outside of the body. In the recorder (not shown) to store the image taken by the capsule endoscope, for the identification of the disease, the image taken by the capsule endoscope 2 of the present invention. The number of photos is much smaller than that of the general capsule endoscope 'relatively'. The wireless transmission module 40 transmits less image signals, thereby achieving power saving effect. Moreover, the battery pack 50 is provided in the capsule endoscope 2 The power of the accelerometer 10, the signal processing circuit 20, the illumination image capturing module 30 and the wireless transmission module 4. The illumination imaging module 30 further includes a light-emitting component 32 and an image capturing unit 34. When receiving the control signal, the module 30 can activate the light-emitting component 32 to provide a light source, and simultaneously drive the image capturing unit 34 to generate an image signal according to the light source provided by the light-emitting component 32. Further, the illumination image capturing module 30 further includes An image control circuit 36, after receiving the control signal, generates a driving signal and transmits it to the light-emitting element 32 and the image capturing unit 34, respectively, to effectively control the light-emitting element 32 and the image capturing unit 34 to perform image capturing. The 'light-emitting element 32 is a light-emitting diode Qjght Emitting Diode (LED) or an organic light-emitting diode (OLED), and the image capturing unit 34 is a complementary gold-oxide semiconductor (c〇mplementary鼢) Shi
