Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

Hereinafter, a wireless capsule endoscope having a variable frame rate according to an embodiment of the present invention will be described in detail with reference to the drawings.

1 to 3, a wireless capsule endoscope 100 having a variable frame rate according to an exemplary embodiment of the present invention includes a first image collecting unit 110, a second image collecting unit 120, 130).

As shown in FIG. 1, the wireless capsule endoscope 100 having such a variable frame rate is inserted into a digestive organs inside the human body and moves along the digestive organs to photograph the digestive organ's inner wall W. At this time, the wireless capsule endoscope 100 having a variable frame rate photographs at a low frame rate until it searches for a region of interest or detects an abnormal region, and shoots at a high frame rate for a region of interest or an ideal region, Can be obtained. The photographed image is transmitted to the external receiver 10 by wireless communication. Here, the digestive organs may be gastrointestinal tracts including gastric, small intestine, and large intestine.

Specifically, as shown in FIGS. 1 and 2, the first image collecting unit 110 is fixedly disposed in front of the moving direction of the wireless capsule endoscope 100. Since the first image collecting unit 110 is fixed, it is possible to collect images for a predetermined angle, for example, 170 ° forward. At this time, the first image collecting unit 110 photographs at a low frame rate. The first image collecting unit 110 includes a first LED 112, a first lens 114, a first camera 116, and a first image processing unit 118.

The first LED 112 has a lighting function for photographing so as to facilitate acquisition of an image in a digestive organs having low illumination. That is, the first LED 112 is disposed in front of the wireless capsule endoscope 100 and emits light to the digestive organs. These first LEDs 112 may be disposed on both sides of the first camera 116 as a pair.

The first lens 114 is disposed in front of the first camera 116 to adjust the focus of an image to be photographed. The first lens 114 may be a convex lens in the digestive organs, the focus of which is easy to adjust with respect to the object to be imaged.

The first camera 116 captures the inside of the digestive organs by the light emitted by the first LED 112. The first camera 116 can take an image at a low frame rate.

The first image processing unit 118 may process the photographed image from the first camera 116 and transmit the processed image to the external receiver 10 through the RF transmitter 136. [ The first image processing unit 118 can determine the region of interest from the photographed image. Alternatively, the first image processing unit 118 may determine the region of interest according to the selection from the external receiver 10. At this time, the first image processing unit 118 may transmit a control signal to start the operation to the second image collecting unit 120 when a region of interest is sensed.

The second image collecting unit 120 is rotatably disposed at a central portion of the wireless capsule endoscope 100 at the rear of the first image collecting unit 110, as shown in FIGS. Since the second image collecting unit 120 is rotatable by 360 degrees, the second image collecting unit 120 can collect lateral images with respect to all angles. At this time, the second image acquisition unit 120 performs an operation when an abnormal region is detected according to the sensing result of the diameter sensing unit 134. Also, the first image collecting unit 110 may be turned off while the first image collecting unit 110 searches for the ROI, and may be turned on when the ROI reaches the ROI. For this purpose, the first image collecting unit 110 and the second image collecting unit 120 can communicate with each other.

As described above, the second image acquisition unit 120 acquires a clear, high-resolution image of a region of interest or an abnormal region, and shoots at a higher frame rate than the first image acquisition unit 110. The second image collecting unit 120 may include a second LED 122, a second lens 124, a second camera 126, a second image processing unit 128, and a stepping motor 129.

The second LED 122 has a lighting function for photographing so as to facilitate the acquisition of the image in the digestive organs having low illumination. That is, the second LED 122 is disposed on either side of the middle part of the wireless capsule endoscope 100 to irradiate light to the digestive organs. These second LEDs 122 may be disposed on both sides of the second camera 126 as a pair.

The second lens 124 may be disposed in front of the second camera 126 to adjust the focus of an image to be photographed. The second lens 124 may be a convex lens in the digestive organs, the focus of which is easy to adjust for an object to be imaged.

The second camera 126 photographs the inside of the digestive organs by the light emitted by the second LED 122. The second camera 126 may capture an image at a higher frame rate than the first camera 116.

The second image processing unit 128 may process the photographed image from the second camera 126 and transmit the processed image to the external receiver 10 through the RF transmitter 136. [

The step motor 129 can drive the second image collecting unit 120 to be rotatable. This stepping motor 129 can be adjusted by the user observing the image through the external receiver 10. That is, the second image collecting unit 120 may be rotated by receiving the direction control signal from the external receiver 10 according to the user's selection.

As described above, the wireless capsule endoscope 100 having a variable frame rate includes two image collecting units, one of which is fixed as a search unit for collecting images at a low frame rate, and the other is for a region of interest It is rotatable for high-resolution shooting and captures images at a high frame rate. Hereinafter, the "fixed unit" has the same meaning as the fixed first image capturing unit 110, and the "rotating unit" is described in the same sense as the rotatable second image capturing unit 120.

The other processing unit 130 provides movement of the wireless capsule endoscope 100 having a variable frame rate and image transmission and power to the outside and includes a driving unit 132, a diameter sensing unit 134, an RF transmitter 136, And a power supply unit 138.

The driving unit 132 can drive the movement of the wireless capsule endoscope 100. [ This driving unit 132 can be driven by an operation from an external receiver 10. Alternatively, the driver 132 may be driven to move itself.

 At this time, when the driving unit 132 moves by itself, the driving unit 132 moves fast during photographing at a low frame rate by the first image collecting unit 110, which is a searching process, The image capturing unit 120 can move slowly when photographing at a high frame rate.

Alternatively, when the wireless capsule endoscope 100 is driven by the external receiver 10, irrespective of whether it is being taken by the first image collecting unit 110 or the second image collecting unit 120 And can move at a speed corresponding to the control from the external receiver 10.

In addition, when the driver needs to perform high-resolution imaging such as a region of interest or an abnormal region, the driver 132 may stop at a predetermined position and wait.

The diameter sensing portion 134 can sense the diameter of the inner wall of the digestive organs. The diameter sensing unit 134 may sense the diameter of the inner wall of the digestive organs through the image acquired by the first image collecting unit 110, for example. Alternatively, the diameter sensing portion 134 may sense the diameter of the inner wall of the digestive organs using a medium such as ultrasound radiation.

More specifically, the diameter sensing unit 134 senses the diameter of the inner wall of the digestive organs from the image acquired from the first image collection unit 110 and compares it with a pre-measured diameter in a normal case, i.e., , Can be detected as an abnormal region of the digestive system. At this time, if the diameter of the inner wall of the digestive organ changes due to the abnormality, the diameter sensing unit 134 may notify the second image collecting unit 120 to photograph the entire surface.

The RF transmitter 136 wirelessly transmits the images collected by the first image collecting unit 110 and the second image collecting unit 120 to the external receiver 10 via the antenna 137.

The power supply unit 138 may be wirelessly charged from an external receiver 10 or a separate wireless charger. Such a power supply unit 138 may be charged by wireless power charging periodically from the receiver 10 or a separate wireless charger.

With this configuration, compared with the case of photographing the entire digestive organ at one frame rate or photographing by the camera fixed forward or backward due to the fixed photographing angle with respect to the moving direction, It is possible to obtain a high-resolution image and at the same time to reduce power consumption.

Hereinafter, an image transmission method of a wireless capsule endoscope having a variable frame rate according to the present invention will be described with reference to FIG.

A wireless capsule endoscope image transmission method (400) having a variable frame rate comprises the steps of (S401, S402) searching for a region of interest by injecting a wireless capsule endoscope into the human body, (S404), and transmitting the collected image (S405).

To be more specific, first, the wireless capsule endoscope 100 having a variable frame rate is swallowed, and the resultant is injected into the digestive organs inside the human body (step S401).

Next, the first image capturing unit 110 fixedly disposed in front of the moving direction of the wireless capsule endoscope 100 having a variable frame rate searches for a region of interest or an ideal region while photographing at a relatively low first frame rate (Step S402).

At this time, the second image collecting unit 120 may be turned off to photograph the image at a low frame rate by the first image collecting unit 110 and to prevent unnecessary power consumption. Here, the wireless capsule endoscope 100 having a variable frame rate can be controlled such that the moving speed of the wireless capsule endoscope 100 is controlled by the driving unit 132 and moves quickly to search for a region of interest or an abnormal region.

Alternatively, as the image is transmitted from the first image collection unit 110, the inside of the digestive organs can be observed from the image displayed through the monitor of the external receiver 10, and the region of interest can be selected.

In this process, the photographed image can be wirelessly transmitted to the external receiver 10.

Next, the diameter of the inner wall of the digestive organ is sensed from the image captured by the first image collection unit 110, and the abnormal region is determined according to the sensing result (step S403). It is possible to sense the diameter of the inner wall of the digestive organ from the image obtained from the first image collecting unit 110 and compare it with the diameter previously measured in a normal case, that is, in a steady state.

At the same time, the first image collection unit 110 can determine the region of interest from the photographed image. At this time, the region of interest may be selected from the external receiver 10.

As a result of the determination in step S403, if it is determined that the area is not an area of interest or is not an abnormal area, the process proceeds to step S402 and continues shooting until a region of interest or an abnormal area is detected at a low frame rate.

If it is determined in step S403 that an area of interest or an abnormal area is detected, the target area is photographed by the rotating unit at a high frame rate (step S404). In other words, the second image capturing unit 120 rotatably disposed at the center of the wireless capsule endoscope 100 at the rear of the first image capturing unit 110 photographs the target area in detail. Here, the second image acquisition unit 120 may perform imaging at a second frame rate higher than the first frame rate of the first image acquisition unit 110.

At this time, the driving unit 132 may control to move slowly at a slower speed than the search process of step S402 for detailed photographing of the target area.

Next, an image photographed at a high frame rate with respect to the target area may be wirelessly transmitted to the external receiver 10 through the RF transmitter 136 (step S405).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
