In order to improve the imaging quality of the lens in the capsule endoscope, the light-emitting part with the illumination function can be independently arranged on one surface of the rigid circuit board, and then the rigid circuit board is sleeved on the lens through the flexible circuit board which is connected with the rigid circuit board in a bending mode, so that the light-emitting part is exposed near one end, close to a shot object, of the lens. In this case, the cost is increased by designing the circuit board for the light emitting element; the flexible circuit board is easy to damage by bending and unstable in electric connection; before the flexible circuit board is bent, the size and the direction of the required bending force are difficult to accurately predict, and the positions of the light-emitting piece and the lens after bending are difficult to control and uniformly distribute; moreover, the joint of the flexible circuit board and the rigid circuit board has certain rigidity, after the flexible circuit board is bent, the flexible circuit board can restore partial deformation, so that the rigid circuit board cannot be perpendicular to the optical axis of the lens, one end of the rigid circuit board, which is connected with the flexible circuit board, is easily bent towards the image side of the lens, one end of the rigid circuit board, which is far away from the flexible circuit board, is easily tilted towards the light inlet of the lens, the range of the light-emitting element for illuminating an object is inconsistent with the range of the lens for capturing the reflected light of the object, and therefore the problem that the light-emitting element is close to the light inlet of the lens to cause the glare of the lens and cause the problem of overlarge light intensity distribution difference of each field of the lens is caused; moreover, the degree and the bent position of each flexible circuit board are difficult to be consistent, the automatic production is difficult, and the bending yield is unstable. The emergent light of illuminating part is in order to make the object of shooing illuminated, let the object of shooing can reflect more light and get into the camera lens, so that the image luminance that the camera lens obtained is higher, it is more clear, when the light that the illuminating part is emergent directly gets into the camera lens, because the light intensity of illuminating part emergent is great usually, when the light of big light intensity passes through the camera lens, some light will be reflected by each surface of lens and go back and become miscellaneous light or interference light, this kind of reflection in the camera lens inside can arouse a unreal image, and appear forming spot etc. bad phenomenon on last picture like the image, this is exactly the dazzling light problem of camera lens.

In addition, in order to make the volume of the camera shooting component in the capsule endoscope smaller, the light-emitting part can be arranged at one end of the lens barrel of the lens close to the shot object, the light-emitting part is very close to the light inlet of the lens, and the light emitted by the light-emitting part easily and directly enters the lens, so that the lens generates a dazzling problem; in addition, the lens structure is generally compact, and it is difficult to have enough space for disposing the light emitting element on the lens barrel, which is difficult to produce and has low yield.

Further, it is understood that the through hole 123 of the mount 12 penetrates the first mount part 121, and that the through hole 123 of the mount 12 penetrates the first mount part 121 and the second mount part 122 along the optical axis direction of the lens 11 to ensure light passing therethrough. Optionally, the lens barrel of the lens 11 has an external thread, the first mounting portion 121 of the lens holder 12 has an internal thread, the lens 11 is fixedly connected with the lens holder 12 through the thread, and the lens holder 12 is sleeved outside the lens 11, so that the lens holder 12 can well protect the lens 11, and the structural strength and stability of the lens 11 are improved; the lens barrel of the lens 11 may have an internal thread, the first mounting portion 121 of the lens holder 12 has an external thread, the lens 11 is fixedly connected with the lens holder 12 through the thread, and the lens 11 is sleeved outside the lens holder 12, so that the lens 11 may be longer, and the lens 11 is further away from the light emitting element 13, thereby preventing glare; the lens 11 and the lens holder 12 can also be fixedly connected by gluing, hot riveting, screws, etc.

It is understood that the first surface 1221 is a surface of the second mounting portion 122 facing the subject, and the connection between the first surface 1221 and the second surface 1222 is bent toward the image side, that is, the second surface 1222 is an outer peripheral surface of the second mounting portion 122. Further, the second mounting portion 122 is provided with a first recess 1228 and a second recess 1229, the first recess 1228 is located on the first surface 1221, the first recess 1228 is located outside the projection of the lens 11 on the first surface 1221, the second recess 1229 is located on the second surface 1222, and the first recess 1228 is communicated with the second recess 1229. The first recess 1228 is located outside the projection of the lens 11 on the first surface 1221, so that the lens 11 can prevent the first recess 1228 and the light-emitting member 13 from being blocked, and more light of the light-emitting member can reach the object to be shot.

Optionally, the second mounting portion 122 disposed around and adjacent to the first mounting portion 121 includes: the second mount portion 122 may be disposed around and adjacent to the first mount portion 121 from an end of the first mount portion 121 near the subject, that is, an end of the first mount portion 121 near the light entrance hole of the lens 11; the second mounting portion 122 may also be disposed around and adjacent to the first mounting portion 121 from an end of the first mounting portion 121 close to the image, that is, an end of the first mounting portion 121 far from the light inlet of the lens 11; the second mounting portion 122 may also be circumferentially and adjacently disposed between the end of the first mounting portion 121 near the subject and the end near the image. When the second mounting portion 122 is located at the end of the first mounting portion 121 away from the light inlet of the lens 11, the distance between the light emitting element 13 and the light inlet of the lens 11 is further increased, so that the light beam emitted by the light emitting element 13 cannot directly enter the field angle range of the lens 11, and glare caused by the light emitted by the light emitting element 13 entering the lens 11 is effectively reduced. Therefore, the light-emitting piece 13 can be well matched with the lens 11 in a proper direction, and the imaging definition is improved.

Optionally, a plurality of light emitting members 13 may be distributed on the first surface 1221 in a scattered manner, so as to better install the light emitting members 13; the plurality of light-emitting members 13 may also be uniformly distributed around the lens 11 on the first surface 1221, that is, the distance between any two adjacent light-emitting members 13 is equal, the overall light distribution of the light-emitting members 13 is more uniform, and a dark image is not likely to appear on a photographed object, so that a uniform light intensity distribution can be obtained in the field angle range of the lens 11, which is similar to the effect of a shadowless lamp, that is, the consistency between the range of the light-emitting members 13 illuminating the object and the field angle range of the lens 11 is better. If there are 4 light-emitting members 13, the 4 light-emitting members 13 are uniformly distributed around the lens 11 around the optical axis of the lens 11.
