Description

Image capturing apparatus

Technical Field

The present invention relates to an image photographing apparatus, and more particularly, to an image photographing apparatus which is exclusively used for photographing a contact surface of a specific organ which can be contracted and expanded and is normally in a tightly closed state.

Background

Image capturing apparatuses are generally used to capture images of various objects and display the captured images on a terminal device in an analog or digital manner. For example, cameras, video cameras, security monitoring devices, X-ray detectors, and the like are widely used image capturing apparatuses.

In the medical field, image capturing apparatuses are also commonly used to capture images of human tissue for examination by a doctor. For example, the CT machine may scan a human organ, convert the received differential ray signals into digital information according to the difference of the penetration ability of the X-ray, and output the finally obtained image to the terminal device. For another example, an X-ray fluoroscopy machine performs fluoroscopy on bones, teeth, etc. of a human body by means of X-rays, and after the X-rays emitted by an emitting end penetrate through an object to be detected, the receiving end receives the X-rays and processes the X-rays into an image for observation.

However, due to the complexity of the shape of each part of the human body, the above-mentioned penetration type image photographing device cannot completely replace the conventional optical type image photographing device. For example, the above-mentioned penetration type image capturing device cannot meet the requirement when it is necessary to capture an image of the contact surface of a certain organ (e.g., anus, vagina, etc.) in the human body, which is capable of contracting and expanding and is normally in a closed state. If a conventional optical type image capturing apparatus (e.g., a camera) is used, the sharpness of the captured image is generally not satisfactory because the contact surface of a specific organ to be captured is in a closed state. If the image photographing device is forcibly inserted into the specific organ in order to obtain a clear image, a lot of unnecessary pain is given to the patient.

For this reason, some relevant designs have been developed to address the above needs.

For example, a female ovulation monitor is disclosed in chinese utility model patent ZL96237417.2 filed by guangzhou Guangxi industrialists, Inc. in 1996, 9/3. The detector comprises a protective sleeve, a barrel, a microscope lens, a base and an illuminating circuit, wherein the illuminating circuit comprises a light-emitting diode, a resistor, a switch, a battery and the like, the microscope lens is movably arranged at one end of the barrel, the light-emitting diode extends out of the top of the base, the switch is arranged at the bottom of the base, the battery is arranged in the base, the whole base is movably sleeved at the other end of the barrel, and the microscope lens and the barrel can be sleeved by the protective sleeve. According to the record of the patent specification, the detector has the advantages of simple structure and circuit, convenient operation, quick and accurate detection result and lower cost, and can achieve the purposes of prepotency and family planning.

However, despite several advantages such as those claimed by the applicant, in practical use, the above-mentioned detector still has the following disadvantages:

(1) because the detector adopts a mode that a microscope lens is arranged at one end to observe the sample, the defects of inconvenient observation, low precision of the shot image and the like exist;

(2) the micro lens is arranged on the detector, so that the size of the detector is large, and the detector cannot go deep into a human body to observe. In fact, the utility model discloses a detector mainly used detects user's saliva sample, is used for going deep into the human body to shoot the image very little.

In response to the above problems, some improved detection instruments have been developed.

For example, a vaginal speculum using a camera-able color screen mobile phone as a display is disclosed in the chinese utility model patent ZL200820021135.6 filed by huhou-tengyu in 2008/28 th, wherein the vaginal speculum is composed of a duckbilled speculum, an external camera and a lighting lamp combination, the external camera and the lighting lamp are arranged on the duckbilled speculum, the external camera is connected with the camera-able color screen mobile phone through a wire, or the external camera is connected with the camera-able color screen mobile phone through a bluetooth transmission mode, so as to realize a display using the camera-able color screen mobile phone color liquid crystal display as the external camera.

The duckbill speculum is composed of a probing part entering the vagina and a handle part operated by a hand, wherein the probing part has a slender streamline shape in a closed state so as to be suitable for probing the vagina and ensure that no obvious adverse stimulation exists in the probing process. The probing part has a duckbill structure, which is beneficial to stretching the vagina which is originally attached to the front wall and the back wall, so that the shooting observation is convenient. The approach and the opening and closing of the approach part can be completely controlled by a self-tester by utilizing the handle part, so that the actions of approach, opening and rotating of the approach part are conveniently controlled, and the purposes of approach into the vagina and exposure of the vaginal wall, vaginal fornix and cervix are further achieved.

In addition, the purposes of opening vaginal folds to expose mucosa, poking and wiping leucorrhea adhered to vagina and cervix uteri and the like can be achieved by controlling the actions of the probing parts, so that a good camera shooting and observing effect is achieved. The included angles of different angles can be designed between the probing part and the handle part of the duckbill speculum, which is beneficial to adapting to the self-examination manipulation habit of a self-examiner.

However, although the duckbill speculum has a slender streamline shape, the slender structure of the speculum can still cause adverse stimulation to organs such as vagina and cervix, and the experience of a self-inspector is poor. In addition, when a self-tester uses such a slender instrument, the long length thereof also causes poor operability and further causes a reduction in detection accuracy.

On the other hand, the duckbill speculum is only suitable for a human body organ with a long introducible length, but cannot be suitable for a human body organ with a short introducible length, such as an anus.

Therefore, there is a need to design an image capturing device specifically for capturing the contact surface of certain organs in the human body that can be contracted and expanded and are normally in a closed state, which is simple and effective in operation, has a wide application range, and does not cause discomfort to the user.

Detailed Description

Preferred embodiments of an image capturing apparatus according to the present invention will be described below with reference to the accompanying drawings, in each of which like reference numerals refer to like parts.

[ first preferred embodiment ]

Referring to fig. 1, an image capturing apparatus according to a first preferred embodiment of the present invention includes a camera lens 1, a camera module 3, and a protective housing 2 for protecting the camera lens 1 and the camera module 3.

The image pickup lens 1 can control the intensity of light reaching the photosensitive layer, the magnification of an image, the range of a viewing angle, the clear range of an image, and the like. Depending on the object to be photographed, a wide-angle lens, a wide-focus lens, a catadioptric lens, an intermediate-focus lens, a telephoto lens, a zoom lens, a macro lens, a micro lens, and the like can be used as the image pickup lens 1 of the image photographing apparatus of the present invention.

Since the image capturing apparatus of the present invention is specifically used for capturing images of the contact surface of certain specific organs (e.g., anus, vagina, etc.) in the human body, which can be contracted and enlarged and are normally in a closed state, it is preferable to use a micro-focus lens as the image capturing lens 1 of the image capturing apparatus in the present preferred embodiment. Of course, it is obvious to those skilled in the art that other types of lenses may be used as the imaging lens 1 of the image capturing apparatus as long as they can meet the capturing requirements.

The imaging lens 1 of the present invention has a shape that is adapted to macro photography requirements, for example, a circular arc-shaped outer surface a that protrudes outward, so as to expand the shooting range of the imaging lens 1 as much as possible. In the preferred embodiment, the arc segment constituting the arc-shaped outer surface a forms an angle of 90 ° or less with respect to an imaginary axis passing through the focal point of the imaging lens 1, that is, the arc segment constituting the arc-shaped outer surface a is a semicircle. More preferably, the arc segments constituting the arc-shaped outer surface a form an angle of less than or equal to 60 ° with respect to an imaginary axis passing through the focal point of the lens. Most preferably, the arc segments constituting the arc-shaped outer surface a form an angle of less than or equal to 45 ° with respect to an imaginary axis passing through the focal point of the lens.

Of course, the imaging lens 1 may have other suitable shapes, such as a rod shape.

The camera module (CCM)3 is a well-known integrated unit in the technical field, and is widely applied to smart phones, security equipment and building intercom equipment. Generally, a camera module is composed of an infrared filter, an image sensor, a Digital Signal Processor (DSP), and a flexible circuit board (FPC), which are well known to those skilled in the art.

In the preferred embodiment, the camera module 3 is associated with the camera lens 1 to perform image capturing and signal processing. It should be noted that the term "associated" in the present invention not only means various association means available in the art such as connection, welding, molding, etc., but also includes various combination means for including the camera lens 1 in the camera module 3, and these modifications should fall within the protection scope of the present invention.

Therefore, in some embodiments, the camera module 3 and the camera lens 1 may be connected by wires, wireless signals, electrical signals, and the like. In another alternative embodiment, the camera module 3 and the camera lens 1 may be integrated, as long as the outer surface a of the camera lens 1 is ensured to be in a shape suitable for macro shooting. Such variations are intended to fall within the scope of the invention.

The imaging lens 1 and the imaging module 3 are built in the protective case 2. The protective casing 2 is made of a transparent material so as to protect the camera lens 1 and the camera module 3 therein.

The transparent material constituting the protective casing 2 is well known to those skilled in the art and may be, for example, silicate glass, tempered glass, plexiglass or polycarbonate plastic. It is known that silicate glass has high heat resistance, but is highly brittle and easily broken; organic glass or polycarbonate plastic is cheap, but is easy to corrode; the toughened glass can form a multilayer composite transparent material, but the cost is higher. Those skilled in the art can select suitable materials for forming the protective housing 2 according to different test conditions, and all available materials should fall within the scope of the present invention.

The protective casing 2 is substantially in the form of a cylindrical sleeve, but is formed as an outwardly projecting outer surface B at one end that accommodates the photographic lens 1. In the preferred embodiment, the outwardly protruding outer surface B is a circular arc or rod-shaped outer surface, and the shape of the outer surface B is consistent with the shape of the circular arc or rod-shaped outer surface a of the camera lens 1, so that the camera lens 1 can be attached to the inner wall of the protective housing 2. It should be noted that the term "the shapes coincide with each other" means that the distances between the circular arc-shaped or bar-shaped outer surface a of the imaging lens 1 and the corresponding points on the circular arc-shaped or bar-shaped outer surface B of the protective housing 2 are equal, that is, the radians of both outer surfaces are the same. Therefore, the micro focus lens as the imaging lens 1 can ensure that each point on the outer surface of the protective case 2 can obtain the clearest image in the imaging module 3 and display the image in a high definition mode.

The imaging lens 1 of the present invention has a circular arc-shaped or bar-shaped outer surface a protruding outward to expand the shooting range of the imaging lens 1 as much as possible.

Compared with the first preferred embodiment, the image capturing apparatus according to the second preferred embodiment adds the image signal converter 4, so that the image obtained by the camera module 3 can be converted into a digital signal and transmitted and displayed in the external terminal device. Therefore, the image signal converter 4 is associated with the image pickup module 3 and the image pickup lens 1, and performs image pickup, signal processing, conversion, transmission, and the like together. Therefore, in some embodiments, the image signal converter 4, the camera module 3, and the camera lens 1 may be connected by wires, wireless signals, electrical signals, or the like. In yet another alternative embodiment, the image signal converter 4 may be integrated with the image pickup module 3 and the image pickup lens 1 as long as the outer surface a of the image pickup lens 1 is ensured to be in a circular arc shape or a bar shape. Such variations are intended to fall within the scope of the invention.

The imaging lens 1, the imaging module 3, and the image signal converter 4 are built in the protective case 2. The protective casing 2 is made of a transparent material so as to protect the camera lens 1, the camera module 3 and the image signal converter 4 therein.

The protective casing 2 is substantially in the form of a cylindrical sleeve, as in the first preferred embodiment, but is formed as an outwardly projecting outer surface B at the end that houses the photographic lens 1. In the preferred embodiment, the outwardly protruding outer surface B is a circular arc or bar-shaped outer surface, and the shape of the outwardly protruding outer surface B completely conforms to the shape of the circular arc or bar-shaped outer surface a of the camera lens 1, so that the camera lens 1 can be attached to the inner wall of the protective housing 2, and each point on the outer surface of the protective housing 2 can obtain the clearest image in the camera module 3.

In addition, a light emitting element 5 for illumination is embedded on the inner wall of the protective casing 2, and the light emitting element 5 can emit light when the camera lens 1, the camera module 3 and the image signal converter 4 work, so as to provide better shooting environment.

The light emitting element 5 is preferably a Light Emitting Diode (LED) having a color temperature close to natural light. Of course, it will be readily understood by those skilled in the art that other known light emitting elements may be used, and such modifications are intended to fall within the scope of the present invention.

The camera lens 1, the camera module 3 and the image signal converter 4 are built in the protective housing 2, and the light emitting element 5 is embedded on the inner wall of the protective housing 2. The protective casing 2 is made of a transparent material so as to protect the camera lens 1, the camera module 3 and the image signal converter 4 therein and not to shield light emitted from the light emitting element 5.

The protective casing 2 is substantially in the form of a cylindrical sleeve, as in the first preferred embodiment, but is formed as an outwardly projecting outer surface B at the end that houses the photographic lens 1. In the preferred embodiment, the outwardly protruding outer surface B is a circular arc or bar-shaped outer surface, and the shape of the outwardly protruding outer surface B completely conforms to the shape of the circular arc or bar-shaped outer surface a of the camera lens 1, so that the camera lens 1 can be attached to the inner wall of the protective housing 2. The light emitting elements 5 are preferably embedded at both sides of the arc segment constituting the outer surface a.
