JP 2000-184013 (paragraph 0002, FIG. 2)

By the way, there is a technique for processing the periphery of the photographing unit of the camera into a special shape so that a lens can be attached to such a camera. However, such technology requires processing the periphery of the shooting unit into a special shape, which increases the price of the camera, and the lens is dedicated to each camera, so cameras of different models There was a problem that it could not be reused between.
For such a camera, there is also a technique for attaching a lens to the camera using a special adapter. However, such technology, it is necessary to process the imaging unit around the special shape, a camera or a problem that would cause a high cost, since the number of parts is increased, facilitating complex removal structure In addition, there was a problem that it was inconvenient to carry.
Furthermore, some cameras do not have a cover for protecting the photographing unit. Since the photographing part of such a camera is exposed, there is a problem that it is easily scratched.
The present invention solves these problems .

In order to solve the above-described problems, a lens according to the present invention is characterized in that a lens main body that transmits light is attached to a photographing unit of a photographing machine by a frictional force generated between the photographing unit of the photographing machine . Thereby, this invention can attach a lens main-body part to the imaging | photography part of an imaging device irrespective of the shape of an imaging device.

In the lens according to the present invention, for example, a retraction part is provided in the photographing part of the photographing machine, and the lens main body part is formed with a fitting part that can be fitted to the retreating part provided in the photographing part of the photographing machine. You may be made to do. In this case, in particular, it is preferable that the fitting portions are provided with different sizes on both surfaces of the lens main body portion so that the fitting portions can be fitted to the retracted portions having different sizes.

Since this invention can attach a lens body part to a photographing part of a photographing machine regardless of the shape of the photographing machine, it does not process the photographing part of the camera into a special shape between cameras of different models. This has the effect that the lens body can be reused. In addition, for a camera that does not have a cover for protecting the photographing unit, the camera can be used as a cover that can be reused (that is, disposable) to protect the photographing unit. Further, for example, there is an effect that it can be fitted to two kinds of retracted portions having different sizes, such as the diameter of the specification of the company A and the diameter of the specification of the company B.

  The present invention is a pinhole type camera mounted on an information terminal such as a mobile phone, a notebook PC or a PDA (including an electronic notebook), or a handy type such as an instant camera or a digital camera. The present invention can be applied to other cameras or projectors.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings, taking a camera mounted on an information terminal as an example. Each figure is shown only schematically to the extent that the present invention can be understood. Moreover, in each figure, about the common element, the same code | symbol is attached | subjected and description is abbreviate | omitted.

<First Embodiment>
The lens according to the first embodiment is attached to the photographing unit of the camera described above by adhesive force. The first embodiment will be described below with reference to FIGS. 1 is a diagram showing an application example of the lens according to the first embodiment, FIG. 2 is a perspective view of the lens according to the first embodiment, and FIG. 3 is a result of attaching the lens according to the present invention. FIG. 4 is a diagram showing a method of changing the focal position, and FIG. 5 is a diagram showing a method of changing the angle of view.

  As shown in FIG. 1, a camera mounted on an information terminal 11 (a mobile phone in the example of FIG. 1) such as a mobile phone, a notebook PC, a PDA (including an electronic notebook), an instant camera, a digital camera, etc. The handheld camera 13 has a photographing unit 15 that captures an image inside. The imaging unit 15 includes an imaging element (not shown) that forms an image inside, a lens 17, and the like, and a cover 19 that protects them outside. The cover 19 is made of a material such as transparent glass or plastic, and can transmit light. This cover 19 can be eliminated. In addition, the information terminal 11 and the handheld camera 13 are preferably formed so that a portion in contact with the lens is flat so that the lens according to the present invention is suitably attached.

  Hereinafter, the case of the information terminal 11 will be described, but the same applies to a digital camera.

  The lens according to the present invention includes a lens body 21 that transmits light and a pressure-sensitive adhesive member 23, which are referred to as a so-called crystalline lens. The lens body 21 is made of a material such as glass or plastic having transparency, and guides an external scene (for example, an image like the subject 27) to an imaging element (not shown) inside the information terminal 11. . The lens body 21 may be colored as will be described later. In addition, the lens body 21 may be a so-called lens having a refractive index of 0. The adhesive member 23 is obtained by applying an adhesive to a sheet-like medium. The adhesive member 23 functions as an attaching means for attaching the lens body 21 to the photographing unit 15 with adhesive force, and is attached to the cover 19 of the photographing unit 15 (however, when the cover 19 is excluded from the photographing unit 15). Is attached to the lens 17 and its surrounding casing). The adhesive member 23 is configured to be detachable from the photographing unit 15 of the photographing machine and to be detachable from the lens main body unit 21. The sheet-like medium is made of, for example, a plastic material such as polyurethane or paper. It is desirable that the sheet-like medium of the adhesive member 23 has elasticity in consideration of ease of attachment to the photographing unit 15. Thereby, even when there is a step in the photographing unit 15, it is possible to absorb and attach it. In addition, this makes it possible to absorb the arc of the lens body 21, so that it can be attached to various types of lens body 21. Note that the adhesive member 23 can be formed by sticking adhesive tape to both surfaces of the sheet-like medium without making the sheet-like medium itself sticky. It is also possible to form the adhesive by processing it into a sheet without using a sheet-like medium.

  Two specific configurations of such a lens are shown in FIG. FIG. 2A shows a first configuration example of the lens according to the first embodiment, and FIG. 2B shows a second configuration example. The adhesive member 23 according to the first configuration example shown in FIG. 2A is made of a transparent material so that light can be transmitted, and has substantially the same shape / size as the lens body 21. ing. On the other hand, the adhesive member 23 according to the second configuration example shown in FIG. 2B is configured to have substantially the same shape and the same size as the lens main body 21, and is incorporated in the photographing unit 15 on the inner side. A hole 25 is provided to prevent light from being blocked. Note that the adhesive member 23 according to the second configuration example shown in FIG. 2B is not required to be made of a transparent material because the hole 25 for transmitting light is provided. Instead, it is desirable that the hole 25 has a size larger than that in which the adhesive member 23 does not appear in the image captured by the camera.

  FIG. 3 shows the effect of attaching such a lens. FIG. 3A shows an example when the lens is not attached, and FIG. 3B shows an example when the lens is attached. The example of FIG. 3B shows a third configuration example different from the first and second configuration examples shown in FIGS. 2A and 2B. That is, in the third configuration example, the adhesive member 23 is formed larger than the lens main body portion 21, and a hole 25 for fitting the lens main body portion 21 is provided inside thereof, and only the surface facing the cover 19 is adhesive. It is something that has sex.

  In the example of FIG. 3A, the focus position of the lens 17 exists farther than the subject 27, and the focus is not on the subject 27. In such a state, an image formed on an imaging element (not shown) is a so-called out-of-focus image with a sharp outline.

  On the other hand, in the example of FIG. 3B, the focal position exists on the subject 27 by attaching the lens according to the present invention (the lens main body 21 and the adhesive member 23 in the first embodiment) to the cover 19. The focus is on the subject 27. In such a state, an image formed on an imaging element (not shown) has a sharp outline. In the example of FIG. 3B, a convex so-called close-up lens for reducing the focal position is used. When the focal position is increased, a so-called telephoto lens having a concave shape is used.

  FIG. 4 shows a method for changing the focal position using such a lens. FIG. 4A shows an example in which the focal position is changed by using lenses having different thicknesses, and FIG. 4B shows an example in which the focal position is changed by changing the number of the adhesive members 23. Yes. The adhesive member 23 shown in FIGS. 4 (a) and 4 (b) is the same as that shown in FIG. 2 (b). Further, the distance from the lens 17 to the subject 27 in FIGS. 4A and 4B is the same.

  In the example shown in FIG. 4A, a lens having a specific magnification is selected from a plurality of lens main bodies 21 having a specific magnification, and the focal point is thus focused on the subject 27.

  On the other hand, in the example shown in FIG. 4B, the lens body 21 having a thickness smaller than that of the lens body 21 in the example shown in FIG. 4A is used. Instead, the cover 19 and the lens body are used. An adhesive member 23 is placed between 21 and 21. Thereby, the distance between the lens 17 and the lens body 21 is made larger than the distance in the example shown in FIG. Note that the same effect can be obtained by changing the thickness of the adhesive member 23 instead of arranging the adhesive member 23 in an overlapping manner.

  In the example shown in FIG. 4B, the magnification can be increased if the distance between the lens 17 and the lens body 21 is increased, and can be decreased if the distance is decreased. Therefore, the photographer can focus on the subject 27 by setting the number of the adhesive members 23 to an arbitrary number. Therefore, in the example shown in FIG. 4B, it is not necessary to prepare a plurality of lenses having a specific magnification as shown in FIG. 4A, and the adhesive member 23 is manufactured at a lower cost than the lens body 21. Therefore, it can be provided at a lower cost than the example shown in FIG.

  Thus, in the first embodiment, the photographer can arbitrarily change the in-focus position. In particular, this is effective for the following reasons, for example, when close-up information such as characters is taken at a short distance.

  That is, in recent years, with the spread of communication technologies such as the Internet, it has been required to import information such as texts described in books, reports, information boards, newspaper articles, maps, etc. into the information terminal 11. . However, the conventional camera mounted on the information terminal 11 is set so that a person or a landscape is an object to be photographed, and cannot focus on a short distance of about several centimeters. In other words, if you try to acquire an image that is in focus for the entire character, you can acquire only a small image that cannot be recognized by humans. Conversely, if you try to acquire an image that is large enough to be recognized, the image is out of focus. Only images could be acquired. In this way, text and other information captured from books with a conventional camera becomes an image that is too small to be recognized by humans or is out of focus, so it can be used effectively even if saved as an electronic file. I couldn't. In addition, if information such as text is transmitted to a remote place, it cannot be used with a conventional camera with a fixed focal length, so the photographer can type text or scan It was necessary to convert the data into a viewable data and transmit it, for example, by reading the file. Therefore, time and labor for data conversion have occurred.

  For example, in a telemedicine system, even if a doctor tries to examine an affected part of a patient who is far away with a camera connected to a personal computer or the like, the affected part cannot be seen clearly and cannot be treated satisfactorily. .

  In the first embodiment, it is possible to acquire an image that is in a recognizable size and in focus with a simple operation, and thus these problems can be solved. Therefore, it is particularly effective in the above case.

  Next, a method of changing the angle of view using such a lens is shown in FIG. FIG. 5A shows an example when the lens is not attached, and FIG. 5B shows an example when the lens is attached.

  In the example of FIG. 5A, the angle of view of the lens 17 is a standard positive diagonal.

  On the other hand, in the example of FIG. 5B, the angle of view becomes a wide angle by attaching the lens according to the present invention (the lens body 21 and the adhesive member 23 in the first embodiment) to the cover 19. Yes. In the example of FIG. 5B, a so-called wide-angle lens having a concave shape for widening the angle of view is used. In order to narrow the angle of view, a convex so-called narrow angle lens is used.

  Thus, in the first embodiment, the photographer can arbitrarily change the angle of view.

  As described above, in the first embodiment, the photographer can focus on a short distance or change the angle of view with a simple operation. Moreover, since it covers the photographing unit 15 of the camera, it is possible to prevent the periphery of the photographing unit 15 from being damaged, and it can be used as a cover for protecting the photographing unit 15.

<Second Embodiment>

The second embodiment will be described below with reference to FIG. FIG. 6 is a cross-sectional view of a lens according to the second embodiment.

  For example, as shown in FIG. 6, a suction cup 29 as an attachment means is attached to the lens body 21. The suction cup 29 is made of a flexible member such as rubber. The lens is attached to the photographing unit of the camera by the photographer pressing the suction cup 29 against the flat area on the cover 19 and pressing it. At this time, the air inside the suction cup 29 is discharged to the outside, whereby the internal pressure becomes lower than the external pressure, and the suction cup 29 is joined to the cover 19. The suction cup 29 may be fixed to the lens body 21 so that it cannot be removed from the lens body 21 or may be removable. In the example shown in FIG. 6, the lens is attached to the photographing unit 15 of the camera by the suction cup 29, but a magnet may be used instead of the suction cup 29.

  As described above, in the second embodiment, as in the first embodiment, the photographer can focus on a short distance or change the angle of view with a simple operation. Moreover, since it covers the photographing unit 15 of the camera, it is possible to prevent the periphery of the photographing unit 15 from being damaged, and it can be used as a cover for protecting the photographing unit 15.

The color near the outer periphery of is darker. With such a configuration, the lens according to the fifth modification can capture an image in which the vicinity of the center is clear and the vicinity of the outer periphery is unclear (that is, an image in which the periphery is blurred).

  As shown in FIG. 16B, the lens according to the sixth modified example has a lens body portion 21 provided with a V-shaped groove 227. With such a configuration, the lens according to the sixth modification can capture an image divided into a plurality of sections.

  In the lens according to the seventh modification, as shown in FIG. 16C, the lens main body portion 21 is subjected to a plurality of cuts having an arbitrary shape. With such a configuration, the lens according to the seventh modification can capture an irregularly reflected image (that is, an image in which the direction in which the subject appears is different for each part of the image).

  As described above, the fifth to seventh modified examples can shoot images with any special effect according to the purpose of shooting, the photographer's preference, and the like.

(Eighth modification)
The lens according to the eighth modification is for photographing an image with an arbitrary special effect using filters subjected to various processes. Hereinafter, an eighth modification will be described with reference to FIGS. FIGS. 17 and 18 are views showing an eighth modification of the lens.

  The lens according to the eighth modification is, for example, a combination of a lens body 21 and a filter 229 that has been subjected to predetermined processing, as shown in FIG. 17A or 17B. is there. FIG. 17A shows an example in which the filter 229 is arranged under the lens body 21, and FIG. 17B shows an example in which the filter 229 is arranged on the lens body 21. The lens according to the eighth modification is attached to the photographing unit 15 of the camera by the adhesive member 23 or other attachment means.

  The filter 229 is formed in a thin film shape using, for example, acrylic, vinyl chloride, polyvinyl chloride, polypropylene, polycarbonate, or the like.

  In addition, the filter 229 is subjected to various processes for photographing an image having an arbitrary special effect according to the purpose of photographing or the photographer's preference. As an example of processing, for example, coloring processing such as the lens body 21 according to the fourth modification or the fifth modification, or the V-shaped groove like the lens body 21 according to the sixth modification. There are a forming process, a forming process of a plurality of cuts in an arbitrary shape, such as the lens body 21 according to the seventh modification. In addition, for example, there is a process that provides a characteristic of transmitting light of a specific wavelength such as ultraviolet light or infrared light, a characteristic of enhancing light of a specific wavelength, a characteristic of blocking light of a specific wavelength, and the like.

  In the lens according to the eighth modification, for example, as shown in FIG. 18A, a plurality of lens main body portions 21 and filters 229 may be combined. FIG. 18A shows an example in which the filter 229 is disposed under the plurality of lens main body portions 21, but the filter 229 may be disposed on or between the plurality of lens main body portions 21. Each lens body 21 and the filter 229 are fixed to each other by the adhesive member 23 or other attachment means.

  Further, in the lens according to the eighth modification, for example, as shown in FIG. 18C, the lens body 21, the filter 229, and a jig 223 formed with a predetermined thickness may be combined. . In the example shown in FIG. 18C, the lens main body 21 and the filter 229 are one by one, but may be plural. Further, the filter 229 is disposed below the lens body 21, but may be disposed above the lens body 21. The filter 229 may be disposed between the lens main bodies 21 when there are a plurality of lens main bodies 21.

  In the example shown in FIG. 18B and FIG. 18C, the adhesive member 23 or the jig 223 is formed of a single member, but a plurality of members are stacked to form the adhesive member 23 or the jig 223. The same effect can be obtained. Further, in the example shown in FIGS. 18B and 18C, the lens has an arbitrary thickness secured by the adhesive member 23 or the jig 223, so that the lens can be constructed robustly and the filter When 229 is a thin film-like material, the nail or the like is easily caught and can be easily peeled off.

  When a plurality of lens main bodies 21 are used, wide-angle shooting can be performed when, for example, a lens close to the photographing unit 15 of the camera is a convex lens and a far lens is a concave lens. Telephoto shooting can be performed by using a concave lens as the lens closer to the camera 15 and a convex lens as the far side.

  As described above, the eighth modification can capture an image with an arbitrary special effect. In particular, the example shown in FIG. 18 is suitable for telephoto shooting, close-up shooting, and the like because the magnification can be adjusted to an arbitrary size.

  As shown in FIG. 39A, the lens according to the twenty-third modification is provided with one or more notches 273 in the lens main body 21 and, for example, an LED 275 for emitting light. Is. As shown in FIG. 39B, the lens according to the twenty-third modification includes a power supply unit 269 in which a battery BOX (not shown) for storing a battery is incorporated, and the LED 275 is connected via a wiring 277. Supply power to In the lens according to the twenty-third modification, the cover 271 protects the wiring 277 that connects the power supply unit 269 and the LED 275.

  As described above, the lenses according to the twenty-first to twenty-third modifications can be photographed while irradiating the subject with light, and thus are suitable for close-ups that tend to be insufficient in light quantity.

(24th modification)
The lens according to the twenty-fourth modified example adheres to a display unit of an information terminal such as a mobile phone, a notebook PC or a PDA (including an electronic notebook), or a display unit of a handy camera such as an instant camera or a digital camera. It is designed to be attached by force. Below, the 24th modification is demonstrated using FIGS. 40-43. FIG. 40 shows a lens mounting example according to the twenty-fourth modification, FIG. 41 shows a configuration example of the lens according to the twenty-fourth modification, and FIGS. 42 and 43 are enlarged views of a part of the lens. An example of the configuration is shown.

  For example, as shown in FIG. 40, the handheld camera 13 such as a digital camera includes a shutter button 151, a button 153 for setting operations such as shooting and reproduction, a display unit 155, and the like. In addition, a protrusion 157 is provided on the outer periphery of the display unit 155 to prevent the display unit 155 from colliding with any object. The lens 22 according to the twenty-fourth modification is attached to the protrusion 157 of the camera 13.

  The lens 22 is made of a transparent material so that light can be transmitted, and is formed in substantially the same shape / size as the protrusion 157 of the camera 13. The lens 22 is applied with a transparent adhesive at a position corresponding to the projection 157 or a transparent adhesive member is attached so that the lens 22 can be attached to the projection 157 of the camera 13. It should be noted that the lens 22 is formed to have a certain level of hardness (for example, a hardness that slightly bends when the end is pinched) so that the lens 22 can be easily attached to the protrusion 157 of the camera 13. preferable.

  For example, as illustrated in FIG. 41, the lens 22 is formed as an assembly of sheet-like lenses including a plurality of sections 22-1. The section 22-1 is formed as an assembly of linear Fresnel lenses or cross linear Fresnel lenses.

  In the linear Fresnel lens, a refracting portion for refracting light is arranged in a band shape. As shown in the perspective view of FIG. 42 (a) and the side view of FIG. 42 (b), the structure is formed so that the rear surface of the lens and a horizontal region are formed in the central portion and deviated from the center. A refracting portion for refracting light at a predetermined interval is formed in a band shape in the portion. The linear Fresnel lens provided with the belt-like refracting portions parallel to the left and right guides light as indicated by arrows in FIG. That is, the linear Fresnel lens straightens the light that has entered the center of the lens, and the light that has entered the part that is off the center of the lens so that the left and right are parallel and the light that has entered the center of the lens. Refract so that they intersect at almost the same point.

  In the cross linear Fresnel lens, refractive portions for refracting light are arranged in a lattice shape. As shown in FIG. 43, the structure is such that two linear Fresnel lenses 22-1a and 22-1b joined back to back are shifted in phase by 90 °.

  The linear Fresnel lens or the cross linear Fresnel lens has the following characteristics. That is, the lens 22 can be formed in a sheet shape. Further, the enlargement ratio of the central portion and the portion deviating from the center can be made substantially the same. However, with a single linear Fresnel lens or cross linear Fresnel lens, when the focal length to the object to be magnified is short, the lens diameter becomes small, and a lens with a desired area can be formed. Can not. Therefore, in the twenty-fourth modified example, each section 22-1 is formed by a plurality of small-diameter linear Fresnel lenses or cross linear Fresnel lenses having a square or rectangular shape, and the sections 22-1 are connected in a bowl shape or a lattice shape. By combining them, a lens 22 having a desired area is formed. In this way, the lens 22 is formed as a lens having a large area and a short focal distance to the object.

  One linear Fresnel lens or cross linear Fresnel lens forms each section 22-1. The sections 22-1 are arranged vertically and horizontally to form the lens 22. In addition, the arrangement | sequence of each division 22-1 may become the same direction, and the phase may be shifted 90 degree | times between adjacent divisions 22-1. The lens 22 according to the twenty-fourth modified example formed as described above can solve the following problems existing in a lens attached to a conventional display unit.

  That is, the lens attached to the conventional display unit has a complicated structure because it is attached with a dedicated adapter or screw. In addition, when the lens is a convex lens, a certain thickness or more is required. Therefore, when a device (for example, a mobile phone or a notebook PC) is foldable, the device cannot be folded and attached to the display unit. I can't. In addition, a single focus lens (that is, a lens that focuses on a single point in the center of the lens) enlarges the central portion of the screen greatly, and the portion outside the center has a small enlargement ratio, so the size of the characters becomes uneven. . The lens 22 according to the twenty-fourth modification can solve such a problem. That is, it can be attached to the display unit with a simple structure using an adhesive or an adhesive member. Moreover, since it can form in a sheet form, even if it attaches to the display part of a foldable apparatus, an apparatus can be folded. Further, since the enlargement ratio of the central portion of the screen and the portion off the center can be made substantially the same, the size of the characters can be made substantially uniform.

  In addition, since the lens 22 is attached to the protrusion 157 of the camera 13, the lens 22 is attached away from the display unit 155 of the camera. Therefore, the display unit 155 can be protected so as not to collide with any object.

  The lens 22 is formed as an aggregate of a plurality of sections 22-1. For this reason, the lens 22 can be formed in accordance with the display size such as the number of pixels and the number of characters of the display portion, so that an optimal enlarged display can be performed.

  The lens 22 can also be formed as a lens having no degree.

<Hole shape>
The hole 201 formed in the lens shown in FIGS. 22 and 25 to 33 can be deformed as shown in FIG. FIG. 44 is a diagram showing another shape example of the hole, and shows an example in which the hole 201 is transformed into a hook-type hole 201a.

  22 and 25 to 33 show an example in which the string 203 is inserted into the hole 201 from one end of the string 203, but in FIG. 44, the string 203 is pushed from the opening portion of the hook. An example is shown. The present invention includes such a configuration.

<Joint strength of mounting means>
Hereinafter, the joining force of the attaching means will be described with reference to FIG. FIG. 45 is a diagram showing the relationship of the joining means. The term “bonding force” as used herein is a general term for the adhesive force in the first embodiment, the adsorption force in the second embodiment, and the like.

  In FIG. 45, the bonding force of the adhesive member 23 on the camera side surface 49 is weaker than that of the lens body side surface 51. Thus, the photographer can reliably remove the entire lens when removing the lens from the photographing unit of the camera. That is, it is possible to eliminate the case where only the lens main body portion 21 is removed and the adhesive member 23 is left in the photographing portion of the camera.
