Abstract
The invention provides a circumscribed microlens lens which is adapted to a digital camera. The digital camera is provided with a zoom lens and a maximum field angle; and the circumscribed microlens device comprises an adapter, a microlens and a light source. One end of the adapter is connected to the digital camera. The microlens is connected with the other end of the adapter and optically connected with the zoom lens; and the microlens is provided with a diaphragm. The light source is arranged between the adapter and the microlens and used for sending lights outwards from the microlens, wherein the diaphragm of the microlens at least can allow the maximum visual angle of the digital camera to pass through.
Description
Technical field
The present invention relates to a kind of optical camera lens device, relate in particular to a kind of microlens device that is external in digital camera.
Background technology
Digital camera has promptly to clap promptly to be seen, and the characteristics that are easy to export to computer-related devices, makes it replace the camera that tradition needs to use egative film rapidly, becomes the main flow in camera market now.
The highest enlargement ratio of general digital camera is several times to ten several times mostly, only can be used to take general scenery, is difficult to the object surfaces micromechanism is taken.On the other hand, general commonly used optical microscopy device volumes such as microscope are excessive, it is constant to carry, and also cause the restriction in the application.
For addressing the above problem, generally speaking can a kind of Circumscribed microlens with high magnification enlarging function be installed on the above-mentioned commercially available digital camera, just can obtain a kind of high magnification camera head simple and easy to carry.
Yet reality when an object is taken, often need make its camera lens itself very near this object with above-mentioned Circumscribed microlens, has stopped that on the contrary extraneous light arrives this object, and has made this object brightness deficiency to take.In addition, because the microlens of circumscribed and digital camera originally in can't well arranging in pairs or groups down, often cause the periphery of captured image to produce black surround, make reality can take area and significantly reduce.
Summary of the invention
A purpose of the present invention is to provide a kind of Circumscribed microlens, not only can provide the enough brightness of object for shooting, and can not produce black surround.
For achieving the above object; The present invention provides a kind of Circumscribed microlens device, is used to transfer in a digital camera, and this digital camera has a zoom lens and an absolute visual field angle; This Circumscribed microlens device comprises an adapter, a microlens, and a light source.This adapter one end is connected on this digital camera.This microlens connects the other end of this adapter, and this zoom lens of optics connection, and this microlens has a diaphragm.This light source is arranged between this adapter and this microlens, and in order to outwards to emit beam via this microlens, wherein, the diaphragm of this microlens can supply the absolute visual field angle of this digital camera to pass through at least.
The present invention is outwards emitted beam via this microlens by this light source, to supply the enough light of this object, supplies the user that this object is clearly taken.And can supply the absolute visual field angle of this digital camera to pass through at least by the diaphragm that limits this microlens, to avoid the generation of black surround.Describe the present invention below in conjunction with accompanying drawing and specific embodiment, but not as to qualification of the present invention.

Embodiment
Relevant technology contents of the present invention and detailed description cooperate graphic explanation following:
Consult Fig. 1 and Fig. 2, be the preferred embodiment of Circumscribed microlens device 10 of the present invention, be used to transfer in a digital camera 20.This digital camera 20 has a fuselage 21 and by these fuselage 21 outward extending zoom lens 22.This digital camera 20 has an absolute visual field angle by this fuselage 21 and 22 common decisions of this zoom lens.
This Circumscribed microlens device 10 consists predominantly of an adapter 11, a microlens 12, and a light source 13.One end of this adapter 11 is connected on the fuselage 21 of this digital camera 20.Specifically, this fuselage 21 locates to be formed with a junction 211 around contiguous this zoom lens 22.11 of this adapters have the through hole 110 that this zoom lens 22 of confession runs through, and this adapter 11 is connected on this connecting portion 211 with its through hole 110.
This microlens 12 is in order to amplify image, and it passes through the other end that exntension tubs 16 connect these adapters 11, and is connected with these zoom lens 22 optics.Specifically, this microlens 12 comprises a lens barrel 121 and at least one and is located in this lens barrel 121 and the eyeglass 122 that is connected with these zoom lens 22 optics.These exntension tubs 16 are in order to longer in the length of this zoom lens 22, and protrude in this adapter 11 ccontaining this zoom lens 22 when outer.In addition, also comprise an eyeglass ring 14 between these exntension tubs 16 and this microlens 12, and the eyeglass 15 that is arranged in this eyeglass ring 14.
This light source 13 is arranged between this eyeglass ring 14 and this microlens 12, in order to outwards to emit beam via this microlens 12.This light source 13 comprises a ring-like circuit board 131 and a plurality of compartment of terrain is arranged at the luminescence component 132 on this ring-like circuit board 131.In the present embodiment, those luminescence components 132 are surface-mounting LED.In addition, Circumscribed microlens 10 of the present invention also comprises the battery module of being located in this adapter 11 17, in order to this light source 13 is supplied power.
Outwards emit beam via this microlens 12 by this light source 13; Even if this microlens 12 when taking near thing and object distance too near; So that stopped that extraneous light arrives this object, this light source 13 can be supplied the enough light of this object, supplies the user that this object is clearly taken.
In addition, as shown in Figure 2, this digital camera 20 has one by image sensor 23 outward extending absolute visual field angles, and the diaphragm of a predetermined bore.The diaphragm of this microlens 12 can supply not passing through of blocked of this absolute visual field angle at least.In the present embodiment, the aperture of this diaphragm is determined by the bore of this eyeglass 122, during actual enforcement, does not then limit with this, can be edge, the framework of arbitrary optical module in this microlens 12, or the special barrier with holes that is provided with.
Certainly; The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
