During micro distance photography, the camera can focus the light emitted by the light source at the object position through the light collecting device and moves the light collecting device along the direction near or far from the light source, so as to change convergence degree of the light, thereby facilitating the object with best illuminance, overcoming defect of insufficient object illuminance led in by main body shading natural light during micro distance photography, further improving photography quality.
Description
Technical field
The present invention relates to a kind of camera, relate in particular to a kind of camera with microshot function.
Background technology
In recent years, the digital camera of many new releases, camera cell phone etc. all have the function of microshot.Microshot is a kind of in-plant, style of shooting that enlargement factor is high.The general image that can take near the object actual size just belongs to microshot.The purpose of microshot is to make every effort to the details that naked eyes do not see is obtained showing more clearly.
When microshot, the distance of camera and object is generally 3～10cm, have in addition have only 1～2cm.Because camera and object distance is too little during microshot, environment light source regular meeting is blocked by camera body, makes that the object light is not enough, causes the shooting quality to descend, and therefore, when microshot, the auxiliary lighting apparatus of camera is very important for taking quality.Light emitting diode commonly used carries out floor light in the present camera, but because light emitting diode is a pointolite, its emergent light is what disperse, and is still undesirable to the illumination of object.
In view of this, be necessary to provide a kind of camera that improves the microshot quality.
Summary of the invention
To a kind of camera that improves the microshot quality be described with specific embodiment below.
A kind of camera, be used for object is carried out imaging, this camera comprises that a body and is arranged on the auxiliary lighting apparatus on this body, described body has an accepting hole, wherein, this auxiliary lighting apparatus comprises that one is arranged on a light source and the light collecting device in the described accepting hole, this light collecting device can along near or move away from the direction of described light source, be used to assemble the light that this light emitted goes out, with the illumination object.
Compared with prior art, described camera is when carrying out microshot, the light-ray condensing that can light emitted be gone out by described light collecting device is in the object place, and can with this light collecting device along near or move away from the direction of light source, to change the convergence degree of described light, thereby make object obtain optimal illumination, body blocks natural light and causes object illumination defect of insufficient when having overcome microshot, and then can improve the shooting quality.
Description of drawings
Fig. 1 is the decomposition texture synoptic diagram of the camera that provides of the embodiment of the invention.
Fig. 2 is the assembling synoptic diagram of camera shown in Figure 1.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.
See also Fig. 1 and Fig. 2, the camera 100 that the embodiment of the invention provided, it comprises that a body 110 and is arranged on the auxiliary lighting apparatus 120 on this body 110.This camera 100 is used for object is carried out imaging.
Offer an accepting hole 112 on the described body 110, be used to accommodate described auxiliary lighting apparatus 120.This accepting hole 112 is generally blind hole, and it can be provided with internal thread 1122.Also be provided with a camera lens module 114 that is used for the object imaging on this body 110, this camera lens module 114 and described auxiliary lighting apparatus 120 adjacent the same sides that are arranged at described body 110.Certainly, be understandable that this body 110 also can comprise the sensitization module, the general spare part that camera had as image sensor etc.
Described auxiliary lighting apparatus 120 comprises a light source 122 and a light collecting device 124.This light source 122 is arranged in the accepting hole 112 of described body 110.This light collecting device 124 is housed in the described accepting hole 112, is used to assemble the light that described light source 122 is launched, with the illumination object.This light collecting device 124 can along near or move away from the direction of described light source 122, to change the degree of described convergence of rays, make object obtain optimal illumination.
Concrete, described light collecting device 124 comprises that one assembles lens combination 1242, one load bearing seats 1244, and a set collar 1246.This convergent lens group 1242 is used to assemble the light that described light source 122 is launched, and it can be single or multiple convex lens, also can be the combination of at least one convex lens and at least one concavees lens etc., as long as can assemble the light that described light source 122 is launched.In the present embodiment, this convergent lens group 1242 is convex lens.Described load bearing seat 1244 has a through hole 12442, is used to accommodate described convergent lens group 1242.This load bearing seat 1244 can be shapes such as hollow cylinder or hollow round platform, and in the present embodiment, this load bearing seat 1244 is a hollow cylinder.Described convergent lens group 1242 can be retained in the through hole 12442 of this load bearing seat 1244 by set collar 1246.Certainly, this convergent lens group 1242 also can directly be retained in the described through hole 12442 by a glue mode with ultraviolet glue, resene white glues etc.Preferably, described load bearing seat 1244 also is provided with external thread 12444, it can be meshed with the internal thread 1122 of described accepting hole 112 by external thread 12444, thereby driving described convergent lens group 1242 moves along the optical axis of this convergent lens group 1242 (among Fig. 1 shown in the dot-and-dash line) direction in this accepting hole 112, to change the distance between this convergent lens group 1242 and the described light source 122, and then change the convergence degree of described light, make object obtain optimal illumination.Certainly, be understandable that this load bearing seat 1244 also can match with described accepting hole 112 by other modes that is slidingly connected, as long as it can move with described convergent lens group 1242 optical axis direction along this convergent lens group 1242 in this accepting hole 112.
The camera 100 that present embodiment provided is when carrying out microshot, the light-ray condensing that convergent lens group 1242 that can be by described light collecting device 124 is launched light source 122 is in the object place, and can drive this convergent lens group 1242 optical axis direction along this convergent lens group 1242 in described accepting hole 112 by the described load bearing seat 1244 of drivings such as step motor or servo motor moves, change the distance between this convergent lens group 1242 and the described light source 122, to change the convergence degree of described light, thereby make object obtain optimal illumination, body blocks natural light and causes object illumination defect of insufficient when having overcome microshot, and then can improve the shooting quality.
Certainly, be understandable that this camera 100 is used for non-microshot when need not to embody the object details, when ambient light is not enough, also can make object obtain adequate illumination by the way, take quality to improve.
In addition, those skilled in the art also can do other and change in spirit of the present invention, as the fit system that changes load bearing seat 1244 and accepting hole 112 etc., as long as it does not depart from technique effect of the present invention and all can.The variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
