Abstract

The utility model relates to a lattice mirror inner repeated exposure structure without joint, which comprises a camera. A shadow mask is additionally arranged in a mirror (before a negative film of the camera), a contraposition sheet which is the same with the shadow mask is arranged on a viewing window, and the shadow mask is transparent window and has at least two lattices. Because the shadow mask is arranged before the negative film for taking a picture to expose repeatedly, the negative film is obtained and images a plurality of repeated exposure images, and the imaging mode causes an exposure cross connecting area to do not have joint between the lattices.

Description

The in-mirror repeat exposure-making structure of no seam lattice

The utility model relates to camera, but refers to a kind of camera of repeat exposure-making imaging especially.

The repeat exposure-making of commonly using is taken, system fixedly camera does the continuous shooting of B shutter (the B shutter promptly is a roll film and be not related to shutter and utilize each flashlamp to reach the multiple-exposure effect according to thing reflects not with black background, wherein black background system is not reflective), the multiple repeat exposure-making of the continuous flashing light of utilization that should take is continuously taken, though can reach the shooting effect of continuous action, but its uncomfortable outer bat and light background and reflective background is an one shortcoming.

Other has the repeat exposure-making mode of commonly using, consult shown in Figure 1, system is to add the mode of shade 2 again outside camera lens 1, right this mode is resolved down in the lens of camera lens 1, changed a lot of in the time of on imaging in egative film, and the cross-connecting area of its repeat exposure-making is enlarged, consult shown in Figure 2, the portrait 3 of this repeat exposure-making, its hand 4 enters cross-connecting area 5 (the narrow camera lens and the focusing distance of being decided by of this cross-connecting area field width of repeat exposure-making because of carelessness, might not and can't predict or learn by observation), so the imaging of this hand 4 will be blured and be influenced its photograph quality after shooting is finished, and be its another shortcoming.

Moreover, commonly using camera does not have the design of para position plate, can't make personage's accurate placement, so photographer is when taking, all only amount allows the cross-connecting area of personage away from repeat exposure-making, so that mortality reduces, yet because so allow the personage lean on the imaging of photograph edge, and central spaciousness makes the photograph sensation quite strange and unnatural, and conjestures with photographer entirely because there not being para position plate, fault rate is more, is its another shortcoming.

Person again, commonly use camera and install shade with shooting as repeat exposure-making with the camera lens front end, but camera lens has wide-angle and full length shot, it is focused, and difference is very big, the shade that is loaded on front end is to make the cross-connecting area of its repeat exposure-making be difficult to control under focal length difference, causes finished product failure chance to heighten also uncontrollable quality, and the frame bar of its cross-connecting area is also quite obvious, is its shortcoming again.

The purpose of this utility model, provide a kind of in-mirror repeat exposure-making structure that does not have the seam lattice, it makes that the repeat exposure-making cross-connecting area dwindles when the repeat exposure-making imaging, resolution improves, and there is not the seam lattice, and can avoid commonly using and take ghost and the fuzzy case that easily produces, thereby the fault rate that repeat exposure-making is taken reduces, and improves the quality of imaging.

For achieving the above object, the utility model provides a kind of in-mirror repeat exposure-making structure that does not have the seam lattice, includes: a camera, the front fuselage of this camera is established camera lens, and tool lens in the camera lens, side joint is established film case behind the camera body, and body upper is picture window and para position plate; Its architectural feature is: between the fuselage of this camera and film case on the imaging window shade directly is set, the transparency window that these shade tool two lattice are above, and the separated place of this shade is processed into a layer gradually.

The utility model is owing to directly be located at egative film the place ahead with shade, need not via lens so can not influenced by lens, also promptly no matter camera lens how to adjust its shade to be formed at egative film repeat exposure-making cross-connecting area width then identical, again because shade is pressed close to egative film, make its handing-over zone to minimum, thereby the quality of imaging is improved.In addition, the utility model also is provided with and the corresponding para position plate of shade, and is not only very convenient when taking a picture, but and the underwriter as the integrality and the aesthetic property of scenery.

Now for making it can further understand structural design of the present utility model and technology, sincerely cooperate graphic giving again to be illustrated in the back:
