Fig. 2 is the structural representation of this specially good effect photographic lens embodiment two.
Fig. 3 is the structural representation of this specially good effect photographic lens embodiment three.
Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
Embodiment one:
In the embodiment one shown in Fig. 1, this specially good effect photographic lens includes main frame 1；Described main frame 1 front is provided with fixed lens 2；
Described fixed lens 2 front is provided with the battery of lens being located in flexible lens barrel 3, and described battery of lens includes interior lens 31, outer lens 32,
And flexible lens barrel 3 is when stretching, make the interior lens 31 in flexible lens barrel 3, outer lens 32 spacing with flexible lens barrel 3 synchronization telescope；
Described flexible lens barrel coupling has drive mechanism, described drive mechanism to make flexible lens barrel 3 with the frequency more than 10Hz along own axes
Reciprocal telescopic.
In the present embodiment one, described flexible lens barrel 3 is made up of the sleeve of two sections of mutual sockets, the sidewall of one of them sleeve
Being shaped with helicla flute (Conventional mechanisms, not shown), it is (conventional that the sidewall of another sleeve is fixed with the axis body being constrained in described helicla flute
Structure, not shown)；Described drive mechanism is to drive the driving motor (not shown) of a described sleeve rotating, described two sections
When sleeve rotates against, described axis body carries out circumferential and axial displacement in described helicla flute simultaneously, to realize described two sections of sets
The relative telescopic of cylinder；This flexible lens barrel, drive mechanism are consistent with the dolly camera mechanism of conventional digital camera, can directly replicate or
Buying ready-made module.
Above-mentioned specially good effect photographic lens in use, forms gelatinizing effect if desired for captured image, then can make described
Drive mechanism makes flexible lens barrel 3 with the frequency more than 10Hz along own axes reciprocal telescopic, then be irradiated in flexible lens barrel 3 is saturating
The laterally consecutive vibration in light position on the interior lens 31 of mirror group, during due to frequency of vibration more than 10Hz, i.e. the vibration period
During less than 0.1s, with Ray Of Light persistence of vision be spaced in go over whole vibration area so that naked eyes feel each restraint into
Penetrate light to simultaneously appear in a width range, thus form dynamic gelatinizing effect.
In embodiment one, although described flexible lens barrel, drive mechanism can directly replicate or purchase ready-made module, but
When realizing the continuous and adjustable of flexible lens barrel 3, described driving motor needs to realize rotating with higher frequency continuously, and this makes to drive
The work load of galvanic electricity machine is heavier, is easily damaged；To this end, we are in embodiment two, this situation is improved.
Embodiment two:
In the embodiment two shown in Fig. 2, unlike embodiment one, described flexible lens barrel 3 include one section can be axially free
Flexible corrugated tube；Described battery of lens includes being located at the interior lens 31 that this corrugated tube is inner, and is located at outside this corrugated tube outer end
Lens 32；Supporting spring 4 it is provided with between described interior lens 31, outer lens 32；Described drive mechanism includes being respectively arranged on described ripple
The interior electromagnet 51 of the interior outer end of stricture of vagina pipe, external electromagnets 52, described interior electromagnet 51, external electromagnets 52 are facing each other, and mutually
Connecting periodic current module after series connection, the current cycle that described periodic current module provides is less than 0.1s.
According to embodiment two, when described interior electromagnet 51, external electromagnets 52 are passed through periodic current, interior external electromagnets
Homopolarity is relative or heteropole relative, and the interaction force between them presses current cycle change all the time, so that described corrugated tube axle
To vibration, to realize the reciprocal telescopic of described flexible lens barrel 3.Owing to embodiment two drives motor without coupling, thus be excluded that
Use and drive motor drawback, relatively drive motor, the reciprocal telescopic frequency of flexible lens barrel 3 can be greatly improved, to optimize gelatinizing effect
Really.
It addition, in described embodiment two, described interior electromagnet 51, external electromagnets 52 can also connect after being serially connected and join
There is the DC source of on and off switch；And the eigentone of described supporting spring 4 is more than 10Hz.So, when described unidirectional current
Source is after on-state is switched to off-state, and the elastic potential energy release of described supporting spring 4, so that supporting spring 4 is with it
The natural frequency vibration of self, until mechanical energy exhausts；Therefore, it can within the natural vibration time of supporting spring 4, it is thus achieved that regard
Frequently the gelatinizing effect of picture.
Embodiment three:
For the embodiment three shown in Fig. 3, unlike embodiment two, it is provided with anti-between the interior outer end of described flexible lens barrel 3
The constraint mechanism of the most flexible lens barrel transverse deformation；Described constraint mechanism includes the axial sliding sleeve 61 being fixed on flexible lens barrel 3 one end
Be fixed on the axial slide bar 62 of flexible lens barrel 3 other end, described axial slide bar 62 is inserted in axial sliding sleeve 61, makes the most sliding
Bar 62 can only move to axial with axial sliding sleeve 61.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Within principle, any amendment of being made, equivalent, should be included within the scope of the present invention.
