Description
Technical field
The present invention relates to film digitization technical field, more specifically a kind of film digitization processing system.
Background technique
Traditional image file is mostly film storage, occupies storage space, and inconvenience is called.It is convenient to image in order to improve
Storage, management and the calling of archives are realized the digital management to image file, are needed film digitization.
Existing digitized processing process is: playing film using projector in projection room, then is taken the photograph by the number of profession
Shadow machine shooting, collecting launches the film image on curtain, while acquiring sound, converts number for original analog image archives
Word tone is as archives.But during transcribing herein, the film transport mechanism in projector is passed with the constant speed of 24 lattice per second
Defeated film, the duration of image file determines the transcription time, therefore transcriptional efficiency is low.
Summary of the invention
The technical problem to be solved by the present invention is to overcome above-mentioned defect existing in the prior art, a kind of energy raising is provided
The film digitization processing system of transcriptional efficiency.
To achieve the above object, the present invention is achieved by the following technical programs: a kind of film digitization processing system,
Including the projection equipment for showing film, the picture pick-up device for the curtain of imaging and for acquiring image on curtain, also wrap
It includes one and is used for while increasing the speed regulation device that projection equipment plays frame number and picture pick-up device camera shooting frame number, the projection equipment
Broadcasting frame number and the camera shooting frame number of the picture pick-up device be positively correlated；The projection equipment includes matching for reading storage image
The sound converter of the medium of sound, the sound converter, which dubs the image for being stored in medium, is converted to electric signal, described to take the photograph
As equipment receives the electric signal and is converted to digital information storage；The projection equipment at least provided with two and is projected on same
On one curtain, the polarized light piece of an image polarization for being shown and each polarized light piece are equipped in each projection equipment
Polarization direction it is different；The quantity of the picture pick-up device and the quantity of projection equipment are identical and correspond；The camera shooting
Equipment is equipped with polarized light piece and identical as the polarization direction of polarized light piece in corresponding projection equipment.
By adopting the above technical scheme, projection equipment is increased by speed regulation device and plays frame number, while increasing picture pick-up device
Frame number is imaged, that is, changes the broadcasting speed of projection equipment, play time, pole is shortened in the case where not influencing photographic effect
The big digitlization transcriptional efficiency improved using film as the image file of medium；When playing the image file after digitizing again
Slow down broadcasting speed accordingly, so that it is reduced to normal frame number, or play again by software processing, it is very convenient.With
Image digitization principle is identical, accelerates to play, acquire, and the later period restores after software processing, and efficiency is greatly improved；It is straight simultaneously
The electric signal that acquisition image is dubbed is connect, not by projection room noise image.Due to the polarization of each polarized light piece on each projection equipment
It is different to change direction, is equivalent to image coding, after being projected on same curtain, interference will not be generated, through reflecting by polarization
The identical polarized light piece decoding in direction, can be used same curtain to transcribe multiple film image archives, greatly improves transcription speed
Degree.
The further preferred scheme of the utility model are as follows: the projection equipment be equipped with it is N number of, it is N number of on N number of projection equipment (1)
The polarization angle of polarized light piece successively differs 180 °/N.
In conclusion the invention has the following advantages: increasing projection equipment by speed regulation device plays frame number, simultaneously
The camera shooting frame number for increasing picture pick-up device, that is, change the broadcasting speed of projection equipment, contract in the case where not influencing photographic effect
Short play time, greatly improves the digitlization transcriptional efficiency using film as the image file of medium；Number is played again
Slow down broadcasting speed accordingly when image file after change, so that it is reduced to normal frame number, or again by software processing
It plays, it is very convenient；Same curtain can be used to transcribe multiple film image archives, greatly improve transcription speed.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment 1.
In figure: 1, projection equipment；11, acoustic transducer；2, curtain；3, picture pick-up device；4, polarized light piece.
Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
The present embodiment is only explanation of the invention, is not limitation of the present invention, and those skilled in the art exist
It can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as in the present invention
Scope of the claims in all by the protection of Patent Law.
As shown in Figure 1, a kind of film digitization processing system is shown, including the projection equipment 1 for showing film, use
It is used in the curtain 2 of imaging and the picture pick-up device 3 for acquiring image on curtain 2 and one while increasing projection equipment 1 play
Frame number and picture pick-up device 3 image the speed regulation device of frame number, and the broadcasting frame number and the camera shooting frame number of picture pick-up device 3 of projection equipment 1 are in
It is positively correlated.
Projection equipment 1 includes the sound converter for reading the medium that storage image is dubbed, and sound converter will store
It is dubbed in the image of medium and is converted to electric signal, picture pick-up device 3 receives electric signal and is converted to digital information storage.
Projection equipment 1 is generally using parts such as projectors, including transmission, film trasport, optics, playback, body and electric appliance.Transmission
Part supplies kinetic energy by motor, passes to film trasport part through gear, sprocket wheel, toothed belt, worm and gear etc., makes film trasport part
24 lattice/second frame number is able to maintain to maintain the normal play of film.Speed regulation device is connect with motor control, is made by controlling motor
Its revolving speed increases, and then increases projection equipment 1 and play frame number；A control signal is exported simultaneously to picture pick-up device 3 and makes its camera shooting
Frame number increases.
Projection equipment 1 includes the sound converter for reading the medium that storage image is dubbed, and sound converter will store
It is dubbed in the image of medium and is converted to electric signal, picture pick-up device 3 receives the electric signal and is converted to digital information storage.
Projection equipment 1 at least provided with two and is projected on same curtain 2.A use is equipped in each projection equipment 1
In the polarized light piece 4 for the image polarization shown and the polarization direction of each polarized light piece 4 it is different；Picture pick-up device 3
Quantity is identical as the quantity of projection equipment 1 and corresponds；Picture pick-up device 3 is equipped with polarized light piece 4 and puts with corresponding
The polarization direction for reflecting the polarized light piece 4 in equipment 1 is identical.Projection equipment 1 is equipped with N number of, and N is that positive integer and N are greater than 1, preferably
Ground, N are less than or equal to 12, and the polarization angle of N number of polarized light piece on N number of projection equipment 1 successively differs 180 °/N.
In the present embodiment, using two projection equipments 1 and two picture pick-up devices 3.Two projection equipments 1 are respectively A1 and A2,
