Abstract
The utility model discloses a film television converter, being the equipment which can make the film copy content converted into the telefilm and being widely applied to the television station and each electronic teaching unit. The film television converter comprises an optical system and an audio system, the optical system comprises a small ground glass screen, a perfect reflection flat mirror and a half-reflection and half-transmission flat mirror, and the audio system is an II type attenuator with adjustable attenuation multiples. Compared with the product of the Japan SONY, the film television converter simplifies the design of the optical system and increases the audio system. The film television converter is appropriate for being matched with the projectors and the cameras with any model number.
Description
Film TV transducer is a kind of equipment that can convert the film copy content to telefilm.
This transducer is made up of optical system and audio system two parts.With the Sony corporation of Japan product relatively, transcribe under the prerequisite of quality not influencing image, simplified Design for optical system, and increased the audio frequency functional transcription.It is applicable to the supporting use of projector gamma camera with various models.The pictures and sounds conversion effect is enough to satisfy the needs of TV station and each electronic teaching unit.Because cost is lower, is suitable for penetration and promotion.
Optical system is made up of ground glass the small screen, fully-reflected plane mirror, half reflection and half transmission level crossing.Audio system is the adjustable ∏ type attenuator of an attenuation multiple, and circuit is seen accompanying drawing 1.
The transducer external form is a cuboid metal shell, sees accompanying drawing 2.Locate to place the ground glass the small screen at plane ABB ' A '; In the lower right corner of plane C ' D ' DC, be the audio system terminal block; Open a slot respectively at plane B ' C ' CB and A ' D ' DA place, mirror in the transducer for two projector light.
Level crossing 2-2 ' that two block lengths are square and 3-3 ' all are fixed on the ABCD of casing baseplane, and the plane of two level crossings is all vertical in baseplane ABCD.Its vertical view is seen accompanying drawing 3.
In accompanying drawing 3,1-1 ' expression ground glass the small screen; 2-2 ' expression half reflection and half transmission level crossing; 3-3 ' expression fully-reflected plane mirror.Eyeglass 2-2 ' and 3-3 ' are orthogonal, and the extended line of straight line 2-2 ' and 3-3 ' is all in straight line AD angle at 45.
Finish transcribing of image by optical system in transducer, its process is (referring to an accompanying drawing 4): the light that the projector first penetrates, and after the reflection through half reflection and half transmission mirror 2-2 ' in the transducer, imaging is on the small screen 1-1 '; The light that projector second penetrates, after the reflection through transducer inner total reflection mirror 3-3 ', again by half reflection and half transmission mirror 2-2 ', imaging is on the small screen 1-1 ', and gamma camera is aimed at the small screen 1-1 ' production.First, second projector is projection in turn, can guarantee that visual transcription is uninterrupted all the time.
Transcribing of sound then relies on audio system to finish.
This transducer is easy and simple to handle, and concrete steps are:
1, transducer, projector first and second and gamma camera have been put by the position shown in the accompanying drawing 4.
2, in the position of level and vertical direction adjustment projector, make the light of projector drop on transducer the small screen center.When projector was not put film, this step was whole easier.
3, use projector normally to show, allowing clearly, picture appears on the transducer the small screen.
4, gamma camera is focused to the quasi converter the small screen, observe monitor, draw appropriate screen.Should use the auto iris shelves during operation.
5, above process can be carried out repeatedly, until till obtaining conforming with the image that duplicates requirement on the monitor.
6, the audio input jack (IN) that connects projector loudspeaker audio output jack and transducer with voice-frequency cable.
7, the external microphone jack that connects transducer audio output jack (OUT) and gamma camera again by voice-frequency cable.
8, connect monitor speaker at the SP place, the monitoring selector switch on the transducer is pulled to the ON position, the monitoring of can recording.
The 6-8 step can be referring to accompanying drawing 1.
After finishing above-mentioned steps, the sound and the image that can begin between film and the TV are transcribed.
Claims (3)
