Description
Technical field
The utility model relates to a kind of portable digital film imaging device.
Background technology
Fast development in the audio-visual technology of digitizing, traditional film formula motion picture projection technique is replaced by digital film projection technology gradually, this is because the disposable input of cinefilm (copy) is huge, serviceable life is short, can't carry out content update, and mechanical type cinematographic equipment weight is big, the volume heaviness, need the gearing of CD-ROM drive motor and complexity etc., and that digital film projector equipment has is in light weight, volume is small and exquisite, easy to carry, need not expensive film, need not complex operations, cheap characteristics, at technical elements, digital film projector equipment is mainly based on three big technical system, i.e. DLP technology, the LCD technology, the LCOS technology.
The total system of existing no film numeral cinematographic equipment mainly is made up of the two large divisions, and first is that collection signal recording, storage, broadcast are the information management system of one, second portion be collect image reduction, audio-frequency amplification is the projection system of one.The core of information management system is hard disk management device and harddisk memory, its effect is equivalent to cinefilm, but be better than cinefilm greatly, because that it has is with low cost, volume is small and exquisite, easy to use, life-span extremely longly, harmless plays and advantage such as can arbitrarily upgrade.Owing to adopted up-to-date MP4 technology, this system can use (EVD, HDV, the contour clear signal of HiVD source) film of storing tuber of stemona high image quality such as the hard disk of 120G.This hard disk information system is update content arbitrarily, and arbitrarily increases, deletes, edits movie list and content according to the projection needs, and this is by a USB interface realization at random.And relating under the situation of copyright problem, can exchange hard disk as the exchange cinefilm and realize program updating by setting up motion picture data switching centre.Projection system is made up of light source, demonstration, imaging three parts, and wherein one chip color liquid crystal scheme can be adopted in the display part, such as Sharp's projection screen, and its transmittance height, the contrast height, well arranged, bright-colored.Light source can adopt, such as, the compound Metal halogen lamp of 250W both-end, it has brightness height, beautiful in colour, Well-recovered, cheap, the advantage that the life-span is long.Imaging moiety adopts high-quality zoom projection lens, and it can change picture size arbitrarily under the situation of projection equipment invariant position.
And by digitizing technique, the picture of projection can carry out multiple effect and switch, as wide cut, cropping, miss old times or old friends, soft, high contrast, black and white or the like.And the complete machine operation realizes Full remote controlled, and loop play, spectators' program request interaction, specific functions such as commercial breaks, Karaoke are play, preset to unattended automatically.
In the digital movies mobile playing system of State Administration of Radio Film and Television film digital program administrative center, the mode of transmission distribution via satellite and the distribution of film input disc is carried out the issuing way of digital movie, and uses the terminal projection system of Highgrade integration aspect the projection of film.
In this terminal projection system, remove outside the basic motion picture projection part, also comprise projector and multichannel audio power amplifier, this can improve the video and the audio frequency output of this system, thereby reaches the audio visual effect of movie theatre level.In a kind of exemplary digital film projector system, it is mainly by projector (being projection section), and Play Server (being the motion picture projection part) and power amplifier (being the power amplifier part) three parts are formed, and each is as a separate equipment.Wherein, the video output of Play Server is connected with the video input of projector, the multichannel audio output of Play Server is connected with audio frequency power amplifier multichannel input interface, and the stereo audio output of Play Server is connected with audio frequency power amplifier left and right acoustic channels input interface.Go out beyond the essential part of said system, this system can also comprise external equipments such as multichannel audio amplifier, rack, screen, and it forms a complete digital film projector system by connecting above-mentioned projector, Play Server and power amplifier.Here, except Play Server, projector and power amplifier also all can adopt existing device, its system constitutes simple relatively, be convenient to user's operation, and with respect to above-mentioned no film numeral cinematographic equipment, owing to adopted special projector and power amplifier, it has the requisite item of existing traditional cinema Play System, thereby in the level that can both reach existing movie theatre aspect vision and the sound effect.
But, with respect to enhancing in function aspects, the shortcoming of the above-mentioned digital film projector system that possesses projector and power amplifier is, because this system has adopted special Play Server and power amplifier, and each all exists as a separate equipment, and connect by tone frequency channel wire betwixt, make this equipment aspect volume very big and and be not suitable for carrying, and increased user's inconvenience in use.
And because above-mentioned digital film projector system is by projector, three parts of Play Server and power amplifier are formed.Should be when the user uses this projection system, projector, Play Server and power amplifier all needed preheating and initialization procedure before operate as normal, and, because projector all is connected Play Server with power amplifier, under the situation of power-on, need be according to projector, the sequence of Play Server and power amplifier is carried out the preheating and the initialization procedure of each equipment.And in the middle of prior art, this is operated by user oneself, promptly, the user need at first connect projector, and wait for that the preheating of projector and initialization procedure finish, and connecting Play Server, after finishing, the preheating of Play Server and initialization procedure connect power amplifier afterwards, the burden that this has increased the user has caused the inconvenience of using.And, owing to then need user oneself manually to control, in operating process, make a mistake unavoidably, thereby cause infringement for equipment.
Therefore, need a kind of portable digital film imaging device, it can realize the miniaturization of volume and the facilitation of operation when not reducing visual effect, so that the user carries and uses.
The utility model content
Therefore, the utility model is intended to improve the problem and the shortcoming of existing digital film projector system.
The purpose of this utility model is to provide a kind of portable digital film imaging device, and its surface-mounted integrated circuit with chip-scale is realized the video output of digital film projector equipment, thereby realizes miniaturization.
The purpose of this utility model is to provide a kind of portable digital film imaging device, and its modularization by Play Server minimizes the volume and the quality of digital movie imaging device.
According to the purpose of this utility model, a kind of portable digital film imaging device is provided, it comprises: the movie player mainboard, and it is used to read cinematic data and the cinematic data that reads is decoded, with the video and audio signal of the cinematic data of exporting this decoding; And projector, it connects the movie player module, is used for carrying out projection operation for the vision signal that receives from this movie player module.
By above-mentioned portable digital film imaging device, can when keeping visual effect, minimize the volume and the quality of digital film projector system, be convenient to user's use.And, because the integrated design of this system, reduced the complexity of raw-material use and system in the device fabrication, thereby reduced production cost.
