Abstract
A digital image microfilm camera is a device which shoots a digital image to a film quickly, and is formed by a display unit, a lens, a liquid crystal display (LCD) drive panel, a system control panel, a system power panel, a film feed mechanism, a radiator fan, a system chassis and a system software, wherein the display unit is formed by three liquid crystal panels, the system software is arranged on a computer, the computer carries out the photographing operation through the control of a serial port, the digital image which needs to be recorded onto the film is sent to the digital image microfilm camera through a display signal cable and is imaged on the liquid crystal panels of the liquid crystal display unit of the digital image microfilm camera, LED light sources which radiate the liquid crystal panels are accurately controlled in the system, an image is exposed and imaged on the film photosensitive surface of the film feed mechanism through the lens, then the whole shooting-to-film process of a digital coloured image is finished, and finally, a photographing film of the digital coloured image can be obtained by developing and printing the exposed film through a film developing and printing device.
Description
Affiliated technical field
The digital microfilm recorder of liquid crystal imaging is a kind of with directly expose photographic equipment to film of digital image.Digital image is sent into digital microfilm recorder after the special software on the machine is handled as calculated, imaging on its display unit, by led light source irradiation, through camera lens as required ratio on film, expose, develop and print equipment by film and develop and print, obtain the film of digital image.Be applicable to the long preservation of electronic record, digital picture and professional digital photographic image, can be widely used in library, archives industry and individual's e-file long preservation, and provide a kind of new pattern for the e-file exchange.
Background technology
Along with the continuous development of computer information technology, digital image is widely used in the every field.The popularization and application of digital photographing and scanner has realized not using film directly digital picture to be present in the digitizing storer, and the repeated use of digitizing storer and the earth have reduced the photograph cost, use more aspect.On the other hand, the data preservation that produces a large amount of digital image information is mainly undertaken by media such as tape, CD, disk cartridges.
The digital format media holding time of prior art storage at present is shorter relatively, and is subject to the application system environmental restraint, and is not directly perceived.For having the digital image information that long preservation is worth, need regularly media to be checked, regularly duplicate again, bring inconvenience to long preservation.Convert digital image to analog form and be recorded in a kind of effective means that can be used as the long preservation digital image on the film, it is long that film is preserved the life-span, generally all more than 100 years, can satisfy the demand of digital image long preservation.The film epigraph is not limited by the application-specific system environments, and image is directly perceived, can directly check image result on the film with simple tool, and microfilm can reduce digital image by scanner.Therefore use the Film Recording digital image, a kind of form as long preservation has very outstanding advantage.
Summary of the invention
The application demand of, gray scale digital image recording colored long preservation to the film in order to satisfy, the utility model adopts three liquid crystal imaging technical approach, it is miniature to film that colour, gray scale digital image are photographed fast, is a kind of digital image microfilm recorder of low-cost digital signal revolving die analog signal.
The technical scheme that its technical matters that solves the utility model adopts is: the digital image microfilm recorder adopts the serial port cable, shows that cable is connected with computing machine that computing machine is installed two output driving circuits that show.The liquid crystal display of digital image microfilm recorder is as a slave display of computing machine, digital image microfilm recorder system software is installed on computers, the digital image that need photograph on the film can use CD, USB flash disk, medium such as disk cartridge enter data in the computing machine, start the digital image microfilm recorder system software on the computing machine, carry out shooting operation, under system software controls, the digital image that need record film is delivered to imaging on the liquid crystal board of liquid crystal display of digital image microfilm recorder, led light source irradiating liquid crystal plate in the simultaneity factor control image-display units, image is being walked exposure image on the light reaching the film face of film mechanism through camera lens, finish a digital image photography to the film overall process.Film mechanism is walked in the system software controls of digital image microfilm recorder, and the new film of advancing is to exposure position, for next photography is got ready.Digital image microfilm recorder system software can be set and carry out automatically photography fast continuously, also can individual photography of manually-operated.Finish the film of exposure and send in the magazine that takes up, from the digital image microfilm recorder, take out, develop and print equipment through film and develop and print the photographic film that obtains digital image.
The system chassis of digital image microfilm recorder is the lucifuge camera bellows, in the cabinet by liquid crystal display, camera lens, liquid crystal display drive plate, system control panel, system power supply plate, walk film mechanism, radiator fan is formed.
In system chassis, walk film mechanism, camera lens, liquid crystal display fixed order on the system chassis base, it is characterized in that: camera lens is at the image of liquid crystal display output minute surface and walk between the light reaching the film face of film mechanism, three plane parallel, and three planar central are positioned on the same axle center.
The mode of operation of walking film mechanism and the film of the ordinary camera mode of advancing is identical, and film is contained in the special adhesive magazine, and film size is two kinds of 35mm or 16mm.Film after the exposure is collected away in the in-house receipts film cassette of the same type of film, and bright room environmental takes out behind the film loader to develop and print on the equipment to film and washes.
In order to satisfy the different application demand, the present utility model the image-display units parts of two kinds of structures.3 reflection liquid crystal Lcos and 3 transmission-type liquid crystal board LCD.Lcos has the optical efficiency height, the advantage that resolution is high, but light channel structure relative complex.The LCD light channel structure is simple, and the display unit volume is little, can select to be applied on the different demands according to advantage separately.
