Abstract
A video projection type of digitalized enlarger for colour photo is composed of computer, peripherals, display, keyboard, projector and colour enlarger. The digital signals recorded on media such as digital storage, disk and magnetic tape are converted into video image signals by computer. Said video image signals are projected on printing paper in colour enlarger. After developing, high-resolution and high-fidelity colour photo is obtained. It can also be used to copy photosensitive film.
Description
The present invention relates to a kind of video projection digit color enlarger.
Known colour enlarger, it can be with the color film projection on printing paper, output photochrome after washing.But this machine can not be handled the digital memory of no film or number (word) signal of storage carrier recordings such as disk, tape.Though digital (word) conversion of signals can be become vision signal by computing machine, only can be by computer peripheral printing of inkjet printer output colour picture, its weak point is that sharpness is relatively poor, cost is also higher.
Task of the present invention provides a kind of video projection digit color enlarger, and it can convert the digital signal of storage carrier recording to photochrome, can promote clearness and reduce cost again.
Task of the present invention is finished like this: the digital signal that will store carrier is imported Computer Processing from interface circuit, through operation keyboard and revise and be reversed to negative-appearing image after display video signal displayed image meets the requirements and transfer to the projector of setting up from the computing machine delivery outlet, projector is projected to sensitization on the enlargement of color photos machine printing paper with image beam, and then washes, exports photochrome.
Because the present invention makes up computing machine and external unit color monitor thereof and keyboard and projector, enlargement of color photos machine in an orderly manner, made full use of advantage separately, thereby realized the digital signal of storage carrier recording is converted to video signal, through revising projection, sensitization, flush out the photochrome of high definition, high-fidelity, also reduced cost simultaneously significantly.
The concrete structure and the using method of invention are provided by following embodiment and accompanying drawing thereof:
Fig. 1 is the outfit and the workflow diagram of the video projection digit color enlarger of proposition according to the present invention.
Describe the details and the working condition of the video projection digit color enlarger that proposes according to the present invention in detail below in conjunction with Fig. 1:
The storage carrier (1) of digital memory or disk, tape etc. is imported computing machine (2) with the digital signal that is write down from interface circuit, handling keyboard (6) makes computing machine (2) convert digital signal to vision signal, and correction is reversed to negative-appearing image behind the erect image that display screen (7) upward shows, give projector (3) from computing machine (2) delivery outlet with video signal transmission, by projector (3) image beam is projected to again and inserts sensitization on colour enlarger (4) printing paper, wash, export photochrome (5) then.
Projector (3) selects for use the digital micro-mirror projector comparatively advanced, also can select in LCD projector, liquid crystal light valve projector and the oil film light modulator projection device any for use, wherein selects for use the projector with data/graphing capability for best.
This field of concrete operation method personnel of computing machine (2), projector (3) and colour enlarger (5) all can grasp, and no longer carefully state.It is also in full force and effect that device of the present invention is used to copy sensitive film.
Claims (3)
1, video projection digit color enlarger, it comprises computing machine and color monitor and keyboard, projector and enlargement of color photos machine, it is characterized in that the digital signal of storage carrier (1) is imported computing machine (2) from interface circuit to be handled, after keyboard (6) is revised display (7) video signal displayed image, be reversed to negative-appearing image and transfer to projector (3) from computing machine (2) delivery outlet, projector (3) is projected to sensitization on colour enlarger (4) printing paper with image beam, washes, exports photochrome (5) then.
2, video projection digit color enlarger according to claim 1 is characterized in that projector (3) is the digital micro-mirror projector, also can be LCD projector or liquid crystal light valve projector or oil film light modulator projection device.
3, video projection digit color enlarger according to claim 1 and 2 is characterized in that projector (3) is the best with data/pattern projector.
