Abstract
The utility model relates to an LCD digital photo printing machine in which a gearshift is arranged additionally to the prior conveying mechanism, rinsing machine, liens, color correction machine and display equipment of a digital photo printing machine, so as to make the skewing of the physical location of LCD pixel unit image point light project onto the photosensitive material. An LCD pixel unit is projected onto different positions of the photosensitive material and a plurality of effects of pixel is achieved, which makes the resolution of the image point achieve higher than 7,000,000 pixels. The utility model is characterized by high precision, clear image and good reduction property, ect.
Description
The utility model relates to and a kind of computer picture information is printed on digital image-forming device on the photosensitive material, i.e. digital photo printer machine.
Digital color enlargement machine generally is made up of conveying mechanism, flushing machine, camera lens, colour correction mechanism, display device.Display device shows computer picture information, by camera lens image information is projected on the photosensitive material, and photosensitive material is exposed, and the photosensitive material after will expose by conveying mechanism is through the flushing machine picture of publishing picture of processing.Existing display device is generally CRT and LCD, and is clear because of the luminous point blur margin of CRT, finally causes imaging unintelligible.Less because of the LCD pixel, cause imaging resolution not high.
The utility model aims to provide a kind of high definition LCD digital color imaging device.

Fine definition LCD digital color enlargement machine described in the utility model is by LCD screen (8), light source (10), camera lens (4), paper feed mechanism (2) form. Flushing machine (3) can be arranged. Wherein, LCD screen (8) can be that colour also can be monochromatic, and it can be with respect to photosensitive material (1) defeated Under the driving of the cooperation of mechanism of paper (2) or shift unit (5) certain displacement is arranged, make to project The physical location of LCD pixel cell (9) the imaging point light on the photosensitive material (1) is at the sensitization material Material (1) is upper to be offset. Its effect is that a LCD pixel cell (9) can project sensitization Material (1) is different physical locations upward, produce the effect of a plurality of pixel cells, improve the imaging branch Distinguish rate.
Constituting of pixel cell (9) on the LCD screen (8) to having the improvement of LCD screen now.With monochromatic LCD screen is example, and former pixel unit area is made up of inactive area (20) and effective coverage (21), and effective coverage (21) generally greater than 80%, the utility model reduces the size of pixel cell imaging point by the method that reduces effective coverage (21).The effective coverage can be kept to below 50% even littler (relevant) with the multiplying power that improves resolution.The method that realizes can be directly to print additional resistance luminescent material (16) in LCD screen manufacturing process or after making on LCD screen (8), also can hinder light in light path with the sheeting (7) of band transparent micropore (6), also can use lens light gathering.
Light source in the utility model (10) can be a cold light source, can increase ruddiness exposure assist light (11) to shorten the time shutter on the basis of cold light source, also can increase color filter (12,14,15) in light path, to improve the accuracy of color correction.Color filter (12,14,15) can be fixed on color filter fixedly on the rotating disk (13), also can be loaded in the camera lens (4), the effective aperture of color filter (12,14,15) can be not of uniform size, the luminous flux that color filter (12,14,15) sees through should be red greater than green greater than blue look, to remedy the difference of photosensitive material three primary colours film speed.
The best embodiment of high definition LCD digital color enlargement machine described in the utility model:
LCD screen (8) is made up of 1024 * 768 pixel cells (9), pixel cell (9) is colored, and size is 0.12 * 0.12, the displacement step motor drive of LCD screen (8), step pitch 0.04mm, moving direction is parallel with the direction of R (17), G (18), B (19) imaging point.Moving of its vertical direction finished by paper feed mechanism (2).Step pitch is that 0.04mm multiply by enlargement factor.The vertical direction of pixel cell (9) prints additional resistance luminescent material (16), and making the effective coverage is about 30%.Exposure process divides horizontal direction three times, vertical direction three times corresponding 1/9th of abstract image are shown on the LCD screen (8) successively, and totally 9 times, finish the printing of piece image, make final print resolution reach 3072 * 2304, i.e. 7,000,000 pixels.
Claims (8)
1. a high definition LCD digital color enlargement machine is made of LCD screen (8), light source (10), camera lens (4), paper feed mechanism (2), it is characterized in that being added with shift unit (5).
2. according to the high definition LCD digital color enlargement machine of claim 1, it is characterized in that the plain unit of LCD screen image single projects effective sensitization area on the photosensitive material roughly less than 50%.
3. according to the high definition LCD digital color enlargement machine of claim 1, it is characterized in that its light source is added with the ruddiness exposure assist light on the cold light source basis.
4. according to the high definition LCD digital color enlargement machine of claim 1, it is characterized in that having in the light path fixedly rotating disk of color filter.
5. according to the high definition LCD digital color enlargement machine of claim 4, it is characterized in that rotating disk is loaded on the nearly Jing Xinchu of camera lens.
6. according to the high definition LCD digital color enlargement machine of claim 1, it is characterized in that color filter is arranged in the light path.Color filter is red, green, blue three primary colours.
7. according to the high definition LCD digital color enlargement machine of claim 4, it is characterized in that color filter is red cut-off color filter, yellow (orange) by color filter or green band-pass filter, blue look color filter.
8. according to the high definition LCD digital color enlargement machine of claim 5, it is characterized in that fixedly three hole sizes of color filter differ.
