Digital Enlarger {Digital Enlarger}

The present invention relates to a digital enlarger for exposing and expanding various digital images on photo paper by photoexposure as well as a film, and more particularly, to a digital image by using an analog enlarger that can only expose and enlarge a film. And it relates to a digital enlarger that makes it possible to print a variety of images, such as film on photo paper.

A typical magnifier is a machine used to print large photographs, which determines the desired print size, then manually adjusts the overall height of the exposure machine to fit the size to be enlarged, and then adjusts the height of the fixed lens so that the focus is on the photo paper. Match the image. The white light emitted from the light source is added to the light emitted through the film with a C, M, Y filter to lighten the negative of the film to cause photo paper to be sensitized to cause latent image on the paper.

Such a conventional enlarger has an analog method in which an image source is limited to a film, so that the quality of a photograph and the degree of expression of a photographed subject are all determined at the time of photographing, and thus, it is impossible to correct them once photographed. In other words, if the image source is analog, in order to express the image according to the intention of the photographer, it is inevitable to acquire high-tech skills considering the characteristics of the lens, the shooting technique, and the surrounding environment, and even if the technique is acquired, There is a limit in nature. In addition, the basic color settings, that is, the C, M, Y filter settings, each color adjustment for each picture and the problem that you need to remember and reset the filter value adjusted for various environments. As mentioned above, the color, saturation, and brightness are different depending on the method of taking the image, and the hue adjustment is inevitable due to the complementary color relationship. Therefore, the C, M, and Y filters must be adjusted accordingly, and the light exposure time must be changed. .

Therefore, in the case of ordinary people who have not acquired the above-mentioned high-tech skills, in order to express the image as intended, they have to pay a high price to a professional photographer who has the high-tech skills and shoot at a specially set place. There was discomfort and discomfort. In addition, in case of analog system, if the film is damaged, it cannot be recovered, and even if it is taken again, it is not possible to obtain the exact same picture as before.
