Abstract
Description
【発明の詳細な説明】 本発明はカラーネガ画像反転装置に関するものである。[Detailed description of the invention] The present invention relates to a color negative image reversal device.
カラーネガフィルムは補色に近い色で、明暗が反対に仕

のフィルムを印画紙あるいはカラーポジフィルムに全部
焼付でみる必要があった。Color negative film has colors that are close to complementary colors, and is finished with opposite brightness and darkness, and is also colored with a colored coupler, so it is not as obvious at first glance as if you were looking at a positive (reversal film) photograph, even if it is overexposed or underexposed. Even if there was a color negative film that seemed to have failed due to camera shake, it was necessary to print the entire film onto photographic paper or color positive film.

、すこぶる便利である。For this reason, if a store that prints black negative film has a device that can immediately observe the color negative film in an inverted state, the photographed negative color film will be seen in the same state as the one in which it was printed, and it may fail. It's extremely convenient because you can avoid things and print only what you like.

のである。In view of the above-mentioned points, the present invention has devised a color negative image reversal device that allows a reversed image to be observed immediately when a color negative is inserted. It consists of an image pickup tube, an amplifier circuit, an inversion correction circuit, and a color monitor display device. In other words, light obtained from a light source through a color negative film is converted into an electrical signal by an image pickup tube to extract a color signal, and after this color signal is electrically inverted, it is converted to light on a color monitor display device and the inverted image is observed. The idea is to do so.

プラーの色も補正されて、ポジの状態で映し出される。The light emitted from the light source (13) is equalized in light intensity distribution by the diffuser plate (2) and then enters the color negative film inserted into the film insertion section (3). Colored couplers are used in the printing process, but in the present invention it is necessary to correct the color when monitoring the color, and when the color temperature of the light source and camera system are different, the color temperature changes Therefore, a color correction filter (4) that combines these OII functions is installed in front of the camera lens (5).The light that has passed through the camera lens (5) is placed in front of the image pickup tube. The striped filter color is red, the edges are
The optical signals are separated into three colors of blue, each converted into an electrical signal by an image pickup tube (6), amplified by an amplifier circuit (7), and then inverted by an inversion correction circuit (8) to be displayed on a color monitor display device. (9), the color of the colored coupler is also corrected, and the image is projected in a positive state.

できる。As mentioned above, in the apparatus according to the present invention, just by inserting the entire color negative film, the colors are immediately reversed, and the color of the colored coupler is also corrected and an image is projected.
It becomes possible to easily evaluate all photographic conditions such as color tone and focus. Therefore, if this device is installed at a store that sells color negative film printing, it will be possible to immediately show customers whether the negative film is good or not, and prevent them from having to burn the entire film if the film fails, forcing them to waste money. Trouble can be avoided.
