Abstract

PURPOSE:To improve a contrast by providing a liquid crystal panel for imprinting data and a photosensor for measuring the brightness of a data imprinted part and controlling the light quantity from a lens side. CONSTITUTION:A lamp 1 and the liquid crystal panel 2 for imprinting the data are disposed behind a film 8. The photosensor 3 for measuring the brightness of the data imprinted part performs the photometry of the incident light on the imprinted part reflected by a reflecting plate 7. A liquid crystal controller 5 controls a liquid crystal shutter 4 according to the data metered by the photosensor 3 so that the imprinted data can be imprinted with the previously set contrast. Namely, the liquid crystal shutter 4 adjusts the transmitted quantity of light in front of the film. Thus, the data which is easy to be viewed can be imprinted with the set contract regardless of the brightness of an object photographed by a lens 6.

れるように制御する。The data imprinting device of the present invention includes a lamp placed on the back of the film, a liquid crystal panel for data imprinting, a photo sensor for measuring the brightness of the data imprinting area, and a device that controls the amount of light from the lens side. [Embodiment] FIG. 1 is a block diagram of a data imprinting device according to an embodiment of the present invention. In the figure, 1 is a lamp, and 2 is a liquid crystal panel for data imprinting, which is placed behind the film 8. 3 is a photo sensor for measuring the brightness of the data imprinted area, and measures the incident light of the imprinted area reflected by the reflector 7. The liquid crystal control device 5 controls the liquid crystal shutter 4 based on the data released by the photo sensor so that the imprint data is imprinted with a preset contrast.

る。That is, the liquid crystal shutter 4 is located in front of the film and adjusts the amount of light transmitted. For example, by utilizing the fact that the amount of light transmitted by a nematic liquid crystal changes depending on the voltage, this photoelectric adjustment can be easily performed. Therefore, if the data imprinted area on the film is bright, by reducing the amount of transmission of the liquid crystal 4, the area around the data written by the liquid crystal shutter 2 will be darkened, and a recognizable contrast will be obtained.
