A microfilm ultra-high-definition digital image restoring device

Abstract

The invention discloses a microfilm ultra-high-definition digital image restoring device, an LED light source. An image pickup unit, wherein the image pickup end of the image pickup unit corresponds to the position of the light direct direction of the LED light source; The microfilm is arranged between the light emitting end of the LED light source and the image collecting end of the image pickupunit and perpendicular to the light direct direction of the LED light source. A computer is electrically connected with an LED light source and an image pickup unit. The device has the advantages of high degree of automation, fast speed of restoring electronic files, stable operation, simple structure of equipment and long service life, and meets the requirements of converting the information recorded on microfilm into electronic files in large quantities at low cost.

Description

technical field [0001] The invention relates to the technical field of image restoration, and more specifically relates to a device for restoring ultra-high-definition images on film to electronic files. Background technique [0002] At present, for electronic documents that need to be preserved for a long time, Article 4.5 of the national standard GB / T18894 / 2002) "Electronic Document Archiving and Management Regulations" stipulates: "An electronic document in the form of text or graphics that has permanent preservation value, if there is no paper, etc. Copies must be made into paper documents or microforms, etc. Article 21 of the "Regulations for the Implementation of the Archives Law of the People's Republic of China" stipulates: "Archives at all levels and types of archives for social use shall gradually replace the originals with microforms. ". With the development of informatization applications and the growth of a large number of electronic files, more and more electro...

Problems solved by technology

[0003] However, there is no fast and effective device for restoring microfilm ultra-high-definition images to electronic files in the existing market, and some microfilms are in urgent need of restoration operations; for example, in the archival industry, some microfilms taken by engineering drawings are stored in In the high-level urban construction archives, these films have passed for more than 30 years. With the life cycle of buildings, some buildings have reached the period of maintenance and repair. It is urgent to convert the images on the film into electronic files and output them to paper media for further processing. Construction of maintenance and repair of construction works;
