Microfilm photographing method, electronic device, system and storage medium

Abstract

The present application relates to a microfilm photographing method, electronic equipment, system and storage medium, wherein the method includes: obtaining the light transmission amount of the microfilm and the moving distance based on the previous stop position; based on the light transmission amount and / or the moving distance, controlling The microfilm driving mechanism stops; after the microfilm driving mechanism stops, the digital camera is controlled to take pictures. The present application can determine whether the front boundary or the rear boundary of the microfilm image has reached the detection position by obtaining the light transmission amount of the microfilm; by obtaining the number of turns of the meter wheel, the distance that the microfilm moves relative to the previous stop position can be determined; For relatively long microfilm images, it is impossible to take photos at one time. The next photo position can be determined by the number of turns of the meter wheel, so as to realize continuous and automatic photo taking of the whole roll of microfilm, effectively reducing the labor load and improving the photo taking efficiency. , to meet the needs of large batches of microfilm photography.

Description

technical field [0001] The present application relates to the technical field of microfilm photographing, and in particular to a microfilm photographing method, electronic equipment, a system and a storage medium. Background technique [0002] Digital microfilm technology is to record electronic information on microfilm in the form of images. It is a carrier that uses the chemical properties of film to record electronic information. It can record a large amount of electronic data information and is suitable for permanent preservation. The microfilm recorded by digital microfilm technology has a high shrinkage rate and a large amount of information. With a traditional film reader, it is impossible to directly view the detailed content. Microfilm scanning technology or ultra-high-resolution digital camera shooting technology is required to scan the microfilm. The film image is captured as an electronic image, which can be checked in real time on the monitor after the image is ...

AI Technical Summary

Problems solved by technology

Microfilm readers and scanners widely used at present are still unable to automatically scan microfilms in batches, especially in the case of different image sizes on the same film, and can only rely on users to manually control the microfilms to rotate clockwise or counterclockwise

Usually, a reel of 16mm microfilm has about 1200-2500 frames, and a reel of 35mm microfilm has about 600 frames. Due to the large number of frames, it is very difficult to manually shake the handle of the microfilm roll. Laborious, unable to meet the needs of large-volume, automatic and continuous scanning of microfilm
