Recent trends in the Microfiche to Digital imaging has included an additional process called OCR. This process adds significant value to a microfiche to digital conversion because of the increased functionality of the final product. OCR refers to the Optical Character Recognition and involves the process of reading information from an image after the microfiche to digital conversion has taken place. The software that is designed to perform the OCR then creates a text layer of the information it gathers from the image.
After the microfilm to digital and the OCR process has completed, you should be able to work with the file just as if the image had been created using a text editor. This means that the microfiche to digital process creates a picture of the image and the OCR creates a text version of the same image. The benefits from this conversion are immense. For example, if you where interested in finding information about a person listed in the document, you could do an automated search and a text editor would locate the name for you. This would not be possible without an efficient microfiche to digital conversion.
Consider the following, Last year, a historian approached us for a microfiche to digital conversion. He had been working with a local library gathering information from old newspaper that had been microfilmed years earlier. Without a microfilm to digital conversion, he was limited to viewing a frame at a time on a viewer and looking for information by reading off the screen. Needless to say, he was wasting lots of time. After performing a microfiche to digital and OCR process, he was able to work from his own computer and perform searches instantly.
