What is a Scanner?
The scanner is a data capture device which is designed to capture repetitive data and to perform formatting functions on the data steam continuously as it is being input. The data output from the scanner to the computer is very accurate and does not need any editing later. The prerequisites for successful scanning process are proper media, data integrity, accurate data recognition and quality output.
Why Do You Use OCR Scanning?
Optical character recognition abbreviated as OCR is software tool employed in most of the optical scanners. OCR converts printed characters into digital text which is editable such as Word or Text. OCR scanning is preferred over other methods of data entry to reduce manual data entry errors, handle peak loads, perform scan corrections, and output readable high quality digital document. OCR scanning performs faster and accurate text recognition thereby saves cost, effort, and time. The OCR scan takes very less time to process after uploading the image thereby user saves a lot of time. The OCR scan software supports many (PDF, JPG, GIF, TIFF or BMP) file formats. Multi lingual documents can also be scanned.
How Does the Scanner OCR Work?
The scanner OCR works in three stages. The input document is read in the first stage to understand the document type, structure, formatting, non-textual contents, and language, etc before the scanning begins. For this, the scanner executes translation of images of typed text into machine editable text. Then, a detailed scanning is done by the application of an internal OCR Processing Rule Set. Next, a specific batch of documents is read and the output text is verified. Thereafter, OCR levels 1, 2, and 3 levels are applied based on the user requirements. Level 1 is applied to convert plain text documents to be scanned. OCR level 2 is applied to documents with complex layouts including flowcharts or graphics. OCR level 3 corrects the data entry and the scanned portions.
