BS EN ISO 19018:2013 is an international standard that focuses on the assessment and classification of document imaging scanners. It provides guidelines and requirements for assessing the performance of such scanners, ensuring that they meet industry standards and are capable of producing high-quality digital images.
The Importance of BS EN ISO 19018:2013
BS EN ISO 19018:2013 plays a crucial role in the document imaging industry by serving as a benchmark for scanner manufacturers and users. This standard enables manufacturers to develop scanners that conform to the specified requirements, ensuring optimal image quality and reliability. Users can also benefit from BS EN ISO 19018:2013, as it helps them make informed decisions when selecting a scanner that meets their specific needs.
Assessment Criteria under BS EN ISO 19018:2013
Under BS EN ISO 19018:2013, document imaging scanners are assessed based on several criteria. These include resolution, modulation transfer function, image sampling mechanisms, uniformity, noise level, and distortion. Let's take a closer look at each criterion:
1. Resolution
Resolution refers to the ability of a scanner to capture fine details present in a document. BS EN ISO 19018:2013 specifies the minimum required resolution for different types of documents, ensuring that scanners deliver accurate and legible digital images.
2. Modulation Transfer Function
The modulation transfer function (MTF) assesses a scanner's ability to reproduce different frequencies accurately. BS EN ISO 19018:2013 sets MTF requirements for various spatial frequencies, ensuring that scanners produce high-quality images with minimal loss of detail.
3. Image Sampling Mechanisms
This criterion evaluates a scanner's sampling mechanisms, including pixel shape, sampling density, and color representation. BS EN ISO 19018:2013 ensures that scanners capture images with sufficient sampling density and accurate color representation, resulting in faithful reproduction of the original document.
4. Uniformity, Noise Level, and Distortion
Uniformity refers to the evenness of image quality across the entire scanning area. Noise level indicates the presence of unwanted artifacts or disturbances in the scanned image. Distortion assesses the accuracy of geometric reproduction. BS EN ISO 19018:2013 establishes requirements for uniformity, noise level, and distortion, ensuring that scanners produce reliable and precise digital images.
Conclusion
In conclusion, BS EN ISO 19018:2013 plays a vital role in guaranteeing the performance and quality of document imaging scanners. By adhering to this standard, manufacturers can create scanners that produce accurate, legible, and high-quality digital images. Users can rely on BS EN ISO 19018:2013 to make informed decisions when selecting a scanner that meets their specific requirements. This standard sets stringent assessment criteria, covering resolution, MTF, image sampling mechanisms, uniformity, noise level, and distortion, thus ensuring the reliability and precision of document imaging scanners.
