A high-resolution image sensor is only the start of the story. How you process its output will ultimately determine image quality. Digital imaging technology has progressed from digital still cameras into an array of por- table applications such as cellular handsets, where it serves as a differentiating feature. In applications such as automotive sensors and medical equipment, digital imaging serves as the foundation of higher-order functionality such as machine vision, instrumentation, document scanning, motion analysis and scientific high-speed image analysis. Image resolution is often seen as the most important factor determining the quality of an image. However, in all of these applications, from those that produce images for viewing or perform complex analysis of images, dynamic range plays a key role in determining how efficient and effective later imaging processing will be. Dynamic range directly affects final image quality as well as the effectiveness of any compression or analytics technologies.
