A linear array is a type of CCD (charge-coupled device) used in flatbed scanners and high-end cameras, consisting of several thousand RGB-filtered elements arranged in a single narrow row. The array spans the full width of the image and scans it line by line as the sensor moves along the length of the subject.
Understanding linear arrays is important for photographers, scanners, and imaging professionals who require high-resolution, precise digital capture. This technology ensures accurate colour reproduction, fine detail, and consistent scanning performance, making it essential for professional photography, large-format scanning, and archival imaging applications.
