Abstract
Scanning apparatus for generating signals representing color components of successively scanned picture elements of an original colored image comprises a light source (1); means (42,45) for causing relative movement between the original image (3) and a light beam generated by the light source (1) whereby successive picture elements of the original image are scanned. Means (13) for generating a sharp light beam for each color component of each element and an unsharp light beam for at least one color component of each element are provided. Common detection means (10) receives the sharp and unsharp light beams and provides corresponding output signals. Sequencing means such as a filter wheel (13) causes the sharp and unsharp beams sequentially to impinge on the detection means (10).
