Device for electrical variable magnification of document image

摘要: A system for altering the size of an image by a desired magnification after optical scanning thereof provides plurality output scan values differing in number from sampled signals produced during scanning. The are representative density at pixel locations spaced rows and columns across image, with spacing being dependent upon selected value. includes means providing series sequences signals, converter converting to corresponding digital values. control circuit is responsive value interpolation synchronism successive indicate spatial relationship respect pairs An interpolates between provide
