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