ABSTRACT:
An optical scanner with variable line resolution, said scanner collecting information from an original along lines with a predetermined mutual spacing. A calculating unit calculates the location of lines with desired resolution with respect to the scanned lines in response to a desired resolution. A line detector registers optical information along lines on the original and supplies a signal representing the registered, optical information. The information signal is branched along two branches in a branch means. A delay is coupled in one of said branches and is adapted to delay the information signal passing in the branch for a period of time corresponding to a line length in said information signal. An interpolation means receives the information signals from said branches and forms as a desired line an interpolation signal between information signals in response to the location of the desired line with respect to the location of the scanned lines.
