ABSTRACT OF THE DISCLOSURE Data for providing spatial and shading correction error signals during the operating mode of a television camera are taken from a two dimensional array of correction points distributed across a television image during the camera set-up mode and are stored as 8 bit words. The error correction signals extend smoothly (linearly) between the correction points. The smoothing is performed by selectively interpolating selected reference points on each video line to provide values which vary smoothly from one row of correction points to the next. A vertical interpolation circuit performs a vertical interpolation on a line-by-line basis, by adding signals produced by a multiplying D/A converter when loaded with the two values to be interpolated and weighted by factors related to the distance from each correction point. The results of the vertical interpolation circuit are fed to a horizontal interpolation circuit which ramps linearly from one reference point to the next, to provide the spatial and shading error correction output signals.
