ABSTRACT OF THE DISCLOSURE A conventional, high resolution camera pickup tube is employed to generate the luminance signal corresponding to the greater bandwidth luminance component of a composite video signal. At least one low resolution, solid state sen- sor is combined with the tube to generate the red, green and blue color signals corresponding to the lower bandwidth red, green and blue color components of the video signal. A scan adjustment circuit precisely conforms the tube scan raster with the near-perfect geometry of the solid state sensor array. A clocking circuit synchronizes the scan rate of the sensors with that of the pickup tube. Gamma correction, matrixing and encoding are provided via video processor circuitry to generate the broadcast quality, composite video output. -1-
