Abstract

A charge injection device sensing an optical radiation pattern is driven at an operation sequence where the charge holding mode is inserted between the charge storing/readout mode and the charge injection mode. The charge holding period is effective for picture elements influenced by charges injected into the substrate after the readout operation placed spacially far and timed. The problem of cross-talk at high speed operation is resolved.
