Abstract:
1. A solid state imaging device having: imaging devices in an array for outputting electric charge signals from said devices; means for transferring said electric charge signals read out from said image devices, said transferring means including an A/D converter, said electric charge signals including at least an empty transmission signal and an image sensing picture element signal output sequentially during along a time axis during a cycle; a clamp circuit for clamping said electric charge signals output from said imaging devices to a reference level related to a highest level in said empty transmission signal; and timing generator means for reading out said electric charge signals and generating clamp pulses for clamping a signal portion of said electric signal corresponding to at least one picture element of a picture element shading unit and for clamping a signal output by an empty transmission unit of said output signals.
