ABSTRACT:
A solid-state photoelectric transducer comprises a plurality of output units for photoelectrically converted signals which units are constructed of: a plurality of photoelectric converter elements, a plurality of signal accumulators for accumulating signals output from said photoelectric converter elements corresponding to an amount of light incident on said photoelectric converter elements, each of said signal accumulators being connected with an associated one of said photoelectric converter elements; a plurality of devices for returning the signal accumulators from a signal accumulating state to an initial state, each of said devices being connected with an associated one of the signal accumulators; a plurality of signal amplifiers for outputting amplified signals corresponding to the signals accumulated in the signal accumulators, each signal amplifier being connected with an associated signal accumulator; and a plurality of cross-talk preventors for preventing cross-talk of the signal output from each signal amplifier, each signal amplifier being provided with one of the cross-talk preventors; a plurality of said signal amplifiers being exclusively selected by a unit selecting signal in each of said output units, said output units having a controlling line which transmits a controlling signal for controlling each of the return devices to the initial state in common, and the signal amplifiers of the same level in each output unit having a signal output line in common.
