ABSTRACT:
A thin film photoelectric converting device comprises a plurality of sensor blocks, each block including a thin film transistor array which is paired with a storage type image sensor array, the thin film transistor array and said image sensor array being formed on the same insulating substrate, means for simultaneously turning ON as a group the thin film transistors in each block and for sequentially driving the thin film transistors of said blocks, and reading means comprising detection means and scanning means for sequentially reading electric charge signals sensed by the storage type image sensor elements in each block.
The detection means includes a plurality of detectors of the same number as that of sensor elements in each block, said detectors simultaneously detecting electric charge signals of said image sensor elements in each block.
The scanning means scans and reads out outputs of said detectors.
