Abstract:
1. A solid-state image pickup device comprising: a pixel portion in which unit pixels are arranged in a matrix form; horizontal signal lines of plural rows which are wired to said pixel portion on a row basis; plural vertical signal lines which are wired commonly to said horizontal signal lines of plural rows; vertical driving means of plural systems which select the respective pixels of said pixel portion every row over plural different rows, making the accumulation time of signal charges of each pixel of the plural selected rows different among the plural rows, and successively outputting to said plural vertical signal lines the signals which are output from the respective pixels to said horizontal signal lines of plural rows; and horizontal driving means for successively selecting the pixels of plural rows which are selected by said plural systems of vertical driving means; wherein each of said unit pixels comprises a photoelectric converter, a read-out transistor for reading out a signal charge, accumulated by said photoelectric converter, into a storage unit, a read-out selection transistor for selecting the reading out of the signal charge by said read-out transistor, an amplifying transistor for converting the signal charge stored in said storage unit into an electrical signal and for outputting the electrical signal as a pixel signal, a reset transistor for resetting the storage unit, and an output selection transistor for selecting the output of the pixel signal provided by said amplifying transistor a read out transistor and an output selection transistor; and said horizontal driving means feeds a horizontal selection pulse to said read out selection transistor and said output selection transistor.
