Solid-state imaging device having an amplifying means in the matrix arrangement of picture elements

A solid-state imaging device comprising:

• a plurality of photoelectric conversion elements, arranged in the form of a matrix array having a plurality of rows and columns, for accumulating charges corresponding to light information;
• a plurality of amplifying means for converting the charges accumulated in each of said photoelectric conversion elements into currents or voltages and for amplifying the same, each of said amplifying means having an input and an output;
• a plurality of selectively actuated switching means coupling said plurality of photoelectric conversion elements to respective inputs of said plurality of amplifying means, said switching means selecting a prescribed one of said plurality of photoelectric conversion elements so as to supply accumulated charges thereat to an input of said amplifying means;
• a plurality of resetting means for resetting the charges at the inputs of said amplifying means;
• signal lines for transferring to outside said matrix array the currents or voltages outputted by said amplifying means located within said matrix array;
• and
• detecting means, coupled to said signal lines, for detecting with respect to each one of said photoelectric conversion elements the difference between signals outputted by said amplifying means corresponding to reset charge levels at the inputs of said amplifying means and those signals corresponding to when charges, indicative of light information, are present at the inputs thereof.
