The solid-state image pickup device of the invention includes: a plurality of optoelectronic transducers arranged in an array; a plurality of vertical transfer sections each for reading charges from optoelectronic transducers and vertically transferring the read charges; a horizontal transfer section; a charge detection section for converting the horizontally transferred charges to signal voltages and the like; and a control section. The control section outputs signals so as to obtain either a signal corresponding to the sum of charges from an optoelectronic transducer belonging to one column and belonging to one of alternately selected rows and an optoelectronic transducer belonging to a column adjacent to the one column and belonging to a row other than the alternately selected rows, or a signal corresponding to the sum of charges from optoelectronic transducers belonging to a same column, every predetermined even number of continuous rows of optoelectronic transducers.
