A method of driving a solid-image-pickup device is provided. The driving method includes the steps of converting light incident on a plurality of pixels arranged in matrix form into an electric signal, selecting and controlling the pixels for each of rows and/or columns, and scanning the pixels in sequence, converting at least one analog signal obtained from at least one of the selected and controlled pixels into a first digital signal, the at least one pixel corresponding to a first group of rows and/or columns, and performing first counting for data on a result of the conversion, and converting at least one analog signal obtained from at least one of the selected and controlled pixels into a second digital signal, the at least one pixel corresponding to a second group of rows and/or columns, and performing second counting for data on a result of the conversion. A period where the first counting is performed is separate from a period where the second counting is performed.
