Disclosed herein is a photographing device that includes a number of light-receiving elements, a number of vertical transfer registers, a first drive-voltage applying electrode, and a second drive-voltage applying electrode. The light-receiving elements are arranged in a horizontal direction and a vertical direction. The vertical transfer registers transfers the electric charges accumulated in the light-receiving elements in the vertical direction. The first drive-voltage applying electrode is arranged parallel to the vertical transfer registers, for applying a drive voltage to a specific one of the vertical transfer registers. The second drive-voltage applying electrode is arranged perpendicular to the vertical transfer registers, for applying a second drive voltage to the vertical transfer registers at the same time. The electric charges accumulated in the light-receiving elements are transferred to the vertical transfer registers, due to the voltage output from the first drive-voltage applying electrode or the second drive-voltage applying electrode, or the voltages output from both electrodes. Therefore, the light-receiving elements can have different sensitivities, and the photographing device can photograph dynamic scenes in a broad dynamic range.
