Abstract

PURPOSE:To easily perform a blooming control and to improve a vertical transfer efficiency by a method wherein substrate voltage values in a signal integral time and a frame transfer time are changed, and a charge transfer element is driven. CONSTITUTION:A substrate voltage is, for example, set to an OV in a signal integral time and in a frame transfer time, the substrate voltage is set to a more negative value than that in the integral time, for example, a -3V. At this time, a voltage setting is changed over by means of a switch 10 connected to a substrate 8. Namely, the substrate voltage is obtained from a DC voltage V1 11 in the integral time and from a DC voltage V2 12 in the frame transfer time.
