A still image pickup camera has a solid state image pickup device comprising an image pickup area, a temporary storage area, and a horizontal shift register. The signal charges in the image pickup area are transferred to the temporary storage area by the transfer pulses which are given for a vertical blanking period. Clear pulses which are equivalent to the transfer pulses are given at a desired timing in the interval between the vertical sync signals so as to enable the photo sensing interval (storage interval) in the image pickup area to be reduced and varied, thereby transferring the signal charges in the image pickup area to the temporary storage area and clearing the image pickup area.

A still image pickup camera comprising: a solid state image pickup device having an image pickup area, a temporary storage area, and a horizontal shift register; clock generating means for outputting within a vertical blanking period a group of first high-speed transfer pulses to transfer storage signal charges of one field in said image pickup area to said temporary storage area, for outputting within one field interval a group of second transfer pulses to transfer the storage signal charged of one field in the temporary storage area by an amount of every horizontal line synchronously with a horizontal sync signal to said horizontal shift register, and for outputting every horizontal scan period a group of third high-speed transfer pulses to transfer the image data of one horizontal line, by an amount of every pixel, which has been transferred to the horizontal shift register; clear pulse generating means for generating one or more times a group of high-speed clear pulses at a desired timing in an interval between adjacent vertical sync signals; and means for feeding said group of high-speed clear pulses to both said image pickup area and temporary storage area to clear both these areas.
