Solid-state image capturing device, method of driving solid-state image capturing device, and image capturing apparatus

摘要

A solid-state image capturing device includes: a pixel array unit including plural pixels each converting light selectively incident through a mechanical shutter into charges to be stored in a storage portion and having an overflow path through which charges exceeding a saturation charge amount are discharged; and a driving unit starting an exposure by simultaneously resetting all pixels of the pixel array unit, maintaining the overflow path in an opened state during the exposure period, and closing the overflow path during a period while signals are read from the pixels after ending the exposure by closing the mechanical shutter.

1. A solid-state image capturing device comprising:
a pixel array unit including plural pixels each converting light selectively incident through a mechanical shutter into charges to be stored in a storage portion and having an overflow path through which charges exceeding a saturation charge amount are discharged; and a driving unit starting an exposure by simultaneously resetting all pixels of the pixel array unit, maintaining the overflow path in an opened state during the exposure period, and driving the overflow path in a closing direction during a period while signals are read from the pixels after ending the exposure by closing the mechanical shutter, wherein after the mechanical shutter closes, a selection power source is set from a high level to a low level at the same time as a reset pulse is set from an inactive level to an active level, and wherein after the mechanical shutter closes and prior to the selection power source being set from the high level to the low level at the same time as the reset pulse is set from the inactive level to the active level, a transmission wiring has no change in voltage while the selection power source is set from the high level to the low level prior to the reset pulse being set from the active level to the inactive level.
