Abstract:
1. A method of operating an imaging pixel array having pixels arranged in rows and columns, said method comprising: resetting a photosensor and a charge storage region of a first pixel in a first row of said array to a first bias state using a first higher voltage supplied from a first row select line; after said resetting, initiating charge integration by said photosensor of said first pixel; during said charge integration, setting said charge storage region to a second bias state using a second lower voltage supplied by said first row select line; and resetting a photosensor and a storage region of a second pixel in a second row of said array to said first bias state using said first higher voltage supplied from a second row select line, said resetting of said photosensor and storage region of said second pixel occurring during charge integration by said photosensor of said first pixel.
