Patent attributes
A driving method of a solid-state imaging apparatus includes a first driving mode wherein a start and an end of an operation of accumulating an electric charge in a pixel are set commonly to a plurality of rows of pixels, and a second driving mode wherein a start and an end of an operation of accumulating the electric charge in the pixel are set commonly to pixels in each one of the rows of the pixels. In the first driving mode, during a time period of reading out a signal from the pixels in one of the rows, a potential barrier formed in a first transferring portion is higher than a potential barrier formed in a third transferring portion for the plurality of rows of the pixels, while in the second driving mode, during a time period of reading out a signal from the pixels in one of the rows, a potential barrier formed in the first transferring portion is lower than a potential of a photoelectric converting portion, and a potential barrier formed in a second transferring portion is lower than a potential of an accumulating portion.
