Patent ID: 7787037

Claim:
A method of driving an imaging apparatus, the imaging apparatus including a pixel unit array having a plurality of pixel units arrayed two-dimensionally, each pixel unit including a plurality of photoelectric conversion units, a charge-voltage converter common to the plurality of photoelectric conversion units, a plurality of transfer units, which transfer electric charges generated by the plurality of photoelectric conversion units to the charge-voltage converter, an output unit, which outputs a signal based on the electric charges transferred to the charge-voltage converter to a signal line, and a setting unit, line, and a setting unit which sets an electric potential of the charge-voltage converter, and each pixel unit being selected or deselected in accordance with the electric potential set in the charge-voltage converter by the setting unit, the method comprising: a first step of driving the pixel unit array so that an output unit in a selected pixel unit has continuously output, to the signal line, signals based on electric charges generated by the plurality of photoelectric conversion units in the selected pixel unit without performing an operation of deselecting the selected pixel unit; a second step of, after the first step, driving the pixel unit array so that a setting unit in a deselected pixel unit resets the plurality of photoelectric conversion units in the deselected pixel unit; and a third step of, after the second step, driving the pixel unit array so that the selected pixel unit is deselected.
