摘要：
A method for controlling a linear sensor comprises: transferring an electric charge converted in a photoelectric conversion unit to a charge storage unit; transferring the electric charge stored in the charge storage unit to a transfer register; driving the transfer register; removing an electric charge stored in the charge storage unit; and controlling to successively execute the first transferring, the second transferring, the driving and the removing in synchronization with a trigger signal generated on a predetermined cycle.
