ABSTRACT:
A linear sensor for sampling vertically opposed pixels of a plurality of vertically arranged sensor rows substantially at a time. A plurality of horizontal transfer registers and a plurality of shift gates are provided to oppose the plurality of sensor rows. A vertical transfer register is provided at one end of the plurality of horizontal transfer registers. In the vertical transfer register, the signal charges which have been transferred by the plurality of horizontal transfer registers are transferred sequentially in vertical direction. A charge/voltage converter unit is provided at the output of the vertical transfer register. The signal charges accumulated in the vertically opposed pixels are sequentially transferred to the charge/voltage converter unit in a repetitive manner.
