A 5k-pixel CCD linear image sensor with adjacent RGB photodiode rows

A 5000-element CCD linear image sensor with adjacent RGB photodiode rows has read-out signal charge of the middle row by charge transfer through a vacant neighboring photodiode row. Conventional color sensors have an interval from 6 to 8 lines between neighboring photodiode rows, and have several disadvantages, such as large memory required to compensate positional differences in red, green, and blue arrays, weakness against fluctuation of scan speed and so on. The device reported in this paper eliminates the above problems.
