<P>PROBLEM TO BE SOLVED: To reduce time for reading charge packets from a CCD. <P>SOLUTION: A method for reading a column of charge packets representing two colors to first and second horizontal shift registers connected in parallel, the method includes the steps of: (a) transferring all charge packets of a column of charge packets from a plurality of vertical CCDs to the first horizontal shift register; (b) transferring a charge packet of a single color from the first register to the second shift register to reduce the number of charge packets in the first register; and (c) shifting charge packets within both the first and second horizontal shift registers so that adjacent charge packets of the same color in the column of charge packets are respectively and simultaneously summed in the first and second horizontal shift registers, for reducing the time for reading, thereby further decreasing the number of charge packets in the first and second shift registers to 1/2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
