摘要

A method for reading out charge from an interlined CCD having a plurality of photo-sensing regions and a plurality of vertical shift registers, and each photosensitive region is mated respectively to a CCD of a vertical shift register and a color filter having a repeating pattern of two rows in which each row includes at least two colors that forms a plurality of 3 line sub-arrays sequentially numbered in the space domain; and the color filter spanning the photo-sensing regions, the method includes reading out lines (1 and 3) into the vertical shift register that keeps the colors separated; summing the charge in lines (1 and 3); transferring one row of the summed charge into a first horizontal charge-coupled device; transferring alternate charges in the first horizontal charge-coupled device into a second horizontal charge-coupled device; summing sets of two charges in the first horizontal charge-coupled device; summing sets of two charges in the second horizontal charge-coupled device; and reading out the charge in both the first and second horizontal shift register with a half-resolution clocking sequence.
