two 34 comb 34 structures bd 1 and bd 2 each drain being connected at one of its ends to one of two drain buses forming the 34 backs 34 of the 34 comb 34 structures bd 1 and bd 2 which buses have respective connections for accessing from off die the accessibility of the blooming drain structures bd 1 and bd 2 for off die connection is a feature of the fig2 imager architecture dashed lines in the a 1 and a 2 registers indicate the locations of rows of charge storage stages in bands respectively associated with the red r stripe the blue b stripe the green g stripe and the near infrared nir stripe of the color stripe filter 4 of fig1 in fig2 each row indicated by dashed line is to be viewed as being associated with a respective charge transfer stage in each of the 2 10 charge transfer channels of the a 1 and a 2 registers that is each of these charge transfer channels consists of four charge transfer stages in series and during image integration times when a 1 and a 2 register clocking is halted these four charge transfer stages collect charge carriers generated respectively by photoresponse to r g b and nir components of a line image segment during each replicated line image transfer time interval interspersed among image integration intervals the clocking of the a 1 and a 2 component image registers is resumed the ones of the successive charge transfer stages in each charge transfer channel or column of a ccd register which align in the direction orthogonal to the column are considered as forming a row in that register the charge packets accumulated in the four rows of the a.
