• H04N 25/61 the noise originating only from the lens unit, e.g. flare, shading, vignetting or "cos4"
• H04N 25/616 involving a correlated sampling function, e.g. correlated double sampling [CDS] or triple sampling
• H04N 25/617 for reducing electromagnetic interference, e.g. clocking noise
• H04N 25/618 for random or high-frequency noise
• H04N 25/62 Detection or reduction of noise due to excess charges produced by the exposure, e.g. smear, blooming, ghost image, crosstalk or leakage between pixels
• H04N 25/63 applied to dark current
• H04N 25/65 applied to reset noise, e.g. KTC noise related to CMOS structures by techniques other than CDS
• H04N 25/67 applied to fixed-pattern noise, e.g. non-uniformity of response
• H04N 25/68 applied to defects
