double sampling การใช้

The use of intrapixel charge transfer can offer lower noise by enabling the use of correlated double sampling ( CDS ).
Specific for the suppression of " offset FPN " as defined above, on-chip techniques for suppression exist, such as correlated double sampling.
Like the song, the movie is a propulsive sample, snatching from every available source and blithely exploiting what has worked before . ( The song may be the most aggressive double sample in history, plundering both Stevie Wonder's " Sir Duke " and Kool Mo Dee's " Wild, Wild West . ")
Eric Fossum, " et al . ", invented the image sensor that used intra-pixel charge transfer along with an in-pixel amplifier to achieve true correlated double sampling ( CDS ) and low temporal noise operation, and on-chip circuits for fixed-pattern noise reduction, and published the first extensive article predicting the emergence of APS imagers as the commercial successor of CCDs.
When used in imagers, correlated double sampling is a noise reduction technique in which the Reference Voltage of the pixel ( i . e ., the pixel s voltage after it is reset ) is removed from the Signal Voltage of the pixel ( i . e ., the pixel s voltage at the end of integration ) at the end of each integration period.
