fpn fixed pattern noise 中文意思是什麼
fpn fixed pattern noise
解釋
固定樣式噪音-
The column output circuit is realized by double sample and hold circuit which can effectively decrease fpn ( fixed pattern noise )
列輸出電路採用雙采樣電路,該電路能有效地消除固定模式噪聲。 -
The correlated double sampling ( cds ) circuits structure is used to reduce the fixed pattern noise ( fpn ) of the cmos sensors, and improve the signal - noise ratio ( snr ). the 256 photodiodes arrayed 4 quadrants sensor consists 16x16 active photodiodes array. correlated double sampling processing circuits, output buffer amplifiers and digital control part
針對cmos製造工藝中mos器件固定模式噪聲( fixedpatternnoise , fpn )較大的不足,研究中採用了相關二次采樣( correlateddoublesampling , cds )電路降低固定模式噪聲,從而提高了傳感器的信噪比( signalnoiseratio , snr ) 。
