PRNU (Pixel response non uniformity) Correction

이미지  센서  제조과정에서  각  픽셀은  미세한  차이가  발생하고,  이로  인해  빛에  대한  응답특성의
차이가  발생한다.
PRNU Correction  기능은  각  픽셀의  응답특성을  보정하여,  균일한  이미지를  획득할  수  있다.
보정  데이터는  제품  출하  시  기본  값이  디바이스  내부의  비휘발성  메모리에  저장되며,  이미지  센
서  고유의  특성이므로  각  제품마다  별도의  보정  데이터가  저장된다.
다음의  그림은  PRNU  보정  전/후  이미지를  나타낸다.

Figure 23. PRNU Correction
