Abstract

一种图像噪声标定方法和装置、图像降噪方法及装置、图像处理装置(1，9)，所述图像标定方法包括：获取图像传感器(10，90)输出的原始图像数据，所述图像传感器(10，90)包括像敏单元阵列，所述原始图像数据是所述像敏单元阵列在光学黑状态下输出的；基于所述像敏单元阵列输出的原始图像数据确定所述图像传感器(10，90)的固定模式噪声FPN标定数据，所述FPN标定数据用于所述像敏单元阵列的降噪，且所述FPN标定数据的数量小于所述图像传感器(10，90)中像敏单元的数量。所述图像噪声标定方法及装置、图像降噪方法及装置、图像处理装置(1，9)减少了FPN标定数据的数量，所述图像降噪方法及装置、图像处理装置(1，9)预先存储有FPN标定数据，避免每次开机或切换模式时重新确定FPN标定数据。
