Abstract

An image capturing device (1) includes: a pixel value fluctuation amount calculation unit (102) that calculates a pixel value fluctuation amount (d(i)[F]) as a fluctuation amount of each of pixel values in a time direction; a line fluctuation amount calculation unit (103) that calculates a line fluctuation amount (ave(i)[F]) as an average value of the pixel value fluctuation amounts of pixels in a partial line; a variance value calculation unit (104) that calculates a variance value (var(i)[F]) of the pixel value fluctuation amounts from the pixel value fluctuation amounts and the line fluctuation amount; a movement adaptive weight determination unit (114) that calculates a movement adaptive weight (w(i)[F]) based on the variance value; a correction amount calculation unit (111) that calculates a line fluctuation noise correction amount (c_lfn(i)[F]), corresponding to each of the pixel values outputted from the image capturing unit (20), from the line fluctuation amount and the movement adaptive weight; and a line fluctuation noise correction unit (112) that corrects each of the pixel values outputted from the image capturing unit by using the line fluctuation noise correction amount and thereby generates an image signal after the correction.
