摘要： According to one embodiment, a selection unit selects a pixel value to be assigned to a target pixel according to a determination result of a defect determining unit. The defect determining unit performs defect determination according to the level of a signal-to-noise ratio (SNR) estimated by an SNR estimating unit. In the case where the defect determining unit determines that the target pixel is a defect, the selection unit outputs a pixel value according to the level of the SNR.
