Abstract
An image processing device includes a bad pixel masking unit and a noise reduction unit. The bad pixel masking unit detects bad pixels in a plurality of blocks and masks the determined bad pixels. The noise reduction unit removes noise from the pixels in the plurality of blocks excluding the masked pixels using a pattern matching method and corrects bad pixels by obtained an average pixel value.
