Abstract
According to one embodiment, a noise reduction circuit includes a noise reduction filter for converting a pixel value of a pixel of interest through a calculation that uses the pixel value of the pixel of interest and pixel values of adjacent pixels. The noise reduction filter is set, for the calculation, with a heavier weighting for vertically adjacent pixels than that for horizontally adjacent pixels. The horizontally adjacent pixels are adjacent pixels that are located in parallel with the pixel of interest in a horizontal direction. The vertically adjacent pixels are adjacent pixels that are located in parallel with the pixel of interest in a vertical direction.
