An electrical apparatus to reduce noise and minimize a drop in resolution. A recording unit records a processing target frame image and prior and future frame images; a first pixel-extracting section extracts pixels in a prescribed region; a second pixel-extracting section extracts pixels in a region corresponding to the prescribed region in the prior and future frame images; a first distance calculating section calculates temporospatial distances; a second distance calculating section calculates inter-pixel-value distances; and a noise reduction section reduces the processing target frame image on the basis of the temporospatial distance and the inter-pixel-value distance.
