Summary:In one embodiment, an image processor includes: a decoder configured to decode a coded moving image signal, and generate a decoded moving image signal; an output module configured to output a picture type of a field or a frame of the decoded moving image signal; a detector configured to detect an inter-frame difference of the field or the frame of the decoded moving image signal at least every time the output picture type is changed; a flicker reduction module configured to reduce flicker noise included in the decoded moving image signal by using the decoded moving image signal of a plurality of the fields and frames; and a controller configured to control a strength of the reduction effect of the flicker noise with respect to the field or the frame of a same picture type as the changed picture type based on the inter-frame difference.
