Abstract: A visual processing device, display device, visual processing method, program, and integrated circuit that change a strength of visual processing of an image in real-time. A spatial processing portion ( 2 ) creates an unsharp signal US from an input signal IS. A target level setting portion ( 4 ) sets a predetermined target level value L for setting a range according to which the strength of the visual processing is adjusted. An effect adjustment portion ( 5 ) creates a synthesized signal MUS by synthesizing the predetermined target level value L and the unsharp signal US in accordance with an effect adjustment signal MOD that has been set externally. A visual processing portion ( 3 ) outputs an output signal OS in accordance with the input signal IS and the synthesized signal MUS, making it possible to change the strength of the visual processing.
