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.

Claims

1-41. -41. (canceled)

42. A visual processing device for performing a visual processing on an inputted image signals and outputting the signal performed by the visual processing, comprising:

a spatial processing portion operable to perform a predetermined spatial processing on the inputted image signal using pixels surrounding a target pixel and output a processed signal;

an effect adjustment portion operable to output a correction signal obtained by correcting the processed signal, according to an effect adjustment signal for setting the effect of visual processing; and

a visual processing portion operable to receive the correction signal and the image signal and perform the visual processing on the image signal to output an output signal.

43. A visual processing method comprising:

performing a predetermined spatial processing on the inputted image signal using pixels surrounding a target pixel and outputting a processed signal;

outputting a correction signal obtained by correcting the processed signal, according to an effect adjustment signal for setting the effect of visual processing; and

receiving the correction signal and the image signal and performing the visual processing on the image signal to output an output signal.
