Abstract:
1. A visual processing device, comprising: a spatial processing portion operable to output a processed signal generated by performing predetermined spatial processing on an input image signal based on information from a plurality of pixels surrounding a target pixel of the input image signal; and a visual processing portion operable to perform visual processing using the input image signal and the processed signal, and operable to output an output signal as a result of the visual processing, the visual processing being performed using the input image signal and the processed signal output by the spatial processing portion, so as to enhance a local contrast of the input image signal, wherein the visual processing portion reduces an effect of the enhancement of the local contrast with respect to a flat region in the input image signal, the flat region being proximal to a detected edge of the input image signal and determined based on a range of the plurality of pixels surrounding the target pixel.
