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 pixels surrounding a target pixel of the input image signal, so as to reduce spatial high frequency components of the pixels surrounding the target pixel of the input image signal; a target level setting portion operable to set a predetermined target level; an effect adjustment portion operable to output a correction signal obtained by combining the predetermined target level and the processed signal, the predetermined target level and the processed signal being combined according to an effect adjustment signal for setting an effect of visual processing; and a visual processing portion operable to (i) receive the correction signal and the input image signal, (ii) perform the visual processing on the input image signal, and (iii) output an output signal as a result of the visual processing, the visual processing being performed using the input image signal and the correction signal output by the effect adjustment portion, wherein the visual processing portion performs the visual processing using tone conversion characteristics, such that, when a value of the input image signal is a predetermined value, a corresponding value of the output signal monotonically decreases with respect to a value of the correction signal.
