Patent ID: 8665377

Claim:
A video information processing apparatus comprising: a smoothing unit to which input video information of a plurality of pixels is directly inputted, the smoothing unit configured to smooth the input video information and generate smoothed video information; a subtraction unit to which the input video information and the smoothed video information are directly inputted, the subtraction unit configured to calculate a gradation difference between the input video information and the smoothed video information; a mixing unit to which the input video information, the smoothed video information and the gradation difference are directly inputted, the mixing unit configured to mix the input video information and the smoothed video information at a ratio corresponding to the gradation difference and generate mixed video information; a determination unit to which the input video information is directly inputted, the determination unit configured to determine whether or not a peripheral pixel region, including each pixel in the input video information and pixels located around the pixel, is a low frequency region not including a gradation change greater than or equal to a predetermined gradation change; and an output selection unit to which the input video information, the mixed video information and a determination result of the determination unit are directly inputted, the output selection unit configured to output the mixed video information when the determination unit determines that the peripheral pixel region is the low frequency region and output the input video information when the determination unit determines that the peripheral pixel region is not the low frequency region.
