A video-information-processing apparatus comprising: a smoothing unit to smooth input video information of a plurality of pixels and generate smoothed video information; a subtraction unit to calculate a gradation difference between the input and smoothed video information; a mixing unit to mix the input and smoothed video information at a ratio corresponding to the difference and generate mixed video information; a determination unit 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 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.

Video information processing apparatus and recording medium having program recorded therein

An image signal processing apparatus for converting an interlace signal which creates a frame image by alternately displaying an odd field and an even field on a single screen into a progressive signal, includes a line memory for storing the interlace signal, a writing/reading portion for writing/reading the interlace signal into/from the line memory, a signal generation portion for generating a prescribed signal, a selector for selectively outputting the interlace signal from the line memory or the prescribed signal from the signal generation portion, and a controller for controlling signal selection by the selector.
