Patent ID: 8432488

Claim:
A video processing apparatus for converting frame rates of video signals, comprising: a characteristic detection unit that detects, from an input video signal, as characteristics of the video signal, whether or not character information is displayed in the video signal; an image generation unit that uses the characteristics detected by the characteristic detection unit to generate an intermediate frame image having a phase different from a phase of an input frame image of the video signal; and a motion amount detection unit that detects a motion amount of an image by using at least two or more temporally successive input frame images of the video signal, wherein, in accordance with the characteristics detected by the characteristic detection unit, the image generation unit moves the phase of the intermediate frame image to a phase different from a logical interpolation phase determined based on an input frame frequency and an output frame frequency, wherein the image generation unit has: a coefficient generation unit that generates a logical interpolation phase coefficient from the logical interpolation phase that is determined from a phase interval obtained by dividing the input frame frequency by the output frame frequency; a coefficient correction unit that corrects the logical interpolation phase coefficient generated by the coefficient generation unit, in accordance with the characteristics detected by the characteristic detection unit; and a generation unit that generates, from the input frame image, the intermediate frame image having a phase different from the logical interpolation phase, by using the motion amount detected by the motion amount detection unit and the logical interpolation phase coefficient corrected by the coefficient correction unit.
