Abstract:
1. An apparatus comprising: a converter that generates a progressive image from a first field image and a second field image prior to the first field image by using a conversion method, wherein the conversion method includes (a) determining a difference between an average value of pixels at both sides of a first pixel in the first field image and a pixel value of a second pixel which is in the second field image and corresponds to the first pixel, (b) generating the first pixel based on the average value to generates the progressive image if the difference exceeds a predetermined value, and (c) generating the first pixel based on the second pixel to generates the progressive image if the difference does not exceed the predetermined value; a reduced image generating unit that generates a reduced image from the progressive image; a second motion vector detecting unit that detects a second motion vector based on the reduced image; and a first motion vector detecting unit that detects, from a search area, a first motion vector corresponding to a target block included in the first field image, wherein the search area is determined based on the second motion vector.
