Image conversion method and image conversion apparatus |
摘要 |
An image conversion apparatus includes a progressive scanning converter for receiving an input image as a first interlaced scanning image having a field frequency of m (m: integer not less than 2) fields/sec, and converting the first interlaced scanning image into a first progressive scanning image having a frame frequency of m frames/sec; a frame frequency converter for converting the first progressive scanning image into a second progressive scanning image having a frame frequency of n (n: integer not less than 1) frames/second, by thinning the first progressive scanning image in frame units; and an interlaced scanning converter for converting the second progressive scanning image into a second interlaced scanning image having a field frequency of 2n fields/sec, and outputting the second interlaced scanning image.
