Claim One:
1. A scene change determination device for determining a scene change between a plurality of pieces of image data transferred by an interlace method, comprising: a first extraction unit for extracting a plurality of consecutive pixels used for determination from first image data as a group; a second extraction unit for extracting pixels corresponding to the pixels extracted from the first image data, from second image data; an accumulation unit for accumulating differences in value between the corresponding pixels extracted by the first and second extraction units; and a determination unit for determining whether the accumulated value per image data exceeds a threshold value, wherein the first and second extraction units slide and extract a plurality of pixels used for determination for each field of the first and second image data, and if the accumulated value exceeds the threshold value, the determination unit determines that a scene change is detected between the plurality of pieces of corresponding image data.
