Abstract
An imaging device includes a frame rate conversion unit synthesizing images captured at a second frame rate higher than a first frame rate to convert the images into a synthesized image having the first frame and a motion estimation unit performing motion estimation between consecutive frames of the images captured at the second frame. The imaging device also includes a motion vector synthesis unit synthesizing motion vectors having the second frame rate, to generate a synthesized motion vector of a target macroblock in the synthesized image, a motion blur amount determination unit counting, in an area surrounding the target macroblock, the number of macroblocks having the same synthesized motion vector as the target macroblock and comparing a value derived from the number of counted macroblocks with a threshold value, and a motion vector selection unit selecting the synthesized motion vector when the derived value determined to exceed the threshold value.
