<p>The present invention relates to an image processing device, an image processing method, and a program that can reduce usage of memory bandwidth when motion compensation operations with fractional precision are performed in inter predictions. A reference image read unit reads predetermined reference pixels from a reference image in an inter prediction so that the number of the predetermined reference pixels corresponding to an outer pixel in a predicted image in the inter prediction is smaller than the number of the predetermined reference pixels corresponding to an inner pixel in the predicted image. Using the read predetermined reference pixels, a 2-tap FIR filter, a 4-tap FIR filter, or a 6-tap FIR filter calculates a pixel having a fractional position in the reference image as a pixel in the predicted image. The present technique can be applied to encoding devices that perform compression encoding by H.264/AVC, for example.</p> |
