Abstract: An encoder includes circuitry and memory. Using the memory, the circuitry: generates a prediction image to be used to encode a current block to be processed; derives a luminance correction parameter by referring to an image region which is included in an image including the current block and is outside the current block; and corrects the prediction image to be used to encode the current block, using the luminance correction parameter. The luminance correction parameter is used in common between a plurality of blocks included in the image.

Abstract: A motion vector derivation unit includes a comparison unit for comparing a parameter TR1 for a reference vector with a predetermined value to determine whether it exceeds the predetermined value or not; a switching unit for switching selection between the maximum value of a pre-stored parameter TR and the parameter TR1 according to the comparison result by the comparison unit; a multiplier parameter table (for multipliers); and a multiplier parameter table (for divisors) for associating the parameter TR1 with a value approximate to the inverse value (1/TR1) of this parameter TR1.

Abstract: A moving picture coding method for coding a picture with switching between frame coding and field coding adaptively on a block-by-block basis includes: determining the maximum number of reference indices for field coding for specifying fields which are to be referred to at the time of field coding, using the maximum number of reference indices for frame coding for specifying frames which are to be referred to at the time of frame coding; and assigning to fields the reference indices for field coding for specifying fields which are to be referred to at the time of field coding, within a range of the determined maximum number thereof, using the reference indices for frame coding for specifying frames which are to be referred to at the time of frame coding.
