Abstract: A decoder that decodes a current block using a motion vector includes: a processor; and memory. Using the memory, the processor: derives a first candidate vector from one or more candidate vectors of one or more neighboring blocks that neighbor the current block; determines, in a first reference picture for the current block, a first adjacent region that includes a position indicated by the first candidate vector; calculates evaluation values of a plurality of candidate regions included in the first adjacent region; and determines a first motion vector of the current block, based on a first candidate region having a smallest evaluation value among the evaluation values. The first adjacent region is included in a first motion estimation region determined based on the position indicated by the first candidate vector.

Abstract: A color correcting device effects color correction of designated color digital data (DMAIN0-DMAIN7) in consideration of two of reference color digital data (Din10-Din17, Din20-Din27). The designated color digital data is data of a designated one of three primary colors. The two of the reference color digital data are data of remaining two of the three primary colors. A first memory (43, 61-63) stores auxiliary data (DSUB0-DSUB9) of which an address is a respective combination of the two of the reference color digital data. A second memory (44, 64-66) stores corrected data (DiOUT0-DiOUT7) of the designated color, an address of the corrected data being a respective combination of the auxiliary data and the designated color digital data. A read controller (32) provides the first memory with the two of the reference color digital data, and provides the second memory with the auxiliary data read from the first memory and the designated color digital data, to read the corrected data of the designated color.
