摘要

The disclosed filter coefficient encoding device, which encodes the residual of the filter coefficients of an object filter that acts on an object image and predicted values of said filter coefficients, is provided with a filter coefficient prediction unit (140') that generates the abovementioned predicted values by means of multiplying weighting factors and each filter coefficient of a reference filter that acts on a reference image, and the filter coefficient prediction unit (140') is configured in a manner so that the weighting factors multiplied to the filter coefficients in the peripheral section are smaller than the weighting factors multiplied to the filter coefficients in the central section.
