Abstract
A coding apparatus includes: an intra-coding complexity detecting section that detects an intra-coding complexity indicating a complexity of an intra-coding process; an inter-coding complexity detecting section that detects an inter-coding complexity indicating a complexity of an inter-coding process; a characteristic curve calculating section that calculates a characteristic curve indicating a value of strength data indicating the strength of a deblocking filter with a data amount per unit time of coded data as a variable, on the basis of the intra-coding complexity and the inter-coding complexity; and a strength value calculating section that calculates a value of the strength data by substituting a data amount of the coded data into the characteristic curve.
