Patent ID: 8155190

Claim:
A coding apparatus for applying a coding process to video data on a block-by-block basis while switching between an intra-coding process and an inter-coding process to generate coded data, and outputting the coded data together with strength data indicating a strength of a deblocking filter, comprising: an intra-coding complexity detecting section that detects an intra-coding complexity indicating a complexity of the intra-coding process; an inter-coding complexity detecting section that detects an inter-coding complexity indicating a complexity of the inter-coding process; a characteristic curve calculating section that calculates a characteristic curve indicating a value of the strength data with a data amount per unit time of the 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.
