Image Decoding Apparatus Binary Tree Division Logic

The patent applies dynamics by making the division method adaptive rather than fixed. The apparatus dynamically selects between QT and BT division methods based on the specific characteristics of each coding node, allowing the system to adapt to different image content requirements while maintaining manageable complexity through conditional logic rather than exhaustive processing of all possible division patterns

The patent applies local quality by allowing different division methods (QT or BT) to be applied to different coding nodes based on their local characteristics. Instead of using a uniform division approach across the entire image, the system evaluates and applies the most appropriate division method locally at each coding node, improving overall efficiency without requiring complex global optimization

The patent uses dynamics to selectively apply division patterns based on local image characteristics rather than exhaustively processing all possible patterns. The apparatus dynamically determines the optimal division method (QT or BT) for each coding node, achieving high coding precision where needed while avoiding unnecessary complexity in regions where simpler division suffices

The patent applies partial action by not implementing all possible division patterns uniformly across the entire image. Instead, it selectively applies QT and BT division only where beneficial, avoiding the excessive complexity that would result from supporting and processing every possible division pattern in every coding node
