Patent ID: 8611416

Claim:
An encoding mode decision apparatus using a temporal complexity comprising: a temporal complexity calculator to calculate a temporal complexity by using Hadamard transforming block residuals to obtain temporal block complexity in accordance with the following equation: Temporal ⁢ ⁢ Block ⁢ ⁢ Complexity = ( ∑ i = 0 n ⁢ Block_Complexity ⁢ ( i ) ) / Q_step where ⁢ ⁢ n ⁢ ⁢ is ⁢ ⁢ a ⁢ ⁢ number > zero ⁢ ⁢ and < or ⁢ ⁢ equal ⁢ ⁢ to ⁢ ⁢ 15 ; with the temporal block complexity being divided by a quantization width; and further comprising a mode decider to decide the encoding mode utilizing the temporal complexity.
