Abstract:
The present technology relates to an encoding device and an encoding method, and a decoding device and a decoding method that are capable of reducing the calculation amount of orthogonal transform processing or inverse orthogonal transform processing. A DWT unit ( 91 ) performs a DWT of which the calculation amount is smaller than that of a KLT for residual information. KLT units ( 92 - 0  to  92 - 8 ) perform separable-type KLTs for a low-frequency component of the residual information that is acquired as a result of the DWT using bases of KLTs of the corresponding intra prediction modes. A coefficient acquired as a result of the KLT and a high-frequency component of the residual information that is acquired as a result of the DWT are losslessly encoded. The present technology can be applied to, for example, an image encoding device.

Claim (Index 1):
An encoding device comprising:\n a prior orthogonal transformation unit that performs a second orthogonal transform of which a calculation amount is smaller than a calculation amount of a first orthogonal transform for an image; a posterior orthogonal transformation unit that performs the first orthogonal transform for a low-frequency component of the image that is acquired as a result of the second orthogonal transform; and an encoding unit that encodes the low-frequency component after the first orthogonal transform and a high-frequency component of the image that is acquired as a result of the second orthogonal transform.
