Image encoding device, image decoding device, and program thereof

An image decoding device for decoding a signal encoded by block-dividing a frame constituting a moving image, the image decoding device comprising:

• a predictor circuitry configured to generate a predicted image of block unit including a prediction signal by a predetermined prediction that performs a signal prediction for each pixel signal of an original image of the block unit;
• a corrector circuitry configured to
• acquire a control identification signal indicating a type of transformation process selected by an encoding side,
• control, based on the control identification signal, an execution and a non-execution of a modifying process on a prediction signal of a block of the predicted image, and
• generate a block of a new predicted image by performing the modifying process by using a decoded neighboring signal neighboring to the block of the predicted image when executing the modifying process;
• an inverse quantizer circuitry configured to reconstruct a transformation coefficient signal by performing a corresponding inverse quantization process on a transformation coefficient quantized by a predetermined quantization process as a signal encoded by block-dividing a frame constituting the moving image;
• and
• an inverse transformer circuitry configured to reconstruct a prediction residual signal of the block unit by controlling an inverse transformation process determined based on the control identification signal with respect to the reconstructed transformation coefficient signal.
