Abstract
An image encoding deviceof the present disclosure includes a neighboring pixel non-reference predictorconfigured to generate a predicted image by a predetermined neighboring pixel non-reference prediction for each pixel signal of an original image in a block unit, a filter processorconfigured to perform a low-pass filter process on a prediction signal located at a boundary of a block of the predicted image by using a decoded neighboring signal neighboring to the predicted image under a predetermined control, a prediction residual signal generatorconfigured to generate a prediction residual signal of the block unit by using the predicted image, an orthogonal transformerconfigured to perform an orthogonal transformation process on the prediction residual signal of the block unit under the predetermined control, and an orthogonal transformation selection controllerconfigured to control the filter processorand the orthogonal transformerand generate a predetermined transformation type identification signal. An image decoding deviceof the present disclosure performs a decoding process based on a transformation type identification signal at the time of the predetermined neighboring pixel non-reference prediction.
