Summary:To provide an image processing device capable of reducing the amount of calculation related to a recovery process when the recovery process of an image is performed by applying a neural network after decoding.SOLUTION: An image processing device according to an embodiment includes acquisition means that acquires the degree of deterioration of each block in a coded image in which an input image is encoded, decoding means that decodes the coded image, and recovery means that performs image recovery processing on a predetermined block in the decoded image decoded by the decoding means. Then, the recovery means switches whether to perform the image recovery processing using a first neural network for each block in the decoded image according to the degree of deterioration of each block in the coded image.SELECTED DRAWING: Figure 3 【課題】復号化後にニューラルネットワークを適用して画像の回復処理を行う際に、当該回復処理に係る演算量を低減させることが可能な画像処理装置を提供する。【解決手段】実施形態に開示する画像処理装置は、入力画像に対して符号化を施した符号化画像におけるブロックごとの劣化の度合いを取得する取得手段と、符号化画像を復号化する復号化手段と、復号化手段により復号化された復号化画像における所定のブロックに画像の回復処理を施す回復手段と、を有する。そして、回復手段は、符号化画像におけるブロックごとの劣化の度合いに応じて、復号化画像におけるブロックごとに第1のニューラルネットワークを用いた画像の回復処理を施すか否かを切り替える。【選択図】図3
