Patent number: 10855982Abstract: The present disclosure relates to image processing apparatus and method intended to be capable of suppressing deterioration in image quality. [Solution] A predicated image is generated using inter-prediction and constrained intra-prediction, the inter-prediction using as a reference image an image of a past frame processed before a current frame, the constrained intra-prediction using no neighboring pixels subjected to inter-prediction, the image of the past frame being encoded, stored in a frame memory, read from the frame memory, and then decoded. The present disclosure is applicable to, in one example, an image processing apparatus, an image coding apparatus, or the like.Type: GrantFiled: November 28, 2017Date of Patent: December 1, 2020Assignee: SONY CORPORATIONInventors: Takuya Kitamura, Nobuo Ueki
