IMAGE PROCESSING DEVICE AND METHOD
First Claim
1. An image processing device comprising:
- a decoding unit configured to decode encoded data obtained by lossy encoding an image of a frame encoded already which is used as a reference image in encoding of an image of a current frame and perform rounding of a decoded image obtained by the decoding with a rounding value whose value is changed over in a time direction of the image.

Abstract
The present disclosure relates to an image processing device and method that can suppress deterioration of the picture quality by encoding. The image processing device includes a decoding unit configured to decode encoded data obtained by lossy encoding an image of a frame encoded already which is used as a reference image in encoding of an image of a current frame and perform rounding of a decoded image obtained by the decoding with a rounding value whose value is changed over in a time direction of the image. The present disclosure can be applied, for example, to an image processing device, an image encoding device or the like.
