The present disclosure relates to an image processing device and method capable of preventing a coding efficiency from decreasing. An image processing device comprises: a residual prediction unit for, when a prediction of residual data between an input image consisting of a plurality of components and a prediction image is performed between said components, matching the bit depths of said residual data to each other between said components to perform said prediction; and an encoding unit for encoding the predicted residual data generated according to said prediction by said residual prediction unit. The present disclosure is applicable to, for example, an image encoding device that encodes image data or an image processing device such as an image decoding device that decodes encoded data obtained by encoding image data. |
