Title: IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
Abstract:
The present technology relates to an image processing device and an image processing method which enable an improvement in S/N. A class tap selecting unit configures a class tap by selecting from a first image, obtained by adding a predictive coding residual and a predicted image, a pixel to serve as a class tap to be used for class classification to classify pixels to be processed, in the first image, into a class from among a plurality of classes. A class classifying unit uses the class tap to perform class classification of the pixels to be processed, and a filter processing unit subjects the first image to a filtering process corresponding to the class of the pixels to be processed, to generate a second image to be used to predict the predicted image. The class tap selecting unit updates a tap structure of the class tap to a tap structure selected from among a plurality of tap structures. The present technology can, for example, be applied to image coding devices and decoding devices.
