IMAGE ENCODING DEVICE AND METHOD AND IMAGE DECODING DEVICE AND METHOD

摘要

The present disclosure relates to an image encoding device and method and an image decoding device and method, which are capable of suppressing an increase in encoding or decoding workload. A current layer of image data including a plurality of layers is encoded and/or decoded with reference to encoding-related information of some areas, of another layer encoded for each of a plurality of certain areas obtained by dividing a picture, according to control of control information used to control the certain area in which the encoding-related information of the other layer is referred to regarding the current layer of the image data. The present disclosure can be applied to image processing devices such as an image encoding device for performing scalable coding on image data and an image decoding device for decoding an encoded data obtained by performing scalable coding on image data
