Title:
IMAGE CODING DEVICE, IMAGE CODING METHOD AND IMAGE CODING PROGRAM, AND IMAGE DECODING DEVICE, IMAGE DECODING METHOD AND IMAGE DECODING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/198626
Kind Code:
A1
Abstract:
Provided is an image coding device for dividing images into blocks and performing coding in units of divided blocks. A primary signal block dividing unit (101) divides a primary signal of an image into rectangles of a predetermined size to generate primary signal blocks. A secondary signal block dividing unit (101) divides a second signal of an image into rectangles of a predetermined size to generate secondary signal blocks. A primary signal prediction unit (102) predicts the primary signal, and a secondary signal prediction unit (102) predicts the secondary signal. The secondary signal prediction unit (102) is capable of inter-component prediction for predicting the secondary signal from the coded primary signal, and limits the inter-component prediction on the basis of the size of the primary signal blocks and/or the size of the secondary signal blocks.
