Title:
An image decoding device, an image decoding method, and a program
Document Type and Number:
Japanese Patent JP6066945
Kind Code:
B2
Abstract:
An image decoding apparatus updates the value of a register holding the value of a coded block flag (CBF) at high speed. The image decoding apparatus initializes all the values of registers holding the values of CBFs to a predetermined initial value, before starting processing on each coding tree unit (CTU) in a picture. Only in a case where the value of a decoded CBF is different from the initial value, the image decoding apparatus updates the value of a register to the value of the decoded CBF.
