Title:
IMAGE CODING METHOD AND IMAGE ENCODER
Document Type and Number:
Japanese Patent JP2017192144
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an image coding method capable of improving processing efficiency.SOLUTION: An image coding method includes a step of transmitting a bit stream containing a dependent slice activation flag indicating whether a dependent slice, coding of which is performed depending on the results of coding for a slice other than the processing object slice, is included in a picture or not, a slice address indicating the start position of a processing object slice, and a dependent indication indicating whether or not the processing object slice is a dependent slice. The dependent slice activation flag is placed in a parameter set common to multiple slices, the slice address is placed in the slice header of the processing object slice, and the dependent indication is placed before the slice address and after a syntax element for identifying the parameter set in the slice header.SELECTED DRAWING: Figure 13
