Abstract:
An image coding apparatus configured to divide an image into one or more slices each including a plurality of blocks and to code each slice on a block-by-block basis includes a first coding unit configured to code blocks included in a first portion of the slice, and a second coding unit configured to code blocks included in a second portion of the slice, wherein, when the second coding unit codes an initial block in the second portion, the second coding unit codes the initial included in the second portion by referring to a first quantization parameter provided to the slice as an initial value and referred to by the first coding unit when the first coding units codes the initial block in the first portion.

Claim (Index 9):
An image decoding apparatus which decodes image data from a bitstream, the image decoding apparatus comprising:\n a derivation unit configured to derive quantization parameters based on difference values decoded from the bitstream; and a decoding unit configured to decode the image data using the quantization parameters, wherein the derivation unit is configured:\n to derive a first quantization parameter of a first line in a slice by adding a difference value to a slice quantization parameter, wherein the difference value is a difference value between the slice quantization parameter and the first quantization parameter of the first line, and wherein the slice quantization parameter is provided to the slice; \n to derive an n-th (n is an integer equal to or greater than 2) quantization parameter of a second line in the slice by adding a difference value to an (n\u22121)-th quantization parameter of the second line, wherein the difference value is a difference value between the (n\u22121)-th quantization parameter of the second line and the n-th quantization parameter of the second line; and \n to derive a first quantization parameter of the second line by adding a difference value to the slice quantization parameter, wherein the difference value is a difference value between the slice quantization parameter and the first quantization parameter of the second line.
