摘要

An image decoding method capable of reducing processing load acquires a boundary control flag for controlling both de-blocking filter processing and sample adaptive offset processing on the slice boundaries of a slice to be decoded that is included in an encoded picture (S11), decodes the slice that was to be decoded (S12), performs, on the basis of the boundary control flag, de-blocking filter processing on, out of all slice boundaries for the decoded slice, only the top and left slice boundaries thereof (S13), and performs sample adaptive offset processing in accordance with the boundary control flag on, out of all slice boundaries for the decoded slice, only the top and left slice boundaries thereof (S14).
