IMAGE ENCODING METHOD, IMAGE DECODING METHOD, IMAGE ENCODING DEVICE, AND IMAGE DECODING DEVICE

摘要

An image encoding method for encoding a multiview video is provided. The method includes: determining a maximum number of per-picture pixels and a maximum buffer size which corresponds to a maximum number of candidate reference images for use in a non-multiview coding, based on a level signal representing a coding level with reference to a table; calculating a maximum number of candidate reference views for use in inter-view predictive coding using the maximum number of per-picture pixels, an image size of an input image, and a scale factor for use in multiview video coding; and calculating an MVC maximum buffer size corresponding to a maximum number of candidate reference images for use in multiview video coding, using the maximum number of views, and the maximum buffer size.

1. An image encoding method for encoding a multiview video, comprising:
determining a maximum number of per-picture pixels and a maximum number of candidate reference images which is used in non-multiview coding, from a level signal indicating a coding level with reference to a table indicating a relationship between (i) the coding level, and (ii-i) a maximum number of candidate reference images for non-multiview coding and (ii-ii) a maximum number of per-picture pixels, the maximum number of per-picture pixels indicating a maximum number of pixels per picture and being processable by an image encoding device and an image decoding device; calculating a maximum number of candidate reference views for inter-view predictive coding, using the maximum number of per-picture pixels, an image size of an input image, and a scale factor for multiview video coding; and calculating a maximum number of candidate reference images for multiview video coding, using the maximum number of candidate reference views and the maximum number of candidate reference images for non-multiview coding.
