Method for Low-Latency Illumination Compensation Process and Depth Lookup Table Based Coding

An apparatus for illumination compensation in a three-dimensional (3D) and multi-view coding system, the apparatus comprising one or more electronic circuits configured to:

• receive a current picture or slice in a dependent view;
• determine whether to enable or disable the illumination compensation for the current picture or slice based on a condition related to statistic associated with a selected reference picture or slice respectively, or related to high-level coding information associated with the current picture or slice respectively, wherein the high-level coding information associated with the current picture or slice excludes any information related to depth values of the current picture or slice respectively;
• if the illumination compensation is enabled, apply the illumination compensation to the current picture or slice respectively;
• and
• if the illumination compensation is disabled, skip the illumination compensation for the current picture or slice respectively.

A method of depth coding using a depth lookup table (DLT) in a three-dimensional (3D) and multi-view coding system, the method comprising:

• receiving a current depth picture or slice;
• determining the DLT and determining whether to enable or disable DLT coding using the DLT for the current picture or slice based on a condition related to statistic associated with selected reference pictures or slices respectively;
• if the DLT coding is enabled, applying the DLT coding to the current picture or slice respectively;
• and
• if the DLT coding is disabled, skipping the DLT coding for the current picture or slice respectively.
