Abstract: This disclosure describes techniques for coding 3D video block units. In one example, a video encoder is configured to determine a first real-world depth range for a first depth view component comprising a reference view component, determine a second real-world depth range for a second depth view component comprising a current view component, wherein the current view component is predicted relative to the reference view component, determine a predictive block for a portion of the current view component from the reference view component, adjust values of the predictive block based on a difference between the first real-world depth range and the second real-world depth range, and predict the portion of the current view based on the adjusted values of the predictive block.
