【Disparity analysis of Hollywood 3D films】

It has been pointed out that the establishment of particular know-how is the key for producing 3D content. Here “know-how” means presenting depth sensation mainly by imposing binocular disparity, and it has been the advance in Hollywood.

AIS-J research sub-committee has carried out multifaceted and continuous analysis of the disparity in well-known 3D films produced in Hollywood and highly evaluated throughout the world. The objective is to obtain useful knowledge for producing 3D content in the future, by quantitatively determining the characteristics and trends in the disparity in these works.

Disparity analysis was carried out for the following five 3D films. In each case the pixel disparity was determined using the Blu-ray version that assumes viewing at home.

• Avatar (20th Century Fox, 2009)
• Cloudy with a Chance of Meatballs (Sony Pictures, 2009)
• Coraline (Focus Features, 2009)
• Tangled (Walt Disney Pictures, 2010)
• How to Train Your Dragon (DreamWorks Animation, DWA, 2010)

Current results of the study were published as the following conference paper:
