Claim One:
1. A method for determining whether an image file contains three-dimensional content, the method comprising: receiving an image file that may contain two- or three-dimensional content; analyzing the image file to determine whether the image file has characteristics consistent with the image file containing three-dimensional content, the analysis comprising analyzing data compression efficiency of the image file by: identifying a data compression technique used to compress the image file; determining a data compression ratio achieved by the data compression technique when compressing the image file; comparing the data compression ratio to a threshold; and determining that the image file has characteristics consistent with the image file containing three-dimensional content responsive to the comparison of the data compression ratio to the threshold; responsive to a determination that the image file has characteristics consistent with the image file containing three-dimensional content, determining whether the image file contains three-dimensional content in a first format, wherein the first format comprises at least one of a side-by-side format, a top-bottom format, and an interleaved format by: iteratively analyzing individual image frames in the image file to determine similarity values; for each iteration, classifying the image frame as stereoscopic if the similarity value indicates that the image frame contains images that correspond to different perspectives of a common scene and as non-stereoscopic if the similarity value indicates that the image frame does not contain images that correspond to different perspectives of a common scene, to obtain N classifications of N image frames in the image file, wherein N>1; and determining whether the image file contains three-dimensional content in the first format based on the N classifications of the N image frames; and if the determination of whether the image file contains three-dimensional content in the first format indicates that the image file contains three-dimensional content in the first format, providing an indication that the image file contains three-dimensional content by notifying a display device that the image file contains three-dimensional content in the first format.
