Patent ID: 8421850

Claim:
An image processing apparatus comprising: a motion-vector detection section configured to find a motion vector corresponding to an image disparity existing between left and right eyes to appear as a disparity in images for a case in which an input image signal supplied to said image processing apparatus in accordance with a field sequential system is regarded as a signal of a 3-dimensional image format on a basis of first, second and third images appearing consecutively along a time axis in said input image signal; and a format determination section configured to determine whether said input image signal is a signal of said 3-dimensional image format or a signal of a 2-dimensional image format and determine whether a currently received image represented by said input image signal is an image for the left eye or an image for the right eye if said input image signal is determined to be a signal of said 3-dimensional image format, wherein said motion-vector detection section detects a first motion vector between said first image and said third image, and detects a second motion vector between any two images selected from said first to third images as two adjacent images appearing consecutively along the time axis, and wherein said format determination section determines whether or not there is a correlation between said first motion vector and said second motion vector and, based on a result thereof, determines whether the format of said input image signal is said 2-dimensional image format or said 3-dimensional image format.
