IMAGE FORMAT DISCRIMINATION DEVICE, METHOD OF DISCRIMINATING IMAGE FORMAT, IMAGE REPRODUCING DEVICE AND ELECTRONIC APPARATUS

摘要

An image format discrimination device includes a correlation candidate extraction unit that obtains a gradient amount of each pixel position, based on pixel data of a horizontal line of input image data and extracts as a correlation candidate, a pixel of a position where a sign of the gradient amount is changed; a correlation inspection unit that inspects whether or not a first correlation candidate range and a second correlation candidate range having correlation to each other in the horizontal line are present, based on the correlation candidate that is extracted by the correlation candidate extraction unit; and a discriminating image format unit that discriminates whether or not the input image data are three-dimensional image data of a side-by-side type, based on the inspection result of the correlation inspection unit.
