Method and apparatus for reconstructing content image data

An apparatus for reconstructing content image data, comprising:

• a point selection unit which selects a first point and a second point in a first image of first content and a third point and a fourth point in a second image of second content, the second image being an image corresponding to the first image and the third point and the fourth point being points in an image corresponding to the first point and the second point, respectively;
• a reference vector generation unit which generates a first reference vector using the first point and the second point and generates a second reference vector using the third point and the fourth point;
• an RST value calculation unit which calculates a rotation, scale, and transformation (RST) value from the first image to the second image using the first reference vector and the second reference vector;
• and
• a content reconstruction unit which reconstructs the second content using the calculated RST value.
