Image Scaling

An apparatus for adjusting depth characteristics of a three-dimensional image for correcting for errors in perceived depth when scaling the three-dimensional image, the apparatus comprising:

• an input port arranged to receive three-dimensional image information comprising a stereoscopic image including a first image and a second image, the stereoscopic image having depth characteristics associated with an offset of the first and second images;
• and
• a processor arranged to:
• determine a scaling factor indicative of a scaling for converting the stereoscopic image from an original target size to a new size;
• determine a shifting factor for varying the depth characteristics, the shifting factor indicative of a relative shift to be applied between the first and the second images, wherein the shifting factor is determined in accordance with the scaling factor and at least one depth parameter derived from the depth characteristics;
• and
• perform the relative shift between the first and second images in accordance with the shifting factor for adjusting the offset of the first and second images.
