<p>The present invention relates to adjusting depth characteristics of a three-dimensional image for correcting for errors in perceived depth when scaling the three-dimensional image. It comprises receiving 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; determining a scaling factor indicative of a scaling for converting the stereoscopic image from an original target size to a new size and determining at least one shifting factor for varying the depth characteristics. The shifting factor indicates the relative shift to be applied between the first and the second image and is determined in accordance with the scaling factor and at least one depth parameter derived from the depth characteristics. 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 is then applied to the images. The depth parameter used relates to the variation in the depth of the stereoscopic image and is determined based on the maximum and minimum disparity of the image. The image may be divided into regions with each region having its own associated shift factor. Furthermore the depth parameters may be determined from a depth map either included with the image or generated from the image.</p> |
