Image scaling

摘要

The present invention relates to an apparatus, method for adjusting depth characteristics of a three-dimensional image for correcting for errors in perceived depth when scaling the three-dimensional image, the method comprising: 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; determining at least one shifting factor for varying the depth characteristics, the at least one shifting factor indicative of a relative shift to be applied between the first and the second images, wherein the at least one shifting factor is determined in accordance with the scaling factor and at least one depth parameter derived from the depth characteristics; and performing 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.

1. A method for adjusting depth characteristics of a three-dimensional image for correcting for errors in perceived depth when scaling the three-dimensional image, the method comprising:
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; determining 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 performing 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; wherein the at least one depth parameter used to determine the shifting factor relates to a variation in the depth of the stereoscopic image; wherein the variation corresponds to an average variation in the depth of the stereoscopic image; and wherein the average variation is determined in a depth domain and transformed to a disparity domain for determining the shifting factor.
