Image processing method and apparatus therefor
First Claim
1. An image processing method, comprising:
- extracting shot information included in metadata of a video data, the shot information classifies frames of the video data into shot units, each shot unit being a group of frames having a similar composition with resect to a previous frame;
determining whether frames of a predetermined shot can be reproduced as a three-dimensional image format based on shot type information included in the shot information, the shot type information indicates whether the frames of the predetermined shot need to be output as a two-dimensional image format or the three-dimensional image format;
extracting background depth information from the metadata if the frames of the predetermined shot unit can be reproduced as the three-dimensional image format, wherein the background depth information relates to a background of the frames of the predetermined shot unit;
generating a depth map about the background of the frames based on the background depth information;
if the frames of the predetermined shot unit comprise an object, extracting object depth information about the object from the metadata; and
generating a depth map about the object based on the object depth information.

Abstract
An image processing method, including extracting shot information from metadata, wherein the shot information is used to classify a series of two-dimensional images into predetermined units; if it is determined, by using shot type information included in the shot information, that frames classified as a predetermined shot can be reproduced as a three-dimensional image, extracting background depth information from the metadata, wherein the background depth information is about a background of the frames classified as the predetermined shot; generating a depth map about the background of the frames by using the background depth information; if the frames classified as the predetermined shot comprise object, extracting object depth information about the object from the metadata; and generating a depth map about the object by using the object depth information.

17. An image processing apparatus, comprising:
-
a metadata analyzing unit configured to extract shot information included in metadata of a video data, the shot information classifying frames of the video data into shot units, each shot unit being a group of frames having a similar composition with respect to a previous frame, to extract shot type information included in the shot information for determining whether frames of a predetermined shot unit can be reproduced as a three-dimensional image format, to extract background depth information from the metadata when frames of the predetermined shot unit can be reproduced as a three-dimensional image format, the background depth information relating to a background of the frames of the predetermined shot unit, and to extract and analyze object depth information about an object from the metadata when the frames of the predetermined shot unit include the object; and a depth map generating unit configured to generate a depth map about the background of the frames based on the background depth information, and configured to generate a depth map about the object based on the object depth information. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 34)
