Abstract: An image processing apparatus and a method are proposed to control the disparity and rate of disparity change in a 3D image. The method includes the following steps: inputting a maximum negative disparity threshold value and/or a maximum rate threshold value of disparity change by a viewer; receiving data of a 3D image; decoding the data into left eye image data and right eye image data; determining a maximum negative disparity and a rate of disparity change of the decoded 3D image data; determining and image movement value based on the determined maximum negative disparity and rate of disparity change and at least one threshold value; adjusting the left eye image and the right eye image using the image movement value; and displaying the adjusted left eye image and right eye image to a viewer on a 3D display device. The apparatus comprises image receiver, image decoder maximum disparity analyzer disparity control value determiner, user interface, disparity adjuster, and stereo display.

Abstract: It is provided a method for providing a main 3D content and a supplementary content used in a 3D multimedia device. The method comprises the steps of displaying the main 3D content; and triggering the supplementary content by a 3D related event of the main 3D content, wherein, depth value of the supplementary content is updated along with depth value change of the main 3D content.

Abstract: It provides a method for encoding a set of elements by using components defining the structure of each of the set of elements, wherein each element comprises data structure information and at least one data value. The method comprises the steps of: selecting a current element for encoding; determining whether the current element has the same data structure information as a previously encoded element; in the negative, encoding the data structure information of the current element and the at least one data value of the current element; and in the affirmative, encoding the at least one data value of the current element and providing an indication value associated with the current element indicating the current element has the same data structure information as said previously encoded element. The method is used to reduce the encoding redundancy of the structure information.
