    摘要: Since there is a case where reproduction of metadata is limited according to the processing power of a reproduction apparatus or the designation from a user, the invention provides a data structure in which metadata whose preferential reproduction is desired can be selected and reproduced. The metadata relevant to a moving image includes a stream data structure including one or more access units each being a data unit which can be independently processed, and each of the access units includes first data to specify an effective period defined with respect to a time axis of the moving image, object area data describing a spatio-temporal region in the moving image, second data including one of or both of data to specify a display method relevant to the spatio-temporal region and data to specify a processing to be performed when the spatio-temporal region is specified, and third data to specify, in a case where one or more access units exist on a same screen in the moving image at a time of reproduction of the metadata, reproduction priority of each of the access units.

    摘要: According to one embodiment, an image processing apparatus includes a difference calculation unit, an intensity calculation unit, and an enhancing unit. The difference calculation unit calculates, for each partial area of an input image, a difference between a depth value of a subject and a reference value representing a depth as a reference. The intensity calculation unit calculates for each partial area an intensity, which has a local maximum value when the difference is 0 and has a greater value as the absolute value of the difference is smaller. The enhancing unit enhances each partial area according to the intensity to generate an output image.

    摘要: According to one embodiment, an image processing device includes an obtaining unit, a separating unit, a processing unit and a combining unit. The obtaining unit obtains a depth value of a subject imaged on an input image. The separating unit separates the input image into a first component that is a component including a gradation and a second component that is a component other than the first component. The processing unit enhances the first component in accordance with the depth value to generate a processed component. The combining unit combines the processed component and the second component to generate a combined component.
