摘要： A structure of metadata relevant to a moving image, in which metadata editing is easily performed, comprising a stream data structure including one or more access units each capable of being independently processed; each of said access units has: first data for a reference time point within an access unit time for describing the metadata so as to cause the access unit time to correspond to a moving image time; an object area data describing a spatio-temporal region in the moving image; and second data for specifying a display method relevant to the spatio-temporal region and/or a processing when the spatio-temporal region is designated. The moving image time is to be made to correspond to the access unit time on basis of the reference time point in the first data, so that a period during which at least said second data may be called is specified.

摘要： A wavelength tunable laser diode (LD) is disclosed. The LD provides a SG-DFB region and a CSG-DBR region. The SG-DFB region shows a gain spectrum with a plurality of gain peaks, while, the CSG-DBR region shows a reflection spectrum with a plurality of reflection peaks. The LD may emit light with a wavelength at which the one of the gain peaks and one of the reflection peaks coincides. In the present LD, both the gain spectrum and the reflection spectrum are modified by adjusting the temperature of the SG-DFB region and that of the CSG-DBR region independently.

摘要： According to an embodiment, an image processing apparatus includes a feature data calculator, a generating unit, and an adding unit. The feature data calculator calculates feature data representing changes in pixel values within a first range of an input image. The generating unit obtains a weight of a predetermined image pattern on the basis of a probability distribution and the feature data. The weight represents a pattern of changes in the pixel values. The probability distribution represents a distribution of relative values of feature data of a learning image containing a high-frequency component with respect to feature data of a learning image. The generating unit weights the predetermined image pattern with the weight so as to generate a high-frequency component with respect to the input image. The adding unit adds the high-frequency component to the input image.
