Abstract: Provided are a data structure including a header area, and a payload area comprising data, a method of generating the data structure, and extracting information from the data structure. At least one of the header area and the payload area includes at least one sub-area in which one or more signal fields are included. At least one signal field among the signal fields includes information for signalling presence or absence of one or more information fields located at least partly in the data structure, the one or more information fields corresponding to the one or more signal fields.

Abstract: Image processing comprises receiving content from an application; rendering the content into a rendered frame and storing the rendered frame in a frame buffer; transferring the rendered frame from the frame buffer to a compositor, and displaying the rendered frame using the compositor. The image processing further comprises applying a non-linear transformation to at least part of the rendered frame during the rendering the content into the rendered frame; during the transferring of the rendered frame to the compositor, or during the displaying of the rendered frame by the compositor.

Abstract: An image processing method is disclosed, comprising comparing a first image and a modified second image, the modified second image comprising a copy of the first image in which at least one pixel value of one or more pixels have been modified, and based on the result of the comparison, generating first image reconstruction information which can be combined with the modified second image to reconstruct the first image. A corresponding image reconstruction method comprises combining the image reconstruction information with the modified second image to reconstruct the first image. Apparatus for implementing the methods is also disclosed.

Abstract: An image processing method is provided. The image processing method includes detecting a face of an object present on an image, obtaining at least one feature from the detected face as at least one facial parameter and obtaining at least one context related to the image as at least one contextual parameter, determining a manipulation point for manipulating the detected face, based on the obtained at least one facial parameter and the obtained at least one contextual parameter, and manipulating the image based on the determined manipulation point.

Abstract: Provided is a method of managing power of an electronic device. The method includes: obtaining operation information related to an operation from among operations performed by the electronic device. The operation is recognizable to a user via a product of hardware processing performed by hardware included in the electronic device. The method also includes obtaining load information related to a load generated by the operation performed by the electronic device. In addition, the method includes performing power management on the hardware included in the electronic device based on the operation information and the load information.

Abstract: A method for mapping cells onto symbols is provided. The cells include two or more cells processed by pre-coding in groups, the symbols include N symbols in a time-sequence, and each symbol includes M carriers in a frequency-order. The method comprises: mapping each cell to a carrier of a symbol; and frequency interleaving the carriers of each symbol. The mapping and the frequency interleaving are performed such that, following the frequency interleaving, the cells of a group of pre-coded cells are each mapped to carriers having the same carrier frequency or to carriers having carrier frequencies differing by no more than a threshold.
