Abstract:
A method for generating image data includes adjusting an angle formed by each of a plurality of lenses attached to the imaging device relative to a reference plane based on a photography mode, obtaining at least one first image data using the plurality of adjusted lenses, and generating second image data corresponding to the photography mode using the at least one first image data.
Abstract:
Provided is an apparatus and method for obtaining a high dynamic range (HDR) image. The apparatus includes an image sensor generating a first image by applying different exposure times for units of different predetermined regions, an image separating unit separating the first image into images, each of which is composed of regions having an identical exposure time, an image restoring unit restoring the separated images in such a way that each of the separated images has a resolution that is the same as a resolution of the first image, and an image synthesizing unit synthesizing the restored images into a second image.
Abstract:
A method of and an apparatus for copying and decrypting encrypted digital data. The method of copying encrypted digital data includes encrypting a first media key block to be used for decryption of the encrypted digital data using a predetermined key of a second information storage medium and storing the encrypted digital data and the encrypted first media key block in the second information storage medium. Security of data encryption is heightened by not discarding an encryption key used for an initial encryption, encrypting the encryption key used for initial encryption using another encryption key used for a second encryption, and storing the encrypted encryption key with the data. Also, since unnecessary decryption and encryption of data are not repeated, the time required for copying data is reduced, and since data is transferred between apparatuses in an encrypted state, a security level is higher.
Abstract:
A method of controlling a power supply of a digital TV with a function of executing applications is provided. According to the method, in a digital TV apparatus with the application executing function, a power supply of a general-purpose CPU platform which processes data required for executing an application and a power supply of a decoding unit which decodes digital broadcasting data and outputs the decoded data on a screen are controlled separately.
Abstract:
A method and apparatus for overlaying broadcast video with application graphics in a digital TV having an application-execution function are provided. The apparatus includes a decoding unit which decodes a received digital broadcast signal and outputs a video signal, a memory unit which stores graphic data used for the application, and an embedded central processing unit (CPU) comprising a video processor which overlays the video signal directly received through a dedicated input port from the decoding unit with the graphic data stored in the memory unit, so that the overlaid result makes one screen.
Abstract:
A method of providing a photo development service in a digital TV and an apparatus therefor are provided. The method includes, automatically displaying part or all of the photo images on the screen if an external storage medium storing photo images is connected to a digital TV, and transmitting an image selected by a user from among the displayed images to a website providing a photo development service and requesting development of the image.
Abstract:
A method and apparatus for recording data on and/or reproducing data from a storage medium are provided. The recording apparatus includes an authenticating unit which authenticates a host, which transmits a write command to the apparatus, to verify whether the host is authentic; at least one job module which generates output information by processing the user data, which is included in the write command, based on disc information stored in the storage medium and device information stored in the apparatus, in response to the write command; a module selecting unit which selects the job module based on module selection information and sends the write command to the selected job module, when the host is determined to be authentic, the module selection information being contained in the write command and specifying the job module; and a recording unit which records the output information on the storage medium.
Abstract:
A method and apparatus for processing an image are provided. The method includes obtaining an image, generating 3-dimensional (3D) disparity information that represents a degree of stereoscopic effects of the image, and outputting the 3D disparity information.

Abstract:
Provided is a method of copying data stored in a first storage medium to a second storage medium. The method includes recording the encrypted data stored in the first storage medium on the second storage medium; reproducing a first content key, which is used to encrypt the encrypted data, using a first drive into which the first storage medium is loaded; encrypting the first content key; sending the encrypted first content key to a second drive into which the second storage medium is loaded; and recording the encrypted first content key on the second storage medium. In this method, encrypted data stored in a first storage medium is sent to a second storage medium via a host without decrypting the encrypted data, thereby preventing the data from being hacked or being accessed by unauthorized users and increasing a speed of copying the encrypted data.
