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.

Provided are an imaging method for use with a variable coded aperture filter and an imaging apparatus using the imaging method. The variable coded aperture filter includes a plurality of regulated patterns which may be properly selected, and an image obtained via a certain pattern of the variable coded aperture filter may be processed by a deconvolution method related to the certain pattern. The patterns in the variable coded aperture filter have different aperture degrees from each other so as to adjust an exposure amount, and accordingly, a subject which is extremely bright or extremely dark may be photographed and depth information and focus information may be obtained from the photographed image. Therefore, images of high image quality may be obtained in a large range of brightness variation.

A method and apparatus for restricting the use of a disc are provided. In this method, first, lead-in data is read out from a loaded disc. Then, a user key is read out from a lead-in area of the disc. Thereafter, the user key undergoes authentication based on a user key received from a host. The authentication is performed by comparing a random number produced by a disc drive with a decrypted random number obtained by the disc drive decrypting a random number encrypted by the host. Accordingly, the use of the disc by an unauthorized third person is restricted, thus preventing a leakage of personal information and a protection of the copyrights of data.
摘要:
A data recording medium, a recording apparatus thereof, and an apparatus for providing contents having a function of securing personal anonymity similar to a prepaid card. The prepaid card type data recording medium includes a control information area on which is recorded coupon ID information for identifying the data recording medium and representing the authority for recording contents. In addition, marginal capacity information for indicating the maximum downloadable capacity of contents may further be recorded on the control information area. The apparatus for providing contents includes an authentication unit for authenticating personal identification information, and a contents upload unit for uploading predetermined contents to the data recording medium when the authentication is successful in the authentication unit. In addition, the apparatus for providing contents further includes an information DB unit which stores marginal capacity information indicating the marginal capacity of contents to be downloaded to the data recording medium according to the coupon ID information. The authentication unit determines whether to upload the predetermined contents by referring to the information DB. Blueray disc, the next generation DVD, can be used in a mobile phone or PDA as a prepaid card type data recording medium.

A method and apparatus for image processing are provided. The method may include generating a first restoration image by removing distortion components from an original image; determining a mixing ratio between the original image and the first restoration image based on distortion information of a region of interest in the original image; and generating a second restoration image by mixing the original image and the first restoration image according to the mixing ratio.
摘要:
An image processing method and an image processing apparatus, the method including: generating a blurry image by using a maximum telephoto image among N (where N is a natural number equal to or greater than 2) live view images; generating an alpha map by using two or more images of the N live view images; and generating a soft focus image by combining the maximum telephoto image and the blurry image by using the alpha map.
