Abstract: The present invention is an image processing apparatus for converting an original image into an enlarged image on which enlargement processing has been performed with respect to a reference point, as the center, including: a selection processing unit that treats, as a starting point, a coordinate point which is the farthest from the reference point and selects a processing-target pixel from among pixels constituting the enlarged image; a calculation processing unit that calculates a coordinate point of the original image which is mapped to the coordinate point of the processing-target pixel; a reading processing unit that reads the pixel value of a pixel of the original image from the recording medium in accordance with the coordinate point of the original image; an interpolation processing unit that interpolates the pixel value of the processing-target pixel using the pixel value of the pixel of the original image read by the reading processing unit; and a writing processing unit that writes the pixel value

Abstract: The present invention is an image processing apparatus for changing the resolution of image data in accordance with the distance from a reference point arbitrarily set within a screen showing the image data, including: selection means for selecting, from the image data, calculation-target pixels that are arranged in such a manner that the spacing between pixels becomes larger as the distance from the reference point increases; smoothing processing means for smoothing the calculation-target pixels selected by the selection means using the pixel values of the calculation-target pixels and the pixel values of pixels positioned around the calculation-target pixels; and interpolation processing means for interpolating the pixel values of pixels which have not been selected as the calculation-target pixels by the selection means, from the pixel values of calculation-target pixels positioned around the pixels, the calculation-target pixels having been smoothed by the smoothing processing means.

Abstract: Input data (plain text data or encrypted text data) are latched according to a clock CLK1 and, after initial transposition thereof, the data are outputted from a selector. The lower-order bits of the output data from the selector are processed through expanded transposition and then are calculated together with key data K1 in an XOR circuit, and the result data are latched according to a clock CLK2. The latched 48-bit data are divided into eight 6-bits data, each of which is then replaced with 4-bit data, and after combination thereof, the data are transposed. In the calculations of second and subsequent stages, the data obtained through replacement and combination in a replacement/combination circuit are latched according to the clock CLK1 and then are outputted from the selector. And after completion of the 16th-stage calculation, the data replaced in a replacement circuit are inversely transposed.

Abstract: A data transfer apparatus referred to as a primary-recording-medium apparatus implements proper system operations by acquisition of information on a secondary recording medium mounted on a secondary-recording-medium apparatus to serve as a destination of a transfer (or a check-out) of a content. If a medium adopting its own unique management technique as is the case with a mini disc is used as the secondary recording medium serving as a destination of a check-out, the primary-recording-medium apparatus acquires information on the secondary recording medium from the secondary-recording-medium apparatus, which is typically a data-recording apparatus.

Abstract: A data transfer system provided by the present invention is capable of executing proper management of content transfers with a high degree of efficiency. In a data transfer apparatus employing a primary recording medium, rights to transfer contents stored in a primary recording medium are managed, and transfer rights of contents already transferred to a secondary recording medium employed in a data-recording apparatus are managed by using a generated table for associating first content identifiers each generated by the data transfer apparatus for a content stored in the primary recording medium with a second content identifier received from the data-recording apparatus and generated by the data-recording apparatus for the content, which has already been transferred to the data-recording apparatus.

Abstract: The present invention is intended to significantly reduce the content data processing and transfer times by skipping root key checking processing, when transmitting a plurality of pieces of encrypted content data stored in a primary recording medium to a secondary recording medium along with key information of these plural pieces of content data, if the key information for a piece of content data to be transmitted from the primary recording medium is the same as the key information for an already transmitted piece of content data.

Abstract: Disclosed is a method for causing either encrypted first content data or unencrypted second content data, to be selectively recorded to a storage medium in a data recording apparatus. When the data recording apparatus is to return the encrypted first content data to the data transfer apparatus, the return is inhibited if the data are judged to have been edited. Upon return of the encrypted first content data, a content ID held by the data recording apparatus regarding the first content data is matched against a content ID held by the data transfer apparatus regarding the received data. Where the encrypted first content data are known to have been edited, the content ID matching process is omitted.

Abstract: A data transfer apparatus for simplifying a module structure for controlling a connected data recording apparatus and improving the processing efficiency. A control code issued by a common application module having a main purpose of check-out/check-in is made a control code corresponding to a device connected by a conversion module and transmitted via a device driver. Moreover, for example, a control code issued by a local application module having a main purpose of controlling processing depending on a device connected shares the aforementioned device driver. For example, the local application module issues a control code in a state matched with a control code format converted by the conversion module. Alternatively, the local application module issues a local control code by indicating issuance of a local control code of a format different from the control code format converted by the conversion module.

Abstract: Input data (plain text data or encrypted text data) are latched according to a clock CLK1 and, after initial transposition thereof, the data are outputted from a selector 62. The lower-order bits of the output data from the selector 62 are processed through expanded transposition and then are calculated together with key data K1 in an XOR circuit, and the result data are latched according to a clock CLK2. The latched 48-bit data are divided into eight 6-bits data, each of which is then replaced with 4-bit data, and after combination thereof, the data are transposed. In the calculations of second and subsequent stages, the data obtained through replacement and combination in a replacement/combination circuit 66 are latched according to the clock CLK1 and then are outputted from the selector 62.

Abstract: Disclosed is a method for causing either first content data transferred encrypted from a data transfer apparatus or second content data which are input unencrypted to be selectively recorded to a storage medium in a data recording apparatus. Given a command for editing the content data recorded on the storage medium, editing of the recorded data is inhibited or restricted if the data are judged to be the encrypted first content data. When the data recording apparatus is to return the encrypted first content data from the storage medium to the data transfer apparatus, the return of the first content data is inhibited if the data are judged to have been edited. Upon return of the encrypted first content data to the data transfer apparatus, a content ID held by the data recording apparatus regarding the first content data is matched against a content ID held by the data transfer apparatus regarding the same data.

Abstract: Picture signals entering a picture input device 4 are compressed by a picture compression device 5 for storing the resulting compressed picture data in a secondary storage device 7 via a primary storage device 6. The picture compression system is switched for recording a moving picture and for recording a still picture by switching picture compression parameters of the picture compression device 5 by a picture compression system switching device 10 between those for moving picture recording and those for still picture recording.
