A user terminal includes: an acquisition unit configured to acquire processing target data that includes image data; a measurement unit configured to measure, as biological information, line-of-sight information on a user on the user and other biological information other than the line-of-sight information; a calculation unit configured to calculates importance of the processing target data based on the line-of-sight information and the other biological information; a determination unit configured to determine a compression detail of the processing target data in accordance with the calculated importance; and a compression unit configured to compress the processing target data in accordance with the compression detail that is determined by the determination unit.

User terminal, data processing method, and non-transitory storage medium

A storage apparatus includes a biological sensor configured to detect biological information on a user, an image acquisition unit configured to acquire, from an image capturing unit, an image that is captured around the user, an image processing unit configured to separate the image around the user into a line-of-sight direction image related to an image in a line-of-sight direction of the user and a peripheral image related to an image other than the line-of-sight direction image, an encryption unit configured to generate an encryption key for encrypting the line-of-sight direction image based on the biological information on the user, and encrypts the line-of-sight direction image by using the encryption key, and a storage control unit configured to store the line-of-sight direction image that is encrypted by the encryption unit in a storage unit.

Storage apparatus, storage method, and computer-readable storage medium

A display device includes a display in which an image is displayed; an output controller configured to display an image in the display; an imager configured to capture an image of an object present within a field of view of a user; a visually recognized object identifying unit configured to identify, based on the captured image, a type of the object present within the field of view of the user; and a visual recognition count identifying unit configured to, based on an identification result by the visually recognized object identifying unit, identify a visual recognition count indicating a number of times by which the user has looked at the object for each of the identified type, wherein the output controller is further configured to display in the display, based on the visual recognition count, a sub image including information on the object for each of the identified type.

Display device, display method, and non-transitory storage medium

An image coding device adapted to code time-continuous pictures is provided. An embedding position information conversion unit acquires embedding position information indicating a position in a picture, by using a one-way function based on time-continuous information. An image coding unit selects a coding block in the picture based on the embedding position information, embeds electronic watermark information in a coding parameter used to code the coding block, and codes the coding block by using the coding parameter in which the electronic watermark information is embedded.

Image coding device, image coding method, and image falsification identification program

A projector includes, a projecting unit that converts image data into light and projects the light at a predetermined angle of view, a projecting direction changing unit that changes the projecting direction of the projecting unit from a first projecting direction to a second projecting direction, a projection angle derivation unit that derives a projection angle between the first projecting direction and a projecting direction after changed, and an image cutting out unit that generates cut-out image data that a part of a region of an image of the inputted image data is cut out based on the angle of view and the projection angle as image data to be projected, when the projecting unit projects the image of the inputted image data stored on the storage unit across the first projecting direction and the second projecting direction.

In a reproduction apparatus, for reproducing an original signal conveyed as main data by a data medium such as a recording disk or broadcasting system, with medium protection data which are specific to the data medium being conveyed together with the main data, the apparatus includes a section for generating apparatus protection data which are specific to the reproduction apparatus, a section for combining the apparatus protection data with the medium protection data to define a protection level, and a section for applying the protection level to restrict reproduction of the original signal, with stepwise variations in restriction occurring in accordance with changes in protection level. The medium protection data may include information for specifying restricted reproduction of portions of the original signal, such as by producing degraded resolution within specified regions of specified frames of a video signal.

Method for protection of data reproduction according to both medium protection data and apparatus protection data

Executes a re-encoding after decoding data of a connection section A of a first MPEG picture data. This re-encoding is executed based on a control such that a transition of a VBV buffer occupation value starts from a VBV buffer occupation value at a position a and ends with a VBV buffer occupation value at a position d. Up to the position a of the first MPEG picture data, the first MPEG picture data is reproduced. Next, re-encoded MPEG picture data of the connection section A is reproduced. Thereafter, the data is connected to the position d of a second MPEG picture data, and the second MPEG picture data of the position d and after is reproduced.

A compressively-encoding-resultant video signal resulting from compressively encoding a video signal, a first compressively-encoding-resultant audio signal resulting from compressively encoding a first audio signal having a synchronized relation with the video signal, a reference clock information signal relating to synchronization between the compressively-encoding-resultant video signal and the first compressively-encoding-resultant audio signal, and an indication timing information signal designating an indication timing of the video signal are multiplexed to get an AV multiplexing-resultant signal. A second audio signal is compressively encoded to get a second compressively-encoding-resultant audio signal. A sound-production-timing information signal is added to the second compressively-encoding-resultant audio signal to get a substitution playback audio signal. During playback, the substitution playback audio signal can be reproduced instead of the first audio signal while being synchronous with the video signal. The sound-production-timing information signal responds to the reference clock information signal, and relates to synchronization with the video signal.

Method and apparatus for generating information signal to be recorded

An audio signal is compressively encoded into encoding-resultant audio data. A video signal is compressively encoded into encoding-resultant video data. An audio time stamp for audio-vide synchronous reproduction is added to every unit of the encoding-resultant audio data. A video time stamp for audio-video synchronous reproduction is added to every unit of the encoding-resultant video data. The time-stamp-added audio data and the time-stamp-added video data are multiplexed into main data. To a plurality of first after-recording-purpose data for at least one of (1) the encoding-resultant audio data and (2) the encoding-resultant video data which form the main data, time stamps for reproduction synchronous with a portion of the main data and identification information for identifying the plurality of first after-recording-purpose data are added to convert the first after-recording-purpose data into second after-recording-purpose data. The second after-recording-purpose data are made into bit streams without being multiplexed with the main data.
