A digital camera capable of compensating a portion of a captured image with another image without putting a squeeze on storage capacity. The digital camera has a plurality of image-capturing systems capable of essentially simultaneously capturing images of a single subject at mutually-different angles of view. Information about relevant image data which are items of the other simultaneously-captured image data is imparted as relevant information to at least one item of image data among items of image data captured by the plurality of image-capturing systems. The image data imparted with the relevant information and the relevant image data captured simultaneously with the image data are stored as separate items of data in user memory which serves as storage means.

There is disclosed an image synthesizing apparatus for producing a synthetic image that consists of a background image and at least a main image superimposed on the back ground image. An input image is displayed in a main display area of a control screen, whereas an outer frame and at least an inner frame are displayed in a sub display area of the control screen in accordance with a selected template.

Then, a crop boundary having a similar shape to the inner frame is displayed on the second image, so a cropped area of the second image is pasted in the inner frame, to be printed as the main image.

A signature system in which size of data to be transmitted is small and data can be processed efficiently in a Merkle signature system having high security. A processing part 112 of a smartcard 110 divides a message to be signed into groups of specific numbers of bits, starting from the first bit of the message. Then, respective partial one-time signatures of the groups are generated by encrypting each group by a one-way function processing part 112c. The partial one-time signatures are sequentially outputted to a verification apparatus through a interface part 113.

A system for monitoring actions performed on a data processing device by one or more users. The system comprises a plurality of user data processing devices including a mechanism for interacting with a user and a system monitor that can communicate with each user device and a database. In an exemplary embodiment, the monitor includes a plurality of software agents for carrying out specific functionality. These agents may be distributed over one or many different machines.

A cache memory controller in a computer system, such as a multicore processing system, provides compression for writes to memory, such as an off-chip memory, and decompression after reads from memory. Application accelerator processors in the system generate application data and requests to read/write the data from/to memory. The cache memory controller uses information relating location parameters of buffers allocated for application data and sets parameters to configure compression and decompression operations. The cache memory controller monitors memory addresses specified in read requests and write requests from/to the first memory. The requested memory address is compared to the location parameters for the allocated buffers to select the set of parameters for the particular application data. Compression or decompression is applied to the application data in accordance with the selected set of parameters. The data size of the data transferred to/from memory is reduced.

A need exists for a technology for guaranteeing the authenticity of an electronic document, and an information disclosure system, which can guarantee the authenticity of a disclosed document and delete information regarded as inappropriate for disclosure. An electronic document is divided into components, and a random number generated from a seed value is concatenated to each of the components. A hash value is calculated for each of the components with which the random numbers have been concatenated. The calculated hash values are further concatenated using a hash function to generate data to which an digital signature is applied.

A client-server arrangement for camera viewing using digital cameras across a computer network. A camera server controls a motorized gimbal which determines the viewing angles of a set of cameras according to signals from a client computer which is equipped with an eye movement tracking system. Movements of the viewer's eyes result in changes in viewing angle of the remote cameras. A high resolution foveal field of view image centered on the user's point of interest is captured and overlaid on a lower resolution full filed of view image, rendering a combined image having a low resolution peripheral area and a high resolution foveal area, and being significantly reduced in size compared to a full resolution, full field of view image. This combined image is transmitted to the client for display to the user.

A central device uses a link shape compression unit to compress information of shape of ups and downs of a road link obtained from a three-dimensional road map, and calculates a geometry parameter based on variation of energy of a vehicle travelling on the road link. An on-board terminal device estimates the vehicle's average travelling pattern by using a travel-pattern-estimation unit based on the geometry parameter calculated by the central device, a link-travelling time estimated from statistically-stored traffic information, and a link length. The on-board terminal device further calculates fuel consumption of the vehicle travelling on each road link based on the estimated travelling pattern and parameters of the vehicle by using a fuel-consumption calculation unit, and then, searches a fuel-efficient route by using the fuel consumption as a link cost. The on-board terminal device has a vehicle-type selector for selecting a type of the vehicle. The present invention can reduce data size of information processed by the on-board terminal device, and facilitate application of a fuel-efficient route search to various types of vehicles.

In an image encoding process for encoding data of an inputted image and outputting encoded image data: an image-size condition including image size and target sharpness is stored in an image-size-condition storage; a reduced image of the inputted image having the above image size included in the image-size condition stored in the image-size-condition storage is produced; and the sharpness of the reduced image is calculated. When the calculated sharpness of the reduced image is higher than the target sharpness, the image size included in the image-size condition stored in the image-size-condition storage is reduced, and a further reduced image of the inputted image having the reduced image size is produced.

A server generates area-specific particular information beforehand, and obtains positional information and route information from a vehicle-mounted navigation apparatus or a vehicle. The server determines particular information to be sent to the vehicle-mounted navigation apparatus or whether a warning is necessary, for each area segment including location indicated by the positional information and/or the route information. The server then distributes necessary particular information or area-specific threshold data. The vehicle-mounted navigation apparatus receives the information from the server, determines whether or not a warning is necessary in the area segment of the present position of the vehicle using the area-specific threshold data, and displays the particular information or the warning.
