Abstract: An information synchronization system includes a first information processing apparatus and second information processing apparatuses to be synchronized with setting information. The first information processing apparatus includes first circuitry to determine a delegation destination apparatus from the second information processing apparatuses, transmit the setting information, registration information, and a request for processing related to synchronization of the setting information to the delegation destination apparatus, and transmit the setting information to the second information processing apparatuses.

Abstract: An information processing apparatus that executes second software capable of communicating with first software running on an information terminal, includes a receiver unit to receive version information of the first software from the information terminal; a function identification unit configured, if a newer version of the first software is obtainable, to refer to function information in which available functions are associated with the version information of the first software and the second software, respectively, so as to obtain first functions available with the first software after a version upgrade to the newer version, and second functions available with a current version information of the second software, and to identify available functions commonly with the first functions and the second functions; and a transmitter unit to transmit the identified available functions to the information terminal.

Abstract: An information processing apparatus includes an image converter configured to extract a plurality of vertices of an object in a raster image and at least one line connecting the plurality of vertices, and to convert the raster image into vector information expressed by information of the plurality of vertices and the at least one line; and a transmitter configured to transmit the vector information.
