A compression necessity determiner (131) is configured to determine a necessity of compression of to-be-uploaded data to a server. A data compressor (132) is configured to compress, when the compression necessity determiner (131) determines that the compression of the to-be-uploaded data is necessary, the to-be-uploaded data in a predetermined scheme. When the compression necessity determiner (131) determines that the compression of the to-be-uploaded data is unnecessary, a data sender (133) sends data, in which a header is added to the to-be-uploaded data to the communication interface, and when the compression necessity determiner (131) determines that the compression of the to-be-uploaded data is necessary, the data sender (133) sends to the communication interface data in which a header, containing information indicating that the to-be-uploaded data is compressed data, is added to the to-be-uploaded data compressed by the data compressor (132). |
