<p>PROBLEM TO BE SOLVED: To provide a technique for announcing a free capacity even when FTP is used.SOLUTION: A recording unit 42 records moving image data. A detection unit 44 detects variation in a free capacity of the recording unit 42. A measurement unit 46 measures the free capacity, when the detection unit 44 detects the variation. A file generation unit 48 generates a file showing the free capacity measured by the measurement unit 46 and causes the recording unit 42 to record the generated file. A communication unit 40 transmits, by FTP, the file recorded by the recording unit 42 in response to the instruction of the file generation unit 48.</p> |
