Abstract

An information processing apparatus, an information processing system, an information processing method and a program, which can store display data efficiently, are provided.

A detecting section which detects a carrier wave near the receiving section, a switching control section which controls a switching section so as to, when the detecting section detects the carrier wave, switch connecting destination of the first storage section into the receiving section, and when the detecting section does not detect the carrier wave, switch the connecting destination of the first storage section into the reading section, a second storage section which stores the data conversion information read by the reading section, and a display control section which converts the read display data using the data conversion information stored in the second storage section so as to display the information on the display section are provided.

Claims

1. An information processing apparatus comprising:

a receiving section which receives a magnetic field signal;

a first storage section which stores display data contained in the magnetic field signal and data conversion information for converting the display data into information displayable on a display section therein;

a reading section which reads the display data and the data conversion information stored in the first storage section;

a detecting section which detects a carrier wave near the receiving section;

a switching control section which controls a switching section so as to, when the detecting section detects the carrier wave, switch connecting destination of the first storage section into the receiving section, and when the detecting section does not detect the carrier wave, switch the connecting destination of the first storage section into the reading section;

a second storage section which stores the data conversion information read by the reading section; and

a display control section which converts the read display data using the data conversion information stored in the second storage section, so as to display the information on the display section.

2. The information processing apparatus according to claim 1, wherein

when the data conversion information contained in the magnetic field signal received by the receiving section is updated based on the data conversion information stored in the second storage section,

the reading section reads the data conversion information stored in the first storage section, and

the second storage section updates the data conversion information already stored into the updated data conversion information.

3. An information processing system comprising:

a first device which receives data via wireless communication and stores the data therein; and

a second device which transmits/receives the data to/from the first device;

wherein the first device includes;

a receiving section which receives a magnetic field signal;

a first storage section which stores display data contained in the magnetic field signal and data conversion information for converting the display data into information displayable on a display section therein;

a reading section which reads the display data and the data conversion information stored in the first storage section;

a detecting section which detects a carrier wave near the receiving section;

a switching control section which controls a switching section so as to, when the detecting section detects the carrier wave, switch connecting destination of the first storage section into the receiving section, and when the detecting section does not detect the carrier wave, switch the connecting destination of the first storage section into the reading section;

a second storage section which stores the data conversion information read by the reading section therein; and

a display control section which converts the read display data using the data conversion information stored in the second storage section, so as to display the information on the display section,

the second device starts or interrupts transmission of a carrier wave at any timing.

4. An information processing method comprising the steps of:

receiving a magnetic field signal by means of a receiving section;

storing display data contained in the magnetic field signal and data conversion information for converting the display data into information displayable on a display section in a first storage section;

reading the display data and the data conversion information stored in the first storage section;

detecting a carrier wave near the receiving section;

controlling a switching section so that when the carrier wave is detected, connecting destination of the first storage section is switched into the receiving section, and when the carrier wave is not detected, the connecting destination of the first storage section is switched into the reading section;

storing the read data conversion information in a second storage section; and

converting the read display data using the data conversion information stored in the second storage section and displaying the information on a display section.

5. A program which allows a computer to function as:

a unit which receives a magnetic field signal by means of a receiving section;

a unit which stores display data contained in the magnetic field signal and data conversion information for converting the display data into information displayable on a display section in a first storage section;

a unit which reads the display data and the data conversion information stored in the first storage section;

a unit which detects a carrier wave near the receiving section;

a unit which controls a switching section so that when the carrier wave is detected, connecting destination of the first storage section is switched into the receiving section, and when the carrier wave is not detected, the connecting destination of the first storage section is switched into a reading section;

a unit which stores the read data conversion information in a second storage section; and

a unit which converts the read display data using the data conversion information stored in the second storage section and displays the information on the display section.
