Claim 2:
3. An information processing apparatus for displaying an image on a display device mounted on a vehicle, the information processing apparatus comprising:
a processor;
a RAM;
a writable non-volatile storage medium configured to store a multimedia application program, a snapshot file corresponding to the multimedia application program, and a driving-related display application program configured to display an image related to driving of the vehicle on the display device;
a bus connecting the processor, the RAM, and the non-volatile storage medium with each other;
a second operating system configured to cause the processor to (i) load the multimedia application program from the non-volatile storage medium into the RAM and (ii) start the multimedia application program;
a read program configured to cause the processor to read the snapshot file from the non-volatile storage medium and load the read snapshot file into the RAM, (i) before the second operating system is loaded into the RAM or (ii) while a process of starting the second operating system is being performed; and
a first operating system being a real-time operating system configured to cause the processor to (i) load the driving-related display application program from the non-volatile storage medium into the RAM and (ii) start the driving-related display application program,
wherein:
loading the second operating system into the RAM is started after a process of starting the first operating system is completed;
the information processing apparatus is configured to display the image on the display device mounted on the vehicle;
the second operating system is a general-purpose operating system, the multimedia application program operates on the general-purpose operating system, and the snapshot file corresponds to the multimedia application program;
the driving-related display application program operates on the real-time operating system to display the image related to driving of the vehicle on the display device;
loading the general-purpose operating system into the RAM is started after a process of starting the real-time operating system is completed;
the read program is included in the real-time operating system; and
the processor is configured to execute the real-time operating system to read the snapshot file from the non-volatile storage medium and load the snapshot file into the RAM, after completing a process of starting the driving-related display application program and before starting loading the general-purpose operating system into the RAM.
