Classification: CPC G | IPC G

Claim 4:
5. A computer-implemented information processing method for an information processing apparatus to display an image on a display device mounted on a vehicle by starting (i) a travel-related display application program to display an image related to a travel of the vehicle and (ii) a multimedia application program, the information processing method being performed by a processor, the information processing method comprising:
reading a snapshot file corresponding to the multimedia application program from a writable non-volatile storage medium and loading the read snapshot file into a RAM;
loading a first operating system being a real-time operating system on which the travel-related display application program operates, into the RAM, and starting the first operating system;
loading, after completing starting the first operating system, a second operating system being a general-purpose operating system on which the multimedia application program operates, into the RAM, and staring the second operating system;
reading, after completing starting the second operating system, the multimedia application program from the non-volatile storage medium and loading the read multimedia application program into the RAM; and
starting the multimedia application program loaded in the RAM by using the snapshot file loaded in the RAM,
wherein:
reading the snapshot file from the non-volatile storage medium and loading the read snapshot file into the RAM are performed by the processor (i) before loading the second operating system on which the multimedia application program operates into the RAM, or (ii) while performing a process of starting the second operating system;
the non-volatile storage medium is configured to store the real-time operating system, the general-purpose operating system, the travel-related display application program that operates on the real-time operating system to display an image related to travel of the vehicle on the display device, and the multimedia application program that operates on the general-purpose operating system;
loading the general-purpose operating system into the RAM is started after a process of starting the real-time operating system is completed; and
the information processing method further comprising executing 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 travel-related display application program and before starting loading the general-purpose operating system into the RAM.
