Classification: CPC G | IPC G

Claim 3:
4. A computer-implemented information processing method for an information processing apparatus to start an application program, the information processing method being performed by a processor, the information processing method comprising:
reading a snapshot file corresponding to the application program from a writable non-volatile storage medium and loading the read snapshot file into a RAM;
loading an operating system on which the application program operates, into the RAM, and starting the operating system without using the snapshot file;
reading, after starting the operating system, the application program from the non-volatile storage medium and loading the read application program into the RAM; and
starting the 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 operating system on which the application program operates into the RAM, or (ii) while performing a process of starting the operating system;
the information processing apparatus is configured to display an image on a display device mounted on a vehicle;
the operating system is a general-purpose operating system, the application program is a multimedia application program that operates on the general-purpose operating system, and the snapshot file corresponds to the multimedia application program;
the writable non-volatile storage medium is configured to store a real-time operating system executed by the processor, the general-purpose operating system executed by the processor, a driving-related display application program that operates on the real-time operating system to display the image related to driving 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;
the read program is included in the real-time operating system; and
the method further comprises executing, with the processor, 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.
