Non-transitory computer-readable recording medium having a software update program recorded thereon that selects a software update method that requires a shorter time, and software update apparatus

摘要

A software update program recorded on a non-transitory computer-readable recording medium causes a computer to act as an update instruction unit that instructs an electronic apparatus to update software, and a method selection unit that selects a method that requires a shorter time, from normal updating in which the electronic apparatus receives renewed software and updates current software to the renewed software, and incremental updating in which the electronic apparatus receives difference data between the renewed software and the current software and applies the difference data to the current software for updating to the renewed software. The update instruction unit instructs the electronic apparatus to update the software by the normal update method when the method selection unit selects the normal update method, and instructs the electronic apparatus to update the software by the incremental update method when the method selection unit selects the incremental update method.
