Abstract:
1. An image processing apparatus for inputting commands via a Universal Serial Bus (USB) host interface, a USB device interface, and a network interface, and for performing various processes for input image data, comprising: first input means for inputting, via the network interface of said image processing apparatus, a first file access command which requests access to a storage medium connected to the USB host interface; second input means for inputting a second file access command generated inside said image processing apparatus; file access control means for performing exclusive access control between the first file access command input by said first input means, and the second file access command input by said second input means; command conversion means, which is provided between the file access control means and the USB host interface to acquire any one of the file access commands from the file access control means, for converting either the first file access command or the second file access command selected by the exclusive access control by said file access control means into a Small Computer System Interface (SCSI) command; and storage medium access control means for performing exclusive access control between the SCSI command generated by a conversion by said command conversion means, and a SCSI command which is input via the USB device interface of said image processing apparatus without using said file access control means and for requesting access to the storage medium.
