Patent ID: 8031196

Claim:
A display device including a display section, and obtaining, from a device as a host, a pattern specifying code that specifies an image of a pattern and a display position of the image, so as to cause the display section to display the image in accordance with the pattern specifying code, said display device comprising: a pattern storage section which stores therein an image of a pattern with which a status of the device as the host is notified to a user, and an image of a pattern through which the user performs entry or operation; a pattern specifying code input section which externally receives the pattern specifying code in a form of electrical signal from the device; a pattern display processing section which retrieves the image of the pattern specified by the pattern specifying code from the pattern storage section and then causes the display section to display the image thereon; an automatic placement adjustment section which holds the display position specified by the pattern specifying code, and changes a display position of an image of a second pattern from the held display position in accordance with a movement of an image of a first pattern, so as to perform placement adjustment with respect to the image of the pattern; and an emulation section configured to emulate a file system of the device as the host so as to deceive the device as the host into believing that a storage device is the device as the host's storage device, the storage device storing therein a substitution code which is a program read out as a code of a subroutine called in a drawing program of the device as the host for drawing the image of the pattern and returns to the drawing program of the device as the host in a normal end state after execution of the subroutine.
