Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<First embodiment>
First, a first embodiment will be described.

[Overview and prerequisites]
First, the outline and preconditions of the image forming apparatus according to the first embodiment of the present invention will be described. In the image forming apparatus according to the first embodiment of the present invention, it is assumed that each module constituting the image forming apparatus is sequentially initialized one by one when the power is turned on or when returning from the energy saving mode.

  In a typical technique, after all the modules are initialized, a ready screen indicating that the module is ready to be used is displayed, and the module becomes ready for use.

  For example, if there are modules A to D, the initialization order is not available until four modules are initialized.

  On the other hand, in the image forming apparatus according to the first embodiment of the present invention, the image forming apparatus is ready for use at the time when only the module related to the function required by the user is immediately initialized. The image forming apparatus can be used quickly.

  For example, it is assumed that modules B and C are used when the function that the user wants to use immediately is a send function for transmitting electronic data obtained by scanning a document to a PC (Personal Computer).

  In that case, assuming that the normal module initialization order is the order of modules A, B, C, and D, the image forming apparatus skips the initialization of module A and completes the initialization of modules B and C. At this point, the ready screen is displayed and the device becomes ready for use.

  In the case of the above example, initialization of the modules A and D irrelevant to the send function is performed later.

  Note that the image forming apparatus according to the first embodiment of the present invention refers to the initial screen in order to determine what function the user wants to use immediately.

  For example, when the user sets the initial screen as the operation screen for the send function, the user interprets that the send screen is set as the initial screen since the user often uses the send function.

  If the initial screen is set to a screen for operating the copy function, the function that the user wants to use is interpreted as the copy function.

  If the user performs an operation for using another function while performing initialization of the module according to the above-described interpretation, the image forming apparatus suspends the initialization currently being performed and newly performs the operation. Initialize the modules that the user will use.

  The outline and the preconditions of the image forming apparatus according to the first embodiment of the present invention have been described above.

Further, when the scanner and the print engine, which are modules for realizing the copy function set on the initial screen, are sequentially initialized, the operation detection unit detects an operation by the user regarding the send function. In this case, the initialization suspension instruction unit issues an instruction to suspend the initialization of the print engine, which is a module unrelated to the send function . The initial screen setting unit is used to operate at least the functions provided by the image forming apparatus, including the copy function and the send function, which are displayed on the display unit when the image forming apparatus starts up or returns from the energy saving mode. The initial screen of is set by a user's instruction via the operation unit, and information on the setting is stored in the storage unit as initial screen information.
An initial screen confirmation unit confirms the initial screen information stored in the storage unit at the time of startup of the own device or when returning from the energy saving mode,
An initialization instruction unit issues an initialization instruction to all of a plurality of modules for realizing a plurality of functions provided by the own device,
When all of the plurality of modules are initialized at the same time in parallel, a function set on the initial screen among the plurality of modules based on the initial screen information confirmed by the initial screen confirmation unit. Interrupt the initialization of modules other than the module related to
When the initialization of only the module related to the function is completed, a ready screen indicating that the image forming apparatus is ready for use is displayed,
After displaying the ready screen, and out of the resume instruction to initialize the module to interrupt the initialization,
The operation detection unit, when only the module related to the function set on the initial screen is initialized, detects an operation by the user regarding a function different from the function set on the initial screen,
An initialization interruption instruction unit, when the operation is detected by the operation detection unit, issues an instruction to interrupt initialization of a module not related to the different function,
Further, when only the scanner and the print engine, which are modules for realizing the copy function set on the initial screen, are initialized, the operation detection unit detects an operation by the user regarding the send function. In this case, the initialization suspension instruction unit issues an instruction to suspend the initialization of the print engine, which is a module unrelated to the send function .
