Description

  The present invention relates to an image processing apparatus such as an MFP (Multi Function Printer).

  Since an image processing apparatus typified by a copier has been turned on for a long time, there is a great need for reducing power consumption. In particular, since there are many printers and fax functions that are compatible with the network these days, there is a high need for reducing power consumption without turning off the power at night.

  For this reason, conventionally, when the image processing apparatus enters an unused standby state, it automatically shifts to the energy saving mode (power save mode) to reduce power consumption. In addition, a technique has been proposed in which after switching to the energy saving mode, a unit necessary for processing is determined and power is restored in units (see, for example, Patent Document 1).

A conventional MFP includes an application layer such as a copy application, a FAX application, and a scanner application, and a service layer that provides a function to each application in the application layer. Processing is performed by calling a service layer function when the application is executed. Was running. Therefore, the energy saving pattern is fixed depending on the application, and energy saving control is performed according to the pattern.

<Operation: Power control during activity execution>
FIG. 11 is a flowchart showing a processing example of power control, in which the power of the unit used in the filter is turned on at the start of the filter processing, and the power of the unit used in the filter is turned off at the end of the processing. In addition, when the power control for energy saving is performed on the activity side (Fig. 4), the power control for energy saving is performed on the filter side (Fig. 6), This is a processing example common to power control (not shown).

  In FIG. 11, when the activity starts execution (step S201), the processing of the filter to be executed (the top filter when executing from the beginning of the activity, the top filter in the standby state when executing from the middle) is started. (Step S202).

  Next, based on the power management table PT (FIGS. 5 and 7), the power supply of the unit used in the filter is turned on (step S203), and then the original processing of the filter is executed (step S204).

  When the filter process is completed, the power supply of the unit used in the filter is turned off (step S205). Note that the power supply is not turned off for the units used in other activity filters.

  Next, it is determined whether or not all the filters have been processed (step S206). If not, the same process is repeated from the start of the next execution target filter process (step S202).

  If all the filters have been processed, the power supply control process is terminated (step S207).

Filter F1 is “read” and filter F2 is “process”. The filter F3 is “printing”, the filter F4 is “reading”, the filter F5 is “processing”, and the filter F6 is “transmission”.

  In FIG. 13, when the “read” filter F1 of the activity A1 is completed, the filter F1 does not require the “scanner” unit # 1, but the “read” filter F4 of the activity A2 uses the “scanner” unit # 1. Therefore, the power of the “scanner” unit # 1 is turned off after the execution of the “read” filter F4 is completed. Similarly, the execution of the filters F1 to F3 of the activity A1 makes the “HDD” unit # 2 unnecessary for the filters F1 to F3, but the “transmission” filter F6 of the activity A2 uses the “HDD” unit # 2. Therefore, the “HDD” unit # 2 is powered off after the execution of the “transmission” filter F6 is completed.

  FIG. 14 is a flowchart showing another processing example of power control, in which the unit used in the filter included in the activity is turned on at the start of the activity processing, and the unit used in the filter at the end of the filter processing. Thus, the power of the unit not used by other filters is turned off.

  When the filter processing is completed, the power of the units that can be turned off among the units used in the filter is turned off (step S215). FIG. 15 is a diagram showing an example of a method for discriminating a unit that can be turned off. The total value used in each filter for each unit is managed by a semaphore counter. When the semaphore counter is “1”, the power is turned off. Make it possible. Note that the units used in other activity filters may be considered together.

  Returning to FIG. 14, it is determined whether or not all the filters have been processed (step S <b> 216). If not, the same process is repeated from the start of the next execution target filter process (step S <b> 213).

  When all the filters have been processed, the power supply control process is terminated (step S217).

  FIG. 16 is a diagram showing an example of the relationship between execution of activity / filter and power ON / OFF of each unit. When filter F1 is “read”, filter F2 is “process”, and filter F3 is “print”, At the start of execution of activity A1, all units # 1 to # 3 used in filters F1 to F3 of activity A1 are turned on, and “scanner” unit # 1 used only in “read” filter F1 When the execution is completed, the power is turned off, and the “HDD” unit # 2 used in all the filters F1 to F3 is turned off by the completion of the execution of the filter F3 and is used only by the “print” filter F3. Unit # 3 is powered off upon completion of execution of filter F3.

When an activity process starts, the unit used in the activity is turned on, and when the activity process ends, the unit used in the activity is turned off. Is. In addition, when the power control for energy saving is performed on the activity side (Fig. 4), the power control for energy saving is performed on the filter side (Fig. 6), This is a processing example common to power control (not shown).

  In FIG. 17, when the activity starts execution (step S221), the power source of the unit used in the activity is turned on based on the power management table PT (FIGS. 5 and 7) (step S222).

  Next, the processing of the filter to be executed (the first filter when executing from the beginning of the activity, the first filter in the standby state when executing from the middle) is started (step S223), and the original processing of the filter is executed (step S223). Step S224).

  When the filter process is completed, it is determined whether all the filter processes have been completed (step S225). If the filter process has not been completed, the same process is repeated from the start of the next execution target filter process (step S223).

  When all the filters have been processed, the power of the unit used in the activity is turned off (step S226), and the power control process is ended (step S227). It should be noted that a unit used in a filter for other activities may be taken into consideration when the unit is turned off.
