Image processing apparatus and control method for image processing apparatus

A control method for an image processing apparatus that includes a first controller configured to control the whole image processing apparatus and not to be energized in a power saving mode of the image processing apparatus, and a second controller configured to be energized in the power saving mode, the control method comprising:

• generating a return trigger for returning from the power saving mode to a normal mode of the image processing apparatus;
• by the second controller,
• detecting the return trigger;
• identifying the detected return trigger;
• storing the identified return trigger into a storage medium;
• starting energizing the first controller in accordance with the detection of the return trigger;
• by the first controller,
• reading the stored return trigger after the first controller is energized;
• determining a function to be activated preferentially on the basis of the read return trigger;
• and
• activating the determined function preferentially,
• wherein the determining of a function to be activated preferentially includes determining of the function to be preferentially activated on the basis of the read return trigger and activates only the determined function.

An image processing apparatus, comprising:

• first processing circuitry to control the whole image processing apparatus and not to be energized in a power saving mode of the image processing apparatus;
• and
• second processing circuitry to be energized in the power saving mode, wherein
• the second processing circuitry is configured to:
• detect a return trigger for returning from the power saving mode to a normal mode of the image processing apparatus,
• identify the detected return trigger,
• store the identified return trigger into a storage medium, and
• start energizing the first processing circuitry in accordance with the detection of the return trigger, and
• the first processing circuitry is configured to
• read the stored return trigger after the first control unit is energized, and
• determine a function to be activated preferentially on the basis of the read return trigger and activate the determined function preferentially,
• wherein the determining of the function to be activated preferentially includes determining a function to be preferentially activated on the basis of the read return trigger and activates only the determined function.
