Image processing apparatus and method of controlling image processing apparatus

An image processing apparatus comprising:

• a human sensor that detects a human body;
• an operation unit for performing various settings;
• and
• a control unit capable of switching an operation mode between a normal mode in which image processing is performed and a sleep mode in which consumption power is saved,
• the image processing apparatus further comprising:
• a first count timer that, in a case where no inputting from the operation unit occurs in a first set time set in the first count timer, switches from the normal mode to the sleep mode;
• wherein in a case where a human body is detected by the human sensor, the control unit switches from the sleep mode to the normal mode,
• and wherein in the normal mode, in a case where the human sensor no longer detects a human body or the human sensor detects a human body leaving, the control unit clears a setting of the operation unit and starts counting down a second set time set in a second count timer for switching from the normal mode to the sleep mode.
