Information processing device, information processing method, and image processing device

An information processing method comprising:

• computing, by a computing unit, during a power saving mode that reduces power consumption, a power consumption per a predetermined time, using a count per type of an interrupt signal produced during the power saving mode, and a power consumption pre-estimated per type of the interrupt signal;
• displaying, by a display, a power consumption computed by the computing;
• keeping, by a controller, a count of a power rise factor during the power saving mode that does not require reactivation from the power saving mode:
• and
• in a case of a mode other than the power saving mode, instead of computing a power consumption using a count per type of the interrupt signal and a power consumption pre-estimated per type of the interrupt signal, computing, by the computing unit, a power consumption per a predetermined time during the power saving mode, using count per type of the interrupt signal, a power consumption pre-estimated per type of the interrupt signal, a count result of the controller, and a power consumption pre-estimated from the power rise factor.

An image processing device comprising:

• an image processor equipped with at least one processing function from among:
• an image reading processing function for reading a document image;
• an image copying processing function that copies a document image read by the image reading processing function onto a printing sheet;
• an image forming function that forms an image onto a printing sheet using received image information;
• and
• an image information transmitting function that transmits information of a document image read by the image reading processing function;
• a main controller that includes a controlling function that controls the image processor, in addition to a sensing function that senses a type and a count of an interrupt signal produced in a power saving mode that reduces power consumption, and outputs a sensing result in response to the interrupt signal;
• a display configured to display a power consumption;
• and
• at least one processor configured to operate on electric power, and using the sensing result output from the main controller and a power consumption pre-estimated per type of the interrupt signal, control, during the power saving mode, computation and display on the display of a power consumption per a predetermined time,
• wherein the main controller is configured to keep a count of a power rise factor during the power saving mode that does not require reactivation from the power saving mode, and
• wherein the at least one processor is configured to, in case of a mode other than the power saving mode, instead of computing a power consumption using the sensing result and a power consumption pre-estimated per type of the interrupt signal, control computation and display on the display of a power consumption per a predetermined time during the power saving mode, using a count per type of the interrupt signal, a power consumtion pre-estimated per type of the interrupt signal, a count result of the main controller, and a power consumption pre-estimated from the power rise factor.
