Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the following examples are not intended to limit the scope of the appended claims, and not all combinations of features described in the examples are essential to the solution of the present invention.

[0023] Image forming device structure

[0024] Figure 1A and Figure 1B are a side view and a top view of the appearance of the image forming apparatus 10 according to the embodiment, respectively. The image forming apparatus 10 has a plurality of functions such as a printing function, a scanning function, a copying function, and a facsimile (FAX) function. The image forming apparatus 10 includes a human detection sensor 16 as a sensor for detecting an object existing around the image forming apparatus. The human detection sensor 16 is used to detect a human (user) approaching the image forming apparatus 10 . The signal output from t...

Abstract

An information processing apparatus obtains a measurement value D of the distance between the object and information processing apparatus using a human detection sensor, and detects the object as a user (user detection state ST3) by comparing the measurement value D and a predetermined threshold value. The power mode of the information processing apparatus is set to a standby mode if a user has been detected, and is set to a sleep mode if a user has not been detected. If a state in which a user has been detected continues for a predetermined time, the information processing apparatus changes the sensitivity of the human detection sensor by changing the threshold value for the detection state determination such that the object detected by the human detection sensor is no longer detected as a user.

Description

technical field [0001] The invention relates to an information processing device and a control method thereof. Background technique [0002] There is known an image forming apparatus including a person detection sensor for detecting a person (user) approaching the image forming apparatus. Japanese Patent Laid-Open No. 2012-203132 discloses a technique in which an image forming apparatus including such a human detection sensor returns from a power saving state when the human detection sensor detects a person approaching the image forming apparatus. [0003] In Japanese Patent Laid-Open No. 2012-203132, the disclosed image forming apparatus changes the power state of the image forming apparatus from a power saving state to a standby state if a human detection sensor detects a human being. For this reason, if a certain type of object persists in front of the image forming apparatus, such as a case where a person stands in front of the image forming apparatus or an object is pl...
