Abstract: Provided is an image forming apparatus that shortens the waiting time of a user when returning from a power saving state to an operating state while suppressing power consumption. A return control unit switches a specific device from the power saving state to the operating state when a person is detected by a motion sensor in a situation where the specific device is in the power saving state. A performance recording unit records data of an actual start-up time, which represents a time required to start a specific program when the specific device switches from the power saving state to the operating state, in a non-volatile storage device. A sensitivity setting unit sets the sensitivity of the motion sensor according to the actual start-up time when the specific device is in the power saving state.

Abstract: An image forming apparatus includes a communication device, a received data processing portion, a human detection sensor, a sensitivity setting portion, a rest control portion, and a return control portion. The sensitivity setting portion sets, based on content of the job data, the sensitivity of the human detection sensor for a time when specific devices including the received data processing portion are in a predetermined rest state. The rest control portion causes the specific devices to transit to the rest state when a predetermined rest condition is satisfied. The return control portion causes the specific devices to transit from the rest state to a return state when the human detection sensor detects a human body in the situation where the specific devices are in the rest state, wherein larger power is consumed in the return state than in the rest state.

Abstract: An image forming apparatus operates in a normal mode in a first electric power state and in a power saving mode in which more electric power is saved than in the first electric power state. The image forming apparatus includes a motion sensor, an operation section, and a controller. The controller executes a first timer process in response to receipt of the detection signal and executes a second timer process in response to receipt of the operation signal. At a time when a first period elapses indicating that the first timer process times out, the controller transitions from the normal mode to the power saving mode. At a time when a second period elapses indicating that the second timer process times out, the controller transitions from the normal mode to the power saving mode. The first period is shorter than the second period.

Abstract: An image forming apparatus includes a sensor, an operation section, and a controller. The sensor detects a sensor target. The operation section receives an operation instruction. The controller executes a setting process for controlling the sensor. The setting process is a process to adjust a sensitivity of the sensor according to detection precision. The detection precision is a relationship in a first unit period between the number of times the sensor detects the sensor target and the number of times of the operation section receives the operation instruction.

Abstract: A controller of an information processing device changes a current state among standby states including a first standby state, a second standby state, and a third standby state, in which power consumption decreases in this order. When the non-operation duration runs for a first period, the controller changes the current state from the first standby state to the second standby state. When the non-operation duration subsequently runs for a second period, the controller changes the current state from the second standby state to the third standby state. When the sensor detects a detection target in the second standby state or the third standby state, the controller changes the current state to the first standby state. When the non-operation duration runs for a third period starting from state change, the controller changes the current state from the first standby state to the previous standby state.

Abstract: In an image forming apparatus, a 2D code detecting unit detects a 2-dimensional code in a document image to be printed. A divisional code distributing unit (a) removes the 2-dimensional code in the document image, (b) divides the 2-dimensional code into a predetermined number of divisional codes, (c) performs a zooming process and/or a rotation process for a part or all of the divisional codes, (d) distributes the divisional codes after the zooming process and/or the rotation process, and (e) generates and outputs a decode key that includes (e1) the number of the divisional codes, (e2) positions of the divisional codes, and (e3) a zooming ratio of the zooming process and/or a rotation angle of the rotation process. A printing device prints the document image in which the divisional codes are distributed.

Abstract: An information processing apparatus can be worn by a user of an image forming apparatus, and includes a camera, a visual line detecting portion, a target image recognizing portion, a positional condition determining portion, and a wireless communication portion. The target image recognizing portion, when a positional condition among setting conditions for image-formation-related processes is specified, recognizes an image of a specification target that is included in a visual field image photographed by the camera, the specification target being a target of specification of the positional condition. The positional condition determining portion determines a specified positional condition based on a position in the image of the specification target recognized by the target image recognizing portion, the position corresponding to the visual line direction detected by the visual line detecting portion.

Abstract: When a first recognition condition is satisfied, a target apparatus notification portion causes an image display portion to display a notification notifying that a target apparatus is recognized which exists at an azimuth of a line of sight of a user. The first recognition condition is that an apparatus image exists in a position corresponding to the line-of-sight direction in a field-of-view image taken by a camera, when a line-of-sight direction enters a gaze state under a situation that an image processing apparatus exists in an area where the wireless communication can be performed. An instruction screen control portion causes the image display portion to display an instruction screen for execution of a job, when a second recognition condition is satisfied. The second recognition condition is that the apparatus image exists in the field-of-view image within a short distance range of the target apparatus.
