An image forming apparatus includes a network interface, an operation panel including a touch panel, and a controller. The controller is configured to provide a mobile input function to a mobile terminal via the network interface. In response to accepting a first operation to the operation panel with a local operation screen not displayed on the touch panel, the controller causes the touch panel to display the local operation screen, and thereafter switches the local operation screen on the touch panel to a standby screen after waiting until a continuous time with no operation to the touch panel exceeds a first threshold time. In response to accepting a second operation to the operation panel with the local operation screen not displayed on the touch panel, the controller causes the touch panel to display the standby screen without waiting for the first threshold time to elapse.

An image forming apparatus measures the distance between the image forming apparatus and an object located in the periphery of the image forming apparatus each predetermined amount of time. Then, whether or not the object is a human is detected on the basis of the measured distance and a moving amount of the object each predetermined amount of time. Furthermore, the image forming apparatus controls the power supply state of the image forming apparatus in accordance with the result of the human detection.

An image forming apparatus includes an image forming section, a first detecting section, a second detecting section, a display section, and a control section. The first detecting section detects a person present within a predetermined range from the image forming apparatus. The second detecting section detects an eye gaze of the person detected by the first detecting section. When, during a power saving state of the image forming apparatus, the first detecting section detects a person and the second detecting section detects an eye gaze of the person directed in a predetermined direction, the control section wakes up the image forming apparatus from the power saving state and allows the display section to display a predetermined screen according to the direction of the person's eye gaze detected by the second detecting section.

An information processing apparatus includes a detection unit and a control unit. The detection unit detects motion of a user made between a display surface that displays an image of an object to be operated and the user. The motion is made without contact with the display surface. The control unit instructs the object to execute an operation corresponding to the detected motion of the user.

An information processing apparatus that is used in contact with a user includes a detection unit and a control unit. The detection unit detects a motion of the user in a real space performed without contacting an object that is present in the real space. The control unit instructs the object to execute a specific function in the case where plural motions by users for a common object are detected. The specific function is correlated with the plural motions.

A sensor apparatus includes a photosensitive sensor, a cover, and a moving mechanism. The photosensitive sensor includes a first lens and a second lens which focus on a photosensitive element. The cover includes a first slit arranged on an optical axis of the first lens and a second slit arranged on an optical axis of the second lens. The moving mechanism is configured to move the photosensitive sensor and the cover relative to each other so that the second slit is arranged on the optical axis of the first lens.

An image forming apparatus measures the distance between the image forming apparatus and an object located in the periphery of the image forming apparatus each predetermined amount of time. Then, whether or not the object is a human is detected on the basis of the measured distance and a moving amount of the object each predetermined amount of time. Furthermore, the image forming apparatus controls the power supply state of the image forming apparatus in accordance with the result of the human detection.

On a touch-panel display of an image forming apparatus, a function selecting area and a preview area are displayed next to each other. On the function selecting area, a function setting menu is displayed in one display mode among an icon mode in which only a group of icons are displayed, a regular mode in which a group of icons and a group of texts are displayed, and an express mode in which a group of icons, a group of texts and a group of function setting buttons are displayed. In the icon mode, detailed preview information is displayed on a large preview area, and in the express mode, detailed function selecting information is displayed on a large function selecting area.

The image forming apparatus according to the embodiment includes a first sensor unit, a setting unit, and a notification unit. The first sensor unit is configured to detect a person who enters a detection range and specify a position of the person. If an error related to image processing or image formation occurs, the setting unit is configured to set a notification direction according to the position of the person who enters the detection range. The notification unit is configured to notify an occurrence of the error in the notification direction based on setting by the setting unit.

An image processing method for processing a display image includes using an image forming apparatus which includes a position detector detecting a position of contact with a display screen and forms an image on a recording medium based on a display image displayed on the display screen. The display image includes an object image indicative of an object for an image formation and a medium image indicative of the recording medium, and the image processing method includes modifying magnification of the object image with respect to the medium image, without modifying the medium image, based on contact positions of two points detected by the position detector.
