Abstract: An electronic device includes a first non-contact detection sensor, a second non-contact detection sensor, a display, and a controller. The controller determines a first gesture and a second gesture by referring to the first non-contact detection sensor and a second non-contact detection sensor. The controller, when a first window and a second window are displayed on the display, allocates operation of the first window to the first gesture detected by the first non-contact detection sensor, and allocates operation of the second window to the second gesture detected by the second non-contact detection sensor.

Abstract: An electronic device includes a communication interface, a display, and a controller. The communication interface communicates with a movement detection apparatus including a motion sensor that detects a predetermined movement of a user. The controller activates the motion sensor when a screen displayed on the display is related to the predetermined movement. The predetermined movement includes a plurality of motions, the motion sensor includes a plurality of sensors that detect the plurality of motions, and when the screen displayed on the display is related to one motion among the plurality of motions, the controller activates the sensor that detects the one motion.

Abstract: An electronic device includes a display and a controller that controls screen display of the display. When the mode immediately before suspension of screen display of the display is a first mode, the controller displays a security lock screen before resuming screen display of the display, and when the mode immediately before suspension of screen display of the display is a second mode, the controller resumes screen display of the display while selectively causing the security lock screen not to be displayed.

Abstract: According to an aspect, a portable photographing device includes: an image capturing unit; a projecting unit for projecting an image; and a storing unit for storing an image captured by the image capturing unit. The projecting unit projects any of a first image captured by the image capturing unit, a second image related to the first image, and a third image obtained by synthesizing the first image with the second image as a projection image into a region which is different from an image capturing region of the photographing unit. The storing unit stores the first image in the projection of the projection image or the first image after the projection of the projection image.

Abstract: A method is provided. A command to correspond to a target speed of a motor is received. A rotational speed of the motor is measured, and a brake-to-off ratio for a braking interval is calculated based at least in part on the rotation speed, the target speed, a braking parameter. An off state for an inverter that is coupled to motor is induced during an off portion of the braking interval, and a brake signal is applied to the inverter during a braking portion of the braking interval.

Abstract: According to an aspect, a projector device includes an image projecting unit and a control unit. The image projecting unit projects an image. The control unit acquires brightness information of regions included in a projection surface on which the image projecting unit can project the image, and causes the image projecting unit to project, based on the brightness information of the regions, the image on a low-brightness region, among the regions, whose brightness is lower than that of another region.

Abstract: A mobile electronic device 10 includes a projector 34, a camera 36, and a processing unit 22. The projector 34 projects an image, and the camera 36 captures the image projected by the projector 34. Based on first image information for causing the projector 34 to project a predetermined image and second image information obtained by capturing the image projected by the projector 34 based on the first image information by the camera 36, the processing unit 22 determines whether the projector 34 projects the predetermined image. When determining that the projector 34 fails to project the predetermined image, the processing unit 22 suppresses output of the projector 34 for projecting the image.

Abstract: An image projecting apparatus for projecting an image includes a light source, a light emitting port, an emitting unit, and a control unit. The emitting unit causes the light emitted from the light source to be emitted from the light emitting port in such a manner that an emission direction of the light emitted from the light emitting port is variable. The control unit controls the light source and the emitting unit to switch between a first projection mode and a second projection mode. When the image projecting apparatus is placed on a horizontal plane, the emission direction is a front direction of the light emitting port or obliquely upward with respect to the horizontal plane in the first projection mode, and the emission direction is obliquely downward with respect to the horizontal plane in the second projection mode.

The mobile electronic device includes an image projector that projects an image, a detector that detects a specific change in an irradiation area of light irradiated from the image projector or in a predetermined area including the irradiation area, and a control unit that controls the operation of the image projector. The task is solved in such a manner that when the detector detects the specific change, the control unit causes the image projector to stop emission of light therefrom, or to reduce an amount of light emitted therefrom.
