A display system replacing a side mirror includes: a camera unit including cameras provided on both side surfaces of a vehicle and obtaining a rear-view image; a display unit outputting the rear-view image obtained by the camera unit; a driving condition detector detecting a driving condition of the vehicle; and a controller controlling output brightness of the display unit on the basis of the driving condition of the vehicle.

An HUD to be built in a construction machine includes an overlapping area detecting unit that detects a first overlapping area of a projection area and a bucket observed from a driver's seat; and a display control unit. In a state where a distance between a second overlapping area and the first overlapping area exceeds a threshold, the second overlapping area being an overlapping area of the projection area and a structure observed from the driver's seat, the display control unit performs tracking control in which a projection display unit is caused to display a virtual image based on operation support information while retaining a predetermined positional relationship with the first overlapping area. In a state where the distance is less than or equal to the threshold, the display control unit selects and performs either first control or the tracking control.

Provided is a head-up display device wherein in a state where a light-receiving unit is connected to a control substrate, a lid can be easily mounted to a case. Housed in a case of a head-up display device are a substrate for controlling a projector and a reflection unit for reflecting light projected thereon by the projector. The reflection unit is configured to have a reflecting mirror that is held by a holder, while the substrate is connected, via a connection member, with a light-receiving unit for detecting light from outside. The light-receiving unit is configured to have a light-receiving sensor that is held by a sensor holding part. The sensor holding part for holding the light-receiving sensor is held by the holder.

A vehicle display control device, when a steering wheel is at a steering angle position of a neutral position or the vicinity thereof, if a right hand sensor detects gripping of the steering wheel, turns off light sources of memory buttons and operation buttons that can be operated with a right hand, and if a left hand sensor detects the gripping, turns off a light source of air conditioning related buttons and hides touch buttons of a touch panel display that can be operated with a left hand. The vehicle display control device, if the right hand sensor does not detect the gripping, turns on the light sources of the memory buttons and the operation buttons, and if the left hand sensor does not detect the gripping, turns on the light source of the air conditioning related buttons and displays the touch buttons on the touch panel display.

An image projection apparatus includes an intermediate image forming member configured to form an intermediate image from light emitted by a light source device; and a plural-film optical member on which image light that forms the intermediate image is incident. The image projection apparatus uses the image light that is incident on the plural-film optical member to project an image, an image rotational position relationship in a rotational direction around an image center axis between the image that is projected and the intermediate image is such that a difference is present in image rotational positions, and the plural-film optical member is set in such a manner that a polarization axis of the image light incident on the plural-film optical member is parallel or perpendicular to a plane of incidence of the image light with respect to the plural-film optical member.

An electronic device, in disclosed embodiments, includes an antenna, transceiver circuitry coupled to the antenna, a memory configured to store a first operation key and instructions, and a processor coupled to the transceiver and to the memory. The processor is configured to execute the instructions stored in the memory to cause the electronic device to, in response to receiving a first transmission containing an encrypted version of a second operation key that is encrypted by the first operation key, decrypt the encrypted version of the second operation key using the first operation key to recover the second operation key, store the second operation key in the memory, transmitting, by a transmitter of the electronic device, a second transmission that contains the first operation key and a command.

A dashboard display for a vehicle, and including a light source unit including a plurality of light sources disposed in a matrix form; a display unit configured to display speedometer information using light provided from the light source unit; a needle positioned on the speedometer information and rotatably moving according to a speed of the vehicle; and a processor configured to control the light source unit to emit a predetermined brightness in a region at least partially surrounding the needle, and vary the region at least partially surrounding the needle according to a position of the needle.

A luminance control device (1) calculates a pupil diameter difference, which is the difference between a pupil diameter (R) measured by a measurement unit (11) and a pupil diameter (r) estimated by a pupil diameter estimation unit (13), and when it is determined, on the basis of the pupil diameter difference, that a dark portion is being focused on, the luminance control device (1) executes a luminance control method for outputting control information for controlling a control subject so that the luminance is increased in at least one display region in which an image is displayed of the surroundings of a vehicle (8) imaged by at least one imaging device.

The invention relates to a steering module (8) for a motor vehicle (1), the steering module (8) comprising an optical signaling unit (14), which optically indicates an operating state of the motor vehicle (1), wherein the optical signaling unit (14) comprises at least one light source (15) and a light guide (16), by which the light emitted by the light source (15) with a main radiation direction (20) is capable of being deflected in an exit direction which is different from the main radiation direction (20) and the light exits in this exit direction (19) from an emission surface (18) from the light guide (16), wherein the light guide (16) is shaped in such a way that light rays of the coupled-in light are reflected therein at least twice so that the exit direction (19) is opposite to the main radiation direction (20).

A vehicle display control device, includes a memory; and a processor coupled to the memory. The processor is configured to cause a display unit provided in a vehicle cabin to display an inducement image requesting that an occupant grip a steering wheel in a case in which it is necessary for the occupant to grip the steering wheel, and cause the display unit to display the inducement image more prominently in a case of requesting that the occupant grip the steering wheel before the vehicle switches from an autonomous driving mode to a manual driving mode as the vehicle is continuing to drive autonomously, than in a case of requesting that the occupant continue to grip the steering wheel as the vehicle is continuing to drive autonomously.
