Abstract: An in-cabin monitoring system includes a camera which captures an image of an inside of a cabin of a vehicle, a light source which irradiates the inside of the cabin with light, and a controller which controls the camera and the light source. The light source is capable of emitting first light which is light to be emitted when checking whether a person is present using the camera and second light which is stronger than the first light. The controller captures an image of the inside of the cabin using the camera while causing the light source to emit the second light, before the person gets in the vehicle and after the person gets out of the vehicle.

Abstract: A display device has a movable screen that is movable in a movement direction, a drive controller, a projector, and a position detector. The drive controller moves the movable screen relative to a reference position set at a prescribed position in a movement range of the movable screen. The projector performs drawing on the movable screen by irradiating the movable screen with light used for scanning the movable screen and projects a virtual image onto a target space based on light that passes through the movable screen. The position detector executes position detection processing for detecting that the movable screen is located at a detection position set in relation to the prescribed position. The position detector moves the movable screen and executes the position detection processing in a non-display period in which the movable screen is not irradiated with light from the projector.

Abstract: A video display system includes: a screen on which an mage for displaying a virtual image is projected; a light source that emits laser light; a scanner that projects the image onto the screen by biaxially scanning the laser light onto the screen; and a controller that generates the image and controls the light source using an image signal for causing the generated image to be projected onto the screen by the laser light, and receives an input of sensing information measured using a temperature sensor and controls the scanner in accordance with the input sensing information. When the sensing information indicates a temperature outside a given temperature range, the controller causes the scanner to reduce an amplitude of the biaxial scanning in at least one axial direction to a smaller value than when the sensing information indicates a second brightness or a temperature within the given temperature range.

Abstract: A display system according to an aspect includes a screen, a drive control unit, and a projection unit. The drive control unit has the screen moved in a movement direction. The projection unit renders an image on the screen by irradiating the screen with a light beam that scans the screen and projects a virtual image onto a projection plane with the light beam transmitted through the screen. The drive control unit has the screen moved in the movement direction such that an optical path leading to a rendering point on the screen varies its length according to a tilt angle defined by the projection plane with respect to a reference plane.

Abstract: Imaging and display system includes: a display; an optical system including a first mirror and a second mirror; a housing; a light-transmissive cover transparent to light and disposed to cover at least part of an opening of the housing; and a driver monitoring camera supported by a supporting body connected outside of the housing. First light emitted from the display passes through the light-transmissive cover via the optical system, and is reflected by a windshield toward a direction of the user. The driver monitoring camera captures an image of a driver shown on the light-transmissive cover by second light from a direction of the driver reflected by the windshield toward a direction of the light-transmissive cover.

Abstract: An image display system includes a display unit displaying an image, a projection unit projecting in a target space a virtual image corresponding to the image with an output light of the display unit, a body unit provided thereto the display unit and the projection unit, and an image producing unit including a first correction unit and a second correction unit. The first correction unit performs a first correction processing of correcting, based on a first orientation signal indicative of a first orientation change of the body unit, a display position of the virtual image in the target space. The second correction unit performs a second correction processing of correcting, based on a second orientation signal indicative of a second orientation change of the body unit which is faster than the first orientation change, the display position of the virtual image in the target space.
