A projector for generating a frame of an image is disclosed, comprising an array of elements arranged in a plane, each element comprising at least three LEDs which have different respective colours, and an array of collector structures, each configured to receive light from a single LED at any one time and reduce the angle over which the LED emits light. A projector unit is configured to receive the light from the array of collector structures and collimate the light such that a full colour frame is formed from combining a plurality of subframes formed through a spatial movement of the array of elements with respect to the array of collector structures such that each collector structure receives light from a different LED during each subframe, and/or a displacement of the light emitted from each LED such that the light from each LED illuminates multiple pixels of the frame.

Various embodiments described herein provide multi-projector (i.e., two or more) imaging apparatuses utilizing integrated illumination-aimer optics. Embodiments of the present disclosure minimize irreparable component offset to improve overall accuracy associated with the functioning of the apparatuses.

The light source assembly is fixed to the support member by coupling the holding member to the receiving surface at a contact portion with the receiving surface. The receiving surface has a portion located on a side away from the optical axis with respect to a coupling part with the holding member.

[Problem] An information processing apparatus, an information processing method, and a recording medium with which a user can recognize a boundary of a drivable range by feedback for a projection specification position by the user to facilitate determination of and search for a projection position are provided. [Solution] The information processing apparatus includes a controller configured to perform processing of outputting feedback indicating an effect corresponding to a boundary of a drivable region of a drive-type projector in a projection environment space in accordance with a state of a projection specification position specified by a user for the drivable region, the state being determined based on the drivable region and the projection specification position.

Devices and methods for improving the flow of traffic at an intersection are disclosed, such as a traffic light assistance system comprising a light emitter, a light-directing device, a vehicle sensor, a traffic signal detector, and a control unit. The traffic light assistance system can be configured to detect a vehicle and direct projected light toward said vehicle to indicate a change of status of a traffic light. Such devices and methods can alert an operator of a vehicle to a change of status of a traffic light, such as a traffic signal turning green, and indicating that the operator should accelerate the vehicle. By providing means to alert otherwise distracted or inattentive drivers, time spent in traffic can be reduced.

An optical system (300) includes an optical modulation element (103) to reflect an incident light (250) in a different direction, and an illumination optical system (301) through which light emitted from a light source (101) is emitted toward the optical modulation element (103). The illumination optical system (301) includes a lens array (14A, 14B), a lens (15) disposed in an order listed from an upstream side of an optical path, and a shielding part (50) disposed upstream from the lens (15) on the optical path. The shielding part (50) shields light incident on an effective diameter of the lens (15). In a direction perpendicular to an optical axis of the light emitted from the light source (101), the optical axis (101A) is shifted from a center position (15M) of the effective diameter of the lens (15) in an opposite direction with reference to the shielding part (50).
