Content data representing content that includes at least one or more components is acquired. Projection area data representing a projection area is acquired. A deteriorated part, which is a part where a projection condition is deteriorated in the projection area, is identified based on the projection area data. A priority of the component included in the content is identified. Display deterioration of the content, which is caused by the deteriorated part, is suppressed based on a position of the identified deteriorated part in the projection area, the content data displayed on the projection area, a threshold according to the identified priority, and a degree of deterioration indicative of a level of deterioration of the component.

An image projector includes a spatial light modulator (SLM) with a two dimensional array of pixel elements controllable to modulate a property of light transmitted or reflected by the pixel elements. An illumination arrangement delivers illumination to the SLM. A collimating arrangement collimates illumination from the SLM to generate a collimated image directed to an exit stop. The illumination arrangement is configured to sequentially illuminate regions of the SLM, each corresponding to a multiple pixel elements. A controller synchronously controls the pixel elements and the illumination arrangement so as to project a collimated image with pixel intensities corresponding to a digital image.

A projector includes a first light source that emits a first light beam from a first light-emitting region including first light-emitting elements, and a second light source that emits a second light beam from a second light-emitting region including second light-emitting elements emitting light. Projector includes optical system that aligns traveling directions of first and second light beams, optical modulation device that adjusts first and second light beams based on image information, projection optical device, and control unit. The control unit changes a light-emitting position of the first light beam in the first light-emitting region to move an illumination region on an image forming region of the optical modulation device, and changes a light-emitting position of the second light beam in the second light-emitting region to move a second illumination region on the image forming region of the optical modulation device in the same direction as the first illumination region.

Systems, devices, and techniques related to matching features between a dynamic vision sensor and one or both of a dynamic projector or another dynamic vision sensor are discussed. Such techniques include casting a light pattern with projected features having differing temporal characteristics onto a scene and determining the correspondence(s) based on matching changes in detected luminance and temporal characteristics of the projected features.

A projection system can include a first modulator including a plurality of pixels in a first modulator surface, a second modulator including a plurality of pixels in a second modulator surface, and an intermediate imaging optical unit, which images the first modulator surface onto the second modulator surface, wherein the intermediate imaging optical unit includes a first lens having a convex side and wherein the convex side of the first lens is a free-form surface, which is not spherical and not rotationally symmetric and does not exhibit any mirror symmetry.

A projector includes an illumination waveguide layer, a collimation waveguide layer, and a spatial modulator. The illumination waveguide layer expands a light beam which is coupled to the spatial modulator. The spatial modulator modulates the expanded light beam to provide a line of light points of controllable brightness. The collimation waveguide collimates light of the light points to obtain a fan of collimated light beams. Each collimated light beam of the fan has an angle corresponding to a coordinate of the corresponding light point of the line. A tiltable reflector may be placed at the exit pupil to scan the fan of light beams in a plane non-parallel to the plane of the fan, thus providing a 2D image in angular domain. An array of Mach-Zehnder interferometers may be used in place of the illumination waveguide layer and the spatial modulator to provide the line of light points.

An optical engine unit and a projection system are provided. The optical engine unit includes a light splitting assembly, first and second spatial light modulators, and a light combining assembly. The light splitting assembly splits an illumination beam incident on the light splitting assembly into first and second light beams.
