A vehicular heads-up-display system includes an apparatus having a base configured to receive and maintain a pico-projector case in combination with a handheld electronic device, and to output optical transmissions from the pico-projector case to an at least partially reflective surface to form a heads-up display. The partially reflective surface may be a combiner and/or mirror coupled to a base comprising the holder. The handheld electronic device may be a smartphone. For example, the system can be used to cause a pico-projector to project information from a smartphone to a partially reflective mirror for viewing by a vehicle operator.

A light source unit includes a green light source, a red light source, a blue light source, and a condenser lens system that condenses green light and red light at positions different from each other.

The present application discloses a beam combining device, which includes a reflective diffractive grating surface configured to combine a first, a second and a third incident light beam having different colors to a single diffracted mixed-color light beam when impinging on the reflective diffractive grating surface, wherein a profile of the grating surface is configured according to an optimization criterion with respect to a diffraction efficiency.

A method for adjusting a projection picture includes: receiving a first image, captured by a first imaging module, of a position where the projection picture is located, and a second image, captured by a second imaging module, of surroundings of a projection device; identifying, based on the first image, whether a projection shade is present within a projection range of a projecting module; identifying position information of a projection shade in response to the projection shade being present; identifying, based on the second image, movable directions and movable distances of the projection device; and controlling, based on the position information of the projection shade and the movable directions of the projection device and the movable distances in the movable directions, the position adjusting module to adjust the projection device, such that the projection device escapes from the projection shade and a complete projection picture is acquired.

A system for displaying a simulated room can comprise at least one projector, at least one wall structure element, at least one physical object, and a room customization station. The room customization station can be configured to permit viewing images of selectable products and selecting at least one of the selectable products to be displayed on at least one of the at least one wall structure element or the at least one physical object. The projector(s) can be adapted to display the selectable product(s) on at least one of the at least one wall structure element or the physical object(s). The physical object can be adjustable in size to correspond to different sizes of selectable products. The system can further include at least one physical accessory adapted to be placed in the simulated room to facilitate visualization of how the at least one physical accessory would appear in the presence of the simulated room and the at least one selectable product. In some embodiments, the room customization station can be configured to prevent at least one portion of the images of the selectable products from being projected by the projector(s) onto a physical feature in the simulated room and allow other portions of the images of the selectable products to be projected into at least a portion of the simulated room located around the physical feature.

An implant that is to be implanted inside the eye of a person contains a laser projection scanning subsystem that is configured to “paint” an image of the scene that is before the person, on the retina. The image of the scene may be acquired by a digital camera that is attached to a head unit that may be worn by the person, and then transmitted to the implant. Other aspects are also described and claimed.

An input device with a projecting function is provided, including: a first input device and a second input device. The first input device has a first projection unit, and the second input device has a second projection unit. The first projection unit and the second projection unit are configured to execute 2D projection or 3D projection. When a projection direction of the first projection unit is the same as that of the second projection unit, the first projection unit and the second projection unit execute the 2D projection. When the projection direction of the first projection unit is perpendicular to that of the second projection unit, the first projection unit and the second projection unit execute the 3D projection. The present disclosure provides a relatively sharp 2D projected image and a function of simplifying a structure of an input device.

Color images designed to be displayed, for example, with a projector such as a laser pico projector, are subjected to gamut extension in respective iso-hue paths in the CIE1931xyY color space, operating for example, as follows: a plurality of iso-hue curves in the CIE1931xyY color space is determined; for the points subjected to gamut extension, the closest iso-hue curves are identified; and extension paths to be used for the operation of gamut extension are interpolated from said closest iso-hue curves.

To provide a wearable computer excellent in extendibility and capable of being stably worn. A main body 2 which is equipped with cases 4, 6 and a flexible arm 8 is ring shaped main body having a part opened. The case 4 includes therein a computer, etc. The case 6 includes therein a battery for supplying electric power to the computer, etc. The flexible arm 8 is flexible and thus can be easily deformed. A connector case 10 is provided at a center portion of the flexible arm 8. The connector case 10 is provided with connectors for external device connection 36, 36, . . . . In the present embodiment, a USB connector is employed as the connectors for external device connection 36, 36, . . . .

A projection display is provided with an imager that is implemented to generate individual images in a distribution of sub-areas of an imaging plane of the imager. The projection display also includes a multi-channel optics, which is configured to map one allocated sub-area of the imager each per channel, such that the mappings of the individual images are combined to an overall image in a projection area. At least some channels of the multi-channel optics are arranged along at least one curve which is similar to at least one elongated image feature of the overall image, so that a two-dimension anisotropic out-of-focus behavior of each projected image point is obtained. In this way, a large depth of focus range can be combined with relatively high projection brightness without having to accept losses with respect to the focused illustration of image features that are to be projected with sufficient focus.
