A non-planar surface projecting system, an auto-calibration method thereof and an auto-calibration device thereof are provided. In an embodiment of the non-planar surface auto-calibration method, a depth map of a projection surface is measured, a corresponding area corresponding to a projecting area and a depth sensing area is calibrated; and in the corresponding area, an interactive content is adjusted according to the depth map of the projection surface.

The present disclosure provides a device, in particular a multifocal display device. The device includes: a display element configured to generate an image; and a controller configured to control the display element according to at least a first bit sequence provided over a first determined time period and a second bit sequence provided over a second determined time period, in order to generate the image with one or more colors, the bit sequences including for each color a number of bits of different significance. Moreover, the device is configured to generate the first bit sequence from an original bit sequence based on discarding at least one bit of a color and to generate the second bit sequence from the original bit sequence based on discarding at least one other bit of the color.

A system for generating high-resolution de-warped omni-directional stereo image from captured omni-directional stereo image by correcting optical distortions using projection patterns is provided. The system includes a projection pattern capturing arrangement, a projector or a display, and a de-warping server. The projection pattern capturing arrangement includes one or more omnidirectional cameras to capture projection patterns from the captured omni-directional stereo image from each omni-directional stereo camera. The projector or the display displays the projection patterns. The de-warping server obtain the projection patterns and processes the projection patterns to generate high resolution de-warped omni-directional stereo image by correcting optical distortions in the captured omni-directional stereo image and mapping the captured omni-directional stereo image and the high resolution de-warped omni-directional stereo image.

A new projector design combines one spatial light modulator that affects only the phase of the illumination, and one spatial light modulator that only affects its amplitude (intensity). The phase-only modulator curves the wavefront of light and acts as a pre-modulator for a conventional amplitude modulator. This approach works with both white light and laser illumination, generating a coarse image representation efficiently, thus enabling, within a single image frame, significantly elevated highlights as well as darker black levels while reducing the overall light source power requirements.

A vehicle lamp is provided, which is capable of changing the clearness of a contrast boundary line correspondingly to a traveling state or a traveling environment of a vehicle. The vehicle lamp is mounted in a vehicle and configured to form a prescribed light distribution pattern including a contrast boundary line, the vehicle lamp including: a sensor provided in the vehicle; and a clearness control unit configured to change clearness of the contrast boundary line correspondingly to a detection result of the sensor.

A projector is provided with: an image processing unit that image-processes inputted image signals; an image display element, to which the image signals image-processed by means of the image processing unit are inputted, and which generates an optical image; and a projection optical system that projects, to a projection surface, the optical image generated by means of the image display element. The image processing unit has an image correction unit for reducing blurring of an image to be projected by means of the projection optical system, and the image correction unit changes the black luminance level of the image signals.

A method of inspecting a part comprising projecting a life sized image of at least one portion of a selected part file onto a flat surface with a projector, placing a part adjacent to the flat surface, comparing the part to the life sized image of the at least one portion of the selected part file, receiving at least one command at a user interface to modify the life sized image such that it matches the part, and adjusting a manufacturing process based on the at least one command using a control system.

A locally dimmed display has a spatial light modulator illuminated by a light source. The spatial light modulator is illuminated with a low resolution version of a desired image. The illumination may comprise a series of lighting elements that vary smoothly from one element to another at the spatial light modulator.

A keyboard device includes a keyboard body including a plurality of keys. A projector is disposed in the keyboard body for receiving and transforming an image signal into a projection frame, and projecting the projection frame on a projection plane. A vibration sensor is disposed in the keyboard body, and generates a vibration signal in response to a vibration of the keyboard body. A microprocessor is in communication with the vibration sensor and the projector, dynamically adjusts the image signal according to the vibration signal, and outputs the adjusted image signal to the projector to generate the projection frame corresponding to the adjusted image signal. The shaking problem of the projection frame can thus be ameliorated.
