The disclosure discloses a control device for a robot to tease a pet and a mobile robot. The primary sensor is configured to continuously collect a preset number of frames of pet motion images in each motion cycle. The state recognizer is configured to judge the matching between the pet motion images continuously collected by the primary sensor and a pre-stored digital image of pet behavior, and then parse a matching result into behavior state parameters of a pet. The behavior interferometer is configured to adjust and control a behavior state of the pet according to the behavior state parameters and an additional road sign image provided by the secondary sensor. The laser projector is configured to project a laser beam to form a structural light spot, so that the pet changes toward the behavior state adjusted by the behavior interferometer.

A projector includes: an electro-optical panel including a plurality of pixels; an optical-path shift element configured to change an optical path of light emitted from the plurality of pixels; and an image processing circuit configured to, in a unit period, supply an image signal to the plurality of pixels in an order, the unit period being included in one frame period for displaying an image of one frame indicated by an input image signal, the image signal corresponding to the plurality of pixels and being generated on a basis of the input image signal, in which the image processing circuit includes an adjustment circuit configured to adjust a response velocity of the plurality of pixels when the image displayed by the electro-optical panel is switched, on a basis of an order of supply of the image signal or of a position of a pixel at the electro-optical panel.

A method and system for optimizing projection surfaces for generating visible images. The projection system may include a projector that emits light in the ultraviolet range and a screen in optical communication with the projector. The screen includes a visible light absorbing layer, a transparent layer positioned over the visible light absorbing layer, and a plurality of fluorescent colorants printed on the transparent layer in a predetermined pattern, where the light emitted by the projector excites the fluorescent colorants to emit visible light forming the visible images. The predetermined pattern can be optimized to increase a color gamut of the formed images by varying surface coverage ratios of the fluorescent colorants.

A drawing apparatus includes a laser light source unit configured to output laser light; a scanning mirror unit configured to reflect and scan the laser light; a drawing control unit configured to control an output value of the laser light of the laser light source unit based on display image data so that a display image is drawn by the laser light in a range scanned by the scanning mirror unit; and an output adjustment control unit configured to control the laser light source unit so that characteristic detection laser light for adjusting the output value is output outside a range in which the display image is drawn inside the range scanned by the scanning mirror unit. The output adjustment control unit controls the characteristic detection laser light to be output based on a display color at an end part of the display image.

Undesirably high energy-consumption in illuminating devices can be caused at least in part by wasted (attenuated) light. Optically efficient illumination systems that may be used to project light, including images, use light redirection. Phase modulating devices may be applied to create desired light fields. Some embodiments provide dual or multiple modulation display or projection systems in which some or all of the modulators not only attenuate amplitude, but also amplify amplitude, or change the phase, frequency and polarization of the light provided by the light source.

A novel projection system includes first and second light sources (e.g., sets of lasers), a spatial light modulator (SLM) that receives light from the first light source, and a beam steering device that receives light from the second light source and steers the light to highlight regions of the SLM. The SLM then modulates the light from both light sources to generate a highlighted imaging beam which can then be projected on a viewing surface. The highlighted imaging beam can represent a highlighted 2D image or a highlighted left- or right-eye view of a 3D image. The projection system thus improves peak brightness in the displayed highlighted images without incorporating a separate highlight projector or other expensive equipment. Methods for highlighting projected images are also described.

An information processing device which controls one projector and another projector includes: a display unit which displays a first operation screen for managing the one projector and a second operation screen for managing the another projector; an input unit which accepts an operation on the first operation screen and the second operation screen; and a control unit which controls the one projector and the another projector, based on the operation accepted by the input unit. When the information processing device is switched from a first state where the first operation screen is operable to a second state where the second operation screen is operable, the control unit causes the second operation screen where an item corresponding to a predetermined item selected on the first operation screen in the first state is selected, to be displayed in the second state.

A multi-beam scanning system and methods of operating the same to compensate for distortion are provided. Generally, the method involves illuminating a spatial light modulator including SLM pixels arranged in parallel, each pixel including a multiple address pixels. Drive signals including image data are provided to the pixels to generate beams of modulated light reflected therefrom, which is scanned to a linear swath of a two-dimensional imaging plane using a collimate lens, a scan mirror moved about a first axis, and an imaging lens. The swath is scanned across the imaging plane in a direction orthogonal to a long axis of the swath by moving the scan mirror about a second axis. To compensate for distortion along the long axis of the swath compensated image data is provided to at least some of the address pixels generating beams of modulated light distal from an optical axis of the imaging lens.

An automotive animated image projector comprises a light source emitting a light beam, a microelectromechanical system projector aligned to receive the light beam and project an animated image onto a target surface, a computer system programmed to control the light source and the microelectromechanical system with commands to produce the animated image, and a transmission link for sending the commands from the computer system to the light source and the microelectromechanical system projector. In some embodiments, the target surface is the ground next to a vehicle and the animated image illuminates the ground to assist entry into, and exit from, the vehicle. A method is also provided of projecting an animated image from an automotive animated image projector. The method comprises generating a light beam, directing the light beam onto a microelectromechanical system projector, manipulating the light beam by dynamically controlling the microelectromechanical system projector to generate animated images that are projected onto a target surface.
