COMPLIANCE VOLTAGE BASED ON DIODE OUTPUT BRIGHTNESS
A method for operating a display comprising a plurality of emission diodes. For each emission diode, an output brightness of the emission diode is monitored over a range of compliance voltages. Based on the monitored output brightness of the emission diode, an inflection voltage is determined. At the inflection voltage, increasing a commanded compliance voltage does not yield an above-threshold increase in output brightness. Further, decreasing the commanded compliance voltage from the inflection voltage yields an above-threshold decrease in output brightness. In response to receiving a request for the emission diode to operate at a peak output brightness, an applied compliance voltage is commanded that is within a threshold voltage of the inflection point voltage.
DISPLAY DEVICE AND DISPLAY SYSTEM
A display device is provided with an input unit for inputting a detection signal from a detection unit capable of detecting the brightness of ambient light around a dimming member. The display device is also provided with a control unit which, on the basis of the detection signal input by the input unit, controls at least one of the optical transmittance of the dimming member and the operation of a projector to adjust an image projected onto the dimming member to a display state corresponding to the brightness of the ambient light.
PROJECTOR, METHOD FOR CONTROLLING PROJECTOR, AND INFORMATION PROCESSING APPARATUS
A method for controlling a projector including a light source, the method including identifying the state of the light source, generating a correction parameter based on the state of the light source, and correcting an image projected from the projector based on the correction parameter.
DEPTH-BASED PROJECTION OF IMAGE-BASED CONTENT
A projection system and method for depth-based projection of image-based content is provided. The projection system receives a sequence of image frames to be projected on a physical surface of a three-dimensional (3D) structure. The projection system controls a depth sensor to acquire depth data associated with the physical surface and feeds a first input including the acquired depth data and a first image frame of the received sequence of image frames to a neural network-based model. The projection system further receives a set of geometric correction values as a first output of the neural network-based model for the fed first input and modifies the first image frame based on the received set of geometric correction values. The projection system further controls the illumination circuitry to project the modified first image frame onto the physical surface.
Housing structures and input-output devices for electronic devices
An electronic device may have input-output devices such as sensors, displays, wireless circuitry, and other electronic components mounted within a housing. The housing may have opposing front and rear walls. A display may be formed on a front side of the device and may be overlapped by a front housing wall such as a glass layer. Sensors and other components may be formed on a rear side of the device and may be overlapped by a rear housing wall. The rear housing wall may have a glass portion or other transparent structure through which projectors project images onto nearby surfaces and through which image sensors and other optical sensors receive light. The housing may be supported by a stand. An electrical component in the stand may interact with an electronic device on the stand. Wireless circuitry in an external item may wirelessly couple to wireless circuitry within the housing.
Projector light source dimming using metadata from future frames
A projection display system comprises a light source configured to emit a light in response to a content data; an optical modulator configured to modulate the light; and a controller configured to adjust a light level of the projection display system based on the content data and a metadata relating to a future frame, thereby to reduce a perceptibility of a visual artifact.
LASER PROJECTOR SYSTEM
A light projector and method of aligning the light projector is provided. A light projector steers an outgoing beam of light onto an object, passing light returned from the object through a focusing lens onto an optical detector. The light projector may generate a light pattern or template by rapidly moving the outgoing beam of light along a path on a surface. To place the light pattern/template in a desired location, the light projector may be aligned with an electronic model.
Information processing apparatus, information processing method, and program for controlling input position in an overlap region
It is desirable to provide a technology for enhancing quality of a displayed image in an overlap region among a plurality of display regions even in a case where a position of the displayed image is changed. There is provided an information processing apparatus including a display controller (134) that controls display of a displayed image in at least one display region of a plurality of display regions on the basis of an input position detected on the basis of a captured image, in which the plurality of display regions includes a first display region and a second display region, and in a case where the input position has moved to an overlap region where the first display region and the second display region overlap with each other, the display controller controls display of the displayed image in the overlap region on the basis of the input position before moving to the overlap region.
METHOD AND DEVICE FOR ALIGNING COLOR CHANNELS
A method of aligning a plurality of color channels of a projector is provided. The method includes: for each color channel, (i) projecting test pattern on a surface; (ii) capturing image of the test pattern generated on the surface; and (iii) adding the captured image to an image set. Once the captured images for each color channel are added to an image set, identifying a reference position based on the image set. This is followed by processing the image set to estimate a divergence of the respective test patterns for each color channel with respect to the reference position, followed by computing a corrective function for each color channel and applying the respective corrective function to each color channel to align the color channel to the reference position.
Optical power reduction by masking pixels of image content
A scanning laser projection system includes a virtual protective housing circuit to automatically reduce accessible emissions of visible laser light by decimating areas of a projected image to reduce optical power exposure levels for safety, comfort, aesthetic, or system classification purposes. IR laser light pulses are scanned in a field of view, and a percentage of visible laser light pulses are blanked based on attributes of reflections of the IR laser light pulses.
