Abstract: A robot arm control device is proposed. The robot arm control device may include a memory. The device may also include an acquisition unit acquiring an arbitrary target image, a virtual canvas image in which a virtual drawing operation of a robot arm for the target image is reflected, and a virtual nib image of the robot arm whose position is changed as the virtual drawing operation is reflected in the virtual canvas image. The device may further include a processor configured to input the target image to the pre-trained learning model, determine a position change amount of the virtual nib image in the virtual canvas image using the pre-trained learning model, and output a joint angle change amount for driving the robot arm on the basis of the position change amount.

Abstract: In one implementation, a method of performing late-stage shift is performed at a device including a display, one or more processors, and non-transitory memory. The method includes generating, based on a first predicted pose of the device for a display time period, a first image. The method includes generating a mask indicating a first region of the first image and a second region of the first image. The method includes generating a second image by shifting, based on a second predicted pose of the device for the display time period, the first region of the first image without shifting the second region of the first image. The method includes displaying, on the display at the display time period, the second image.

Abstract: Technology is described for methods and systems for imaging an object (110). The method can include an image sensor (116) exposed to light (114) from an object (110) without passing the light through an image modification element. Light intensity of the light (114) can be stored as data in a medium. The image data can be analyzed at a processor (902) as a reconstructed image of the object (110).

Abstract: Systems, methods, and devices for reducing or eliminating image artifacts due to motion are provided. An electronic display may include an electronic display panel having a display pixel, an optical combiner that directs light from the display pixel toward a viewing area, and display driver circuitry. The display driver circuitry may receive image data that defines a total pulse width for one image frame. The display driver circuitry may cause the display pixel to emit light in in multiple pulses totaling to the total pulse width for the display pixel for one image frame.

Abstract: An imaging system that is translucent can be achieved by placing an image sensor (204) at one of more edges or periphery of a translucent window (202). A small fraction of light from the outside scene scatters off imperfections (218) in the translucent window (202) and reach the peripheral image sensor (204). Based on appropriate calibration of the response of point sources (206) from the outside scene, the full scene can be reconstructed computationally from the peripherally scattered light (210, 212). The technique can be extended to color, multi-spectral, light-field, 3D, and polarization selective imaging. Applications can include surveillance, imaging for autonomous agents, microscopy, etc.
