Abstract: A method includes capturing, by a camera disposed behind a display panel of an electronic device, an original image through a semi-transparent pixel region of the display panel. The original image includes one or more color components. The method further includes determining, for a plurality of pixel regions of the original image, a point spread function (PSF) for each of the one or more color components. The method further includes performing, for the plurality of pixel regions of the original image, a deconvolution of each of the one or more color components of the original image based at least in part on their respective PSFs. The method thus includes generating a reconstructed image corresponding to the original image based on the deconvolutions of the one or more color components of the plurality of pixel regions of the original image.

Abstract: In exemplary embodiments of this invention, an inertial measurement unit (IMU) includes a cantilevered proof mass and electrostatic drive. The electrostatic drive puts the proof mass into a controlled trajectory in which it oscillates rapidly, for example, by vibrating back and forth in a plane or traveling in a circular or elliptical orbit. The IMU detects lateral or angular acceleration of the IMU, by measuring the perturbations of the proof mass trajectory from the expected motion in a fixed, non-rotating inertial frame. In exemplary embodiments of this invention, the proof mass position and motion are measured by methods of differential potential measurement (with constant slope voltage), differential displacement current measurement, or phase-sensitive or synchronous detection of motion.
