Abstract: Various techniques pertaining to non-coherent noise reduction for audio enhancement on a multi-microphone mobile device are proposed. A processor receives a plurality of signals from a plurality of audio sensors corresponding to a plurality of channels responsive to sensing by the plurality of audio sensors. The processor then performs a non-coherent noise reduction on one or more signals of the plurality of signals to suppress one or more non-coherent noises in each of the one or more signals based on a respective signal-to-noise ratio (SNR) associated with each of the one or more signals. The processor further combines the plurality of signals subsequent the noise reduction to generate an output signal.

Abstract: The present invention discloses a method and an apparatus for converting 2D images into 3D images, comprising: an original image, serving as first-eye image information; an in-depth image, serving as second-eye image information, and the in-depth image having a primary target area and a secondary target area, and the secondary target area being disposed at a position extended from an edge of the primary target area, and the primary target area using finer pixels as a computing unit for a 2D-image object depth computation, and the secondary target area using pixels larger than those of the primary target area as a computing unit for the 2D-image object depth computation, wherein the original image and the in-depth image are combined into a 3D image, such that the 3D images can be produced by lower-priced computing resources.

Abstract: A light emitting module for producing a visible light by passive ultraviolet excitation includes an excitation light source member and at least one layer of wavelength modulation matrix. The excitation light source member produces an ultraviolet light with a specific wavelength range. The wavelength modulation matrix adopts an organic polymer as a carrier, and the carrier adds a composite material composed of an organic wavelength modulation material, a quantum dot luminescence color rendering modulation material and a nanoparticle brightness enhancement luminescence powder, and the composite material is cured and formed by coating, injection molding, thin film lamination, screen printing or thick film printing, so that when the wavelength modulation matrix is projected by an ultraviolet light beam emitted by the excitation light source member, a light including a visible light is produced.
