  • Publication number: 20230267940
    Abstract: A method, executed by a processor for compressing an audio signal in multiple layers, may comprise: (a) restoring, in a highest layer, an input audio signal as a first signal; (b) restoring, in at least one intermediate layer, a signal obtained by subtracting an upsampled signal, which is obtained by upsampling the audio signal restored in the highest layer or an immediately previous intermediate layer, from the input audio signal as a second signal; and (c) restoring, in a lowest layer, a signal obtained by subtracting an upsampled signal, which is obtained by upsampling the audio signal restored in an intermediate layer immediately before the lowest layer, from the input audio signal as a third signal, wherein the first signal, the second signal, and the third signal are combined to output a final restoration audio signal.

  • Patent number: 8416514
    Abstract: Provided are a lens unit, a lens assembly, a camera module, a method of fabricating the camera module and the lens assembly, a method of fabricating an optic member, and an apparatus of fabricating the optic member. The lens unit comprises a lens portion and a supporting portion. The lens portion has a curved surface. The supporting portion extends from the lens portion. The supporting portion comprises a protrusion or a recess. The method of fabricating the optic member comprises injecting a resin composition inside a mold die, pressing the resin composition; and irradiating light onto the resin composition. Due to the pressure, shrinkage of a photo-curable resin composition can be reduced, and thus, the lens unit comprising the protrusion or recess can be easily fabricated.
