  • Publication number: 20130194482
    Abstract: An image sensor is formed by a pixel array and a microlens array. One microlens is associated with each pixel. The microlens is positioned in a manner that is offset from a center of its associated pixel. The positioning offset for the microlens is a combination of a first offset determined as a function of the pixel's position relative to a center of the image sensor and a second offset that is randomly selected (both in terms of distance and radial direction). The random offset provides the effect that the spatial frequency information from the shifted microlens array is randomly distributed so as to provide different spatial frequencies and effectively cancel out Moiré interference.

    Abstract: A method of operating a speaker system including a speaker coupled to an amplifier, and a dedicated digital speaker protection circuit includes turning on the amplifier in a mute mode, after a first delay period, issuing a play command to the amplifier to place the amplifier in a play mode, but without an input signal during a second delay period, and performing a speaker offset detection during the second delay period, wherein, if there is an offset, then the amplifier is forced back into the mute mode, and if there is no offset, then the amplifier is allowed to continue to operate in the play mode. The method also includes issuing a speaker protection control signal or command if an offset is detected.
