  • Publication number: 20110187870
    Abstract: The present invention discloses a video/audio module applied to a computer system. The video/audio module includes a circuit board, at least one analog microphone unit, and at least one analog-to-digital converter. The analog microphone unit and the analog-to-digital converter are electrically connected and fixed to the circuit board. The analog microphone unit captures an audio signal from ambient air and converts it to an analog audio signal. The analog-to-digital converter receives the analog audio signal and transforms the analog audio signal into a digital audio signal. Because of the analog-to-digital converter, a digital microphone unit can be replaced by the analog microphone unit, thereby reducing the production cost of the video/audio module.

  • Publication number: 20070092138
    Abstract: An image correction method is provided. First, scan an all-white document and form a scanned image including a plurality of image pixels with each of them having a gray level value. Next, gather these gray level values statistically such that each of them has an image pixel quantity. Then the maximum gray level value and the minimum gray level value are selected and a middle gray level value is obtained accordingly. Following that, determine whether the reference gray level value is greater or smaller than the middle gray level value according to the document, select the gray level values from within the interval of (the reference gray level value ± a gray level value), and weight average the selected gray level values according to these selected gray level values and their corresponding image pixel quantities to obtain a corrected gray level value.
