Abstract: An apparatus for and a method of removing a moire pattern of a digital imaging device are provided. It is determined whether or not a moire pattern is created based on an image frequency of a preview image and a spatial frequency of an image sensor, and when it is determined that a moire pattern is generated, an optical path of light incident to an image sensor is slightly changed to remove the moire pattern. Accordingly, image quality deterioration can be improved, and a problem of unnecessary filtering that causes deterioration of resolution even when there is no moire pattern can be enhanced.

Abstract: An optical connecting module for a hand-held personal computer (HHPC) and a docking station is provided. The optical connecting module includes a first optical module installed in the HHPC, having a first optical device for converting an electrical signal and/or an optical signal into an optical signal and/or an electrical signal, respectively. A second optical module is installed in the docking station and has a second optical device for converting an electrical signal and/or an optical signal into an optical signal and/or an electrical signal, respectively. A coupling unit is provided for slidably coupling the HHPC and the docking station such that coupling sides of the HHPC and the docking station contact each other, thereby aligning the first and second optical devices for optical transmission and reception.
