Abstract: The present invention aims to simplify stitching algorithm which generates horizontal panoramic image. The image pickup device of the present invention comprises a plurality of lenses and positioning means. Said positioning means positions each lens so that the FOV (Field Of View) intersection points of all lenses are aligned in vertical direction. Accordingly, the horizontal parallax does not exist in the image picked up by the camera system and the stitching point remains the same for the objects at different distances.

Abstract: A system and method of high speed clock/data recovery, which is used to recover the high speed clock/data through oversampling technique, wherein the internal clock with frequency lower than the high speed data is used for data recovery. Only three clocks are used in the digital circuit without involving all the oversampling clock phases to make the design timing complicated and critical. The system and method provide a simple clock structure to implement the digital circuit of high speed clock/data recovery in a robust and easy way. Furthermore a phase selection mechanism which decides the clock phase of the high speed data is provided as well.
