Title:
様々な組み合わせのインターレス感光素子を用いた光学位置決めデバイス
Document Type and Number:
Japanese Patent JP2008500662
Kind Code:
A
Abstract:
One embodiment relates to an optical displacement sensor for sensing relative movement between a data input device and a surface by determining displacement of optical features in a succession of frames of the surface. The sensor includes at least a detector, first circuitry, and second circuitry. The detector includes a plurality of photosensitive elements organized in first and second arrays. The first circuitry is configured to combine signals from every Mth element of the first array to generate M group signals, and the second circuitry is configured to combine signals from every M'th element of the second array to generate M' group signals. M and M' are numbers which are different from each other. Other embodiments are also disclosed.
