Computer mouse for controlling computer monitor display has signal processing circuit receiving signals from 2 parallel image sensors for calculating image shift for controlling scrolling of displayed information

摘要

The computer mouse (40) has one-dimensional image scanner (48) with 2 parallel one-dimensional image sensors (50,52) for scanning an image and providing corresponding image signals, fed to an image signal processing circuit (54) to calculate the image shift and provide signal for the computer (60) that produces corresponding scroll movement of information displayed in a window on the screen (72).
