ATLab
developed optical navigation
algorithm second in the
world. Its optical mouse
sensor provides various
functions for optical
mice to guarantee optimal
operating environment
during office work, web
surfing or gaming. It
is able to find the track
of the mouse very accurately
by complete 2D motion
sensing technology, one
of logical search engines.
2D
motion sensing technology,
ATLab¡¯s proprietary motion
detection technology,
consists of Image Acquisition
System (IAS) reading images
from the surface reflecting
light, ADC converting
images from IAS to logical
signals and Motion Vector
Finder (MVF) calculating
magnitude and direction
with mouse movement. Therefore,
this 2D motion sensing
technology enables to
find motion perfectly
even if users move the
mouse in fast speed.
The
key characteristic in
ATLab¡¯s optical mouse
sensor is to be designed
by system level architecture
hence it integrates lots
of components within a
chip for complete mouse
functionality. For example,
SoC devices such as PS/2
1-chip device or USB,
PS/2 combo device which
include MCU within a chip
don¡¯t need external processors
for the connection with
PC, which will reduce
BOM and design complexity.
