Since it is
note
impossible to check
compatibility with all
displays, check the
interoperability before
committing to mass
production.
To reduce
note
image artifacts from
Infrared light, and
provide the best image
quality, OmniVision
recommends an IR cut
filter
OmniVision
note
recommends aCSP
packages use underfill
as part of camera
assembly process.
note
The
OV10640 will be
qualified to AEC-Q100
grade-2 specifications.
