of

mechanisms
and
their
operation. The important mechanical features
made way for the electronic ones, thus
changing the very essence of the camera's
design.
As a result, a miniature computer (CPU)
was successfully incorporated in the AE-1 for
the first time in the world to compute, judge,
control, display and regulate required in

Adoption of the Most Advanced Ele
ctronic Technology
The P
l
(Integrated Injection Logic), as
far as its applications in photography are
concerned, is the most outstanding achieve
ment in electronics up to date. An LSI digital
circuit with extremely high properties of
accumulation,
an
operational
amplifier,
a
circuit with full use of an analog switch, a
hyperbolic function resistance using both
thick and thin film technology, an analog-
digital convertor, and the proper interfaces,
together with their construction and arrange
ment in modular form, represent techno
logical breakthroughs that go well beyond the
