Image sensor from Panasonic captures uneven
brightness and color
Panasonic Corporation has developed Maicovicon 2 MOS image
sensor which can capture unevenness in brightness and color
offering both high sensitivity and uniform picture quality.
Panasonic says it has achieved both MOS image sensor's
high sensitivity and uniform picture quality using the new
MOS image sensor technologies, enabling digital cameras
and camcorders as well as cameras incorporated in smartphones
and other mobile terminals to be slimmer with higher sensitivity
and improved picture quality.
The new MOS image sensor has the following features:
The fine process technologies provide a sensitivity of 3050
el/lx/sec/µm2 (Panasonic claims this is the industry's
highest as a MOS image sensor).
The new light-focusing structure expands the incident light
angle, ensuring uniform and high picture quality, as well
as produces a slimmer camera.
The simple manufacturing process is based on the current
MOS image sensor structure, ensuring a stable supply.
The new MOS image sensor has been created using the following
Panasonic technologies:
The 32 and 45 nm (nanometers) semiconductor process technologies
lower the wiring layer profile, expand the opening area,
and increase the photo diode volume.
The low color-mixing characteristics are enhanced by light-focusing
structure design technologies that use a three-dimensional
wave optics design to minimize light leakage at the structural
boundaries.
Image sensor mass-production technologies allow stable production
of MOS image sensors with high picture-quality.
