Panasonic’s new high picture quality MOS image sensor has the industry's highest sensitivity
Panasonic’s new high picture quality MOS image sensor has the industry's highest sensitivity.
The company’s new MOS image sensor technologies enable digital cameras, camcorders as well as cameras incorporated in smartphones and other mobile terminals to be slimmer with higher sensitivity and improved picture quality.
By improving the sensitivity of it’s νMaicovicon MOS image sensor and suppressing uneven colour and brightness, which may be an issue for low-profile cameras, Panasonic is ensuring more uniform image quality.
Using these technologies, the company will start mass production of a new MOS image sensor (MN34110) for digital cameras, a diagonal 7.7 mm sensor with 14 megapixel effective resolution, in December 2011 and continue to develop various types.
Current high-sensitivity MOS image sensors suppress unevenness in brightness. CCDs have low colour-mixing characteristics that suppress colour unevenness. The rapidly expanding market for digital cameras with higher image quality and a slimmer body has resulted in greater demand for a stable supply of image sensors that offer both high sensitivity and uniform picture quality.
The new MOS image sensor has the following features:
• The fine process technologies provide a sensitivity of 3050 el/lx/sec/μm2, the industry's highest as a MOS image sensor
• The new light-focusing structure significantly 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 MOS image sensor has been created using the following Panasonic technologies:
• The 32 and 45 nm leading-edge semiconductor process technologies lower the wiring layer profile, expand the opening area, and increase the photo diode volume
• The low colour-mixing characteristics are enhanced by light-focusing structure design technologies that use a three-dimensional wave optics design to minimise light leakage at the structural boundaries
• Image sensor mass-production technologies allow stable production of MOS image sensors with high picture-quality
