With a smaller image sensor, a lens designed for a 35mm camera captures only the inner part of the image, cropping off the edges that the sub-size sensor chip can't see.
We'd be surprised if pixel oversampling doesn't make its way into point-and-shoots and eventually even mirrorless and reflex interchangeable lens cameras -- just imagine this technology being combined with a full-size sensor and ultra-fast prime lens.

It differs from its predecessor, the DP1x, because its lens now includes one "F" Low Dispersion glass element to correct aberrations, and its resolution has grown by moving from Foveon's 14.6-megapixel APS-C size image sensor to the 46-megapixel APS-C image sensor found in the company's flagship SLR, the Sigma SD1 Merrill.

The key thing is the size of the sensor, not the millions of pixels on your plate.
With a sensor this size, we were anxious to put the RX1 through its paces in both well-lit outdoor settings and indoor low-light situations.

About 90% of workers at the 50 large and medium-size organizations that have done sensor studies with Dr. Waber's firm agree to don the badges, which are intended to be worn the entire workday. (Bathroom breaks are optional.) Those who opt out can wear a dummy badge, which appears identical but doesn't record or transmit data, he says.
In the past we've seen a tongue-based computer interface or two, the BrainPort sight-via-papillae solution, and this week, at the American Chemical Society's annual meeting, researchers from the University of Illinois at Urbana-Champaign introduced a sensor about the size of a business card that detects and identifies fourteen common sweeteners -- including Splenda, Sugar in the Raw, and Sweet'n'Low.

Consider this: at 1.4 microns this sensor's pixel size is identical to that of the iPhone 4S. This means that pixel for pixel, this shooter matches the competition -- it just uses five times more pixels per image than an 8-megapixel camera.

Researchers implant a small sensor -- about the size of a baby aspirin -- in the motor area of the brain.
The camera's professionalism is somewhat limited by Nikon's DX-format sensor, which is smaller than traditional full-size frames and results in a more limited angle of view.
Featuring the compact size, full-frame, 18 megapixel 24 x 36mm sensor (35mm format), sophisticated image processing and robust construction of the highly successful Leica M9, the M9-P also incorporates features designed for professional users or photographers who prefer a pure, even more unobtrusive styling.

Toshiba implemented back side illumination (BSI) technology and integrated color noise reduction (CNR) to develop its newest CMOS image sensor that fits into an 8.5mm x 8.5mm size camera module and enables high-quality pictures even in low-light conditions.

In his new scheme, each Smart Dust sensor (which Pister calls a "mote") is about the size of a character in this sentence.
That's the case with StickNFind - circular stickers the size of a few 10p pieces stuck together which contain a Bluetooth chip, temperature sensor and battery.
Take the 3D sensor inside the Microsoft Kinect, shrink it down to a tenth of its original size and add a bunch of mobile capabilities, and you have yourself PrimeSense's latest conquest, better known as Capri.
