CMOS image sensors are an integral
part of many devices with a digital camera. A main component of the CMOS image
sensor is the pixel array. Each pixel measures the color and intensity of the
light that it receives and transmits that data to the image processing
electronics of the device. The rate at which the image sensor can refresh and
capture a new image, along with the density of pixels, determines what
applications an image sensor can be used for. Typically, the smaller the number
of pixels, the faster an image can be taken in frames per second.

Recently, Teledyne
e2v
released the Snappy 2-megapixel (MP) CMOS image sensor. The new
sensor is specialized for high-speed applications such as barcode scanning and
other 2D scanning purposes. The Snappy 2M features full HD
resolution and a 2.8-μm low-noise global shutter as well as other advanced
features. Unlike other image sensors, CMOS image sensors process their images
on a chip, allowing for advanced noise cancellation, which delivers better
image capture in low-light conditions.

Highly
accurate image sensors are necessary for many applications, such as scanning
barcodes in shipping services, retail sorting, or internet of things
applications. The accuracy of CMOS image sensors in low light and while in
motion is a boon for those applications. Drones and surveillance technology can
also benefit from this technology. The on-chip noise-cancelling provided by
these chips enables a far greater level of detail in low light or otherwise
imperfect conditions.

Key features:

  • Small, low-noise global shutter CMOS pixel (2.8 × 2.8 μm)
  • Small 1/3-inch optical format at full HD format
  • Excellent signal-to-noise ratio at low light
  • HDR modes for wide dynamic scenes
  • Single- and multi-ROI modes for tracking simultaneous
    image regions

Snappy
2M is just the start, and an entire new generation of more accurate and faster
image sensors is on its way for different applications, including reading a barcode
or facial recognition.

“Snappy
2M is the first in a range of innovative sensors specifically aimed at barcode
reading and is designed to empower handheld, mobile, or fixed readers and
automatic identification cameras with better-than-ever performance,” according
to Gareth Powell, marketing manager at Teledyne e2v. “The new sensors feature
our patented Fast-Exposure mode, which ensures that the first image frame is
correctly exposed to enable the fastest possible identification and decoding by
the image processing system, even in diverse or rapidly changing light
conditions.”

The Snappy 2M is a part of a
larger family of sensors that share the same software and hardware
requirements, making it interchangeable and giving options to developers
without forcing them to redesign the architecture of their products, which
could be costly.

Samples and demo kits are available.
