5-MP CMOS Image Sensor for High-Speed Scanning & Embedded Vision Applications

Posted Nov 02, 2018 by Teledyne e2v

Teledyne e2V has released a new 5 Megapixel device in its Snappy family of image sensors. The Snappy 5M is designed for barcode reading, 2D scanning and other demanding applications. Available in both monochrome and color, it has a small 1/1.8 inch optical format, containing a 2.8μm, low-noise, global shutter pixel, and arranged in a 2,560 x 1,936 array. The device can stream video at ~50fps at 10 bits over a 4 wire, MIPI CSI-2 interface, and is housed in a small compact fan-out organic package.

Snappy 5M is designed to enable fast, extended range scanning and includes powerful unique patented features and region of interest modes:

  • A Fast Self Exposure (FSE) mode automatically calculates the optimum integration time that is applied to the first image from the device. The mode is user programmable and provides continuous fast decoding, tolerating any kind of lighting or dynamic lighting environment. This is advantageous compared with conventional auto exposure methods, improving convergence speed and robustness.
  • A Smart ROI feature searches for barcodes in the image frame, and reports their locations as metadata in the image footer. The regions of the image containing barcodes are discerned from the background image to considerably reduce downstream image processing (FPGA/CPU/DSP) power, time and cost. Up to 16 different regions can be detected simultaneously. Other forms of repetitive signatures such as printed character strings can also be detected for document scanning and OCR applications.

The Snappy family of sensors enable a number of applications including embedded industrial imaging systems, drones/UAVs, IoT edge devices, intelligent surveillance cameras and augmented reality/virtual reality. The sensors have identical software and hardware requirements, which bring further cost savings by enabling a complete range of scanners/cameras at different resolutions from a single system design effort.

Samples and demo kits will be available in January 2019. Teledyne will be showcasing the new offering at the upcoming VISION 2018 event in Stuttgart from 6-8 November.
