Teledyne e2v announces a 5MP CMOS image sensor that enables fast, extended range image scanning

To meet the increasing demand for CMOS image sensors for a variety of high-speed scanning and embedded vision applications, Teledyne e2v has added a new 5 Megapixel device to its Snappy image sensors. The new Snappy 5M addresses the emerging requirements of barcode reading, 2D scanning and other applications.

Available in both monochrome and color, the sensor 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.

Key specs of Teledyne’s new 5MP image sensor

The new sensor 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.

MCUs Add Extra Features

According to the announcement, 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.

The Snappy sensors enable a number of applications including embedded industrial imaging systems, drones, IoT edge devices, intelligent surveillance cameras and augmented reality/virtual reality.
