CMOS Image Sensor Ogles Embedded Vision Space

Teledyne e2v enriches its Snappy family of image sensors with a 5-Mpixel device. The Snappy 5M is designed for barcode reading, 2D scanning, and other demanding applications. Available in both monochrome and color, it has a 1/1.8-inch optical format, containing a 2.8-μm, low-noise, global shutter pixel, and arranged in a 2,560 x 1,936 array. The device can stream video at 50 fps at 10 bits over a 4-wire, MIPI CSI-2 interface, and is housed in a small compact fan-out organic package.

 

Features include: 

  • 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.  

Samples and demo kits will be available in January 2019. For more information, visit Teledyne Imaging.
