  • Dynamax-11 CMOS Image Senso
Nov 2011

WOODLAND HILLS, Calif., Nov. 14, 2011 — Panavision Imaging LLC's newly launched 3.2-megapixel CMOS image sensor, the Dynamax-11, offers global shutter technology that improves image quality for indoor and outdoor applied industrial imaging applications.

The technology platform will be the basis for a full CMOS image sensor product portfolio, targeting markets such as machine vision, intelligent traffic systems, security, surveillance, life sciences, scientific imaging, biometrics and high-definition TV (HDTV) camcorders.

The sensor offers ultrahigh frame rates, a wide dynamic range, ultralow noise and either global or rolling shutter operation modes. Proprietary and patented Active Column Sensor (ACS) technology has advantages over CCD and CMOS active pixel sensor technology, the company said.

The imager features a 5-μm pixel, ?-in. optical format with regions of interest in a 16:9 HDTV format. It contains a programmable timing engine offering maximum flexibility with minimal external components. A distributed analog-to-digital converter eliminates gain variations between rows, and the closed-loop feedback of the ACS technology enables high gain per column. The distributed analog-to-digital converter enables variable bit depth from 8 to 12 bits. Flexible high-dynamic-range imaging is achieved by using two data words per row, for dual gain or dual integration data, which can be kept separate on the dual words for proper postprocessing for enhanced image rendering.

Dynamax 11 allows for single- or dual-row readout. Single-row readout is used for the lowest power consumption and dual row, for higher speed and longer line times for dual gain per row or Correlated Multi Sampling (CMS). CMS can be used to further reduce noise, add gain or achieve greater bit depth.

With the four-row readout, which allows 120 fps operation with full resolution, the imager is suitable for applications requiring high speed. It is designed with more than 120-dB dynamic range for outdoor imaging applications.
