Camera Memory Allows Rapid Data Transfer

New technology bypasses PC storage.

Dr. Gerhard Holst, PCO AG

In scientific and imaging applications, there is a trend toward CCD and CMOS camera systems with higher spatial resolution and frame rates. Designers have responded to the demand for greater detail and less magnification with more sophisticated cameras — but these come at the cost of data overload. For example, to capture an image of 4008 × 2672 pixels using a camera with 14-bit dynamics, two bytes per pixel are needed for the gray value (if stored as a 16-bit standard tiff image). So the image requires 2 × 4008 × 2672 bytes, or the equivalent of 21 MB of memory. If the image is recorded...Read full article
