Camera Link Camera

September 1, 2009

The A406k provides 209 frames per second (fps) at full resolution of 2,320 by 1,726 pixels. To achieve its high frame rates, the camera has a complementary metal-oxide semiconductor (CMOS) sensor with a rolling shutter. A flash window provides an output signal when all of the lines in the sensor are ready for exposure, simulating a global shutter. The camera is calibrated and corrected to achieve high image quality. One correction takes care of any deviations in the camera’s 2,352 analog-to-digital converters (ADCs).

The fixed pattern noise (FPN) that is typical for a CMOS sensor also is corrected, as is the photo response non-uniformity (PRNU). The combined result is an image very close to charge-coupled device (CCD) quality, even in a 10-bit mode. The data reading out of the sensor result in up to a 2.4-gigabyte per second data stream.
