“Digital technology has been the foundation for advanced camera features since the introduction of digital signal processing (DSP),” says Frank Abram, vice president, Panasonic Security Systems, Secaucus, N.J. “Since the 1980s, Panasonic has introduced cameras with DSP circuitry. DSP technology enables the electronic features found in today’s most advanced cameras.”
“Many cameras do not compensate well for extreme bright and dark areas in the same scene,” says John Ellenberger, senior product manager, Pelco, Clovis, Calif. “Cameras with extended or wide dynamic range analyze the bright and dark sections of the scene, and combine them in a way that provides a picture showing detail in the bright and dark areas.”
