This document is an application note about the design guide for digital CCD cameras, which introduces the basics of digital cameras and the features of the Crystal Digital Imaging CCD camera chipset.
This document serves as a design guide for digital CCD cameras utilizing the Crystal AN80 chipset. It explains the transition from analog to digital imaging and how the AN80 supports various camera formats through programmable configuration. The guide details the internal workings of CCD cameras, including light conversion and signal processing.
Digital cameras convert the analog output to digital using an analog-to-digital converter, allowing subsequent image processing to be done digitally.
The two dominant video formats are NTSC and PAL based systems.
The main drawback is that the light gathering capability is relatively small due to the small aperture or opening size.
