Abstract

We present an embedded software-based automatic calibration system for high-end digital still cameras. By using electronic shutter associated with charge-coupled device (CCD), the system can be used to calibrate the characteristics of the sensor, the mechanical shutter, and the lens accurately. It has been built in several camera models and applied on a practical mass production line. The calibration time for each camera is less than 30 seconds and the calibrated cameras can get very high precision parameters for controlling image capture function.
