Comparisons of calibrations for still image and movie modes for consumer digital cameras

This paper describes the calibration of five consumer digital cameras in still and movie modes. The cameras tested include a digital SLR, a compact digital still, a digital camcorder and two DV camcorders. The self-calibrations in still and movie modes were conducted sequentially using a single calibration fixture and consistent camera station geometry to minimise the influence of external factors. The variations in image quality are discussed in relation to the image resolution and operation mode. The analysis of the results includes the relationships between the calibration parameters and the measurement precisions for the two modes.
