Abstract

In accordance with advances in camera technology, the requirement of high-quality video has greatly increased. Among the factors required for high-quality video are a high-resolution and a high frame rate. However, the limitation of the pixel transfer rate restricts compatibility of a high-resolution and a high frame rate in commercial camera. We propose a dual-sensor camera that consists of two cameras: one with a high-resolution and a low frame rate and the other with a low-resolution and a high frame rate. The system is capable of capturing two different image sequences: high-resolution images and high-frame-rate images. A sensor calibration for the dual-sensor camera is also proposed.
