A Two Million Frames Per Second 300kpixel Single Chip Ultra-high-speed Color Camera with Dynamic Range Compensation for Broadcast Use

Abstract

We successfully developed a two million fps 300kpixel single chip ultra-high-speed color camera with dynamic range compensation. To reduce the drop in the dynamic range, which is dependent on frame rate, dynamic range compensation was developed, which improved the dynamic range at a frame rate of over 700,000 fps. The ultra-high-speed color camera with an ultra-high-speed CCD V6 with Bayer color filter and a driving circuit with dynamic range compensation was developed. In the experiment, a dynamic range of 41.5dB was measured at a frame rate of two million fps, which was an improvement of 4.7dB compared to using the camera without dynamic range compensation.
