Wide-dynamic-range imaging using variable-integration-time image sensor controlled by FPGA
Details
Conventional image sensors have narrow dynamic range in comparison to human vision. This causes image degradation by over exposure or under exposure. For that reason, vehicle mounted camera or surveillance camera requires wide dynamic range image sensors. But it is required to adjust the tone range to the display so as to render the image suitably. We propose a method for controlling variable integration time image sensor in real time in this paper. Also we describe the result of controlling by FPGA on which the proposed method is implemented.
