Abstract

We investigated the adjustment method of exposure times for multi-exposure image fusion. Because the range of luminance in the natural environment is wide, the camera system need to adapt to the ambient light. The proposed system comprises an image sensor module and a field-programmable gate array (FPGA) which is composed of control circuits for an image sensor, HDR image generator/evaluator and control circuits for external modules. In this study, the exposure time adjustment method is to select the combination with the maximum entropy or the minimum sum of squared difference between equalization histogram to original histogram. As a result, we obtained an image where has high contrast all of area.
