Abstract:
In this paper, we propose a novel imaging method called variable exposure time imaging for obtaining HDR
images from single image capture. In this method, we control exposure time pixel by pixel. Thus, each pixel
in an image taken by this imaging method is obtained under different exposure time. We call this image
variable exposure image. By using the variable exposure image, we can synthesize a high dynamic range
image efficiently, since we can optimize the exposure time pixel by pixel according to the input intensity
at each pixel. Experimental results from the proposed method show the efficiency of the proposed imaging
method.
