| Abstract(in English) | When taking a photograph of a high dynamic range scene by using narrow dynamic range commercial cameras, we often face the problem of under/over-exposure. It is possible to solve this problem by acquiring High Dynamic Range (HDR) Image. The HDR image is generated by integration of multiple exposure images that are taken with different exposure settings. When taking multiple exposure images for the scene that contains dark areas, we can select one of the three types of the camera settings: (1) camera's sensitivity, (2) exposure time, (3) lens' aperture. Artifacts of high ISO setting and long exposure setting can reduce by denoising and deblurring, respectively. Here, the images taken by setting (3) has out-of-focus problem. Our aim is to address this problem. We generate an all in-focus image without the under/over-exposure and out-of-focus areas due to the wide aperture by integrating the multiple exposure images. We propose a new integration technique for multiple exposure images without the under/over-exposure and defocus. We show the validity of the proposed algorithm by applying it for real scenes and comparing with several conventional methods. |
