We present a new artifact-free HDRI technology for a consumer digital camera that is based on de-ghosting with a dual-brightness mapping. The proposed approach reduces motion artifacts and the number of capturing images.

Moving object-High Dynamic Range Imaging (HDRI) for artifact-free digital camera

Active Motion High Dynamic Range Imaging (HDRI) is a new artifact-free HDRI technology for a consumer digital still camera. This technology allows us to optimize capturing time and to remove motion artifacts by a camera motion and a moving object. To optimize the capturing time, the key component of our approach is a dual-brightness mapping to detect and compensate the artifacts with just two images. This paper shows that the proposed HDRI approach effectively corrects the artifacts.

Active Motion High Dynamic Range Imaging for digital still camera

Film photographers had used to "dodge and burn" to express a greater dynamic range than original photographic paper. The greater dynamic range imaging is a big challenge on general digital camera area. In this paper, we propose a solution to generate a high dynamic range (HDR) image on a digital still camera, considering a minimum resource and a variable dynamic range capturing. Our approach consists of three parts: scene capturing, HDR image generation and DR compression. The scene capturing needs an adaptive controlling of the exposure time during multiple captures. The HDR image generation from multiple captured images has to preserve and combine the captured dynamic range data for storage and display having low dynamic range (LDR). Our research is implemented onto a commercialized camera system and is evaluated by the maximum capturing dynamic range and the HDR image quality
