Imaging apparatus, imaging processing method, and imaging control program |
摘要 |
An imaging apparatus includes: an imaging device outputting, during a unit period of time, a long-exposure-time image signal having a relatively long exposure time and a short-exposure-time image signal having a relatively short exposure time; a first clipping processing mechanism clipping a part not lower than a first signal level of a luminance signal obtained from the long-exposure-time image signal; a second clipping processing mechanism clipping a part not higher than a second signal level of a luminance signal obtained from the short-exposure-time image signal; and a signal processing mechanism generating a synthesized image signal having a dynamic range wider than dynamic ranges of both of the image signals by synthesizing the clipped image signals, wherein the second signal level is not lower than a signal level obtained by dividing the first signal level by a ratio in time of the long exposure time to the short exposure time. |
