    • Long and short exposure time pixel information are input to pixel information. A long exposure time image set with the pixel values assuming all of the pixels have been exposed for a long time and a short exposure time image set with the pixel values assuming all of the pixels have been exposed for a short time are generated. A point spread function corresponding to the long exposure time image is computed as a long exposure time image PSF. A corrected image is generated using the short exposure time image, the long exposure time image, and the long exposure time image PSF. The corrected image is generated as a wide dynamic range image utilizing the pixel information for the long and short exposure time image. Utilizing the pixel information for the short exposure time image with little blurring, makes the corrected image a high quality corrected image with little blurring.
    • 长时间和短曝光时间像素信息被输入到像素信息。 产生具有假设所有像素的像素值的长曝光时间图像已经被长时间曝光,并且产生假定所有像素的像素值设置的短曝光时间图像已经短时间曝光。 与长曝光时间图像对应的点扩散函数被计算为长曝光时间图像PSF。 使用短曝光时间图像,长曝光时间图像和长曝光时间图像PSF生成校正图像。 利用长曝光时间图像和短曝光时间图像的像素信息,生成校正图像作为宽动态范围图像。 利用少量模糊的短曝光时间图像的像素信息,使得校正图像具有很少模糊的高质量校正图像。
