摘要： 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.

摘要： A moving subject detection map is generated by performing moving subject region determination based on input image information from an image capture portion, and is used to set an exposure pattern for a moving subject detected pixel region. The exposure pattern is cyclically arranged with multiple different exposure times. The exposure time for a stationary subject region is set according to the brightness of the subject. Regarding an image captured based on the exposure time control, an output image is generated by computing pixel values for a moving subject region, using pixel value combination processing that utilizes the pixel values of pixels with a plurality of different exposure times being set, and by computing pixel values for the stationary subject region by multiplying a gain according to the exposure time. This achieves the acquisition of a dynamic range image while keeping deterioration of the resolution to a minimum.
