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.

摘要： An image processing device includes an image correction unit which receives a synthesized image and pseudo color pixel information indicating a pseudo color pixel position included in the synthesized image and executes pixel value correction. The image correction unit selects non-pseudo color pixels as reference pixels from a reference region set in a surrounding region of the pixel to be corrected, sets a similarity weight coefficient in which a large weight is set as a pixel value of the reference pixel that is close to a pixel value of the pixel to be corrected and a pixel position weight coefficient in which a large weight is set as the pixel value of the reference pixel that is near a pixel position of the pixel to be corrected, with respect to the reference pixels, and determines a correction pixel value of the pixel to be corrected by a weighted summation process.
