Abstract
Provided is an imaging device including an image sensor for outputting a high-sensitivity pixel signal from a long-time exposure pixel and a low-sensitivity pixel signal from a short-time exposure pixel; and a blooming correction processing unit for receiving the output pixel signal from the image sensor and executing blooming correction for the pixel signal. The blooming correction processing unit executes pixel value correction of the input pixel from the image sensor according to a difference between or a ratio of an input pixel value from the image sensor and an ideal pixel value not affected by blooming.
