摘要： Provided is an image processing apparatus including an image signal correction section that performs an image correction process. The image signal correction section performs a direction determination process of detecting a direction having a minimum pixel value gradient as a pixel value gradient direction in a pixel area including a target pixel; a defect detection process of calculating a Laplacian based on a pixel value of a reference pixel in a minimum gradient direction detected in the direction determination process with respect to the target pixel, and determining presence or absence of a defect of the target pixel; and a defect correction process of performing calculation of a corrected pixel value, which is obtained by applying the pixel value of the reference pixel in the direction detected in the direction determination process, with respect to a target pixel from which a defect has been detected in the defect detection process.

摘要： 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.
