Abstract
An imaging device includes an image pickup device having pixels and a correction processing unit that corrects signals output from the image pickup device, the pixels include a visible light pixel that receives light corresponding to a visible light wavelength range and an infrared light pixel that is arranged adjacent to the visible light pixel and receives light corresponding to an infrared wavelength range, and the correction processing unit includes a calculation unit that performs a first process of reducing, from a signal of the infrared light pixel, a component in the pixel signal of the infrared light pixel and based on an inflow amount of charges to the infrared light pixel from another pixel adjacent to the infrared light pixel and a second process of obtaining a signal corresponding to a difference between pixel signals of the visible light pixel and the infrared light pixel after the first process.
