Imaging device and signal processing device

A signal processing device for processing a signal output from an image pickup device including a plurality of pixels, the signal processing device comprising

• a calculation unit that performs a first process of subtracting, from a pixel signal of an infrared light pixel that receives light corresponding to an infrared wavelength range, a component based on an inflow amount of charges to the infrared light pixel from other pixel adjacent to the infrared light pixel and a second process of obtaining a signal corresponding to a difference between a pixel signal of a visible light pixel and a pixel signal of the infrared light pixel obtained after the first process.

A signal processing method for processing a signal output from an image pickup device including a plurality of pixels, the signal processing method comprising:

• reducing, from a pixel signal of an infrared light pixel that receives light corresponding to an infrared wavelength range, a component that is included in the pixel signal of the infrared light pixel and is based on an inflow amount of charges to the infrared light pixel from other pixel adjacent to the infrared light pixel;
• and
• obtaining a signal corresponding to a difference between a pixel signal of a visible light pixel and a pixel signal of the infrared light pixel obtained after the component based on the inflow amount of charges to the infrared light pixel from the other pixel is reduced.
