Imaging apparatus, imaging system, and image processing method

An image processing method for processing a pixel signal output from an imaging apparatus,

• the imaging apparatus comprising:
• an imaging device;
• and
• a signal processing unit,
• the imaging device comprising a first pixel and a second pixel each having a photoelectric converter,
• the first pixel is a pixel configured to output a first pixel signal based on a light corresponding to white color on the photoelectric converter,
• the second pixel is a pixel configured to output a second pixel signal based on a light corresponding to any one of colors of green, blue, and red on the photoelectric converter,
• the first pixel is configured to output the first pixel signal in each of a first frame and a second frame, and
• the second pixel is configured to output the second pixel signal in each of the first frame and the second frame,
• the image processing method comprising:
• performing a first inter-frame processing which is an addition of the first pixel signal of the first frame and the first pixel signal of the second frame, and a second inter-frame processing which is an addition of the second pixel signal of the first frame and the second pixel signal of the second frame;
• and
• performing the second inter-frame processing by changing weights of the second pixel signal of the first frame and the second pixel signal of the second frame, based on a difference between the first pixel signal of the first frame and the first pixel signal of the second frame.
