Color extension and noise reduction method for the smallest module system

Adaptive tone mapping improves the luminance value of the low-light area in an image. A captured image in low light environments has high probability that noise is generated. Therefore, when Luminance of Low-light is enhanced, color noise is increased and also original color tone is changed. This paper proposes color extension and noise reduction method that not uses memories in the event of hardware implementation and can apply to in small module system.
