 The main parts of a [[intro_cmos|CMOS]] image sensor are the following: The main parts of a [[intro_cmos|CMOS]] image sensor are the following:
  
-* Sensor chip (wafer, node = 40-180nm): An array of photosensitive pixels, with Bayer pattern +* Microlens : Focus the light and direct it to the photodiode 
-* Wire bonds +* Color filter : Designate light colors 
-* Package +* Photodiode : Absorbs the light and converts it into an electrical charge 
-* Cover glass +* Transisors : Control the signal flow and processing 
-* Contact pads+* Package : Protect the chip and provide connections to the electronics that will use the image.

-Exclusion of other sensors like the distance sensor to adjust the focus. +Exclusion of other sensors such as Photoelectric sensors, Active ranging sensor modules, Infrared sensors, etc.
-Exclusion of the rest of the image-processing system (PCB, controllers, etc.).+
  
-Exclusion of laser sensor and IR sensors. Not the focus for now+Exclusion of the component for the image-processing system (PCB, controllers, etc.).
