Color sensor insensitive to distance variations

A method for calibrating an image pixel, comprising:

• receiving, by a plurality of color sensing pixels, respective first electromagnetic radiation reflecting from an object;
• generating, by the plurality of color sensing pixels, respective color indicating outputs based on the respective first electromagnetic radiation;
• receiving, by a plurality of distance sensing pixels respectively associated with one or more of the color sensing pixels, respective second electromagnetic radiation reflecting from the object;
• generating, by the plurality of distance sensing pixels, respective distance indicating outputs, a second signal based on the respective second electromagnetic radiation;
• determining, by a device including a processor, respective distances from the respective color sensing pixels to the object based upon the respective distance indicating outputs of the respective distance sensing pixels associated with the respective color sensing pixels;
• and
• calibrating the respective color indicating outputs of the respective color sensing pixels based upon the respective distances from the respective color sensing pixels to the object.
