Help on creating a dual camera module

I'm interested in using Arduino to create a device that will compare the color of two different area(is one darker than the other), using two different cameras(?) and creating a motor output. Is this possible with an Arduino board?

Is it possible? Absolutely. Is it possible using camera modules.... not so much. You can buy color sensors and have the two compare their input values for the colors they are sensing. Then you can set an output to a motor. Can you explain more about what this project is? such as what board you have, what motor etc...
