Cognitive sensor and method of operating of the same

That the sensors and the driving method thereof are provided. It disclosed that the sensor, in response to an external stimulus sensor unit for generating an electric signal; It processes the electrical signal generated by the sensor unit to generate sensed data to an external stimulus signal processing unit; If in the sensing data processing in the signal processor for specifying a region of interest circuitry; And an output unit which outputs the sensed data generated by the signal processing unit; wherein the at least some of the sensed data output from the output section is the sensed data for the region of interest.
