Method and apparatus to use array sensors to measure multiple types of data at full resolution of the sensor
An actuator is configured to move a sensor array between first and second positions in order to provide color image data and other data with full resolution of the sensor array. In many embodiments, the output resolution of the sensor array for each type of data comprises twice the resolution of the sensor array without movement. The alternating movement of the sensor array between the first and second positions provides output images with decreased artifacts that might otherwise be present without the alternating movement of the sensor array.
