1. A method of analyzing a digital camera, the digital camera comprising an image sensor having a plurality of pixels that generate image data, the method comprising: generating first image data using the image sensor; performing a first analysis on at least one portion of the first image data; generating second image data using the image sensor; performing a second analysis on the at least one portion of the second image data; comparing results of the first analysis to results of the second analysis; generating a first signal indicating a first fault with the digital camera in response to the first analysis differing from the second analysis by a predetermined amount; monitoring control data transmitted to the image sensor; and generating a second signal indicating a second fault with the digital camera in response to the data transmitted to the image sensor not corresponding to data to correct at least one error between an image represented by the first image data and an image represented by the second image data.
