Image quality describes how well a digital camera system performs when reproducing an object or scene. Various characteristics of the camera body (sensor and firmware) and lens contribute different elements to the overall quality of an image.
Image quality, while often thought of as subjective, is also possible to asses using objective measures. These measures are the basis for objective lab testing as well as the development of internationally recognized standards. Objectively testing a camera system requires a proper test lab setup with verifiable test targets as well as control over the environment such as illumination and temperature. When properly analyzed, these image quality elements can indicate where the performance of a digital camera system can be improved.
