Abstract: Methods of adjusting an image sensor may be provided. A test image of a test chart including an evaluation area may be obtained using the image sensor. The evaluation area may have a shape of a circle, wherein the evaluation area includes first through nth unit areas arranged in a rotational direction around the circle, and wherein each of the first through nth unit areas has a different level of brightness. A signal-to-noise ratio (SNR) may be calculated for each of the first through nth unit areas based on the test image of the test chart. A setting of the image sensor may be adjusted based on calculating the signal-to-noise ratio for each of the first through nth unit areas.
