Camera
DXOMARK evaluates the image quality of built-in cameras during video calls across a variety of real-world situations, from professional meetings in an office to personal calls at home. Our testing assesses camera performance under different lighting conditions and during movement, providing a comprehensive understanding of how well devices deliver a clear, natural and consistent video-calling experience.
Other key image quality attributes are also evaluated:
Exposure
Face exposure is a key aspect of the evaluation, assessing the camera’s ability to keep faces clearly visible and well lit, both in stable conditions and when lighting changes during a call.
Color
Does the camera reproduce color accurately? A particular focus is on the skin-tone rendering of the subject. Various skin-tone types are evaluated.
Texture
Does the camera preserve small and fine details in the image, particularly on the subject’s facial features, such as visible freckles or a beard, and the background?
Noise
How much noise is present in the video, particularly in scarce lighting conditions, where the amount of noise can rapidly increase?
Artifacts
Are there any undesirable and unnatural effects appearing on the image, such as distortion?
Autofocus
How well does the camera keep the subject in focus during a video call? The evaluation considers its ability to maintain focus as the subject moves, approaches or moves away from the camera.
The Video Call protocol also examines how well the camera adapts to the natural flow of a conversation, ensuring that the image remains clear and consistent as people move and interact during a call.
