Abstract

A dental camera system for creating an image of an object has a dental camera, which comprises a housing and optics arranged therein together with an image sensor. The dental camera system further comprises an evaluation unit which cooperates with the image sensor to capture the object. To achieve a dental camera system whereof the dental camera performs using optics without movable or controllable optical elements, it is provided for the optics to be plenoptic optics which are designed to determine a 4D light field when capturing the object and for the evaluation unit to be designed to calculate at least one representation of the captured object from the 4D light field.
