Abstract: An under-display camera is provided, wherein an image acquisition unit including the under-display camera is configured to generate an evaluation image based on a first light, by using an imaging unit including an image sensor. The first light is output by a light emitting unit, including a light source, and passes through a display panel. The under-display camera is controlled based on a result of evaluating a performance of the under-display camera, the result being obtained by calculating a feature value based on the evaluation image, calculating a reference value based on a reference image, and comparing the feature value with the reference value, the reference image being obtained based on a second light output by the light emitting unit, the second light not passing the display panel.
