1. A display apparatus comprising:
- a mirror display;
a sensor;
a storage configured to store transmission characteristics information, and reflection luminance information, of the mirror display;
a processor configured to;
identify a threshold based on the transmission characteristics information, the reflection luminance information, and an amount of external light sensed by the sensor,adjust a luminance of an image signal based on whether a grayscale of the image signal is less than or equal to the threshold, andoutput an image corresponding to the image signal on the mirror display,wherein the processor is further configured to;
based on a grayscale of the image signal being less than or equal to the threshold, increase the luminance of the image signal by a first luminance level based on the reflection luminance of the mirror display, andbased on a grayscale of the image signal being greater than the threshold, increase the luminance of the image signal by a second luminance level based on the reflection luminance of the mirror display.
