Abstract
A display device is provided. The display device includes a display configured to display at least one of an image and a text; a sensing unit configured to sense ambient illuminance; and a processor configured to gradually increase an output luminance value of the display, if a specific condition is satisfied based on the ambient illuminance sensed by the sensing unit and display attributes.
Claims10
A display device comprising:
- a display;
- a sensor;
- and
- a processor configured to:
- control the display to display a content,
- obtain a display attribute of the content based on an arrangement of objects configuring the content by only using an object having a maximum luminance value among the objects and an object having a next highest luminance value among the objects,
- based on ambient illuminance sensed by the sensor and the display attribute, gradually increase an output luminance value of the display,
- wherein the processor is further configured to gradually increase the output luminance value of the display from a starting luminance value to a targeting luminance value during a luminance variation time, and
- wherein the processor is further configured to variably determine the starting luminance value based on a luminance difference between one object of objects in a frame included in the content and an adjacent object of the one object in the frame.

A control method of a display device, the control method comprising:
- displaying a content,
- sensing ambient illuminance;
- obtaining a display attribute of the content based on an arrangement state of objects configuring the content by only using an object having a maximum luminance value among the objects and an object having a next highest luminance value among the objects;
- and
- based on the sensed ambient illuminance and the display attribute, adjusting an output luminance value of the display in a gradually increased form,
- wherein the adjusting comprises gradually increasing the output luminance value of the display from a starting luminance value to a targeting luminance value during a luminance variation time, and
- wherein the starting luminance value is variably determined based on a luminance difference between one object of objects in a frame included in the content and an adjacent object of the one object in the frame.
