Abstract
A display device and a method of operating the same are disclosed. According to at least one of the various embodiments of the present disclosure, a display device includes a display outputting an input image; and a processor controlling the application of a brightness reduction algorithm to the input image, in which the processor, if calculating the difference in Average Picture Level (APL) values for determining whether to apply the brightness reduction algorithm, may determine whether to update the reference frame based on the difference between APL values of the current frame and the reference frame.
Claims14
A display device comprising:
- a display configured to display input images;
- and
- a processor configured to apply a brightness reduction algorithm to the input images,
- wherein the processor is configured to:
- obtain an Average Picture Level (APL) value of a current frame of the input images;
- obtain a difference between the APL value of the current frame and an APL value of a set reference frame;
- apply the brightness reduction algorithm to the current frame based on the difference being greater than a first threshold;
- updating the reference frame to the current frame based on the difference being greater than a first threshold;
- maintaining the reference frame as the set reference frame based on the difference being less than or equal to the first threshold;
- and
- cause the display to display the current frame having the brightness reduction algorithm applied.
