Abstract: A processor including: an interface circuit to receive first image data and convert the first image data into second image data; a pattern detecting circuit to detect a pattern in the first or second image data; a brightness detecting circuit to detect a panel brightness value, and to detect a ratio of pixels emitting light; and a real-time sensing circuit, wherein when the pattern is not detected, the real-time sensing circuit performs/stops real-time sensing of the pixels based on whether the panel brightness value is within a range and the ratio of pixels emitting light is greater than or equal to a first threshold; and when the pattern is detected, the real-time sensing circuit performs/stops the real-time sensing of the pixels based on whether the panel brightness value is within the range and the ratio of pixels emitting light is greater than or equal to a second threshold.
