Abstract: A display apparatus includes a display, a communication module that communicates with an input device, and a processor. The processor is configured to add pattern information to a first image by changing a pixel value of at least one of a plurality of pixels included in the first image, to display the first image, to which the pattern information is added, on the display, to receive a second image captured by the input device from the input device via the communication module, and to identify input coordinates of the input device or a function to be executed by the display apparatus based on pattern information included in the received second image.

Abstract: An electronic apparatus is provided. The electronic apparatus includes an input comprising input circuitry configured to receive an image and a processor configured to detect a skin area from the image to acquire information on a pixel value of a pixel included in the skin area, to acquire information on characteristics of the skin area based on a face area in the skin area, and to process image quality of the skin area based on the information on the pixel value and the information on the characteristics of the skin area. As a result, it is possible to reduce the image distortion of the skin area occurring when only the analysis of the quantitative elements is performed and to improve the image quality preference of the skin area based on the analysis of the qualitative elements in addition to the quantitative elements.
