Provided are a light-emitting diode (LED) display device and a method of operating the LED display device determining whether a line flicker will occur based on a level of an input image signal, obtaining an LED line scan order corresponding to the level of the input image signal and brightness according to the input image signal based on the determining, and driving at least one LED line based on the LED line scan order. An LED line scan order may be adjusted according to a level of an input/output image signal in an LED display device so as to reduce occurrence of a line flicker phenomenon in all levels of the input/output image signal.

Light-emitting diode display device and method of operating the same

A method for detecting a region of interest (ROI) is provided, which includes acquiring a plurality of photographed images by photographing a display apparatus sequentially displaying thereon a plurality of different mono-color images, comparing gray levels of the plurality of photographed images and detecting a target region, and detecting a plurality of corner points of the target region, and detecting the region of interest (ROI) corresponding to a display screen of the display apparatus based on the plurality of corner points.

Apparatus for detecting region of interest and method thereof

A method for controlling a camera for color calibration of multi-displays including: acquiring a first image of data displayed on the multi-displays by photographing the multi-displays with the camera; analyzing color of the data displayed on at least one individual display from among the multi-displays using the acquired first image; determining image capture settings suitable for the color calibration of the multi-displays, based on a result of the analyzing; adjusting the image capture settings of the camera in accordance with the determined image capture settings; acquiring a second image of the data displayed on the multi-displays by photographing the multi-displays with the camera using the adjusted image capture settings of the camera; and performing color calibration of the multi-displays based on the second image.

Method and apparatus for controlling camera for color calibration of multi-displays

A color calibration apparatus includes an image obtaining unit configured to obtain first and second photographed images which are generated by photographing first and second mono-color test images displayed on the display device; a controller configured to detect an ambient light area on which an ambient light is shining within the first photographed image based on pixel values of the first photographed image, and further configured to determine a remaining area of the first photographed image other than the ambient light area as a representative value calculating area; and an image processor configured to calculate a representative value based on pixel values of an area corresponding to the representative value calculating area within the second photographed image, and further configured to perform color calibration of the display device based on the representative value.

Color calibration apparatus and method usable with display device

A display apparatus and a Non-Photorealistic Rendering process (NPR) are provided. The display apparatus includes: an image processor which processes an NPR with respect to an image so that brightness of a pixel having a brightness value less than a predetermined brightness value is reduced and a brightness of a pixel having a brightness value greater than the predetermined brightness value is increased. Accordingly, a cartoon effect can be maximized.

Display apparatus and NPR processing method applied thereto

A liquid crystal display (LCD) apparatus, an LCD driving apparatus, and a method for driving the LCD apparatus are provided. The LCD apparatus includes a panel; and a controlling unit which inserts gray data into at least one pixel included in a pixel group. Accordingly, the stress on a liquid crystal is reduced and thus a residual image is prevented from occurring on a screen.
