Abstract: An image processing apparatus and a control method thereof are provided.

Abstract: An image processing apparatus and a control method thereof are provided.

Abstract: A display apparatus is disclosed. The display apparatus includes an image processor configured to convert a frame rate of an image signal to a frame rate converted image signal, a display configured to display an image based on the frame rate converted image signal, and a controller configured to control the image processor to add an object to at least one of the image signal and the frame rate converted image signal depending on a characteristic of the object.

Abstract: A display apparatus which constitutes a display system configured of a plurality of display apparatuses is provided. The display apparatus includes a communication unit configured to receive screen change parameters in which image information of partial images divided from one image is analyzed from one or more other display apparatuses, and a controller configured to calculate a screen change value using the received screen change parameters and control the communication unit to transmit the calculated screen change value to the one or more other display apparatuses. The image information is screen change information according to change in frames of the divided partial images.

Abstract: A display device includes a plurality of reception units receiving a plurality of content, a storage unit, a plurality of scaler units reducing data sizes of the plurality of content, storing the respective content with the reduced data sizes in the storage unit, and reading the respective content stored in the storage unit according to an output timing, a plurality of frame rate conversion units converting frame rates of the respective read content, and a video output unit combining and displaying the respective content output from the plurality of frame rate conversion units. Accordingly, the resources can be minimized.

Abstract: A control method of a display apparatus having a display panel formed with a plurality of pixels is provided. The method includes: detecting high gray level pixels having gray scale values greater than a predetermined high gray scale value; detecting a highlight zone including the detected high gray level pixels, wherein a gray scale value difference between boundary pixels of the highlight zone and adjacent pixels is greater than a predetermined reference difference; and applying a gray scale value greater than a gray scale value of the high gray level pixels to a surrounding zone adjacent to the highlight zone.

Abstract: An image enhancement apparatus using motion estimation includes: a motion estimation unit estimating a degree of motion between an input image on which image enhancement is performed and a temporally successive image; and an enhancement unit applying the image enhancement to an area without motion in the input image while not applying the image enhancement to an area with motion in the input image on the basis of the motion degree. Accordingly, by performing image enhancement on an area without motion in an input image while not performing image enhancement on an area with motion in the input image, it is possible to prevent image noise from being generated in the area with motion.
