The present disclosure relates to: an image display device having an EOTF for an HDR image which can maximize the expression or vividness of an HDR image output in the image display device even if the output brightness range according to the hardware performance of the image display device is narrower than the brightness range of the HDR image; and a control method therefor. According to one aspect of the present disclosure, an image display device may be provided, the image display device comprising: a display; a storage unit for storing a plurality of EOTF curves for displaying an HDR content image; and a control unit for causing the content image to be displayed by using EOTF curves, from among the plurality of EOTF curves, corresponding to the maximum output brightness of the display and the maximum content brightness of the content.

Iimage display device and control method therefor using electro-optical transfer function (EOTF) curves for displaying a high dynamic range (HDR) image

The present disclosure relates to an image processing apparatus. The image processing apparatus according to an embodiment of the present disclosure includes a display having a plurality of pixels, and a controller, wherein the controller: calculates an average luminance value of a first frame of an image based on RGB data corresponding to the image; sets a criterion for determining an output level of the plurality of pixels according to the average luminance value of the first frame; controls the display to output a first frame group, including the first frame, according to the set criterion; calculates an average luminance value of a second frame of the image according to a predetermined cycle; resets a criterion for determining the output level of the plurality of pixels according to the average luminance value of the second frame; and controls the display to output a second frame group, including the second frame, according to the reset criterion. Accordingly, by dynamically changing the criteria for determining the output level of the plurality of pixels included in the display based on the luminance value of each frame of the image, the image may be displayed more clearly. Various other embodiments are possible.

Image processing apparatus

The present invention relates to a display device in which, when a pointer reaches an area change detection zone in which a screen is divided into a first area and a second area, a first device receives a control command from a second device so that a first device and a second device having different Oss installed therein can be controlled by one input device such as a display device, a keyboard, and a mouse, and data can be transmitted or received between the first device and the second device.

Display device and control method thereof

A sound apparatus is disclosed. The sound apparatus includes a body, a bracket coupled to a lower portion of a rear surface of the body, a plurality of upper links, one end of each of the upper links being hinge-coupled to the bracket, a middle frame hinge-coupled to the other end of each of the upper links, a plurality of lower links, one end of each of the lower links being hinge-coupled to the middle frame, and at least one speaker module hinge-coupled to the other end of each of the lower links to vertically move according to rotational movement of the upper links and the lower links, wherein a direction of rotation of the upper link is opposite to a direction of rotation of the lower links, and the middle frame moves in a lateral direction during the rotational movement of the upper links and the lower links.

Sound apparatus

An image display apparatus and a method for controlling the same are provided. The method includes displaying at least one of a left-eye object or a right-eye object when the image display apparatus has entered a 3-dimensional (3D) mode, displaying a movement amount object indicating the amount of movement of pixel arrangement of the at least one of the left-eye object or the right-eye object, receiving a pixel arrangement movement amount input through the movement amount object, and changing at least one pixel of the displayed left-eye object to a pixel of the right-eye object and displaying the changed pixel or changing at least one pixel of the displayed right-eye object to a pixel of the left-eye object and displaying the changed pixel according to the pixel arrangement movement amount input. This increases user convenience when stereoscopic images are displayed in an autostereoscopic manner.
