An image display device including: a light-emitting unit that is capable of individually controlling emission amounts in each of a plurality of regions constituting a screen; a display unit that displays an image on the screen; and a control unit that sets a first region in which display is performed at a predetermined brightness and a second region in which an image is displayed at a lower brightness than the predetermined brightness in the screen, wherein the control unit sets the second region in a region excluding the first region in the screen on the basis of an influence of light leakage from the first region.

Image display device and control method thereof

The present invention resides in an image display apparatus for displaying an image on the basis of image data; the image display apparatus comprising light emitting unit having a plurality of light sources for performing light emission that can be independently controlled respectively; setting unit which sets light emission control blocks for controlling one light source or the plurality of light sources with a common brightness; brightness determining unit which determines the light emission brightness of each of the light emission control blocks on the basis of the image data; and control unit which controls the light emission of the light emitting unit for each of the light emission control blocks in accordance with the light emission brightness determined by the determining unit; wherein the setting unit sets a size of the light emission control block of the light emitting unit depending on an amount of motion of the image.

Image display apparatus and method for controlling the same

In a television device (audio output device), audio output performance information of the television device is pre-stored in an EDID-ROM. When an AV amplifier is connected to the television device, a control unit rewrites '2ch' audio output performance information of the television device stored in the EDID-ROM of an HDMI port which is different from the HDMI port to which the AV amplifier is connected, to '5.1ch' audio output performance information of the AV amplifier.

Audio output device connectable with plurality of devices and method of controlling the same

When a video output apparatus () is connected, a video display apparatus () obtains information of content data stored in the video output apparatus (). Then, based on the obtained information, the video display apparatus () determines whether the content data is decodable with respect to itself. If it is not decodable, it requests the video output apparatus () to decode the content data before transferring the content data using a data transfer method specified. By doing this, an appropriate transfer protocol is selected automatically when transferring content data between the video display apparatus () and the video output apparatus ().

Video display apparatus and control method thereof, and video output apparatus and control method thereof

When an image processing apparatus capable of connecting to a digital camera is to perform image-correction processing on irreversible-compression encoded image data acquired from the digital camera, it is determined whether the image-correction processing can be executed by the connected digital camera. When the processing can be executed, it is confirmed whether or not RAW data that corresponds to the irreversible-compression encoded image data is present in the digital camera. If the corresponding RAW data is present in the digital camera, the digital camera is requested to execute the image-correction processing based on the RAW data. This makes it possible to suppress degradation in the image quality more than when directly correcting an irreversible-compression encoded image.

Image processing apparatus and control method thereof

A device control apparatus in a video image display system including a plurality of connected devices. The apparatus includes an obtaining unit which obtains a logical address of a first device connected to the device control apparatus as a control object, a specifying unit which specifies the device type of the first device if the obtained logical address of the first device is not a logical address according to the device type, a selection unit which selects a second device which is connected to the device control apparatus and is of the same device type as the first device, and a control unit which controls a logical address assigned to the selected second device according to the device type thereof so that the first device obtains a logical address.
