A display apparatus has: a display unit; a light emitting unit for outputting irradiation light; a light detecting unit; an external light intensity specifying unit; and a correcting unit. When the external light intensity is equal to or smaller than an external light determination threshold value and the intensity of light detected by the light detecting unit under irradiating the irradiation light is equal to or smaller than a detected light determination threshold value larger than the external light determination threshold value, an irradiation light intensity is corrected by using a first correcting method. When the external light intensity is larger than the external light determination threshold value or the intensity of light detected by the light detecting unit under irradiating the irradiation light is larger than the detected light determination threshold value, the irradiation light intensity is not corrected or corrected by using a second correcting method.

Display apparatus and irradiation light controlling method

An image display apparatus according to the present invention includes: a light emitting unit configured to include a light source; a display unit configured to display an image on a screen by transmitting light irradiated from the light emitting unit; a detection unit configured to detect light from the light source; and a control unit configured to extend a lighting duration of the light source when the detection unit detects light in a case where the lighting duration of the light source is shorter than a predetermined time length.

Image display apparatus and control method thereof

Some embodiments of the present invention provide a video recording and reproducing apparatus capable of obtaining a video content, recording the video content in a recording unit, and executing an up-converting process on the recorded video content, the video recording and reproducing apparatus comprising a selecting unit configured to select a video content, a retrieving unit configured to retrieve specification information for the video content selected by the selecting unit, and a determining unit configured to determine whether or not to provide a user with a notification that inquires about whether or not to execute an up-converting process on the video content in accordance with the specification information retrieved by the retrieving unit.

Video recording and reproducing 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.

Device control apparatus and device control method in video image display system including a plurality of connected devices

A signal processing apparatus that upconverts a plurality of content data includes an operation unit configured to receive an operation instruction from a user, a generating unit configured to generate user's preference information based on an operation history corresponding to the operation instruction received by the operation unit, a processing unit configured to upconvert the plurality of content data, and a control unit configured to calculate a preference level of each content data to preferentially upconvert content data having a high preference level based on the preference information generated by the generating unit and content information about each content data.
