Light-emitting apparatus and display apparatus

An image display apparatus according to the present invention includes: a light-emitting unit capable of separately controlling the emission brightness in each of a plurality of divided regions in a screen; a determining unit configured to determine a target brightness of a predetermined divided region, based on image data corresponding to the predetermined divided region; an estimating unit configured to estimate the brightness of the predetermined divided region when light is emitted by the light-emitting unit at emission brightness which is based on image data in each of the plurality of divided regions; and a control unit configured to control the emission brightness of two or more divided regions including the predetermined divided region based on the difference between the target brightness determined by the determining unit and the brightness estimated by the estimating unit.

Image display apparatus and control method thereof

The backlight device is configured in a planar geometry by the combination of a plurality of light emitting units. The light guide plate of the light emitting unit has a light guide unit that guides light from the light source and a light emission surface that emits light from the light guide unit. Adjacent light emitting units are arranged to cross to each other and the light emission surface of a light emitting unit overlaps with the light guide unit of another light emitting unit such that the light guide unit of each light guide plate of the light emitting unit does not extend outside the light emission region of the backlight device.

Backlight device and display apparatus

A picture control device configured to convert and output a bit-rate of an input picture data stream having an input bit-rate, includes: a first decoder configured to decode the input picture data stream; an encoder configured to encode the output of the first decoder with a plurality of converted bit-rates; an output unit configured to output the picture data encoded with a first bit-rate by the encoder, for recording; a second decoder configured to decode the same picture data encoded at a second bit-rate by the encoder; and a control unit configured to determine the second bit-rate based on the first bit-rate.

Picture control device and method of the same

Conversion information regarding a method of frame-rate conversion executed in an image pickup apparatus is attached to video data, and the video data with the attached conversion information is passed to a playback apparatus. In the playback apparatus, an optimal image processing method is selected according to the conversion information.

Apparatuses and methods for processing video signals

When a communication between a camera and a television is performed utilizing a first wireless communication mode which employs high-directional radio transmission, and a second wireless communication mode which employs low-directional radio transmission with lower directivity than that of high-directional radio transmission, the television detects that the communication in the first wireless communication mode has been disconnected and notifies the camera. The camera determines whether or not the movement of the camera is the cause of disconnection in the first wireless communication mode. If the reason for disconnection is the movement of the camera, a control signal is transmitted to the television so as not to execute the process for an avoiding no-signal condition.

Transmission apparatus, method for controlling transmission apparatus, and information communication system

There is provided a video output apparatus which inputs a video content that can have at least three different resolutions. A format detector detects an alteration of a resolution of a video content. A scaling processor scales up the video content at a set scale ratio. Upon detection of an alteration of the resolution, the format detector selects one of a plurality of supplemental video pictures, which are prepared in advance in a memory, in accordance with the degree of decrease of the resolution after the alteration to that before the alteration. An image composition unit controls a display unit to display the supplemental video picture together with a video associated with the video content via a video display unit.

Video output apparatus and control method thereof

The present invention provides a data storage device comprising a disk storage medium containing user data in a plurality of sectors, a head for writing or reading the user data and error correcting means for correcting an error that occurs in the user data during the reading process. The error correcting means comprises a syndrome generator for generating syndromes on the basis of the user data contained in predetermined sectors, registers for storing the syndromes generated and an exclusive OR circuit for exclusive ORing the values stored in the registers.

Error correction method and apparatus for data storage device

A data storage device comprising a disk storage medium containing user data in a plurality of sectors wherein each of the plurality of sectors comprises a subdivision of a track, a head for writing or reading the user data and error correcting means for correcting an error that occurs in the user data during the reading process. The error correcting means comprises a syndrome generator for generating syndromes on the basis of the user data, a Euclid circuit, a chien search circuit and a verification circuit, and makes the error correction using a first error correcting code appended to each of a plurality of sectors and a second error correcting code appended to said sector for every block composed of a predetermined number of sectors.

Data storage method and data storage device

Embodiments of the invention provide techniques to inspect the track pitch of a magnetic disk. In one embodiment, the track pitch is inspected using the servo information that was written onto the magnetic disk. A PES gain is set to be PGA head is moved to a position K near the position where control is to switch between MPES and SPES, and then MPES and SPES are calculated using reproduced burst signals and PGThe quantity of change in the inspection HSP which is a half-servo pitch of an inspection-related burst pattern, with respect to an ideal half-servo pitch, is detected by calculating PES&#x394;, the difference between the MPES and SPES at position K. The track pitch is thus judged whether it is abnormal.

Method for inspecting track pitch in a magnetic disk

The exclusive OR (XOR) of user data (sector), user data (sector)and user data (sector)is taken to have the virtual user data, thereby giving rise to a correlation of the sectorsto, and its virtual user data is appended with Chaving a greater error correction capability than C, whereby an error uncorrectable with Cis correctable with C
