According to an illustrative embodiment, an apparatus for generating image data is provided. The apparatus includes a communication unit for receiving information related to a display orientation of an image on a display unit of an image display device; and an image generation unit for generating image data according to the information.

Image generation device, program, image display system, and image display device

An AV system composed of an HD recorder and a display unit uses a communication interface of the HDMI. An HDMI source of the HD recorder transmits image data (image signal) in the form of differential signals to an HDMI sink of the display unit through three TMDS channels. The HDMI source inserts content identification information for the identification of the type of a content of image data to be transmitted into an AVI InfoFrame packet placed in a blanking period. A control section of the display unit controls operation of a display processing section which carries out a process for displaying for the image data based on the content identification information received by the HDMI sink and a display section for displaying an image.

Object To transmit well a video signal of a desired bit rate within a transfer bit rate of a transfer path. Solving Means A control unitcontrols the operation of data compression units-through-and switch unit. When the bit rate BR of a non-compressed video signal output from a codecis within the transfer bit rate BRof an HDMI transfer path, the control unitsupplies the non-compressed video signal output from the codecto the HDMI transmitting unitas a video signal to be transmitted. On the other hand, when the bit rate BRis greater than the bit rate BR, the control unitselects a compression method that can be handled on the receiving side performs compression processing so that the bit rate BRbecomes lower than the bit rate BR, and supplies the compression video signal to the HDMI transmitting unitas a video signal to be transmitted. Also, the control unittransmits compression information (control information of the switch unitand data compression units-through-).

Preferred format parameters including timing that is contained in an extended display information data (EDID) EEPROM in a digital video display system can be dynamically established by a user. In this way, when the video display system engages a source of video in a 'plug and play' context, instead of communicating to the source what formats are supported and then accepting a format selected by the source, the preferred format is sent from the EEPROM to the source so that the video display system receives video from the source in the user-desired format.

System and method for dynamically establishing extended display identification data

[Object] To make it possible for the reception side to carry out an optimum process for an image signal (image data) depending upon the type of a content. [Solving Means] An AV systemcomposed of an HD recorderand a display unituses a communication interface of the HDMI. An HDMI sourceof the HD recordertransmits image data (image signal) in the form of differential signals to an HDMI sinkof the display unitthrough three TMDS channels. The HDMI sourceinserts content identification information for the identification of the type of a content of image data to be transmitted into an AVI InfoFrame packet placed in a blanking period. A control sectionof the display unitcontrols operation of a display processing sectionwhich carries out a process for displaying for the image data based on the content identification information (ITC, CTand CT) received by the HDMI sinkand a display sectionfor displaying an image.

There is provided a display device equipped with a display unit, the display device including a receiving part for receiving a difference signal of a plurality of channels including an image signal and content identification information inserted in a blanking period and outputting the image signal and the content identification information; a light emission amount regulation part for setting a reference duty according to image information of the image signal; an adjustment part for adjusting so that an actual duty is within a predetermined range based on the reference duty and an adjustment signal and adjusting a gain of the image signal so that a light emission amount defined by the actual duty and the gain of the image signal becomes the same as the light emission amount defined by the reference duty; and an adjustment signal generation part for generating the adjustment signal based on the content identification information.

Display device, image signal processing method, and program

Correction of electron beam landing misalignment in a raster-type display is undertaken without using the usual set of coils, but rather by superimposing a landing misalignment correction signal on the already-existing velocity modulation (VM) coil or on another coil located at the junction of the electron beams in the neck of the display. The correction signal may be varied based on pressure, temperature, and ambient magnetic field as indicated by respective sensors to appropriately correct electron beam landing on phosphors the positions of which may be affected by variations in magnetic fields, temperature, and pressure.

Active landing control system for raster based devices

A horizontal deflection circuit is provided in which a large retrace pulse voltage applied to a horizontal deflection yoke can be taken to reduce the deflection current and which is capable of easily performing horizontal image size adjustment and distortion adjustment. A parallel connection of a switching element, a damper diode, and a resonance capacitor is connected in series to a parallel connection of another switching element, another damper diode, and another resonance capacitor, and power is supplied from the connection point via a fly-back transformer. The comparison value of the retrace pulse voltages applied across both ends of the switching elements is fed back through a switching element control circuit to the switching element so that the deflection current of the horizontal deflection yoke is controlled.

Horizontal deflection circuit

In a dual direction horizontal bi-directional scan circuit, deterioration of the picture quality is prevented, while linearity is improved without supplying wasteful deflecting current, and pin distortion is corrected. The deflecting current in the going scan and in the returning scan are supplied to each deflecting coil by first and second resonance circuits, and capacitors substantially the same in capacitance are provided in the first and second resonance circuits to bias the deflecting voltage so that the terminal voltage and the power source voltage of the capacitors are synchronized to the vertical synchronizing signals to produce a parabolic modulation.

Bi-directional scan circuit

At a horizontal deflecting circuit of bi-directional deflection, timings of deflection of forward scan path and backward scan path are respectively controlled. The timing of deflection of forward path or backward path is controlled at the first timing control circuit 22 so that it is synchronized with the horizontal synchronizing signal HD and timing of deflection of backward path or forward path is controlled at the second timing control circuit 24 so that deflection cycles of forward path and backward path are equalized. Further, timings of deflection of forward scan path and backward scan path are controlled respectively at first and second phase comparison circuits 22 and 24 so that the relation in phase between the image signal and the deflection takes a constant value on the basis of the horizontal synchronizing signal, to previously prevent occurrence of steady phase error.
