The display unit displays the confirmation image at the image quality settings during calibration.

Calibration device, calibration method and display device

A calibration apparatus including: a measuring unit configured to measure optical characteristics at a measurement position on a screen of an image display apparatus; a storing unit configured to store information on correspondence determined in advance among the optical characteristics at the measurement position and optical characteristics at a plurality of prescribed positions on the screen; an acquiring unit configured to acquire a representative position of an image displayed on the screen; and a calibrating unit configured to perform calibration based on the measurement value measured by the measuring unit, information on the correspondence, and a positional relationship among the plurality of prescribed positions and the representative position.

Calibration apparatus, control method thereof, and image display apparatus

A signal processing apparatus includes an upconversion processing unit upconverting content data stored in a data storage unit, and an upconversion control unit determining an upconversion-target component and the upconversion processing order of components based on component attribute information such as a component type or a tag value of each component of the content data such as elementary streams.

Apparatus and method for upconverting content data

An image analysis unit analysis information appended to an image and calculates the image capture time for each of the images. A time difference calculating unit calculates the image capture time difference between images arranged by an image managing unit by referring to the image capture time for each of the images calculated by the image analysis unit. A user instruction information managing unit sets a threshold that is used in the selection of images to be displayed in one screen and that serves as a determination reference for time differences based on input information of the user. The display determination unit compares an image capture time difference calculated by the time difference calculating unit and a threshold set by the user instruction information managing unit, and selects the images that satisfy this threshold as images to be display in the screen. A display processing unit displays thumbnails of images selected by the display determining unit in an index display in one screen in an image capture time sequence.

Image processing apparatus and control method for image processing apparatus

Additional information indicating photographic conditions for a received image signal is compared with additional information indicating photographic conditions for an access target image signal. If the both conditions satisfy a predetermined relationship, an access to the access target image signal is permitted.

Access control apparatus, access control method, and access control program

A control system includes a control apparatus and a controlled apparatus, wherein the control apparatus is remotely controlled by a remote controller. The controlled apparatus transmits a control panel to the control apparatus. The control panel includes icons used to control the controlled apparatus. The controlled apparatus includes (a) a communication unit which receives, from the control apparatus, remote control information including information about operation keys included in the remote controller, the remote control information being received before the controlled apparatus transmits the control panel to the control apparatus, and (b) a modifying unit which modifies a position of the icons included in the control panel according to the remote control information. The communication unit transmits the control panel to the control apparatus after the modifying unit modifies the position of the icons included in the control panel according to the remote control information.

Data communication system, apparatus and control method therefor

A control unit, after sending information that should be displayed on a sub-display to a sub-control unit, turns power to itself off and enters a standby state. When returning to a power-on state from standby state, first a sub-control unit is started up and a power-on request is made to a main display unit, then, in the interval before completion of start-up of the main control unit, information received from the main control unitwhen it entered standby state is caused to be displayed on the sub-display.

Display apparatus and a control method therefor

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

A receiving apparatus according to the present invention includes a receiving unit for receiving television broadcasts and a communication unit for receiving streaming broadcasts via a network. A guide information producing unit produces guide information for displaying a program guide for television broadcast programs and a program guide for streaming broadcast programs on the same screen. An outputting unit outputs to a display device image data on the television broadcasts, image data on the streaming broadcasts, and the guide information.

Receiving apparatus and receiving method

In a system for viewing accumulated contents by using a cellular phone, if an error prevents the content to be viewed, a simple operation is performed to view the rest at home. In accordance with a viewing request from a cellular phone, a television receiver, while sequentially receiving data from D-VHS, converts the data into a format suitable for reception and play in a cellular phone by using an encoder. After this format conversion, the television receiver stores in a play position memory a time stamp indicating a position information of a content and a sequence number used for transmission in TCP/IP. The cellular phone notifies the television receiver of a decode error of a reception data. When receiving a confirmation response of a normal play from the cellular phone, the television receiver clears the data of the play position memory, and otherwise holds the data of the play position memory.

Television receiver, mobile apparatus, and network information communication system with notification of decode error by turning on decode flag of TCP/IP header

An image control apparatus includes a signal-receiving unit to which image signals are input, a resolution detecting unit configured to detect the resolution of the input image signals, a viewing-distance detecting unit configured to detect a viewing distance between a viewer and a display apparatus, a display-size control unit configured to control a display size of images displayed in the display apparatus, a scaling unit, and an output unit configured to output the images scaled by the scaling unit to the display apparatus. When the resolution of images is changed, the scaling unit scales the image signals in accordance with the amount of change in resolution and the viewing distance, and outputs the signals to the display apparatus.

Display control apparatus and display control method

When the same image is pleasantly viewed by information display apparatuses connected to each other through a network, each of the information display apparatuses has a unit for acquiring display format information of an image displayed by a destination information display apparatus, so that information representing a display format of the image displayed by the destination information display apparatus is displayed on the displayed image in a multiplex mode to make it possible know a viewing state of the destination information display apparatus.
