An image processing device is comprised of a parameter storing unit (i) storing a plurality of inverse gamma correction parameters, color conversion parameters, gamma correction parameters and the like, and (ii) selecting one parameter from each of a plurality of such parameters according to an inputted image signal. Further, the image processing device includes an image signal processing unit performing image signal processes such as inverse gamma correction, color conversion, gamma correction and the like, on the basis of the parameters selected by the parameter storing unit.

Image processing device

An image processing support system has an image processing support device that includes a parameter calculating unit for calculating parameters on the basis of results of measurements made by a measuring device and target values notified by a target setting unit. The image processing support system also has an image processing device that includes an image signal processing unit for performing image signal processing such as inverse gamma correction, color conversion, and gamma correction on the basis of the parameters which are an inverse gamma correction parameter, a color conversion parameter, and an gamma correction parameter stored in a parameter storing unit. Further, the image processing support system has a display device for displaying an image signal.

A coordinate light source calculating unit calculates 3D coordinates for points forming one or more objects and performs clipping. A rendering unit performs rendering and outputs the formed CG image to a frame buffer . The coordinate light source calculating unit calculates 3D coordinates forming a video display surface. A perspective projection unit calculates 2D coordinates for each point forming the video display surface. An image decoder decodes a video frame, and an image transform unit transforms this image and outputs it to the frame buffer , enabling the video frame to be pasted onto the CG image.

Moving image combining apparatus combining computer graphic image and at least one video sequence composed of a plurality of video frames

A storage unit stores image data for a window, and a three-dimensional position calculating unit calculates a position for the window in a virtual three-dimensional space so that it appears to be at a position inclined in the depth direction. A perspective projection unit transforms image data so that a window positioned at the calculated coordinates is projected onto a screen in perspective, taking a point in front of the screen as a viewpoint. A frame memory unit holds image data for the window on which perspective projection has been performed, and a display unit displays the window on the screen.

Window display device with a three-dimensional orientation of windows

A broadcasting reception apparatus includes a display unit for presenting a display showing a plurality of channels, with which the user can recognize whether decoding software programs for decoding program signals being currently broadcast via each channel are held in a library buffer, or not, thereby making possible pleasant zapping.

Broadcasting reception apparatus and data broadcasting method

It is an object of this invention to provide a graphic display apparatus that reduces the amount of CG data transferred from a server through a network and that allows three-dimensional characters displayed at a terminal to move smoothly. It is another object of this invention to provide an AV synchronous reproduction apparatus that can synchronize an image with a score the tempo of which is changed during reproduction. According to this invention, when a server instructs a terminal to graphically display three-dimensional characters, the terminal provides a plurality of motion patterns. The server then transmits scenario data to the terminal, and the terminal operates based on the scenario data to switch scenes for graphical displays. The terminal switches the scenes for graphical displays with a timing for a home position which is common or substantially common to a motion pattern being executed and a motion pattern to be executed next.
