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 picture processor including a picture-deformation-information input section for inputting the information for the degree of enlargement/contraction of each portion of a picture; a decoding section for inputting encoded picture data of the picture, inputting the information for the degree of enlargement/contraction of each portion of the picture from the picture-deformation-information input section, decoding the picture data every portion of the picture in accordance with the information for the degree of enlargement/contraction, and moreover decoding the whole picture data independently of the information for the degree of enlargement/contraction; a reference picture generation section for generating a reference picture enlarged or contracted for each portion of the picture by using a picture in which the whole picture data is decoded supplied from the decoding section, the information for the degree of enlargement/contraction of each portion of the picture from the picture-deformation-information input section, and the movement vector of the picture data; and an addition section for adding a picture decoded for each portion of the picture supplied from the decoding section and a reference picture supplied from the reference-picture generation section.

Image processor, image data processor and variable length encoder/decoder

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

An apparatus comprises an object generation unit for generating an object based on three-dimensional object data externally input, an object position determination unit that moves the generated object according to a user input, and thereby determines an object position, a view point position determination unit that moves a view point according to the user input and thereby determines a view point position, a distance calculation unit for calculating a distance from the object position and the view point position, a frame rate determination unit for determining a frame rate corresponding to the calculated distance on the basis of a set table or formula, and a frame rate control unit and a moving image generation unit for reproducing the moving image with the frame rate of moving image data externally input reduced.

Device for controlling quality of reproduction of motion picture and method for controlling the same

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

A head-mounted display for displaying an image that matches a viewer's head movement has a head tracker for detecting the viewer's head movement, an eye tracker for detecting the viewer's eye movement, and an adaptive filter for adaptively filtering the output of the head tracker in accordance with the output of the head tracker and the output of the eye tracker, and when tracker, and when the viewer is watching a particular object in the displayed image, the adaptive filter is set as a low-pass filter, and this and the output gain of the head tracker is lowered; in other cases, the adaptive filter is set as an all-pass filter, and this prevents minute shaking of the head from being reflected on the displayed image, while retaining image display response to head motion, and furthermore, this serves to keep the particular object from being shifted outside the field of view.

Head-mounted display

A comb filter separates a luminance signal and chrominance signal from a composite video signal, a phase calculation circuit calculates a phase delay of the chrominance signal, at least one delay circuit delays an output signal of the phase calculation circuit, a phase difference calculation circuit calculates a difference between an output signal of the phase calculation circuit and an output signal of the delay circuit, and a chrominance signal correction circuit attenuates the chrominance signal in response to an output signal of the phase difference calculation circuit. The chrominance signal having crosstalk from the luminance signal is suppressed to prevent the generation of cross color.
