Problems solved by technology

In such a case, the gaze cannot be concentrated due to the unnatural difference in three-dimensionality, and as a result, the sense of presence is reduced.

no. 2 Embodiment approach

[0497] In the first embodiment, the plane shift is realized by shifting the contents of the storage elements in the plane memory. This plane shift improvement is achieved when part 15 is in place. Here, one line among sets of pixel data having a resolution of 1920×1080 or 1280×720, that is, a set of 1920 pixels in width or a set of 1280 pixels in width is called line data. Furthermore, the compositing unit 15 composites the line data read out from the video plane, the background plane 11 , the image plane 8 , and the interactive graphics plane 10 respectively.

[0498] Figure 39 It is a figure which shows the structure of the combining part 15. As shown in this figure, the synthesis unit 15 is composed of line memories 50 to 54, an α1 multiplication unit 54, a (1-α1) multiplication unit 55, a mixing unit 56, a (1-α2) multiplication unit 57, a scaler 58, and an α2 multiplication unit. 59. A mixing unit 60 , a scaler 61 , an α3 multiplication unit 62 , a (1−α3) multiplicatio...

Abstract

Disclosed is a playback device that provides stereopsis by outputting each of a plurality of video frames stored in a video plane as a right-view video frame and a left-view video frame. A graphics plane stores image data with resolutions of 1920x1080 and 1280x720 as graphics data, and a shift engine shifts the coordinates of each item of image data in the graphics plane in either the right or left directions to execute left-view output while also shifting the coordinates of each item of image data in the graphics plane in the direction opposite from the left view to execute right-view output.

Description

technical field [0001] The present invention belongs to the technical field of graphic synthesis technology. Background technique [0002] The so-called graphics synthesis technology is a technology for superimposing and displaying graphics representing subtitles and GUIs on each video frame constituting a video stream. As a technical trend of display devices used for such displays, stereoscopic displays that allow viewing not only flat images but also jumping-out images have begun to spread. There are various types of stereoscopic displays, but as a basic principle, a mechanism for seeing different images from the left view and the right view is introduced, and by using the parallax between the two eyes, a three-dimensional video is simulated. [0003] If the viewer wants to watch the three-dimensional image at the same frame rate as the normal two-dimensional image, the display side needs twice the normal response performance, for example, in order to display a video of 6...
