Image display method and device for multi-view stereoscopic display
View Patent ↗A multi-view stereoscopic display includes multiple viewing areas periodically disposed along a horizontal direction, and each of the multiple viewing areas includes multiple viewpoints. The method comprises obtaining a position of a viewer, determining that if the viewer is located in an inversion region, and if the position of the viewer is located in the inversion region, executing a preset process for left and right eye viewpoint images of the viewpoints respectively corresponding to the viewer's left eye and right eyes so as to decrease the brightness contrast of the left eye and the right eye viewpoint images in order to reduce the discomfort of the viewer for watching in the inversion region and adding the comfort of watching the stereoscopic image.
1. An image display method for a multi-view stereoscopic display, wherein,
the multi-view stereoscopic display includes multiple viewing areas periodically disposed along a horizontal direction; each of the multiple viewing areas includes multiple viewpoints and the number of the multiple viewpoints is the same in the each viewing area, the method comprising:
obtaining a position of a viewer;
determining that the viewer is positioned in an inversion
region, wherein, the inversion region is the position of the viewer that the viewpoint corresponding to the viewer's left eye and the viewpoint corresponding to the viewer's right eye are respectively located in the adjacent viewing areas; and
for the viewer that is positioned in the inversion region, executing a preset processing for a left eye viewpoint image of the viewpoint corresponding to the viewer's left eye and a right eye viewpoint image of the viewpoint corresponding to the viewer's right eye so as to decrease a brightness contrast of the left eye viewpoint image and the right eye viewpoint image;
wherein, the viewpoints in each viewing area are sequentially assigned a serial number; and the step of executing a preset processing for a left eye viewpoint image of the viewpoint corresponding to the viewer's left eye and a right eye viewpoint image of the viewpoint corresponding to the viewer's right eye comprises:
(a) respectively obtaining series numbers of the viewing points corresponding to viewer's left eye and right eye, and averaging the two series numbers as a serial number of a middle viewpoint;
(b) respectively decreasing brightness values of the left eye viewpoint image and the right eye viewpoint image by a preset ratio; and
(c) compensating the brightness values of the left eye viewpoint image and the right eye viewpoint image with the preset ratio of a brightness value of a middle viewpoint image corresponding to the serial number of the middle viewpoint; wherein, the preset ratio ranges from 1% to 20%.
