Abstract:
Methods and systems for reducing eye strain for multiple users are described herein. The method includes calculating, for each viewer, a metric representing a degree of eye strain of the viewer based on eye activity of the first viewer. The method further involves determining whether each metric is within a range indicating an acceptable degree of eye strain for each viewer. If a metric is not within the range indicating an acceptable degree of eye strain, then, for each viewer, a subset of display settings that is known to cause the metric to be within the viewer's range is identified. The method further involves identifying an additional subset of display settings, where the additional subset is made up of display settings that are also in each viewer's subset. A display setting is selected from this additional subset, and the display is generated according to the selected display setting.

Abstract:
A device (1000) for use with first stereoscopic data, second stereoscopic data and a display device. The device includes an input portion (1006), a convergence data detecting portion (1008), a convergence plane portion (1010), a comparing portion (1012) and a modification portion (1014). The input portion (1006) can receive the first stereoscopic data and the second stereoscopic data. The convergence data detecting portion (1008) can detect first convergence data within the first stereoscopic data and can detect second convergence data within the second stereoscopic data. The convergence plane portion (1010) can determine a first convergence plane based on the first convergence data and can determine a second convergence plane based on the second convergence data. The comparing portion (1012) can compare the first convergence plane and the second convergence plane and can generate a convergence plane comparison. The modification portion (1014) can modify the first convergence data based on the convergence plane comparison.
Abstract:
Three-dimensional [3D] display device (100) for processing a depth-related signal (122), the 3D display device comprising: -an input (120) for obtaining the depth-related signal, the depth-related signal comprising depth-related values distributed within a signal depth-related range (310), the depth-related values enabling 3D rendering of a two-dimensional [2D] image signal (124) on the 3D display device; -a processor (140) for mapping the depth-related values to a display depth-related range (320) of the 3D display device to obtain adjusted depth-related values for use in the 3D rendering; and -the processor (140) being arranged for, as part of said mapping the depth-related values, adjusting a distribution of the depth-related values within the display depth-related range (320) based on limitation data (126), the limitation data being indicative of a perceptual quality provided to a viewer as a function of a degree of depth established by the 3D display device.
Abstract:
A 3D video device (50) processes a video signal (41) that has at least a first image to be displayed on a 3D display. The 3D display (63) requires multiple views for creating a 3D effect for a viewer, such as an autostereoscopic display. The 3D video device has a processor (52) for determining a processed view based on the 3D image data adapted by a parameter for targeting the multiple views to the 3D display, and calculating a quality metric indicative of perceived 3D image quality. The quality metric is based on a combination of image values of the processed view and a further view. A preferred value for the parameter is determined based on repeatedly determining and calculating using different values. Advantageously, the quality metric predicts the perceived image quality based on a combination of image content and disparity.
Abstract:
The invention concerns a method and a device for correcting distortion errors in a 3D content viewed by an observer on a screen. The method comprises the step of determining a rendered roundness factor (rrf) of a pinhole model projected cylinder, estimating a rendered roundness factor table depending on the defined distance of the observer to the screen and the disparity values of objects of the image, determining for the observer a disparity transform function (TD) as a function of the estimated rendered roundness factor table and modifying the object disparity values using the disparity transform so that a perceived roundness factor of one is provided.
