US 2014/0192168 A1 · IMAGE PROCESSING DEVICE, METHOD, AND STEREOSCOPIC IMAGE DISPLAY DEVICE

Abstract

According to an embodiment, an image processing device provides a stereoscopic image to be displayed on a display and includes an acquisition unit, first and second calculators, a selector, and a determiner. The acquisition unit acquires observer information. The first calculator calculates, a viewpoint vector pointing from one to another of the observer position of each observer and the display, and an eye vector pointing from one to another eye of the observer, based on the observer information. The second calculator calculates a weight indicating a degree of desirability of stereoscopic viewing for each observer when the stereoscopic image according to one of display parameters is displayed on the display) by using the viewpoint vector and the eye vector of the observer. The selector selects one display parameter based on the weight. The determiner determines the stereoscopic image according to the selected display parameter.

Dependent claims

An image processing device that provides a stereoscopic image to he displayed on a display, the device comprising:

an acquisition unit configured to acquire observer information including a position o at least one observer;
a first calculator configured to calculate, a viewpoint vector pointing from one to another of the position of each observer and the display, and an eye vector pointing from one eye to another eye of the observer, basest on the observer information;
a second calculator configured to calculate a weight indicating a degree of desirability of stereoscopic viewing for each observer when the stereoscopic image according to one of display parameters is displayed on the display, by using the viewpoint vector and the eye vector of the observer;
a selector configured to select one of the display parameters based on the weight;
and
a determiner configured to determine the stereoscopic image according to the selected display parameter.

3 more elements

The device according to claim. 2 wherein the weight takes a greater value in a case a first relationship and a second relationship satisfy a specific condition than in a case where the specific condition is not satisfied, the first relationship being a relationship of a direction of the viewpoint vector and a direction of a vertical vector indicating a vertical direction of a parallax image included in the stereographic image, and the second relationship being a relationship of a direction of a parallax vector and a direction of the eye vector, the parallax vector indicating an amount of parallax between the parallax images.

A stereoscopic image display device comprising:

a display configured to display a stereoscopic image;
an acquisition unit configured to acquire observer information including a position of at least one observer;
a first calculator configured to calculate, a viewpoint vector pointing from one to another of the position of each observer and the display, and an eye vector pointing from one eye to another eye of the observer, based on the observer information;
a second calculator configured to calculate a weight indicating a degree of desirability of stereoscopic viewing for each observer when the stereoscopic image according to one of display parameters is displayed on the display, by using the viewpoint vector and the eye vector of the observer;
a selector configured to select one of the display parameters based on the weight;
and
a determiner configured to determine the stereoscopic image according to the selected display parameter.
