Temporal cadence perturbation for time-division stereoscopic displays

摘要

One or more techniques to reduce or eliminate the false depth of objects that move along the axis of ocular separation when displayed using time division multiplexing. Experiments can be performed to determine a perceived depth of an object moving with known velocity. Then, when rendering stereoscopic image pairs, the location of the object can be modified to change the perceived stereoscopic depth of the object to compensate for the false depth. In one technique, the images can be displayed with alternating left- and right-precedence to reduce the perception of false depth.

1. A computer-implemented method to compensate for false depth of a target object resulting from stereoscopic time division multiplexing when the target object moves along an axis of ocular separation, the computer-implemented method comprising:
receiving input specifying which object in a plurality of displayed objects, each having a fixed depth value, appears at a depth that is most similar to a perceived depth of an initial, moving object distinct from the target object and the object specified by the received input; receiving a sequence of stereoscopic image pairs to be displayed using stereoscopic time division multiplexing; determining a screen space velocity of the target object moving along the axis of ocular separation in the sequence of images, wherein the screen space velocity of the target object corresponds to that of the initial, moving object; determining a relative depth offset of the target object between a left image and a right image of a stereoscopic image pair, based on the fixed depth value of the object specified by the received input; and determining a modified depth of the target object based on the screen space velocity and the relative depth offset, wherein the modified depth alters a perceived depth of the target object to an intended depth of the target object, thereby compensating for the false depth of the target object resulting from stereoscopic time division multiplexing when the target object moves along the axis of ocular separation.
