A method of displaying successive stereoscopic image pairs comprises: capturing, at a predetermined image rate, a sequence of images suitable for a left eye of a viewer and capturing, at the predetermined image rate, a corresponding sequence of images suitable for a right eye of the viewer; and displaying a sequence of stereoscopic image pairs at the predetermined image rate, in which each displayed stereoscopic image pair comprises one left image suitable for the left eye of the viewer and one right image suitable for the right eye of the viewer, the one left and one right images being derived from the captured sequence of images suitable for the left and right eye of the viewer, respectively; in which: the one left image and the one right image of each stereoscopic image pair are displayed for different respective portions of an image period defined by the predetermined image rate; and the effective temporal position of the one left image of a stereoscopic image pair for display is different to the effective temporal position of the one right image of that stereoscopic image pair.
