An image display system (1200, 1400), the system comprising: a position sensing unit (1210, 1410) adapted for sensing a position of a user or one or two eyes of the user; a viewpoint calculating unit (1220, 1430) adapted for calculating a viewpoint corresponding to the sensed position; a rendering unit (1230, 1440) adapted for setting a first sub-pixel, of a three-dimensional pixel having plural sub-pixels, to have a color component value of a first color component of a viewpoint image of the first sub-pixel, with a viewpoint of the first sub-pixel and the viewpoint image of the first sub-pixel being determined to be corresponding to the calculated viewpoint, and adapted for setting at least one other sub-pixel of the 3D pixel having a different viewpoint from the viewpoint of the first sub-pixel to have a color component value of a second color component, different from the first color component, of the viewpoint image of the first sub-pixel, wherein each sub-pixel of the 3D pixel has a different viewpoint image, wherein the other sub-pixel corresponds to a viewpoint adjacent to the calculated viewpoint; and a display unit (1240, 1450) adapted for displaying the color component value of the first color component using the first sub-pixel and the color component value of the second color component using the at least one other sub-pixel, wherein the display unit (1240, 1450) is adapted for displaying, from the 3D pixel, viewpoint images of at least two viewpoints being different from each other using one of a lenticular lens, a parallax barrier, prism arrangement, and a directional backlight, characterized in that the display unit (1240, 1450) is adapted for displaying the 3D pixel, the 3D pixel being configured such that an optical axis through a first sub-pixel of the 3D pixel and a first sub-pixel of another 3D pixel, for a same viewpoint, is inclined at an angle with respect to the vertical direction of the display, the angle being defined by a ratio of a size of N pixels in a vertical direction of the 3D pixel to a size of M sub-pixels in a horizontal direction of the 3D pixel, wherein N and M are integers, such that each viewpoint corresponds to a single color. a position sensing unit (1210, 1410) adapted for sensing a position of a user or one or two eyes of the user; a viewpoint calculating unit (1220, 1430) adapted for calculating a viewpoint corresponding to the sensed position; a rendering unit (1230, 1440) adapted for setting a first sub-pixel, of a three-dimensional pixel having plural sub-pixels, to have a color component value of a first color component of a viewpoint image of the first sub-pixel, with a viewpoint of the first sub-pixel and the viewpoint image of the first sub-pixel being determined to be corresponding to the calculated viewpoint, and adapted for setting at least one other sub-pixel of the 3D pixel having a different viewpoint from the viewpoint of the first sub-pixel to have a color component value of a second color component, different from the first color component, of the viewpoint image of the first sub-pixel, wherein each sub-pixel of the 3D pixel has a different viewpoint image, wherein the other sub-pixel corresponds to a viewpoint adjacent to the calculated viewpoint; and a display unit (1240, 1450) adapted for displaying the color component value of the first color component using the first sub-pixel and the color component value of the second color component using the at least one other sub-pixel, wherein the display unit (1240, 1450) is adapted for displaying, from the 3D pixel, viewpoint images of at least two viewpoints being different from each other using one of a lenticular lens, a parallax barrier, prism arrangement, and a directional backlight, characterized in that the display unit (1240, 1450) is adapted for displaying the 3D pixel, the 3D pixel being configured such that an optical axis through a first sub-pixel of the 3D pixel and a first sub-pixel of another 3D pixel, for a same viewpoint, is inclined at an angle with respect to the vertical direction of the display, the angle being defined by a ratio of a size of N pixels in a vertical direction of the 3D pixel to a size of M sub-pixels in a horizontal direction of the 3D pixel, wherein N and M are integers, such that each viewpoint corresponds to a single color.
