Abstract: An optical module includes a light modulator that modulates light and includes a plurality of pixels, and a pixel shift mechanism. The light modulator is driven based on an interlace method. The pixels of the light modulator each include a first sub-pixel on which a first color light flux or a second color light flux is incident, a second sub-pixel on which a color light flux different from the color light flux incident on the first sub-pixel out of the first color light flux and the second color light flux is incident, and a third sub-pixel and a fourth sub-pixel on which a third color light flux is incident. The third sub-pixel and the fourth sub-pixel are arranged in a scan direction of the light modulator. The pixel shift mechanism shifts the light modulator in a direction that intersects the scan direction.

Abstract: A picture signal includes a luminance signal and a color signal. A first predetermined number of sample points of the luminance signal are located on every actual scanning line. A second predetermined number of sample points of the color signal are located on every actual scanning line. The second predetermined number is equal to the first predetermined number multiplied by “1/n”, where “n” denotes a predetermined integer equal to or greater than 2. Virtual scanning lines are set which correspond to respective pairs each having two successive actual scanning lines. Sample points of the color signal are moved from each pair of two successive actual scanning lines to a corresponding virtual scanning line while being rearranged thereon so that the picture signal is converted. The total number of sample points of the color signal per virtual scanning line is equal to the first predetermined number multiplied by “2/n”.
