    摘要: Optical position input systems and methods determine positions of at least one pointing objects within an active touch area. At least three imager modules form images of at least one pointing objects within the active touch area. A processor computes a position of each of the at least one pointing object based upon the images formed by the at least three imager modules.

    摘要: An image sensor includes an array of light sensitive elements and a filter array. Each filter element is in optical communication with a respective light sensitive element. The image sensor receives filtered light having a repeating pattern. Light sensitive elements in at least two successive rows alternately receive light having a first color and a second color, and light sensitive elements in common columns of the successive rows alternately receive light having the first color and the second color. Light sensitive elements in at least two additional successive rows alternately receive light having a third and a fourth color, and light sensitive elements in common columns of the additional successive rows alternately receive light having the third color and the fourth color. Output values of pairs of sampled light sensitive elements receiving light of a common color and from successive rows are combined to generate a down-sampled image.

    摘要: An image sensor for three-dimensional (“3D”) imaging includes a first, a second, and a third pixel unit, where the second pixel unit is disposed between the first and third pixel units. Optical filters included in the pixel units are disposed on a light incident side of the image sensor to filter polarization-encoded light having a first polarization and a second polarization to photosensing regions of the pixel units. The first pixel unit includes a first optical filter having the first polarization, the second pixel unit includes a second optical filter having the second polarization, and the third pixel unit includes a third optical filter having the first polarization.
