    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.

    摘要: A method and apparatus for correcting for vignetting include associating each pixel in the two-dimensional array with a pair of polar coordinates referenced to a preselected origin pixel and partitioning the two-dimensional array of image pixels into a plurality of sectors. For each sector, the method includes computing an average R value, an average G value and an average B value; converting the average R value, the average G value and the average B value for each sector to logarithm space; comparing color gradients along a radial sector line to a gradient threshold; selecting gradients that do not exceed the threshold; using the selected gradients, estimating parameters of a model of a lens which produced the image; and, using the parameters, updating the model of the lens and correcting the image.

    摘要: A fluid dispensing oral care implement having a low profile pump includes a head, a reservoir for storing an oral care fluid, at least one liquid outlet in the head, and a pump. The pump includes a flexible membrane movable between alternating pump intake and discharge motions. The pump includes inlet and outlet flap valves, which may be formed integrally from portions of the membrane. In one embodiment, the valves are integrally formed in the membrane as flexible cantilevered tabs movable between open and closed positions. In some embodiments, the pump may be mounted in the toothbrush head or forms the head. In some embodiments, the pump may be disposed in a neck or a handle portion of the toothbrush.
