摘要： A color camera system according to an example includes a red, green, blue (RGB) color camera device to capture images of an object, and a polarized illumination source to illuminate the object during the capture of the images. The color camera system further includes a liquid crystal tunable polarization filter positioned between the camera device and the object, wherein the liquid crystal tunable polarization filter is to provide the camera device with selectable linear polarization viewing states for capturing the images of the object, and is to provide capability for each RGB pixel to be uniquely processed using RGB color distinct polarization filter parameters.

摘要： A projection optical system includes: a first lens group; a second lens group; a third lens group; a fourth lens group; a fifth lens group; a sixth lens group; a seventh lens group; an eighth lens group; and a ninth lens group, and these lens groups are in an order from a magnification side to a reduction side. The projection optical system includes an aperture stop disposed between the second lens group and the eighth lens group. The first lens group has negative power and includes one first aspherical lens. Any one of the second lens group, the third lens group, the fourth lens group, the fifth lens group, the sixth lens group, the seventh lens group, the eighth lens group, and the ninth lens group includes at least one second aspherical lens. During zooming, the first lens group and the ninth lens group are fixed, and the second lens group, the third lens group, the fourth lens group, the fifth lens group, the sixth lens group, the seventh lens group, and the eighth lens group move.

摘要： Provided are a device and a method by which high-precision auto focus (AF) processing can be performed while a focus lens or a zoom lens is being operated. An interchangeable lens acquires position information regarding a focus lens and a zoom lens at a predetermined time interval during an exposure time period of detection information acquisition pixels for use in calculation of a defocus amount (DF), and outputs the position information to an imaging device. The imaging device calculates the defocus amount (DF) by using information regarding the detection information acquisition pixels, calculates a reference focus lens position (Ref_fc) by using points, on a cam curve, corresponding to the inputted lens position information, calculates a target focus lens position (Tgt_fc) in an in-focus position, from the reference focus lens position (Ref_fc) and the defocus amount (DF), and outputs the target focus lens position (Tgt_fc) to the interchangeable lens.

摘要： A turner apparatus, adapted for supportively disposed between two surfaces of two objects so as to allow the two objects rotating with respect to each other, includes a frame body and a rotor mechanism. The frame body includes a ring-shape turner frame and a ring-shape support turner, wherein the turner frame having a ring-shape rotor chamber formed therein and said support turner is rotatably mounted at an opening of the rotor chamber to enclose the rotor chamber. The rotor mechanism which is rotatably received in said rotor chamber includes a plurality of rotors and a ring-shape retainer unit configured to intervally retain the plurality rotors in a rotatable manner. The turner frame has a first rolling surface and the support turner has a second rolling surface, wherein the first and second rolling surfaces are positioned face to face to define a rolling track channel such that each of the plurality of rotors is capable of revolving along the rolling track channel.
