Provided is a method and system for performing color look-up table and gamma correction for video pixel data. One or more blades expand in directions non-parallel to the plane of the respective blades and form an effective cutting sphere preferably greater-than-180-degrees for greater flexibility in placement of the reamer shaft relative to the center of axis of the acetabulum. Kits including devices according to the present invention in sterile packaging, and methods of making and using devices according to the present invention, are also described. Then, there is recording a gain of every pixel by a brightness regulator using an image gains memory buffer zone, the gain being regulated according to detection results of the static image detector. The driving controller controls the driver by a sequence of pulse signals so as to position the shading member at the shading position for a shading-interval in the one-frame reading interval, and so as to position the shading member at the non-shading position for a remaining reading-interval.
