Abstract: A laryngoscope with a rotatable and turnable display is revealed. The laryngoscope includes a laryngoscope body, a rotating assembly, a turnover assembly and a display. The laryngoscope body is used to capture images. The rotating assembly is disposed over the laryngoscope body and having a plurality of elastic bodies or first and second magnetic parts used in combination with a slot of a first fixed shaft. Thus the display is rotated around the rotating assembly and a rotation angle of the display is determined according to the position of the slot. The turnover assembly is arranged at one side of the display. The display is flipped around the turnover assembly by a fixing member of a second fixed shaft being mounted into at least one fixing hole of a turnover portion. The angle of the display being turned is determined according to the position of the fixing hole.

Abstract: A method for creating a uniformity compensation look-up table is revealed. The method includes the following steps. First measure a plurality of areas on a plane users intend to make uniform to get a measured value of the respective area. Then get a central uniform estimate of a center of the plane. Also get a linear skeleton according to the position of one of the measured values and the position of the central uniform estimate. Next get a plurality of skeletal uniform estimates on the linear skeletons respectively by interpolation or extrapolation of the measured values, the central uniform estimate, and the distance between the position of the measured values and the center of the plane. At last get a plurality of planar uniform estimates on the plane in turn according to the skeletal uniform estimates of the two adjacent linear skeletons to establish the look-up table.
