Abstract: A video processing method comprises the steps of dividing an entire input data region into three of first, second and third regions in order from the low level side thereof; setting, as an output data characteristic to input data, a trapezoidal characteristic which is nonlinear and continuous as a whole and consists of a linear portion in the first region where the gain is greater than one, a linear portion in the second region where the gain is equal to one exactly or approximately, and a linear portion in the third region where the gain is smaller than one; setting, as another output data characteristic to the input data, an S-shaped characteristic which is nonlinear and continuous as a whole and consists of linear portions in the first and third regions where the gain is smaller than one, and a linear portion in the second region where the gain is greater than one; selecting either the trapezoidal characteristic or the S-shaped characteristic; and correcting the digital luminance data in accordance with th

Abstract: A cosmetic stick container includes a housing sleeve, an inner sleeve provided inside the housing sleeve so as to be advanceble and retractable along a length of said housing sleeve, a cosmetic stick molded directly inside the housing sleeve having a capsule attached thereto so as to be secured to the inner sleeve, and a mold lubricant constituted of a composition having low compatibility with a composition of the cosmetic stick. The mold lubricant is applied on inner surfaces of the housing sleeve and the capsule.

Abstract: A picture quality adjustment method is disclosed wherein, if a user performs a picture quality adjustment operation once, even if a picture quality adjustment operation is not performed any more for video software of the same authoring, genre or image characteristic, an image of an optimum picture quality can be obtained. When a disk ID of a disk to be played back is not stored in a first memory, it is discriminated whether or not characteristic describing information then and corresponding picture quality adjustment data are stored in a second memory. If such data are not stored, then the picture quality is set to a preset condition, but if such data are stored, then the picture quality adjustment data are read out and picture quality adjustment is executed.
