Abstract: PROBLEM TO BE SOLVED: To provide a gradation display method, a multilevel voltage generating device and a picture display device in which flicker is reduced and display quality is not changed by gradation at the time of displaying a halftone while generating an effective halftone voltage by changing over a reference voltage corresponding to a certain gradation and a reference voltage corresponding to a gradation higher by one step. SOLUTION: A first fluctuation reference voltage vn corresponding to a first gradation level and a second fluctuation reference voltage vn+1 corresponding to a second gradation level whose fluctuation amplitudes are made to be smaller than ΔV being the difference between the reference voltage Vn and the reference voltage Vn+1. Then, an intermediate fluctuation voltage vm is generated by selectively changing over both reference voltages Vn, Vn+1 in accordance with a fluctuation frequency. Thus, since the amplitude of the intermediate fluctuation voltage vm is made to be smaller than ΔV and, also, fluctuation frequencies are made to be even among respective voltages vn, vn+1, vm, the purpose can be achieved.

Filed: 2000-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a video editing system which can complete processing for extracting plural short videos from video to be edited for a shorter time than conventional processing. SOLUTION: In a video editing system, after video to be edited is rewinded to the head (S103), reproduction is started (S109), and a short video is taken in based on edition information (S111-S127).
