An LCD groups pixels in each row into a plurality of blocks, and calculates difference in gray between every two image data applied to a pair of adjacent odd and even pixels in each block including pixels in a row for each of first to third colors. It is determined that a block is first or second dot block depending on a sign of the gray difference when a magnitude of the gray difference between the odd pixel and the even pixel in each pair in the block for at least one color is equal to or larger than a critical value. A current block in a current row and in columns is determined to be a one-dot block when the current block is the first dot block and a previous block in a previous row and in the columns is the second dot block. When the number of the one-dot blocks is a predetermined percentage of the number of the total blocks, it is determined that a one-dot pattern is generated and one-dot inversion of the LCD is changed into another inversion. In this way, a pattern generating flicker is determined and the inversion type is changed for reducing the flicker.

Video display device

The concentration(s) of element(s) contained in an unknown sample is measured without necessity of judging the sample relying on a human's eye and obtaining information from a supplier of the sample previously. The concentration(s) of trace element(s) such as Cd, Pb and Hg contained in parts for electronic or electric equipment is determined by (1) irradiating the sample with an X-ray so as to identify whether the type of the sample is a nonmetal-based material or a metal-based material; (2) selecting measuring conditions for a fluorescent X-ray analysis depending on the identified type of the sample; and (3) measuring the concentration(s) of one or more element(s) contained in the sample by the fluorescent X-ray analysis according to the selected measuring conditions.
