    • The present invention is directed to an image processing device which is capable of discriminating the classification of a particular area of an image at improved accuracy. In an image processing device according to the present invention, an image input from an image signal input portion is processed in the following steps: a vertical and horizontal complexity calculating circuit determines absolute values Tx and Ty of differential densities between pixels neighboring to each other in vertical and horizontal directions, respectively, within a particular area of the image; a diagonal complexity calculating circuit determines absolute values Rx and Ry of differential densities of pixels neighboring to each other in main diagonal and sub diagonal directions, respectively, within the particular area; a comparator circuit compares sums of absolute values in respective directions and outputs a least sum as a complexity to an area discriminating portion; a difference-comparator portion determines a difference between a maximal value Ma and a least value Mi of densities of pixels of the image data and outputs it as a comparison difference value to the area discriminating portion; and the area discriminating portion discriminates the classification of the image area based on the above-mentioned complexity value and comparison difference value.
    • 本发明涉及一种图像处理装置,其能够以更高的精度区分图像的特定区域的分类。 在根据本发明的图像处理装置中,从图像信号输入部分输入的图像在以下步骤中被处理:垂直和水平复杂度计算电路确定彼此相邻的像素之间的差分密度的绝对值Tx和Ty 分别在图像的特定区域内的垂直和水平方向; 对角线复杂度计算电路分别确定特定区域内的主对角线和副对角线方向上彼此相邻的像素的差分密度的绝对值Rx和Ry; 比较器电路对各个方向的绝对值的和进行比较,并将最小值作为复杂度输出到区域识别部分; 差分比较部分确定图像数据的像素密度的最大值Ma和最小值Mi之间的差,并将其作为比较差值输出到区域识别部分; 并且区域识别部分基于上述复杂度值和比较差值来区分图像区域的分类。

    • A vaporizer apparatus enables efficient vaporization of a liquid material for the production of high dielectric thin film devices by allowing a sufficient dwell time for complete vaporization of the feed liquid. The vaporizer apparatus also prevents degradation of the feed gas after vaporization and provides a stable supply of the vaporized feed gas to the substrate. The vaporizer apparatus comprises an outer member having a cylindrical inner surface, and an inner member having a cylindrical outer surface opposing the cylindrical inner surface of the outer member. A feed material passage having a spiral configuration is formed on at least one of the cylindrical inner surface and the cylindrical outer surface. The feed material passage communicates with a feed liquid entry opening and a feed gas exit opening. A heating device is provided for heating at least one of the outer member and inner member.
