    • An image processing apparatus includes a sort unit for sorting original image data into edge image data and planar image data, a first coding unit for coding the sorted planar image data according to the fractal block coding method, and a second coding unit for coding the sorted edge image data according to a coding method differing from the fractal block coding method. Thus, an image processing apparatus is provided that can have picture quality of a reproduced image improved even for a block that has maximum density difference such as an edge portion. The image processing apparatus can include a first coding unit for coding original image data according to the fractal block coding method, an extractor for extracting error between blocks, a comparator for comparing the amount of extracted error with a predetermined value, and a second coding unit for coding error information according to a coding method different from the fractal block coding method when the error amount is greater than the predetermined value as a result of comparison.
    • 图像处理装置包括:分类单元,用于将原始图像数据分类为边缘图像数据和平面图像数据;第一编码单元,用于根据分形块编码方法对分类的平面图像数据进行编码;以及第二编码单元, 根据与分形块编码方法不同的编码方法的边缘图像数据。 因此,提供了即使对于诸如边缘部分具有最大密度差的块,也能够改善再现图像的图像质量的图像处理装置。 图像处理装置可以包括:第一编码单元,用于根据分形块编码方法对原始图像数据进行编码;提取器,用于提取块之间的误差;比较器,用于将提取的误差量与预定值进行比较;以及第二编码单元 作为比较结果,当误差量大于预定值时,根据与分形块编码方法不同的编码方法编码错误信息。

    • A vibration actuator includes an elastic body on which at least one projection is formed and a vibrating body including an electromechanical conversion device, and drives a driven member that is in contact with a contact portion of the projection by causing an end portion of the projection to perform an ellipsoidal movement in response to a combination of two vibration modes generated in the vibrating body when an alternating driving voltage is applied. The elastic body is formed integrally with the projection and a bonding portion between the projection and the electromechanical conversion device. A space is provided between the contact portion and the electromechanical conversion device to which the projection is bonded. The spring portion is provided between the bonding portion and the contact portion and causes the projection to exhibit a spring characteristic when the contact portion is pressed by the driven member.
    • 振动致动器包括:弹性体,其上形成有至少一个突起;以及振动体,其包括机电转换装置,并且通过使突起的端部通过突出部的端部驱动与突起的接触部分接触的从动构件 当施加交替的驱动电压时,响应于在振动体中产生的两种振动模式的组合来执行椭圆运动。 弹性体与突起一体地形成,并且在突起和机电转换装置之间形成接合部。 在接触部和与该凸起接合的机电转换装置之间设置有空间。 弹性部分设置在接合部分和接触部分之间,并且当接触部分被被驱动部件按压时,使突起呈现出弹簧特性。
