    • An image processing apparatus for correcting degradation of an image due to an aberration of an optical imaging system with respect to image data obtained by sensing an object image entering through the optical imaging system using an image sensor. The image processing apparatus comprises selection means (1002) for selecting a filter to be used for recovery processing in accordance with an image sensing condition at the time of the image sensing, image processing means (1004) for performing recovery processing for the image data by using the filter selected by the selection means, and correction means (1005, 1006, 1007) for determining a correction value based on a difference between the value of a pixel before and after recovery processing by the image processing means, and correcting the pixel value before the recovery processing by the image processing means using the determined correction value.
    • 一种图像处理装置,用于根据通过使用图像传感器感测通过光学成像系统进入的对象图像获得的图像数据,校正由于光学成像系统的像差导致的图像的劣化。 图像处理装置包括:选择装置,用于根据图像感测时的图像感测条件来选择要用于恢复处理的滤波器;图像处理装置,用于通过图像数据执行图像数据的恢复处理; 使用由选择装置选择的滤波器和校正装置(1005,1006,1007),用于基于图像处理装置的恢复处理之前和之后的像素的值之间的差来确定校正值,并且校正像素值 在由图像处理装置使用所确定的校正值的恢复处理之前。

    • To provide a method for manufacturing an optical film laminate including a polarizing film comprising polyvinyl alcohol type resin formed on a non-crystallizable ester type thermoplastic resin substrate in the form of a continuous web and having a dichroic material impregnated therein in an oriented state, the polarizing film having optical properties defined in terms of a single layer transmittance T and a polarization rate P of a specific level.
      [Means for accomplishing the Objects]
      The method comprises processes of subjecting a laminate comprising the non-crystallizable ester type thermoplastic resin substrate and the polyvinyl alcohol type resin layer formed on the non-crystallizable ester type thermoplastic resin substrate to an elevated temperature in-air stretching to form a stretched laminate comprising a stretched intermediate consisting of a molecularly oriented polyvinyl alcohol type resin, impregnating the dichroic material in the stretched laminate to form a dyed laminate including a dyed intermediate comprising a polyvinyl alcohol type resin layer having the dichroic material impregnated therein in an oriented state, and stretching the dyed laminate in boric acid solution to form an optical film laminate including a polarizing film comprising the polyvinyl alcohol type resin having the dichroic material impregnated therein in an oriented state.
