    Abstract: An image processing apparatus and method, and a program are provided to perform correction according to two-dimensional image processing for values of pixels constructing image data without depending on two-dimensional filtering. An image processing apparatus includes a horizontal image processor(21), a vertical image processor(22), a tilted image processor(23,24), a correction determination unit, and a corrector(30). The horizontal image processor performs image processing for the value of a noted pixel among pixels constructing image data using values of pixels including the noted pixel, which are arranged in the horizontal direction. The vertical image processor performs image processing for the value of the noted pixel using values of pixels including the noted pixel, which are arranged in the vertical direction. The tilted image processor carries out image processing using values of pixels arranged in a tilted direction different from the horizontal and vertical directions. The correction determination unit determines the quantity of correction for the value of the noted pixel based on the processing results of the vertical image processor, the horizontal image processor and the tilted image processor. The corrector adds the quantity of correction to the value of the noted pixel in order to correct the value of the noted pixel.

    Abstract translation: 提供图像处理装置和方法以及程序以根据二维图像处理对构成图像数据的像素的值执行校正，而不依赖于二维滤波。 图像处理装置包括水平图像处理器（21），垂直图像处理器（22），倾斜图像处理器（23,24），校正确定单元和校正器（30）。 水平图像处理器使用在水平方向上布置的包括所述像素的像素的值来对构成图像数据的像素中的所述像素的值进行图像处理。 垂直图像处理器使用在垂直方向上布置的包括所述像素的像素的值来执行所述像素的值的图像处理。 倾斜图像处理器使用以与水平和垂直方向不同的倾斜方向布置的像素的值进行图像处理。 校正确定单元基于垂直图像处理器，水平图像处理器和倾斜图像处理器的处理结果来确定针对所述像素的值的校正量。 校正器将校正量添加到所述像素的值，以便校正所述像素的值。

    Abstract: PCT No. PCT/JP88/00286 Sec. 371 Date Jan. 10, 1989 Sec. 102(e) Date Jan. 10, 1989 PCT Filed Mar. 18, 1988 PCT Pub. No. WO88/07307 PCT Pub. Date Sep. 22, 1988.A noise reduction circuit in which a first signal (S h2) is obtained by passing the input video signal (S I ) through a low frequency shut-off filter (10) and another a limiter (11), a second before signal (S H21) is obtained by passing the above obtained signal (S H2) through a field or frame delay circuit (5) and the difference between the two signals (S H2- SH21) is subtracted from the above input video signal (S I ) so as not to lower the definition of image, the noise reduction circuit being capable of application in a television receiver etc.
