    • There is provided a method of reducing block noise, mosquito noise and other image noises in an image by a filtering process using a smoothing filter, which block noise, mosquito noise and other image noises being caused at the time of decoding encoded, compressed image data on a block-by-block basis. The method includes changing the extent or intensity of the image noise reduction in the filtering process in a continuous or stepwise manner according to an output size or expansion rate of an image to be outputted to printer paper, photographic paper or other output media, thereby allowing the extent or intensity of the image noise reduction to be increased as the output size or expansion rate of the image increases. This method is capable of allowing the extent of the image noise reduction applied to image data to be perceived in a similar fashion, irrespective of the output size.

    • A method of detecting the base concentration of a film comprises the steps of generating a concentration histogram from the film image in each of the RGB color components, shifting and stretching the histograms in the other colors towards the histogram in the reference color in the concentration axial direction, calculating an superimposed area between the two histograms in the two color components after the stretching process, and finding the shift rate and the stretch ratio when a total of the respective superimposed areas calculated is the greatest value. As the minimum of the lowest concentration in the histograms at the shift rate and the stretch ratio determined is specified to represent the location of the base concentration in the original histogram, the base concentration in each color component of the film can be calculated from the location of the base concentration in the histogram.
    • 检测膜的基底浓度的方法包括以下步骤:从RGB颜色成分中的每一个中的胶片图像生成浓度直方图,将其它颜色的直方图移动并以参考颜色的浓度轴向的直方图 计算拉伸处理后的两个颜色分量中的两个直方图之间的叠加区域,并且当计算的各个叠加区域的总和为最大值时,求出移动速率和拉伸比。 由于在移位速率下的直方图中最低浓度的最小值和确定的拉伸比指定为表示原始直方图中的基准浓度的位置,所以可以从该位置计算每个彩色成分中的基准浓度 的直方图中的碱浓度。

The information of screen data displayed on a screen is acquired, and the active screen data is captured when determined that the active screen data is from application software to be captured based on the information of the screen data. In the capture processing step, an image data of a current active screen is presumptively configured so as to include a last active screen retrieved immediately before said current active screen that is positioned in a screen region other than said current active screen. A pixel difference between a pixel date of a current full-screen region and a pixel date of a last full-screen region is taken, and the pixel difference data as said active screen data is retrieved.
