摘要： A photographic photosensitive material and a photographic printing system are provided which can prevent deterioration in image quality even in a case in which a photographic photosensitive material which does not have a color correcting function or a sharpness enhancing function is subjected to printing processing. An identification code recorded in advance on the photographic film is read. Prescan conditions are computed in accordance with the identification code, and prescanning is carried out. On the basis of a prescan image, fine scan conditions are computed, and fine scanning is carried out. Further, parameters for color correction and parameters for sharpness processing which correspond to the identification code are read. Read parameters are outputted to an automatic set-up engine, and image processing is carried out by combining designated parameters.

摘要： Provided is a system for eliminating background noise, i.e. unwanted dots of ink in the background of a document which is to be reproduced by a copier. An STS module collects statistics on a stream of pixels representing an original document generated by a scanner of the copier. The statistics are used by an MIC module to determine a reference background color value of the scanned document. The reference background color value and pixel values of pixels included in the pixel stream are compared by an RTE module and the results of comparison are used to adjust, when necessary, the pixel values remove the undesirable background noise.

摘要： A method for correcting a white line artifact between low and high frequency printed pixels. A printer may be able to print either a high or low frequency halftone pixels in some locations, but may be able to print only high frequency halftone pixels in other locations, the latter known as out of phase locations. If the image data is in run length encoded form, and the printer tries to print a low frequency pixel in an out of phase location, no pixel will be printed in that location and a white space results. The remedy is to test at the beginning and end of low frequency runs bordering high frequency runs. If the first (last) low frequency pixel of an original run is in an out of phase location, a one pixel run of the high frequency screen and of the low frequency color is added before (after) the original run, and the run length of the low frequency run is decreased by one pixel.

摘要翻译： 一种用于校正低频和高频印刷像素之间的白线伪迹的方法。 打印机可能能够在某些位置打印高频或低频半色调像素，但是可以仅在其它位置（后者称为异相位置）中仅打印高频半色调像素。 如果图像数据是运行长度编码形式，并且打印机尝试在异相位置中打印低频像素，则不会在该位置打印像素并产生空白空间。 补救措施是在高频运行的低频运行的开始和结束时进行测试。 如果原始运行的第一（最后）低频像素处于异相位置，则在原始运行之前（之后）添加高频屏幕和低频颜色的一个像素运行，并且运行长度 的低频运行减少了一个像素。

摘要： The image processing method and apparatus display a processed image on a monitor as it is reproduced from processed image data obtained by performing specified processing schemes on input image data obtained from a picture optically taken with a taking lens, designate a portion of the processed image on the monitor to create a designated area in accordance with a state of an aberration in the processed image due to the taking lens, determine a corrective value for correcting the aberration based on an information in the input image data for the designated area and correct, based on the corrective value, the aberration on the input image data obtained from the picture and outputting the corrected image data. When the image suitable for outputting a print is obtained from the picture optically taken with the taking lens by the correction of the aberrations due to the taking lens is performed manually, the correction of the aberrations is capable of performing in a uniform and appropriate manner independently of the operator's experience and obtaining efficiently a satisfactory finished print.

摘要： A method for automatic removal of image artifacts includes the steps of comparing scanned image data pertaining to regions where it is possible for image artifacts to be present to idealized image artifact data, determining whether image artifacts or partial image artifacts are present in the known regions, excluding such regions or portions of them as appropriate from a scannable area, and generating an image from the elements of the scanned image data pertaining only to the portions of the scannable area for which no image artifacts are determined to be present.

摘要： In an image processing method, wherein image processing is carried out on an original image signal representing an original image, graininess and/or sharpness of the original image is estimated in accordance with the original image signal. The image processing is then carried out on the original image signal and in accordance with the graininess and/or the sharpness having been estimated, and a processed image signal is thereby obtained. The image processing optimum for an image can thereby be carried out regardless of graininess and/or sharpness of the image.
