摘要： Growth and clustering of halftone dots is a drawback in the reproduction of halftoned continuous tone images on prior art recording materials. Certain thermographic materials show a local microdot shrink effect called negative cross-talk upon neighboring microdots when exposing a microdot. Exposing these materials according to the frequency modulated halftone data of an image results in better tone rendering and lower noise due to lower dot clustering or negative cross-talk characteristics.

摘要： An image information recording method, comprising the steps of: (a) imagewise exposing to light a silver halide color photographic light-sensitive material comprising a support having thereon a light-sensitive layer containing a silver halide and a color coupler; (b) subjecting the photographic light-sensitive material to color development so as to obtain an image in the photographic light-sensitive material; (c) converting the image in the photographic light-sensitive material to electric image information using a scanner comprising a light source part and a light receiving part while at least 80% of the developed silver and the silver halide remains in the photographic light-sensitive material; and (d) recording the electric information on a recording medium, wherein, the step (c) is carried out with the scanner that exhibits a light diffusion coefficient of at least 0.8.

摘要： Process for determining a mask for changing a brightness profile of a photographic copy with the following steps: photographic image data are derived from photographically recorded image information; optimized image data are obtained by correction of the photographic image data, wherein errors which were created to during the photographic recording of the image information are considered; a brightness mask, the values of which embody an influencing of the brightness profile of the photographic copy is determined based on the optimized image data.
摘要翻译：用于通过以下步骤确定用于改变照相副本的亮度轮廓的掩模的处理：摄影图像数据从照相记录的图像信息导出; 通过校正摄影图像数据获得优化的图像数据，其中考虑在图像信息的照相记录期间产生的错误; 基于优化的图像数据确定亮度掩模，其亮度掩模的值受照片拷贝的亮度特征的影响。
