摘要： An image processing apparatus binarizes input multi-level pixel data by changing the same either to the minimum density data corresponding to white or to a minimum reproducible density data corresponding to the minimum density level reproducible by an image forming apparatus such as a printer, when the density defined by the input multi-level pixel data is of such a low level that it cannot be reproduced by the image forming apparatus. Error incurred by the binarization is reflected in the succeeding binarizing process so that the density of the whole image is preserved, whereby an image with a highlight portion can be recorded with reduced degradation of the image quality at the highlight portion.
摘要翻译：图像处理装置通过将与白色相对应的最小浓度数据或与由诸如打印机的图像形成装置可再生的最小浓度等级对应的最小可重复密度数据相同地改变输入多级像素数据来二进制化，由输入的多电平像素数据定义的密度具有这样的低电平，使其不能被图像形成装置再现。二值化所引起的错误反映在后续的二值化处理中，从而保留了整个图像的浓度，由此可以在亮点部分降低图像质量的劣化来记录具有高亮部分的图像。

摘要： In an image processing apparatus according to the present invention, the density of each pixel in a multi-level pixel block composed of a set of input multi-level pixel data is examined and a decision is made as to whether a pixel having a density which does not reach the minimum density below which printing is impossible, is present in the multi-level pixel block. If a pixel having a density below the minimum density is detected, the density of this pixel is distributed to another pixel position in the multi-level pixel block. In this manner, the number of pixels with a density which does not reach the minimum density below which printing is impossible, is reduced within each multi-level pixel block.

摘要： A method of and an apparatus for recording an image on a recording medium. A heat-sensitive sheet having a light-transmissive base sheet provided with a heat-fusible supercooled substance layer is made to abut a copy original such that the heat-fusible supercooled substance layer faces the original image to be copied while flashlight is projected onto the base sheet of the heat-sensitive sheet. Thus, the image portion of the copy original to be copied absorbs the light transmitted through the heat-sensitive sheet and thereby generates heat so that an adhesive area containing a pattern corresponding to the original image is formed on the supercooled substance layer. After the heat-sensitive sheet has been removed from the copy original, such an adhesive area is transferred to the recording medium owing to the adhesiveness of the adhesive area.
