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.
摘要翻译：一种用于在记录介质上记录图像的方法和装置。制成具有设置有热熔性过冷物质层的透光性基材片的热敏性片材，以将复制原稿贴合，使得热熔性过冷物质层面对要复制的原始图像，同时手电筒投射到热敏片的基片。因此，要复制的复制原稿的图像部分吸收透过热敏片的光，从而产生热量，使得在过冷物质层上形成包含与原始图像对应的图案的粘合区域。在热敏纸从复印原稿中取出之后，由于粘合剂区域的粘附性，这种粘合区域被转印到记录介质上。
