摘要：本发明激光束打印机利用新的灰度等级调节方式对原稿图象中的图象信息进行变换处理，形成灰度等级再现性好的记录图象。它具有三个特点：(1)灰度等级调节机构按照关系式把图象上任意取样点的基础浓度值(x)变换成记录图象上对应于上述采样点位置的象素浓度值(y)：中间灰度的记录图象是通过控制喷嘴中喷出的墨水量来改变记录象素点的直径；(3)是利用“迪沙”矩阵法而形成的点的密度调制图象。

摘要：根据本发明的方法，一帧图象显示在具有若干显示区的各个区域上，这些显示区是在具有若干显示行的显示屏上的行方向上被相邻地划定的，对各个显示行确定为在行方向上划定各个相邻显示区之间边界的边界数据，每个显示行中各个相邻显示区之间根据相应的边界数据而转换显示图象，从而能自由地确定边界和显示图象。本发明还提供一个廉价地实现这种图象显示方法的系统(图1和图2)。

摘要： A method for scanning and recording a plurality of original pictures by a picture reproducing machine in which desired parts of said plurality of original pictures of different reproduction magnification are simultaneously input and scanned, and at least parts of the desired portions are stored into memory so that they may be output, scanned and recorded simultaneously with different magnifications.

摘要： In this invention, the resolution is enhanced by first effectively decreasing the scan angle subtended between adjacent samples significantly below that of the Rayleigh limit to obtain an image blurred by the point spread function (or diffraction pattern) of the aperture. The next step is to process this blurred image to at least partially remove the blur. The unblurring process consists of convolving this finely sampled blurred image with a specially designed convolution mask. This mask effectively outputs an enhanced pixel at each step of the convolution. The mask simultaneously performs the equivalent of the following operations: (1) blur the image again; (2) subtract this reblurred image from the original image to form degradation estimates; and (3) add the estimates of the losses back into the original image.

摘要： A method is disclosed, according to which a plurality of original pictures are reproduced on a sheet of photosensitive material with a desired lay-out plan and each at a desired magnification factor. Although the method is suitable for a real time operation, any local irregularity of the picture signal at the pick-up end is absorbed by a writing control circuit before the signals are stored in a memory device in which the picture signals are arranged so as to be read out according to the desired lay-out plan. In addition to the utilization of the memory device, the motion of the pick-up heads is controlled for obtaining the desired magnification factors and for compensating the irregularities in their motion arising from their driving means.

摘要： A photocomposition system for composing typeface characters on a CRT display using a magnetic font disc formed of plural variable length character sectors wherein each sector includes successive storage cells containing all of the coded signals necessary to describe a single character image which signals may be retrieved and decoded for use by the CRT to create an optical image of the character. An optical scanner system is disclosed for optically determining the coordinate points on the boundary of an original character design for subsequent encoding into successive 3 bit binary codes representing successive end to end translational movements along the boundaries of the character design being encoded. The translational movements are selected from a subset of a total of 24 possible translational paths wherein the paths making up the subset is continually varying dependent on the general direction of the previous translational path. An electronic printer system is disclosed for retrieving single groups of character identifying translational command codes in response to text composing signals produced on a text editor. Each group of translational command codes is temporarily stored for decoding into coordinate signals used to access a high speed output memory having storage cells corresponding to the coordinates of the elemental areas (dots) on the CRT screen conceptually divided into an elemental area (dot) matrix. Following one complete decoding cycle, the data stored in the high speed output memory is used to cause the CRT to create an image of the character.
