摘要： Line drawing information expressed by characters and lines can be captured with an image scanner only when the information is printed on a sheet of paper having an appropriate size and the user can directly handle the paper. When the information is posted on a display panel or a wall, the acquisition of the information is impossible. Line drawings are different from ordinary video image in that the drawings are monochromic, their gradations are binarized, and their spatial frequencies are high. In order to input line drawings having these features, the image pick-up system of an electronic camera is provided with a mode switching means for monochromic high-resolution input, a means which converts picked-up line drawing information into monochromic binarized vector information, and a means which switches these two means at once at the time of picking up line drawing information.
摘要翻译：只有当信息被打印在具有适当尺寸的纸张上并且用户可以直接处理纸张时，才能用图像扫描仪捕获由字符和线表示的线条图。当信息发布在显示面板或墙壁上时，信息的获取是不可能的。线图与普通视频图像不同，因为图纸是单色的，它们的灰度被二值化，并且它们的空间频率高。为了输入具有这些特征的线条图，电子照相机的图像拾取系统设置有用于单色高分辨率输入的模式切换装置，将拾取线描绘信息转换为单色二值化矢量信息的装置，以及在拾取线条图画信息时立即切换这两种装置的装置。

摘要： A camera processing for changing the format of the image signals photo-electrically converted and digitized by a CCD into a predetermined output format and an image compression processing are performed. The operations for the processings are executed by an arithmetic means according to a program where the procedure of the operations are written. Thus a still picture is generated in a software manner. The degree of freedom of the signal processing in the image pickup device is raised, and accordingly the quality of image picked up by the image pickup device and the functions and operability of the device are enhanced without any additional units.
摘要翻译：执行用于将由CCD光电转换和数字化的图像信号的格式改变为预定输出格式和图像压缩处理的相机处理。处理的操作由算术装置根据写入操作过程的程序执行。因此，以软件方式生成静止图像。图像拾取装置中的信号处理的自由度提高，因此在没有任何附加单元的情况下增强了由图像拾取装置拾取的图像的质量以及装置的功能和可操作性。
