摘要： The present invention is to reduce the change of the position of a picture screen due to the magnification/reduction of the picture screen and occurrence of losing a part of the picture screen. The picture screen signal of a main picture screen is switched to the picture screen signal of a sub or slave picture screen to be described later when the picture screen signal of the main picture screen is supplied to a change-over switch (2) from an input terminal (1). This picture screen signal is supplied to an image receiving tube (4) through an RGB drive circuit (3). The picture screen signal of the slave picture screen is supplied to a slave picture screen signal forming circuit (6) from an input terminal (5), reduced to an arbitrary size, taken out at the timing of an arbitrary position and the picture screen signal of the slave picture screen is formed. Further, a command signal from a command unit is supplied to a microcomputer 9 through an input terminal (8). In the microcomputer (9), if the command signal mentioned above is supplied to a central processing unit (CPU) (10), a display size control signal is formed by a display size change processing unit (11) (software) and at the same time a display position control signal is formed by a display position change processing unit (12) (software).
摘要翻译：本发明是为了减少由于图像屏幕的放大/缩小以及失去图像屏幕的一部分而出现的图像画面位置的变化。当主画面的画面信号从主画面的画面信号被提供给转换开关（2）时，主画面的画面信号被切换到稍后将要描述的子画面或从画面画面的画面信号输入端子（1）。该图像屏幕信号通过RGB驱动电路（3）提供给图像接收管（4）。从画面画面的画面信号从输入端子（5）被提供给从画面信号形成电路（6），在任意位置的定时被取出，任意大小被取出，画面信号形成从画面画面。此外，来自命令单元的命令信号通过输入端子（8）提供给微型计算机9。在微型计算机（9）中，如果将上述指令信号提供给中央处理单元（CPU）（10），则由显示尺寸变更处理单元（11）（软件）形成显示尺寸控制信号，显示位置改变处理单元（12）（软件）同时形成显示位置控制信号。

摘要： An image processing system 11 is arranged to produce data representing a combined image from foreground data F representing a foreground subject in front of a chroma backing and background data B representing a background image. The foreground data is processed and color corrected to produce first and second processed foreground data which is combined in a combiner 25 under the control of a first key K1. The background data is processed using a second key K2 to “cut” a “hole” in the background image. The processed background data and the combined foreground data are added together in an adder 44. A third key K3 is used to remove unwanted data from the added foreground and background data and to combine the resulting data with the processed background data in a combiner 45.
摘要翻译：图像处理系统11被布置为产生表示来自前景数据F的组合图像的数据，前景数据F表示色度背景前面的前景物体和表示背景图像的背景数据B. 对前景数据进行处理和颜色校正，以产生在第一密钥K1的控制下组合在组合器25中的第一和第二经处理的前景数据。使用第二键K2处理背景数据以“切割”背景图像中的“孔”。处理的背景数据和组合的前景数据在加法器44中相加在一起。第三密钥K3用于从所添加的前景和背景数据中去除不需要的数据，并将结果数据与处理后的背景数据组合在组合器45中。
