    • The invention relates to an apparatus for obtaining an enlarged image of a part of the field of view of an IR camera. A device (4,6) for horizontal deflection and a device (5,17) for vertical deflection deflect IR rays (7) incident on the camera towards detector elements (8). These sense the field of view along parallel scanning lines costituting bands, and generate video signals so that the lines can be presented on a display screen (3). In accordance with the invention the device (5,17) for vertical deflection forms a smaller portion in height of the field of view than normal height thereof. The bands partially overlap each other so that the scanning lines in one band fall in the space between scanning lines in a preceding band. The bands are individually noted in the reading order in separate memory (C, D, E). The data for the lines falling in the space will be noted at addresses which do not correspond to their true position in the field of view. This is corrected by a readout device (31,32) which adjusts the readout to the image screen (3) such that the readout alternates between respective memory parts in the sequential order of the image lines.
    • 本发明涉及一种用于获得IR摄像机的视场的一部分的放大图像的装置。 用于水平偏转的装置(4,6)和用于垂直偏转偏转IR光线(7)的设备(5,17),其将相机朝向探测器元件(8)入射。 这些感测沿着并行扫描线的视野,并且产生视频信号,使得线可以呈现在显示屏幕(3)上。 根据本发明,用于垂直偏转的装置(5,17)形成比其正常高度更小的视场高度部分。 这些带部分地彼此重叠,使得一个带中的扫描线落在前一频带中的扫描线之间的空间中。 在分开的存储器(C,D,E)中以读取顺序分别记录频带。 落在空间中的线的数据将被记录在与其在视野中的真实位置不对应的地址处。 这通过读出装置(31,32)进行校正,该读出装置调整对图像屏幕(3)的读出,使得读出沿着图像行的顺序顺序在相应的存储器部分之间交替。
