影像记录仪是将数字形式存储的图像曝光到感光胶片上的一种设备。美国MGI公司最近推出的Solitaire系列影像记录仪有4pro、8pro、8xp、16xps等型号。曝光精度有2K、3K、4K、8K和16K线(在胶片幅面X或Y方向上)。Solitaire影像记录仪采用CRT产生白色光源,通过滤色片形成红、绿、蓝三色光,对应地曝光图像文件的红、绿、蓝三个通道。 Solitaire影像记录仪采用数字手段,实现曝光幅面和方向的控制、光栅枕形失真的校正、镜头光晕效应的校正,使曝光的精度、一致性和稳定性得到保障,并免除人工调整的烦劳。在曝光速度方面,Solitaire影像记录仪也有一定的优势,对于8xp,35mm、8K线为50s;102mm×127mm,8K线为90s;Academy格式电影每格为18s。 数字图像制作一般都需要使用扫描仪录入素材。扫描仪
Image Recorder is a device that exposes digitally stored images to photographic film. The United States recently introduced MGI Solitaire series of image recorders 4pro, 8pro, 8xp, 16xps and other models. Exposure accuracy is 2K, 3K, 4K, 8K and 16K lines (in the film format X or Y direction). The Solitaire image recorder uses a CRT to generate a white light source, and forms three colors of red, green and blue through the color filter, correspondingly exposing the red, green and blue channels of the image file. Solitaire image recorders use digital means to control the exposure width and direction, correct the pincushion distortion of the grating and correct the lens flare effect, so as to ensure the accuracy, consistency and stability of the exposure, and to avoid manual adjustment troubles. In terms of exposure speed, Solitaire video recorders also have some advantages, for 8xp, 35mm, 8K line for the 50s; 102mm × 127mm, 8K line for the 90s; Academy format movie every cell for 18s. Digital image production generally require the use of scanners to record material. scanner
