14. Imaging software: With software copyright. This software integrates main functions of image processing software ,dynamic image acquisition and processing as well as static image processing, and has strong operability in fluorescence synthesis and processing, dynamic image measurement, and color correction. This software system can capture dynamic images in multiple formats and with various duration schemes, real-time shooting, timed shooting, real-time shooting and recording. It is also compatible with other cameras through the Directshow interface. The functional modules include eight modules: image processing, color control, fluorescence processing, histogram, image settings, static image processing, and measurement. They can set parameters, measure and draw for static and dynamic images and support multi-faceted image processing.
