This paper put forward an available method aimed at the requirements of aerial camera with multi-mode. Driving schedules of interline transfer progressive scan KAI-2093 CCD sensor produced by Kodak corporation have been examined based on the structure and theory of dual-channel transmission. Three kinds of driving mode have been designed: binning
no-binning and TDI mode. The design takes the FPGA EP1C6Q240 produced by Altera corporation as the schedule generator to realize data cache and mosaics. QUARTUSII7.0 has been chosen as the software design platform. Driving schedule generator is described with VHDL. The design of data cache and mosaics has been fulfilled though simulation by Modelsim AE6.1b.Experimental results indicate that the schedule can output CCD signals at the speed of 60 frames/s
120 frames/s etc in binning mode
which can meet the requirements of moving target tracking with high speed; and can output full frame at the speed of 30 frames/s in no-binning mode;and does not affect image quality for long-time working in TDI mode. The system integration and anti-jamming capability have been improved.
