To solve the non-uniformity problem of multi Time Delay Integral Charge Couple Device (TDICCD) mosaic camera  several common non-uniformity correction methods are discussed. Secondly  a non-uniformity correction algorithm is proposed and implemented on Field-Programmable Gate Array (FPGA) platform. Firstly  the correction algorithm is designed. Finally  the generation and definition of non-uniformity are introduced  considering the fix-point processing ability of FPGA  the correction algorithm is optimized properly  and implemented on FPGA. The experimental results indicate that the non-uniformity can be decreased from 8.3%to 2.0% in 1s for 3-TDICCD mosaic camera's images with the proposed correction algorithm at 96TDI stage  proving that this correction algorithm is of high real-time performance  good practicality and satisfies the requirements of the target system. 2010 IEEE.

For multi-channel high-speed image data of certain space remote sensing camera  this paper proposed a new image data acquisition and storage system. First of all  the system uses Field-Programmable Gate Array(FPGA) controlling synchronous dynamic random access memory(SDRAM) array to realize the cache of image data  then according to the received commands  sends certain channel's image data to the acquisition card to write the image data into SCSI hard disk and implements the final storage. A Time Delay Integral Charge Couple Device(TDICCD) image data acquisition and storage system with five channels is developed  pixel clock rate is up to 96MHz  total effective data rate is up to 2.88Gb/s  single channel storage depth is up to 7810 lines. The experimental results indicate that this system work stably  high effectively which can meet the requirement of acquisition and storage of multi-channel high-speed TDICCD image data. 2010 IEEE.
