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.

A Strategy of Real-Time Adjusting of Yaw Angle (SRTAYA) of space camera was proposed base on General Image-Quality Equation (GIQE). During space camera imaging
yaw angle which is caused by rotation of the earth and the gesture changing of satellite impacts integral aspect of TDI (Time Delay and Integration) CCD (Charge Couple Device)
so that the image quality degrades. For extending imaging time of space camera and enhancing image quality
yaw angle must be adjusted. The descending value of GIQE reflects the degrading quantity of image quality. The SRTAYA calculated an acceptable augmenting value of yaw angle according with a specific value of GIQE
which the degrading of image quality can't be neglected no longer. The example which actualized a practical orbit of satellite illuminated that the SRTAYA could limit the value of yaw angle less than 318.45". 2009 IEEE.

A Multi-Step Gain Adjusting Strategy (MSGAS) of space camera was proposed
which was used to get higher SNR (Signal-Noise Rate) image. When the space camera working in poor light condition
the CCD signal was so weak that it's difficult to get a clear image
to reduce the quantization noise and improve the SNR
we must amplify the CCD signal first and then quantize. The MSGAS was achieved by adjusting the gain of the CCD (Charge Couple Device) signal processor step by step
the upper limit and lower limit were set
if the MDN (Mean Digital Number) of a fixed length image data was not between the lower and upper limit
the gain was adjusted step by step. In the experiment
the upper limit
lower limit and the step were set
and the result of the experiment showed that MSGAS was robust and SNR was improved from 28 to 39. 2009 IEEE.
