We present a color transfer method
which is designed to give fused multiband nighttime imagery a natural daytime color appearance in a simple and efficient way. Instead of using traditional nonlinear la space
the proposed method transfers the color distribution of the target image (daylight color image) to the source image (fused multiband nighttime imagery) in a linear color space named ICBCR. The ICBCR transformation is simpler than the la conversion
moreover
the IC BCR space is easily extended to image fusion. Our experiments on infrared and visual images show that the ICBC R based color transfer method works surprisingly well for transferring natural color characteristics of daylight color images to false color fused nighttime imagery. 2009 IEEE.

CCD noises and their causes are analyzed. Methods to control these noises
such as Correlated Double Sampling (CDS)
filtering
cooling
clamping
and calibration are proposed. To improve CCD sensor's performances
the IC
called Analog Front End (AFE)
integration of CDS
clamping
Programmable Gain Amplifier (PGA)
offset
and ADC
which can fulfill the CDS and analog-to-digital conversion
is employed to process the output signal of CCD. Based on the noise control approaches
the idea of chip design of linear CCD drive pulse generator and control interface is introduced. The chip designed is playing the role of (1) drive pulse generator
for both CCD and AFE
and (2) interface
helping to analysis and transfer control command and status information between MCU controller and drive pulse generator
or between global control unit in the chip and CCD/AFE. There are 6 function blocks in the chip designed
such as clock generator for CCD and AFE
MCU interface
AFE serial interface
output interface
CCD antiblooming parameter register and global control logic unit. These functions are implemented in a CPLD chip
Xilinx XC2C256-6-VQ100
with 20MHz pixel frequency
and 16-bit high resolution. This chip with the AFE can eliminate CCD noise largely and improve the SNR of CCD camera. At last
the design result is presented.
