Abstract:
The paper presents an algorithm for interpolation of the green pixels in frames from CMOS image sensor. The result is a monochrome frame calculated directly from the data from the primary BAYER matrix in the sensor. An algorithm and VHDL module work in real time were developed. The aim is simple and easy for usage algorithm, which uses small amount of macro-cells, to be implemented in FPGA. The algorithm is a part of optoelectronic system for measurements of the plane coordinates of a light spot. The system is based on PLD. The monochrome frame calculated with this module is used by other image processing algorithms in the system. FPGA XC3S400 by XILINX is used.
