M., Santos, J., Morgado-Dias, F., & Wany, M. (2016, August). On the implementation of the gamma function for image correction on a endoscopic camera. In 2016 3rd International Conference on Electronic Design (ICED) (pp. 470-475). IEEE.http://hdl.handle.net/10400.13/5036This paper describes part of project that implemented the image processing of a CMOS sensor for endoscopic purposes. The sensor is a small sized device of 1x1mm2 and the image processing has been done inside a FPGA. This part of the work describes the implementation of the Gamma function with a balance between the resources needed and the accuracy. A linear piecewise solution was used that stores the values for 31 gamma functions with values ranging from 1 to 4 with 0.1 steps. The solution developed is 10 bit based, was coded in VHDL and is implemented in a Spartan 6 FPGA. The results show that it is an accurate solution that has a small footprint in terms of used resources.engGamma functionFPGAVHDLEndoscopy.Faculdade de Ciências Exatas e da Engenhariaconference object10.1109/ICED.2016.7804690
