Abstract(s)
Endoscopy is an imaging procedure used for diagnosis as well as for some surgical purposes. The
camera used for the endoscopy should be small and able to produce a good quality image or video, to reduce
discomfort of the patients, and to increase the efficiency of the medical team. To achieve these fundamental
goals, a small endoscopy camera with a footprint of 1 mm × 1 mm × 1.65 mm is used. Due to the physical prop erties of the sensors and human vision system limitations, different image-processing algorithms, such as noise
reduction, demosaicking, and gamma correction, among others, are needed to faithfully reproduce the image
or video. A full image-processing pipeline is implemented using a field-programmable gate array (FPGA) to
accomplish a high frame rate of 60 fps with minimum processing delay. Along with this, a viewer has also
been developed to display and control the image-processing pipeline. The control and data transfer are done
by a USB 3.0 end point in the computer. The full developed system achieves real-time processing of the image
and fits in a Xilinx Spartan-6LX150 FPGA.
