Abstract
In the last few years it is witnessed an unbowed trend to use digital cameras in more and more aspects of our everyday life. This has led to the development of a special group of devices that constitute combinations of embedded computers and video cameras; the so-called Smart Cameras. Smart Cameras are embedded platforms with small form factor, equipped with a single or multiple video sensors and enough computational resources to perform dedicated operations onboard and at site. In the context of this thesis, a hardware platform was developed, capable of controlling both the behaviour and output of Metal-Oxide-Semiconductor (CMOS) image sensors. The platform was developed using commercial-off-the-self products, where a CMOS image sensor was interfaced to a heterogeneous multicore processing module. Four applications were developed for this platform, embedding video streaming with signal processing operations, effectively transforming the hardware platform into a smart camera. In "De-noising during capture" application, multiple frames were averaged during acquisition to address the problem of image noise reduction. The second application, "Ultra-fast Spectrometer", utilizing only the rows of the image sensor’s array, converts the camera to an ultra-fast reconfigurable spectrometer. In "Human Vision Emulation", we developed an application in which both an overview of a scene (not in full resolution) accompanied with an area of interest in full resolution is simultaneously displayed in accordance with the human vision sensitivity model. Finally, in "Pseudocolor Mapper", the platform calculates a pseudocolor map based on the red to green channel ratio, which is an indicative index for locating veins in human body.
