      <abstract>
        <p>Conventional spectral imaging systems use a set of pre-determined filters to capture multi-band images. Liquid crystal tunable filters (LCTF) and active illumination allow reconfiguration of spectral sensitivities but these techniques have shortcomings such as latency due to multiple
 captures and the fact that the same filtering or illumination is applied to the whole frame of the image. There are emerging device technologies that allow independent adjustment of the filtering for each region or even at a pixel level of the imaging frame. The operation of such imaging systems
 is controlled by adapting to the scene based on scene analysis. Experiments were run by simulating a spectral imaging system which adjusts pixel sensitivities based on color information from the scene. As a result this new system exhibits superior performance compared to traditional spectral
 imaging systems in terms of color accuracy and imaging capture efficiency.</p>
